Embraer EMB-120 Brasília

Berry Aviation

The twin engine airplane departed Detroit-Willow Run (Ypsilanti) Airport at 2337LT on March 6 on a cargo service to Akron-Canton Airport, carrying two pilots and a load of various goods. After takeoff, the crew encountered technical problems and declared an emergency. He completed two low passes in front of the tower, apparently due to gear problems. Eventually, the aircraft belly landed at 0008LT and came to rest on runway 05R. Both pilots evacuated safely and the aircraft was damaged beyond repair.

African Express Airways

On approach to Bardale Airstrip, the twin engine aircraft struck the ground and crashed 5 km from the airport, bursting into flames. The aircraft was totally destroyed and all five occupants were killed. The crew was enroute from Mogadiscio to Bardale with an en route stop in Baidao, carrying medical supplies and mosquito nets.

Guicango

The twin engine aircraft departed Dundo Airport at 1658LT on an ambulance flight to Luanda, carrying three doctors, one patient from South Africa and three crew members. About 15 minutes into the flight, the crew reported engine problems when one of them caught fire shortly later. The airplane went out of control and crashed in an open field located near Cuilo, about 170 km southwest of Dundo. All seven occupants were killed.

RusLine

Following an uneventful flight from Ulyanovsk, the crew started the descent to Moscow-Domodedovo Airport. While following the approach checklist, the crew realized that the nose gear failed to deploy and remained stuck in its wheel well. Several attempts to lower the gear manually failed and the crew eventually decided to carry out a nose gear-up landing on runway 32L. After a holding circuit of about 45 minutes, the aircraft landed then slid on its nose for few dozen metres before coming to rest. All 31 occupants evacuated safely and the aircraft was damaged beyond repair.

Guicango

On final approach to Lucapa, the crew encountered technical problems and was forced to shut an engine down for unknown reason. After touchdown, the aircraft went out of control and veered off runway to the left. While contacting rough terrain, the aircraft lost its undercarriage and came to rest on its belly with severe damages to both wings, engines and fuselage. Three passengers were slightly injured.

Associated Aviation

The crew discussed some concerns about the aircraft prior to departure but at this time we are not prepared to elaborate on those concerns as there remains a lot of work to complete on the CVR analysis in order to determine the specific nature of the crew’s concerns. Associated 361 was cleared for take-off on runway one eight left at Lagos international airport. The wind was calm and weather is not considered a factor in this accident. Approximately 4 seconds after engine power was advanced to commence the take-off roll, the crew received an automated warning from the onboard computer voice which consisted of three chimes followed by “Take-off Flaps…Take-off Flaps”. This is a configuration warning that suggests that the flaps were not in the correct position for take-off and there is some evidence that the crew may have chosen not to use flaps for the take-off. The warning did not appear to come as any surprise to the crew and they continued normally with the take-off. This warning continues throughout the take-off roll. As we are in the process of verifying the accuracy of the flight data, we have not yet been able to confirm the actual flap setting however we expect to determine this in the fullness of time. It was determined from the CVR that the pilot flying was the Captain and the pilot monitoring and assisting was the First Officer. The ‘set power‘ call was made by the Captain and the ‘power is set’ call was confirmed by the First Officer as expected in normal operations. Approximately 3 seconds after the ‘power is set’ call, the First Officer noted that the aircraft was moving slowly. Approximately 7 seconds after the ‘power is set’ call, the internal Aircraft Voice warning system could be heard stating ‘Take off Flaps, Auto Feather’. Auto feather refers to the pitch of the propeller blades. In the feather position, the propeller does not produce any thrust. The FDR contains several engine related parameters which the AIB is studying. At this time, we can state that the Right engine appears to be producing considerably less thrust than the Left engine. The left engine appeared to be working normally. The aircraft automated voice continued to repeat ‘Take-off Flaps, Auto Feather’. The physical examination of the wreckage revealed that the right engine propeller was in the feather position and the engine fire handle was pulled/activated. The standard ‘eighty knots’ call was made by the First Officer. The first evidence that the crew indicated that there was a problem with the take-off roll was immediately following the ‘eighty knots’ call. The First Officer asked if the take- off should be aborted approximately 12 seconds after the ‘eighty knots’ callout. Our investigation team estimates the airspeed to be approximately 95 knots. Airspeed was one of the parameters that, while working in the cockpit, appeared not to be working on the Flight Data Recorder. We were able to estimate the speed based on the radar data that we synchronized to the FDR and CVR but it is very approximate because of this. In response to the First Officer’s question to abort, the Captain indicated that they should continue and they continued the take-off roll. The crew did not make a ‘V1’ call or a Vr’ call. V1 is the speed at which a decision to abort or continue a take-off is made. Vr is the speed at which it is planned to rotate the aircraft. Normally the non-flying pilot calls both the V1 and the Vr speeds. When Vr is called the flying pilot pulls back on the control column and the aircraft is rotated (pitched up) to climb away from the runway. During the rotation, the First Officer stated ‘gently’, which we believe reflects concern that the aircraft is not performing normally and therefore needs to be rotated very gently so as not to aerodynamically stall the aircraft. The First Officer indicated that the aircraft was not climbing and advised the Captain who was flying not to stall the aircraft. Higher climb angles can cause an aerodynamic stall. If the aircraft is not producing enough overall thrust, it is difficult or impossible to climb without the risk of an aerodynamic stall. Immediately after lift-off, the aircraft slowly veered off the runway heading to the right and was not climbing properly. This aircraft behavior appears to have resulted in the Air Traffic Controller asking Flight 361 if operation was normal. Flight 361 never responded. Less than 10 seconds after rotation of the aircraft to climb away from the runway, the stall warning sounded in the cockpit and continued to the end of the recording. The flight data shows characteristics consistent with an aerodynamic stall. 31 seconds after the stall warning was heard, the aircraft impacted the ground in a nose down near 90° right bank.

Inter Iles Air

The aircraft was on its way from Moroni-Hahaya-Iconi-Prince Saïd Ibrahim Airport to the Ouani Airport located on the neighboring island of Anjouan. Shortly after take off from runway 20, while in initial climb, the captain informed ATC about technical problem and elected to return. He realized he could not make it so he attempted to ditch the aircraft some 200 metres off shore, about 5 km from the airport. All 29 occupants were rescued, among them five were slightly injured.

Nationale Régionale Transport - NRT

The aircraft was performing a regular schedule flight from Libreville to Port Gentil. The approach was completed in poor weather conditions with low visibility (1,000 metres) due to heavy rain falls. After touchdown, the aircraft did not decelerate as expected, skidded on runway, overran and came to rest down a slight embankment in shallow water. Both engines caught fire and both wings were partially torn off. All 30 occupants evacuated safely while the aircraft was damaged beyond repair. A thunderstorm was passing over the area at the time of the accident.

Angola Air Force - Força Aérea Nacional Angolana

Shortly after take off from Huambo-Albano Machado Airport, the twine engine aircraft stalled and crashed near the runway end, bursting into flames. All four crew and two passengers survived while 17 passengers were killed. There were 11 officers, three generals and six civilians on board. This Embraer Brasilia was the most recent built in service.

Airnorth Regional - RegionalLink

Aircraft crashed moments after takeoff from runway 29 at Darwin Airport, Northern Territory, fatally injuring both pilots. The flight was for the purpose of revalidating the command instrument rating of the pilot under check and was under the command of a training and checking captain, who occupied the copilot’s seat. The takeoff included a simulated engine failure. Data from the aircraft’s flight recorders was used to establish the circumstances leading to the accident and showed that the pilot in command (PIC) retarded the left power lever to flight idle to simulate an engine failure. That introduced a simulated failure of the left engine and propeller autofeathering system. The increased drag from the ‘windmilling’ propeller increased the control forces required to maintain the aircraft’s flightpath. The pilot under check allowed the speed to decrease and the aircraft to bank toward the inoperative engine. Additionally, he increased power on the right engine, and engaged the yaw damper in an attempt to stabilize the aircraft’s flight. Those actions increased his workload and made control of the aircraft more difficult. The PIC did not restore power to the left engine to discontinue the manoeuvre. The few seconds available before the aircraft became uncontrollable were insufficient to allow ‘trouble shooting’ and deliberation before resolving the situation.

Rico Linhas Aéreas - Rondonia Importaçao e Comercio

While descending to Manaus-Eduardo Gomes Airport following an uneventful flight from Tefé, the aircraft was correctly established on the ILS when the crew was instructed by ATC to initiate a go-around and to follow a holding pattern as the priority was given to an ambulance flight. The crew made a left turn heading 060° and continued the descent after passing 2,000 feet when the aircraft struck the ground and crashed about 33 km from the airport. The aircraft disintegrated on impact and all 33 occupants were killed.

Rico Linhas Aéreas - Rondonia Importaçao e Comercio

Following an uneventful flight from Tarauacá, the crew started the descent to Rio Branco-Presidente Médici Airport in limited visibility due to the night and rain falls. On final, the aircraft descended below the MDA and, at a speed of 130 knots, struck the ground and crashed in a field located 4 km short of runway 06. The aircraft was totally destroyed. Eight passengers were rescued while 23 other occupants were killed, among them the Brazilian politician Ildefonço Cardeiro.

Rico Linhas Aéreas - Rondonia Importaçao e Comercio

Following an uneventful flight from Humaitá, the crew completed the landing at Manaus-Eduardo Gomes Airport. After taxi, the crew was approaching the apron when he feathered the propellers and applied the brakes as they wanted to stop the aircraft. There was no deceleration despite both crew applied brakes. The copilot suggested to use reverse thrust but this was not possible as the propellers were already feathered. Out of control, the aircraft struck a brick building, damaging the left engine, and the right landing gear fell into a drainage ditch, approximately one meter deep. All 25 occupants evacuated safely while the aircraft was damaged beyond repair.

Ibertrans Aérea

The twin engine airplane departed Madrid-Barajas at 0635LT on a cargo service (flight IBT1278) to Bilbao, carrying one company mechanic, two pilots and a load of cargo consisting of 2,873 kilos of various goods. Following an uneventful flight, the crew was cleared to start the descent to Bilbao-Sondica Airport for an ILS approach to runway 30. During the descent, the crew encountered control problems which he attributed to an autopilot malfunction. While trying to identify the problem, the crew failed to realized that the rate of descent increased when the GPWS alarm sounded three times. Shortly later, while attempting to gain height, the aircraft struck the slope of Mt Santa Marina Vieja located 33 km from Bilbao Airport. The aircraft was destroyed by impact forces and all three occupants were killed. The wreckage was found near the village of Zaldíbar.

ACE Air Cargo

The captain and first officer were conducting a localizer DME back course approach to runway 36 in a twin-engine turboprop airplane during a night cargo flight under IFR conditions. The minimum visibility for the approach was one mile, and the minimum descent altitude (MDA) was 460 feet msl (338 feet agl). Prior to leaving their cruise altitude, the first officer listened to the ATIS information which included an altimeter setting of 29.30 inHg. No other altimeter information was received until the crew reported they were inbound on the approach. At that time, tower personnel told the crew that the visibility was one mile in light snow, the wind was from 040 degrees at 22 knots, and the altimeter setting was 29.22 inHg. The crew did not reset the airplane altimeters from 29.30 to 29.22. At the final approach fix (5 miles from the runway), the captain began a descent to the MDA. Thirty-six seconds before impact, the first officer cautioned the captain about the airplane's high airspeed. Due to strong crosswinds, the captain disconnected the autopilot 22 seconds before impact. He said he pushed the altitude hold feature on the flight director at the MDA. Eighteen seconds before impact, the airplane leveled off about 471 feet indicated altitude, but then descended again 9 seconds later. The descent continued until the airplane collided with the ground, 3.5 miles from the runway. The crew said that neither the airport, or the snow-covered terrain, was observed before impact. The crew reported that the landing lights were off. The airplane was not equipped with a ground proximity warning system.

Capital Taxi Aéreo

The twin engine aircraft was completing a cargo flight from Teresina to Fortaleza, carrying one passenger, two pilots and a load of 2,5 tons of medicines. On final approach to Fortaleza-Pinto Martins Airport, the aircraft was approaching at an excessive speed when flaps and landing gear were selected down. The aircraft became unstable and the captain who was the pilot-in-command continued the approach and the copilot did not intervene to correct the situation. On final, the thrust levers were positioned below the flight idle position, causing the aircraft to lose speed and to enter a right bank. It struck power cables and eventually crashed onto a house. The aircraft and the house were destroyed. The copilot was seriously injured while both other occupants and one people on the ground were killed. Seven other people on the ground were injured. Few hours later, the copilot died from his injuries.

Comair

The flight was being vectored for the approach to runway 3R at Detroit Metropolitan Wayne County Airport (DTW) when the aircraft descended and impacted the ground. The aircraft struck the ground in a steep nose-down attitude in a level field in a rural area about 19 nm southwest of DTW. The flight carried 26 passengers and 3 crew members. There were no survivors and the airplane was destroyed by impact forces and a post crash fire. Instrument meteorological conditions prevailed at the time of the accident. The investigation revealed that it was likely that the airplane gradually accumulated a thin, rough glaze/mixed ice coverage on the leading edge deicing boot surfaces, possibly with ice ridge formation on the leading edge upper surface, as the airplane descended from 7,000 feet mean sea level (msl) to 4,000 feet msl in icing conditions, which may have been imperceptible to the pilots. The pilots had been instructed by air traffic control to slow to 150 knots and according to flight data recorder information, the airplane began to show signs of departure from controlled flight as it decelerated from 155 to 156 knots while in a flaps-up configuration. The investigation disclosed that the FAA failed to adopt a systematic and proactive approach to the certification, and operational issues of turbopropeller-driven transport airplane icing. The icing certification process has been inadequate because it has not required manufacturers to demonstrate the airplane's flight handling and stall characteristics under a sufficiently realistic range of adverse ice accretion/flight handling conditions. The aircraft manufacturer had issued a revision in April, 1996 to the approved flight manual which included activation of the leading edge deicing boots at the first sign of ice formation. The airplane operator did not incorporate the procedure, because it was contrary to the company's trained procedures and practices and of the belief that enacting the changes would result in potentially unsafe operation. Investigators' discussion with management personnel at each of the seven U.S.-based operators of the aircraft indicated that at the time of the accident only two of these operators had changed their procedures to reflect the information in the revision. The FAA, at the time of the accident, did not require manufacturers of all turbine-engine driven airplanes to publish minimum airspeed information for various flap configurations and phases and conditions of flight. During Safety Board investigators postaccident interviews with company pilots, there were inconsistent answers on the complex and varied minimum airspeed requirements established by the company for both icing and nonicing conditions. It was also noted that the pilots uncertainty of the appropriate airspeeds might have been associated with the language used, the different airspeeds and criteria contained in the guidance, the company's methods of distribution, and the company's failure t o incorporate the guidance as a formal, permanent revision to the flight standards manual.

Atlantic Southeast Airlines - ASA

Atlantic Southeast Airline Flight 529 was climbing through 18,000 feet, when a blade from the left propeller separated. This resulted in distortion of the left engine nacelle, excessive drag, loss of wing lift, and reduced directional control. The degraded performance resulted in a forced landing. While landing, the airplane passed through trees, impacted the ground, and was further damaged by post impact fire. An exam of the left propeller revealed the blade had failed due to a fatigue crack that originated from multiple corrosion pits in the taper bore surface of the blade spar. The crack had propagated toward the outside of the blade and around both sides of the taper bore. Due to 2 previous blade failures (separations), a borescope inspection procedure had been developed by Hamilton Standard to inspect returned blades (that had rejectable ultrasonic indications) for evidence of cracks, pits and corrosion. The accident blade was one of 490 rejected blades that had been sent to Hamilton Standard for further evaluation and possible repair. Maintenance technicians, who inspected the blade, lacked proper NDI familiarization training and specific equipment to identify the corrosion that resulted in fatigue. The captain and seven passengers were killed.

Continental Express

In climb, captain (pic) increased pitch, when flight attendant (f/a) entered cockpit and suggested faster climb, so she could begin cabin service. Autoflight was set in pitch and heading modes, contrary to company policy. Pic and f/a had non- pertinent conversation for 4.5 min, while 1st officer (f/o) was making log entries. Airplane stalled in IMC at 17,400 feet. Initial recovery was at 6,700 feet after f/o lower gear, then due to improper recovery, 2nd stall occurred and recovery was at 5,500 feet. Left propeller shed 3 blades, left engine cowling separated, left engine was shut down in descent. Level flight could not be maintained and forced landing was made at closed airport. Pic overshot final turn due to controllability problems and landed fast with 1,880 feet of wet runway remaining. Airplane hydroplaned off runway and was further damaged. Crew got limited sleep during 3 day trip, though rest periods available. Freezing level near 11,500 feet, clouds tops to 21,000 feet with potential for icing to 19,000 feet. No pre-accident malfunction was found.

Continental Express

The airplane broke up in flight while descending from FL240. The horizontal stabilizer, or top of the T-type tail, had separated from the fuselage before ground impact. Examination revealed that the 47 screw fasteners that would have attached the upper surface of the leading edge assembly for the left side of the horizontal stabilizer were missing. They had been removed the night before during scheduled maintenance. Investigation revealed that there was a lack of compliance with the FAA-approved general maintenance manual procedures by the mechanics, inspectors, and supervisors responsible for assuring the airworthiness of the airplane the night before the accident. In addition, routine surveillance of the continental express maintenance department by the FAA was inadequate and did not detect deficiencies, such as those that led to this accident. All 14 occupants were killed.

Atlantic Southeast Airlines - ASA

Witnesses reported that the airplane suddenly turned or rolled left until the wings were perpendicular to the ground. The airplane then fell in a nose-down attitude. Examination of the left propeller components indicated a blade angle of about 3°, while the left propeller control unit (pcu) ballscrew position was consistent with a commanded blade angle of 79.2°. Extreme wear on the pcu quill spline teeth, which normally engaged the titanium-nitrided splines of the propeller transfer tube, was found. The titanium-nitrided surface was much harder and rougher than the nitrided surface of the quill. Therefore, the transfer tube splines acted like a file and caused abnormal wear of the gear teeth on the quill. Wear of the quill was not considered during the certification of the propeller system. The aircraft was totally destroyed upon impact and all 23 occupants were killed, among them John Goodwin Tower, Senator of Texas and the astronaut Manley Sonny Carter.

Brazilian Air Force - Força Aérea Brasileira

The crew was completing a local training flight at São José dos Campos Airport. While circling with one engine out, the pilot-in-command lost control of the airplane that crashed near the runway. Five occupants were killed and four others were injured.

Air Littoral

Following an uneventful flight from Brussels, the crew contacted Bordeaux Approach at 15:01 and was vectored for an ILS approach to runway 23. Visibility was poor with low clouds at 100 feet and a runway visual range (RVR) of between 650 and 350 metres. Flight 1919 crossed the KERAG beacon, the initial approach fix (IAF) at an altitude of FL144, at 15:04:40. Cloud base was still around 100 feet so the crew requested to enter a holding pattern to the south of the airport. The weather conditions slightly improved during the next few minutes and Bordeaux Approach reported a cloud base at 160 feet. Flight 1919 had not reached the holding pattern yet and the pilot decided to attempt to rejoin the ILS. At 15:06:38 the flight was cleared direct to the BD beacon and to descend down to 2000 feet. At the BD beacon, the flight was cleared for final approach and instructed to contact Bordeaux Tower. The airplane had overshot the centreline and was slightly right on the glidepath. Bordeaux Tower then instructed the flight to report over the Outer Marker, which was acknowledged by the captain. After crossing the Outer Marker, the airplane was still not properly established on the ILS. The airplane descended below the glideslope with the crew hurriedly deploying flaps and landing gear. The captain did not contact Bordeaux Tower as requested. Instead he took over control of the airplane, attempting to continue the approach. Both crew members had very little time to adapt to their new roles as the airplane was descending below the glide slope. The descent continued until the aircraft struck tree tops and crashed in the Eysines forrest, about 5 km short of runway. The aircraft was totally destroyed and all 16 occupants were killed.

Atlantic Southeast Airlines - ASA

Brand new, the aircraft was took over by ASA crew to be delivered to Atlanta, Georgia. He was cleared by the São José Tower controller to follow the 010° radial to the SJC VOR, and cross the VOR at 5,000 feet. Some time after takeoff São José Tower instructed the flight to climb to FL280 out of 5,000 feet and intercept the 352 radial of the SJC VOR. The flight crew failed to follow the instructions and continued at an altitude of 5,000 feet. In limited visibility due to low clouds, the airplane struck the slope of a mountain located in the Mantiqueira Mountain Range. The wreckage was found 700 feet below the summit. All five occupants were killed.
