Learjet 24

Private German

The accident occurred during a private IFR flight from Strausberg Airport (EDAY), Germany, to Bornholm Airport (EKRN), Denmark. Before the flight, an ATS flight plan was filed. Before takeoff at EDAY, the aircraft was refueled with 200 liters of jet fuel. According to the ATS flight plan, the pilot stated the total endurance to be 01:30 hrs and the Estimated Elapsed Time (EET) to be 00:30 hrs. The pilot informed the AIB DK that the estimated total endurance before takeoff at EDAY was approximately 01:00 hrs. The aircraft departed EDAY at 10:58. Enroute, the pilot observed a low fuel quantity warning light. Otherwise, the flight was uneventful until the approach to EKRN. At 11:32:00 hrs and at a distance of approximately18 nm southwest of EKRN, the pilot cancelled the IFR flight plan and continued VFR for a visual approach to runway 29. While descending inbound EKRN, the airspeed was decreasing. At 11:37:08 hrs, the pilot reported to Roenne Tower that the aircraft was turning final for runway 29. The aircraft was cleared to land. The wind conditions were reported to be 280° 19 knots maximum 29 knots. The aircraft was configured for landing (the landing gear was down and the flaps extended to 40°). On a left base to runway 29, both engines suffered from fuel starvation. At 11:39:18 hrs, the pilot three times declared an emergency. The aircraft entered a stall and impacted terrain in a field of sweet corn. A search and rescue mission was immediately initiated.

The crew was completing a local training flight at Pachuca de Soto Airport. After landing, the aircraft went out of control, veered off runway and eventually collided with a building housing a military canine unit, bursting into flames. The aircraft was destroyed and both pilots were killed.

Ameristar Jet Charter

On January 9, 2007, at 2323 central standard time, a Gates Learjet model 24F airplane, N444TW, serial number 348, was destroyed upon impact with terrain, about 18.8 nautical miles east of Guadalajara, State of Jalisco, in the Republic of Mexico. The airline transport-rated pilot and the commercial pilot functioning as first officer were fatally injured. The airplane was registered to the Sierra American Corporation of Wilmington, Delaware, and was being operated by Ameristar Jet Charter, Inc., of Addison, Texas, as Ameristar flight 878, a Title 14 Code of Federal Regulations Part 135 on-demand cargo flight. Night visual meteorological conditions prevailed and an instrument flight rules (IFR) flight plan was filed for the flight from Laredo, Texas. The cargo flight had originated in Laredo, Texas, at about 2210, with the Don Miguel Hidalgo International Airport (MMGL) near Guadalajara, Mexico, as its intended destination. Mexican Air Traffic Control personnel reported that the flight had approached MMGL from the north. At 2313, Guadalajara Approach Control cleared the flight to descend to 12,000 feet, provided an altimeter setting of 30.28, and told the flight to expect radar vectors for the ILS runway 28 approach to MMGL. After being provided a vector of 190 to intercept the localizer for the ILS runway 28 approach, there were communications between the flight and the controller to clarify which runway was active, and at 2318:00, the flight was given a right turn to a heading of 200 degrees. At 2318:56 the flight was cleared to descend to 10,000 feet, and at 2320:38, the flight was cleared to descend to 9,000 feet. The airplane was last observed on radar descending through 9,200 feet, while crossing the GDL VOR 085 degree radial.

Pavair

The aircraft departed controlled flight and crashed near Helendale, California. The captain and the first officer were killed, and the airplane was destroyed. The flight was operating under the provisions of 14 Code of Federal Regulations (CFR) Part 912 from San Bernardino County Airport (CNO), Chino, California, to Friedman Memorial Airport, Hailey, Idaho. Visual meteorological conditions prevailed for the flight, which operated on an instrument flight rules flight plan. A review of radar data and air traffic control (ATC) transcripts revealed that the flight departed CNO about 0858 and was cleared to climb to an altitude of 29,000 feet mean sea level (msl). About 0909:55, as the airplane was climbing through an altitude of 26,000 feet, the first officer requested a return to CNO. About 0910:01, the controller asked the first officer if he needed to declare an emergency, and the first officer replied that he did not. The controller then directed the flight crew to maintain an altitude of 24,000 feet. Mode C information for the flight showed that, from about 0910:12 to about 0910:59, the airplane descended from 26,500 to 24,000 feet at a rate of about 2,000 feet per minute (fpm). About 0911:08, the controller cleared the flight directly to HECTOR (a navigation fix) and asked the first officer to confirm that the airplane was in level flight at an altitude of 24,000 feet. The first officer did not respond. Radar data showed the airplane descending through 23,000 feet at a rate of about 6,500 fpm about that time. About 0911:24, while the airplane was descending at a rate of about 10,000 fpm, the first officer stated, “we’re declaring an emergency now.” No further transmissions were received from the airplane. No radar data were available after about 0911:35. Starting about 0911:47, mode C information was invalid. The airplane impacted high desert terrain (an elevation of 3,350 feet) about 3 miles southeast of Helendale. The accident site was located about 46 nautical miles (nm) north of CNO. A witness to the accident, who was located about 4.5 miles northwest of the accident site, stated that, after hearing the sound of a jet flying high overhead, he looked up and observed the accident airplane flying straight and level below a high, overcast cloud layer. He stated that the airplane then pitched “nose down a little” and “straightened again.” He also stated that, shortly thereafter, he observed the airplane’s nose pitch “straight down” until it impacted terrain. The witness reported that he did not notice whether the airplane was rotating about its longitudinal axis during the descent, but he did indicate that the airplane appeared to be intact without any components separating from the airplane during the descent. The witness added that he did not observe any smoke or fire before the airplane impacted terrain and that the airplane exploded into a “mushroom cloud” when it impacted terrain. San Bernardino County firefighters, who were performing controlled burns near the accident site, reported hearing an explosion about the time of the accident. The firefighters reported that they looked toward the direction of the explosion and saw a rising smoke cloud. None of the firefighters observed the airplane before the sound of the explosion. The firefighters drove to the accident site and were the first to arrive there. The firefighters extinguished small fires that had erupted as a result of the crash.

Multi-Aero

The turbojet airplane was destroyed during a forced landing and post accident fire after a loss of power in both engines during takeoff climb. The pilot reported that both engines operated normally during taxi and pre-takeoff checks. He reported that, "We rotated positive rate gear up, V2 plus 30 flaps up, and at that point we struck birds taking No. 2 engine out. Upon losing No. 2 engine I advanced thrust levers forward and realized that the No. 1 engine was only producing approximately 70% RPM with EGT over read line." He executed a forced landing to a field and the crew and passengers evacuated the burning airplane. The copilot reported, "At approximately 500 to 1,000 ft. above ground level, I observed a large flock of birds straight ahead of us, and then passing just off our nose to the left side. I immediately heard an engine flameout. As I started to go to the checklist for single engine operations, I quickly realized that we were loosing airspeed and unable to maintain altitude. The PIC said we were going down and heading for the best emergency-landing stop." The Cockpit Voice Recorder (CVR) recorded the pilot stating, "We hit a bird," and the copilot stating, "Yep," immediately following the CVR recording a "sound similar to decrease in engine RPM." The inspection of the airplane's fuel system, pneumatic system, engines, fuel controls and fuel pumps revealed no pre-impact anomaly. No physical evidence of bird ingestion was found in either engine. A CVR sound spectrum plot and a flight profile analysis revealed that one engine flamed out almost immediately after the sound of a "thump" on the CVR. The other engine's speed decreased and experienced stalls until the engine speed was reduced to flight idle. The original engine certification tests indicated that compressor stalls occurred when a 2-4 ounce starling was shot ingested into the engine, but physical damage from bird ingestion was very slight due to the all steel construction and geometry of the engine. Engine flameouts, however, were not recorded during the certification tests. A wildlife specialist conducted a bird count at the accident airport two days after the accident occurred, and he reported counting a flock of about 800 European Starlings.

Air Cargo Express

The twin-turbojet, transport-category airplane was destroyed when it departed controlled flight during descent into its final destination and impacted terrain. The flight was cleared to descend from FL 390 to 10,000 feet, and the flight crew established a 4,000-foot/minute descent. As the airplane descended through FL 219, air traffic control requested the pilot contact approach control. However, the pilot read back an incorrect frequency and spoke an unintelligible word. The controller attempted to correct the pilot; however, no additional communications were received from the flight crew. Located within a pause in the pilot's last transmission, a 1680 Hz frequency could be heard for 0.1 seconds. There are only two systems in the airplane with aural warning systems within that frequency range; the cabin altitude warning, and the overspeed warning (both systems were destroyed during the accident sequence). Shortly after the last transmission from the pilot, radar data depicted the airplane climbing back up to FL 231 before entering a steep and rapid descent. A performance study indicated that just prior to the loss of control, the airplane exceeded its maximum operating airspeed of 300 knots calibrated. However, according to the manufacturer, the airplane had been successfully flown at airspeeds up to 400 knots calibrated without loss of control. The right wing and sections of the right horizontal stabilizer/elevator separated from the airplane just prior to its impact with terrain and were located approximately 200-250 feet from the main impact crater. No anomalies with the airframe or engine were found that would have led to the loss of control. A cockpit voice recorder was installed in the accident airplane; however, it did not record the accident flight.

NASA - National Aeronautics %26 Space Administration

The copilot inadvertently induced a lateral oscillation and lost control of the airplane while practicing touch-and-go landings. The pilot made the first touch-and-go. The copilot successfully made the second touch-and-go. The copilot attempted the third touch-and-go. At 50 feet, he disengaged the yaw damper and entered a pilot induced lateral oscillation. The airplane rapidly decelerated and developed a high sink rate. The airplane dragged the right tip fuel tank, which separated from the airplane, and the airplane bounced back into the air. The airplane landed hard, the main landing gear collapsed, and the airplane skidded to a stop off the right side of the runway. Both pilots and the passenger deplaned through the main entry door. The pilot-in-command had not demonstrated the handling characteristics of the airplane with the yaw damper off, and he felt he did not react quickly enough to prevent the accident.

Dolphin Aviation

The pilots stated that approach and landing were normal. During landing rollout, about 2,000 feet down the runway, the brakes became ineffective. The aircraft continued to roll off the end of the runway, down an embankment, across a 4 lane road, and came to rest in a drainage ditch. Post-crash examination of the main landing gear brakes showed that 3 out of the 4 brake assemblies were worn beyond allowable limits and all 4 antiskid wheel generators were not producing voltage within the allowable limits. The outboard right main tire had failed during landing roll do to the antiskid becoming inoperative due to the low voltage of the wheel generator. The airplane had received an A-1 through A-6 inspection 2 days before the accident and this was the first flight since the inspection. The A-5 inspection requires inspection of the landing gear brake assemblies for wear, cracks, hydraulic leaks, and release.

Manacá Taxi Aéreo

The aircraft departed São Paulo-Congonhas on a training flight to Ribeirão Preto-Leite Lopes Airport, carrying five crew members, instructor and pilots. On final approach to runway 18, during the last segment, just prior to touchdown, the aircraft rolled to the right, causing the right wing tip to struck the runway surface. The pilot-in-command overcorrected, the aircraft went out of control and crashed 420 metres past the first impact, bursting into flames. All five occupants were killed.

Mexican Navy - Armada de México

During the takeoff roll at Mexico City-Benito Juárez Airport, at Vr, the pilot-in-command initiated the rotation but the aircraft failed to respond. For unknown reasons, the crew wait few seconds and attempted a second rotation but the aircraft still failed to respond. The captain decided to abort the takeoff and started an emergency braking procedure, deploying the tail parachute. Approaching the end of the runway, the pilot made a left turn then the aircraft veered off runway, lost its undercarriage and came to rest 150 metres further, bursting into flames. All seven occupants escaped uninjured while the aircraft was damaged beyond repair.

Panther Aviation

During landing roll, the airplanes normal braking system failed as a result of hydraulic fluid leak(s). At the pilot's request, deployment of the drag chute and application of the emergency braking system was performed by the first officer. According to the first officer, application of the emergency brakes caused the airplane to yaw. The first officer then pulled up on the emergency brakes handle followed by re-application of braking pressure. This action took place several times during the landing roll. Gates' Learjet Flight Training Manual (Page 105) states, 'In using the emergency brake lever, slow steady downward pressure is required. Each time the lever is allowed to return upward to the normal position, nitrogen is evacuated overboard. Brace your hand so you will not allow the lever to move up and down inadvertently on a bumpy runway.' The airplane overran the end of the runway and collided with the Instrument Landing System back course antennae.

Aerodinamo del Pacifico

On approach to Tampico-General Francisco Javier Mina Airport, the crew established on the ILS. The aircraft descended below the glide and MDA until it struck the ground and crashed in a lagoon located 12,8 km short of runway. A pilot and two passengers were killed while five other occupants were injured. The aircraft was destroyed.

Air Cargo Express

According to the pilot, the airplane '...began moving to the left side of the runway...' immediately upon touchdown. He attempted to abort the landing but the airplane contacted snow at the runway's left edge. The airplane exited the runway's left edge and slid sideways, about 300 yards.

Medicorp

On approach to Posadas-Libertador General José de San Martín Airport, the crew encountered low visibility due to foggy conditions. Despite the fact he was unable to establish a visual contact with the runway, the crew decided to continue the approach when the aircraft landed on the taxiway parallel to the runway. After a course of 800 metres, the aircraft overran, lost its undercarriage and came to rest. Both pilots escaped uninjured and the aircraft was written off.

Scibe-Airlift Zaïre

The crew was cleared for a night visual approach to Kinshasa-N'Djili Airport. Weather conditions were good with a visibility over 10 km. On approach, ATC asked the crew to turn on the approach lights. Shortly later, the aircraft struck the ground and crashed 20 km short of runway 24 threshold. Both pilots were killed.

Crown Center Aviation

The crew departed Memphis on a flight to Addison, Texas. En route, the crew was cleared to climb to FL300 but the aircraft continued to climb without authorization until FL440. ATC tried to contact the crew without success. It was decided to dispatch a USAF Northrop T-38 Talon fighter and his pilot confirmed that the cockpit windows were covered by frost and that he was unable to contact the crew. The aircraft continued its route to the south, entered the Mexican airspace and few minutes later, after both engines failed due to fuel exhaustion, the aircraft entered a dive and crashed near Cuatro Ciénegas. The aircraft disintegrated on impact and both pilots were killed, among them the NASA astronaut-candidate Susan Reynolds aged 27.

Transamérica Táxi Aéreo

On final approach to Macaé Airport, both engines lost power simultaneously. The aircraft stalled and crashed few hundred meters short of runway. Both pilots were killed while four other occupants were injured.

Kalitta Charters - Kalitta Services

After refueling in Denver, the medical evacuation flight was diverted from Aspen to Eagle to enplane the patient. IFR flight to Eagle was uneventful and radar service was terminated after the controller cleared the flight for the lDA-A approach to the Eagle Airport which shows a 239° inbound course. The last radio contact occurred when the crew replied 'we're 8 to 10 out and it's clear ahead' to Eagle radio in answer to a request for a base report. The flight collided with an 8,022 foot msl mountaintop bearing 298°, 3.88 miles from the airport while in the approach configuration. The safety board believes the flight was circling to land on runway 07, and the dark night prevented required visual lookout to avoid terrain obstructions. The Jeppesen approach charts used by the flightcrew did not accurately depict terrain obstructions within the 5-mile radius of the airport as stipulated in their legend. The safety board believes this could have mislead the flightcrew. All three occupants were killed.

Jet Way Enterprises

The crew attempted an ILS approach with indefinite ceiling and RVR down to zero due to fog. The copilot was at controls. During a missed approach, the aircraft contacted runway where glideslope intersects terrain with sufficient force to shear all three landing gear. The right engine spolled down during climbout. The crew diverted to Detroit-Metropolitan Airport and complete a gear up landing. Minor fire broke out during ground slide. Both altimeters bench checked within tolerances. All three crew escaped with minor injuries.

My Wife Yacht Sales

The pilot stated he made a normal approach and landing but on rollout discovered he had no brakes. The aircraft traveled off the left side of the runway and collided with a fence surrounding a ballpark. Post crash examination of the hydraulic system revealed that the hydraulic reservoir was empty and the main accumulator and the thrust reverser accumulator had no air charge. All four occupants escaped uninjured.

Flight International

The crew was engaged in a military exercise consisting of an aerial attack of a US Navy vessel. In unknown circumstances, the aircraft collided with a second Flight International Learjet 35 registered N39DM. Both aircraft crashed in the sea about 27 miles southeast of San Clemente Island and all four crew members were killed.

Air Provence International

Crashed upon landing at Toulouse-Blagnac Airport. There were no casualties.

ERA Aviation

During arrival to pick up a medevac patient, the flight was cleared for an LDA-1 runway 08 approach via the Asort transition. Thus, the pilot should have continued southeast on J-541 toward the SSR vortac and intercepted the localizer (loc) at Asort; then track inbound on the loc (062°), using I-JDL frequency 109.9 MHz (frequency for loc and co-located DME). After Asort, minimum altitude was 6,500 feet to Dibol intersection, 5,100 feet to Lynns intersection and 3,400 feet to the faf at Barlo intersection. DME from I-JDL to the intersections was: 18.2, 13.5 and 8 miles. DME from SSR (south of loc track) to the intersections was 11.2, 12.7 and approximately 16 miles. Flight reported Asort inbound while descending thru approximately 9,500 feet. Last radio call was 30 seconds later while descending thru 8,200 feet, 14 miles west of Dibol. Approximately 4 miles west of Dibol, aircraft impacted mountain side at 3,500 feet msl. No preimpact mechanical malfunction was found. There was evidence that both nav's were tuned to 109.9 MHz, but DME control head was inadvertently left in 'hold' position (locking DME to SSR rather than I-JDLl) and crew began a premature descent. Juneau weather was in part: 600 feet scattered, 3,000 feet overcast, 7 miles visibility. Pilot-in-command was currently flying both Learjet and DHC-7. All four occupants, two pilots and two doctors, were killed.

ERA Aviation

During a night arrival, the flight was on an instrument approach to the Gulkana Airport when radio contact with the aircraft was lost. A search was initiated and the wreckage was found 7.4 miles north of the terminal VOR on the 330° radial. The inbound course for the VOR runway 14 approach was on the 315° radial. An on-scene exam revealed the aircraft was tracking inbound when it collided with trees, crashed and burned about 2.4 miles before reaching the final approach fix. Both engines were operating during impact and both had ingested considerable tree material. No preimpact mechanical failure was evident. The captain and 1st officer were currently responsible for flying both the Learjet and DHC-7 aircraft. This was the captain's 1st day of work after returning from a vacation trip to Hawaii (approximately 1-1/2 weeks). The 1st officer had an adequate period for crew rest prior to reporting for work; however, he had previously been working a varied schedule. The operator repeatedly shifted pilots from 14 cfr 135 rest/duty requirements to those of 14 cfr 121. All three occupants were killed.

Euralair International

The crew started the descent to Paris-Le Bourget when the aircraft went out of control, entered a dive and crashed in an open field located in Provins, about 77 km southeast of Le Bourget Airport. The aircraft was destroyed and both occupants were killed.

Macton Corporation

While executing a night visual approach to runway 09 in visual meteorological conditions the aircraft was allowed to descend; crashing into water 2 miles short of the runway. The pilot was not familiar with the airport and failed to make use of a full instrument landing system and visual approach slope indicating system which were operational for runway 09 at the time of the accident. The pilot stated there were no mechanical malfunctions with the aircraft which attributed to the accident. The aircraft was equipped with a radar altimeter system which also was not used by the pilot. The pilot performed two missed approaches because the airport was not in sight. The accident occurred during the 3rd attempt. Neither the pilot-in-command nor the copilot were properly certificated for the flight.

Clay Lacy Aviation

The aircraft, a Gates Learjet 24B, modified by a Howard/Raisebach Mark II conversion, was cleared for takeoff on runway 28L. Tower personnel estimated that the aircraft rotated for takeoff at 3,200 feet down the runway and was at approximately 200 feet agl when the pilot was instructed to contact departure control. Witnesses observed the aircraft climbing in a wings level attitude when it entered the broken cloud layer at about 600 feet agl. Moments later, the aircraft was observed descending out of the clouds at a steep angle and in a left wing low/nose down attitude. The aircraft impacted between runway 28L and 28R, approximately 10,000 feet from the approach ends. Witnesses reported that the engines sounded like they were operating at a high power setting. An exam of the engines revealed evidence that both were at or above 92% power at impact. No preimpact part failure/malfunction was found. Records revealed two autopilot discrepancies on 10/4/84; one induced the roll mode was sensitive; the other induced the autopilot intermittently rolled the aircraft into a standard rate left bank when engaged. Reportedly, the autopilot would not have been used for takeoff. All three occupants were killed.

Líder Taxi Aéreo

On approach to Florianópolis-Hercílio Luz Airport, the crew failed to realize his altitude was too low when the airplane struck Mt Sangão located 23 km from the airfield. All four occupants were killed.

Gee Bee Aero

The aircraft departed on a sales demo flight to Monterey, CA with potential buyers aboard. En route, the destination was changed to Avalon, CA. Unicom advised the crew of the wind direction and speed on downwind. Witnesses reported the aircraft was slightly high on final, but said the pilot corrected the angle of descent. The aircraft touched down approximately 500 feet down the runway, which was crowned (sloped upward for approximately the 1st 2,000 feet, then leveled off). The crew could not see the end of the runway at touchdown. The thrust reversers were deployed approximately 1,000 feet after touchdown. Witnesses heard the engine sound increase, then decrease, then increase again as the aircraft went off the runway and over a 90 feet bluff. Fire erupted immediately. Within 3 minutes, airport personnel arrived with firefighting equipment, but they were not trained as firefighters and did not try to stop the fire for fear of an explosion. No evidence of a mechanical failure/malfunction was found. Found left flap extended, left spoiler retracted and locked, tire marks on runway. Estimated gross weight: 11,500 lbs. Computed landing distance over a 50 feet obstacle: 3,100 feet. The aircraft was destroyed and all six occupants were killed.

Executive Jet Aviation - USA

On final approach to Puerto Vallarta-Licenciado Gustavo Díaz Ordaz Airport, the crew descended below the glide until the airplane struck the ground and crashed short of runway threshold. All four occupants were injured and the aircraft was destroyed.

Duncan Aviation

After the two aircraft were established at 14,000 feet during a target towing operation, N13MJ (lead aircraft) maintained straight and level flight on autopilot while N47MJ (chase) came up along the left side to observe the target on the left wing. While moving forward and looking out the right window to see a light on the target, the chase pilot lost sight of the lead aircraft. He reduced power and in the process of backing away, the chase aircraft struck the top of the flying tail of the lead acft with its radome jamming the flying tail. The lead aircraft pitched down, lost about 6,000 feet and then recovered. During the emergency landing of the lead aircraft, it pitched over when the gear was extended on short final, struck the ground hard short of the runway, bounced and started porpoising. As the pilot added power for a go-around, the aircraft started to roll. Power was reduced and about 5,000 feet down the runway, the gear collapsed causing the aircraft to veer off the runway. The pilot of the chase aircraft was not military trained and had no formal formation flight training.

Sky Train Air

While on a return flight to their company headquarters in McAllen, Texas, from Thermopolis, Wyoming, the president of Sky Train Air Inc., the chief pilot, and another company pilot stopped in Casper, Wyoming, for fuel. The lineman noted a fuel imbalance when 320 gallons of fuel were added to the left wing and only 260 gallons of fuel were added to the right wing tanks. According to the lineman, the crew was aware of the imbalance. A total of 585 gallons of Jet-A with Prist (anti-ice additive) was supplied which filled the wing tanks to capacity. No fuel transferring was necessary during the refueling. The lineman stated that he believed the fuselage tank was full because the nosegear strut was extended 6 to 12 inches. We stated a ground power unit was used to start the engines and he did not notice any difficulties with the aircraft during the crew's preflight checks. The flight plan filed by the president, reported to be the pilot-in-command, as follows: IFR to McAllen, Texas, at Flight Level (FL) 450, true airspeed 450 knots, Airway J170 to Denver, J17 to Amarillo, J17 to San Antonio, J25 to Corpus Christi, direct McAllen; time en route 2 hours 20 minutes with 3 hours 40 minutes of fuel on board. A weather briefing was not given to him because he had reported that he already had the weather information. The crew called the Casper Air Traffic Control Tower for taxi clearance at 1352:08 and began its departure from runway 21 at 1357:02. At 1449:39, while in cruise flight at FL 450, the flightcrew made initial radio contact with Sector 71 of the Albuquerque Air Route Traffic Control Center (ARTCC). The aircraft was "squawking" transponder code 0670. About 1458, a new controller took over the radar and data positions. At 1459:36, he issued a frequency change to which the crew did not respond. At the time, the controller noticed no transponder target reply from the aircraft. Until 1501:39, he made several attempts to contact the aircraft, but received no response. Albuquerque ARTCC radar computer data showed that radar contact with the aircraft was lost at 1458:07 at FL447. Five witnesses at Felt, Oklahoma, located in the southwest portion of the Panhandle, heard an aircraft overhead at a very high speed. One witness stated that he heard a vibration sound which indicated to him the aircraft was overspeeding. Another witness stated that the aircraft was about lo break the sound barrier. Of the five witnesses interviewed, only one saw the aircraft - and only momentarily - and he stated the aircraft was in about a 45° descent angle and the wings appeared to be rocking up and down. All the witnesses stated that they heard an explosion and saw a mushroom cloud of black smoke erupt when the aircraft crashed to the ground. The accident occurred at approximately 1502LT. The aircraft crashed 2.5 miles southwest of Felt, Oklahoma. All three occupants were killed.

While approaching Rio de Janeiro-Santos Dumont Airport, the captain decided to abandon the landing and initiated a go-around manoeuvre after he has been informed about the fact that the runway was wet. He followed a holding circuit for about 30 minutes then started an approach to Rio de Janeiro-Galeão Airport when the airplane struck power cables and crashed few km from the airfield. The aircraft was destroyed and all three occupants were killed. At the time of the accident, the visibility was limited due to low clouds.

Machinery Buyers Corporation

A Gates Learjet 24, N454RN, operated as a corporate flight by Machinery Buyers Corp., crashed following takeoff from runway 20L at DeKalb-Peachtree Airport, Atlanta, Georgia. The aircraft was destroyed by impact and fire. The two crewmembers and five passengers were fatally injured and one person on the ground sustained serious burns. An apartment building was damaged, three parked vehicles were destroyed, and another vehicle was damaged by impact and fire. The pilot had filed an Instrument Flight Rules (IFR) flight plan from Atlanta, Georgia, to Miami, Florida, with a proposed departure time of 09:50 and an en route altitude of Flight Level 410. The flight was cleared for takeoff from runway 20L at 10:10. The weather at the time of the accident was overcast, with ceiling 500 feet, visibility 4 miles in fog and smoke, wind 060° at 4 knots, altimeter setting 30.20 inches. Ground witnesses stated that the airplane had made a normal take-off, but was trailing blue-white or blue-gray smoke when it crossed the airport boundary. The following conversation with the flight was recorded by the airport control tower: Tower - "Lear 454RN it appeared the left engine laid a pretty good layer of smoke out of the left side there for approximately 300 or 400 feet." 454RN - "We just hit some birds." Tower - "Roger, you turning to land?" 454RN - "Don't believe we're gonna make it." (Last transmission by the crew. The aircraft climbed to a height about 250 to 300 feet above the ground before it started to settle in a nose-high attitude. The airplane collided initially with the roof of a three-story apartment building, approximately 2 miles south-southwest of the airport. The wreckage came to rest in a wooded ravine adjacent to a busy highway, 165 feet southwest of the damaged building. The airplane's takeoff path was over a residential area which contained numerous apartment complexes, shopping centers, and busy thoroughfares. A suitable emergency landing site was not available. The airplane's windshield and center post contained bird residue and bird feathers. After the accident, the remains of 15 cowbirds were found within 150 feet of the departure end of runway 20L. Both engines showed distortion and foreign object damage to the compressor rotor assemblies. Foreign material obstructed approximately 75 percent of the cooling air ports of the first-stage turbine nozzles.

Following an uneventful flight from Saint Joseph, Missouri, the crew started the descent to Detroit-Willow Run Airport. After a wrong approach configuration, the crew misjudged distance and speed during the last segment, causing the aircraft to land too far down the runway. After touchdown, the airplane was unable to stop within the remaining distance and the captain decided to initiate a go-around manoeuvre but this was too late. The airplane overran, struck the localizer antenna then crashed on the ILS building. Both pilots were killed while the passenger was seriously injured.
