Lockheed C-130 Hercules

On 8 June 2020, at approximately 2205 hours local time (L), the mishap aircraft (MA), a C-130H (tail number (T/N) 94-6706), was involved in a mishap during a routine mobility airlift mission from Ali Al Salem Air Base, Kuwait, into Al Taji (Camp Taji), Iraq, when it failed to come to a stop during landing, overran the runway, and impacted a concrete barrier. All 26 mishap crew (MC) members and passengers survived the mishap, with relatively minor injuries to two of the individuals. The MA was damaged beyond repair, and was valued at $35,900,000. The MA was from the 165th Airlift Wing (165 AW), Georgia Air National Guard (ANG), was manned with Wyoming ANG crew members deployed from the 153d Airlift Wing (153 AW), in Cheyenne, Wyoming, and assigned to the 386th Air Expeditionary Wing (386 AEW) at Ali Al Salem Air Base, Kuwait. The mishap occurred at the end of the first planned leg of the MC’s mission on 8 June 2020. The MC departed Ali Al Salem Air Base, Kuwait, at approximately 2053L, with an uneventful start, taxi, takeoff, and cruise to Camp Taji. During descent into Camp Taji, the MC prepared the MA for a nighttime landing, using night vision devices. During this time, the MC turned the MA earlier than their planned turn point, did not descend to lower altitudes in accordance with their planned descent, and allowed the airspeed to exceed recommended maximum speeds for the configuration the plane was in. During the landing, the MA continued to be above the planned glideslope and maintained excessive airspeed, with a nose-down attitude until touchdown. The MA proceeded to “porpoise” or oscillate down the runway from the point of touchdown until the MA was slowed sufficiently by use of reverse thrust from the engines to allow the MA to settle onto the wheels, which in turn allowed for the brakes to engage. The MA, despite slowing somewhat, had less than 1,000 feet of runway remaining by that point, and thus overran the runway and did not come to a complete stop until it impacted a 12-foot-high concrete barrier, approximately 600 feet past the runway.

On 27 January 2020, at approximately 1309 hours local time (L), an E-11A, tail number (T/N) 11-9358, was destroyed after touching down in a field in Ghanzi Province, Afghanistan (AFG) following a catastrophic left engine failure. The mishap crew (MC) were deployed and assigned to the 430th Expeditionary Electronic Combat Squadron (EECS), Kandahar Airfield (KAF), AFG. The MC consisted of mishap pilot 1 (MP1) and mishap pilot 2 (MP2). The mission was both a Mission Qualification Training – 3 (MQT-3) sortie for MP2 and a combat sortie for the MC, flown in support of Operation FREEDOM’S SENTINEL. MP1 and MP2 were fatally injured as a result of the accident, and the Mishap Aircraft (MA) was destroyed. At 1105L, the MA departed KAF. The mission proceeded uneventfully until the left engine catastrophically failed one hour and 45 minutes into the flight (1250:52L). Specifically, a fan blade broke free causing the left engine to shutdown. The MC improperly assessed that the operable right engine had failed and initiated shutdown of the right engine leading to a dual engine out emergency. Subsequently, the MC attempted to fly the MA back to KAF, approximately 230 nautical miles (NM) away. Unfortunately, the MC were unable to get either engine airstarted to provide any usable thrust. This resulted in the MA unable to glide the distance remaining to KAF. With few options remaining, the MC maneuvered the MA towards Forward Operating Base (FOB) Sharana, but did not have the altitude and airspeed to glide the remaining distance. The MC unsuccessfully attempted landing in a field approximately 21 NM short of FOB Sharana.

Lockheed C-130 Hercules

On 2 May 2018, at approximately 1127 hours local time (L), the Mishap Aircraft (MA), a WC-130H, tail number 65-0968, assigned to the Puerto Rico Air National Guard, 156th Airlift Wing (156 AW), located at Muñiz Air National Guard Base, Puerto Rico, crashed approximately 1.5 miles northeast of Savannah/Hilton Head International Airport (KSAV), Georgia. All nine members aboard the MA—Mishap Pilot 1 (MP1), Mishap Pilot 2, Mishap Navigator, Mishap Flight Engineer, and Mishap Loadmaster (collectively the “Mishap Crew (MC)”), and four mission essential personnel, Mishap Airman 1, 2, 3, and 4—perished during the accident. The MC’s mission was to fly the MA to the 309th Aerospace Maintenance and Regeneration Group at Davis-Monthan Air Force Base, Arizona (commonly referred to as the “Boneyard”), for removal from service. The MA had been at KSAV for almost a month, since 9 April 2018, to undergo prescheduled fuel cell maintenance and unscheduled work on engine number one by 156 AW maintenance personnel using the facilities of the 165th Airlift Wing. During takeoff roll, engine one revolutions per minute (RPM) fluctuated and did not provide normal RPM when MP1 advanced the throttle lever into the flight range for takeoff. Approximately eight seconds prior to aircraft rotation, engine one RPM and torque significantly decayed, which substantially lowered thrust. The fluctuation on roll and significant performance decay went unrecognized by the MC until rotation, when MP1 commented on aircraft control challenges and the MA veered left and nearly departed the runway into the grass before it achieved flight. The MA departed KSAV at approximately 1125L. As the MC retracted the landing gear, they identified the engine one RPM and torque malfunction and MP1 called for engine shutdown. However, the MC failed to complete the Takeoff Continued After Engine Failure procedure, the Engine Shutdown procedure, and the After Takeoff checklist as directed by the Flight Manual, and the MA’s flaps remained at 50 percent. Additionally, MP1 banked left into the inoperative engine, continued to climb, and varied left and right rudder inputs. At an altitude of approximately 900 feet mean sea level and 131 knots indicated air speed, MP1 input over nine degrees of left rudder, the MA skidded left, the left wing stalled, and the MA departed controlled flight and impacted the terrain on Georgia State Highway 21.

Pilatus PC-12

On 14 Mar 17, at 1835 local time (L), a U-28A, tail number 0724, crashed one-quarter mile south of Clovis Municipal Airport (KCVN), New Mexico (NM). This aircraft was operated by the 318th Special Operations Squadron, 27th Special Operations Wing, Cannon Air Force Base (AFB), NM. The aircraft was destroyed and all three crewmembers died upon impact. The Mishap Aircraft (MA) departed Cannon AFB at 1512L for tactical training over Lubbock, Texas, followed by pilot proficiency training at KCVN. The Mishap Crew (MC) entered Lubbock airspace at 1545L, completed their tactical training, and departed Lubbock airspace at 1735L enroute to KCVN. The MC entered the KCVN traffic pattern at 1806L, where they conducted multiple approaches and landings prior to executing the mishap maneuver, a practice turnback Emergency Landing Pattern (ELP). The MC entered the practice turnback ELP with 0° flaps led to increased aircraft nose-down attitudes and higher descent rates required to maintain a safe angle of attack versus a comparative 15° flap approach. In addition, 0° flap stall speeds are higher than 15° flap stall speeds – 15 to 25 knots higher for the range of bank angles flown by the MC during the practice turnback ELP. The MC was also late to achieve the bank angle required to enable the MA to align with the extended centerline for the runway resulting in an overshoot condition. The MC attempted to arrest their excessive nose-down attitude, descent rate, and shallow bank angle by pulling back on the aircraft yoke and increasing bank angle. The g-load from the MC pull back, coupled with the MA's increased bank angle, slowed the MA airspeed below 0° flap stall speed and it departed controlled flight. Subsequent power increase and flight control inputs would not have enabled the aircraft to recover from the stall within remaining altitude. After entering the stall, the MC increased power; however, it was not enough to overcome the MA descent rate. At no point during the practice turnback ELP did the MA performance reflect a MC intent to abort the maneuver. The MA impacted the ground with a 13° nose-high, 7° left-wing low attitude. The aircraft was destroyed upon impact and all three occupants were killed. Crew: Cpt Andrew Becker, pilot, 1st Lt Frederick Dellecker, copilot, Cpt Kenneth Dalga, combat systems officer.

Boeing B-52 Stratofortress

On 19 May 2016, at 0832 hours local time (L), a B-52H, tail number 60-0047 [Mishap Aircraft (MA)], assigned to the 69th Expeditionary Bomb Squadron, 5th Bomb Wing, Andersen Air Force Base, Guam, departed the prepared-surface overrun of Runway 06 Left (RWY 06L) during a highspeed, heavy-weight, aborted takeoff. The Mishap Crew (MC), which consisted of the Mishap Pilot (MP), Mishap Co-Pilot (MCP), Mishap Radar Navigator (MRN), Mishap Navigator (MN), Mishap Electronic Warfare Officer (MEW), an augment pilot occupying the Mishap Gunner (MG) station, and an Instructor Weapon System Officer occupying the Mishap Instructor Pilot (MIP) jump seat, were conducting a Higher Headquarters Directed mission. The MC were treated for minor injuries consistent with a ground egress. The MA sustained total damage with a loss valued at $112M. There was no damage to private property. The MC were cleared for takeoff at 0831L. The MA accelerated within performance standards verified by takeoff and landing data calculated performance for S1 timing and S1 decision speed. Approximately three to five seconds after reaching the S1 speed of 111 knots, the MP, MCP, and MN observed birds in front of the MA at wing level. Shortly thereafter, the MP and MCP observed engine indications for numbers 5, 6, and 7 “quickly spooling back” from the required takeoff setting. The MP also observed high oil pressure indications on the number 8 engine and a noticeable left-to-right yawing motion. Accelerating through approximately 142 knots, the MP simultaneously announced and initiated aborted takeoff emergency procedures. With the throttles set to idle thrust and airbrakes set to six, the MP initiated continuous braking pressure. The MCP deployed the drag chute at 135 knots. The drag chute failed to inflate properly. At 2,500 feet runway remaining, the MP shut off the outboard engines (numbers 1/2 and 7/8). Shortly thereafter, the MP announced the MA and MC were going to depart the prepared surface. The MEW jettisoned the defensive compartment, starboard-side hatch and the MP shut off the inboard engines (numbers 3/4 and 5/6). The MA departed the prepared surface shearing the main landing gear. The MA finally came to a rest slightly canted from runway centerline, right wing down approximately 300 feet from the runway, and subsequently caught on fire. The MC performed emergency aircraft shutdown procedures and safely egressed the MA through the MEW hatch.

Lockheed C-130 Hercules

On 2 October 2015, at approximately 0016LT, the airplane crashed after takeoff from runway 31 at Jalalabad Airfield, on the second scheduled leg of a contingency airlift mission. The mishap aircraft was assigned to the 455th Air Expeditionary Wing at Bagram Airfield, Afghanistan. The mishap crew (MC) was from the 774th Expeditionary Airlift Squadron. The MC consisted of the mishap pilot (MP), the mishap copilot (MCP), and two mishap loadmasters. Also on board were two fly-away security team (FAST) members and five contractors travelling as passengers. Upon impact, all eleven individuals onboard the aircraft died instantly. The aircraft struck a guard tower manned by three Afghan Special Reaction Force (ASRF) members, whom also died. The MA and cargo load were destroyed, and a perimeter wall and guard tower were damaged.

Lockheed C-130 Hercules

On 19 May 2013, at approximately 0950 Zulu (1420 local), a C-130J, tail number (T/N) 04-3144, assigned to the 41st Airlift Squadron, 19th Airlift Wing, Little Rock Air Force Base (AFB), Arkansas, ran off the end of a runway at Forward Operating Base (FOB) Shank, Northeast, Afghanistan, struck a ditch which collapsed the nose gear and eventually ripped the right main landing gear from the fuselage. The right outboard engine struck the ground, pressurized fuel and oil lines were broken, fluid was sprayed over the cracked engine casing, and the right wing caught fire. The mishap aircraft (MA) came to a full stop at approximately 544 feet (ft) off the end of the paved runway surface. The mishap crew (MC), Aeromedical Evacuation (AE) crew and two ambulatory patients safely evacuated the aircraft through the top flight-deck emergency escape hatch meeting 600 ft off the nose of the aircraft. There were no fatalities, significant injuries or damage to civilian property. The total estimated loss is $73,990,265. The MA was on an AE mission and included five active duty C-130J crewmembers from the 772nd Expeditionary Airlift Squadron (19th Airlift Wing deployed), Kandahar Air Base (AB), Afghanistan. Additionally, the MA had aboard six reserve AE crewmembers from the 651st Expeditionary Aeromedical Evacuation Squadron (349th Air Mobility Wing and 433rd Airlift Wing deployed), Kandahar AB, Afghanistan. The mishap sortie happened on the third of five planned legs that day to an airfield that was at 6,809 ft Mean Sea Level (MSL) and experiencing winds varying from 200 to 250 degrees gusting from 6 to 28 knots. On the second attempted landing, the MA touched down approximately 1,500 ft down the runway but was 27 knots indicated airspeed (KIAS) faster than computed touchdown landing speed leading to the aircraft going off the end of the runway at approximately 49 KIAS.

Boeing KC-135 Stratotanker

On 3 May 2013, at approximately 1448 hours local time (L), a KC-135R, tail number 63-8877, assigned to the 22d Expeditionary Air Refueling Squadron, 376th Air Expeditionary Wing, Transit Center at Manas, Kyrgyz Republic, crashed in the foothills of mountains located 6 miles south of Chaldovar, Kyrgyz Republic. The mishap crew (MC), which consisted of the mishap pilot (MP), mishap co-pilot (MCP), and mishap boom operator (MBO), perished during the accident. The mishap aircraft (MA) exploded inflight, impacted the terrain at three main locations, and burned. The MA was completely destroyed with total loss to government property estimated at $66.3 million. Upon impact, approximately 228 cubic meters of soil were contaminated with jet fuel, and three distinct craters containing a burn pattern were created. The MA’s mission was to refuel coalition aircraft in Afghanistan and then return to the Transit Center at Manas. Immediately after takeoff, the MA experienced an unexpected rapid heading change from the direction of flight known as a crab. During climb, nearly continuous rudder hunting caused the MA’s nose to hunt slowly left and right about one degree in both directions. The MP commented on the lateral control challenges and possible series yaw damper (SYD) malfunction but continued the mission without turning off either the SYD or rudder power. Approximately nine minutes into the flight, the MA began a series of increasing yaw and roll oscillations known as a dutch roll, which was undiagnosed by the MC. The MCP attempted to decrease these oscillations using manual aileron controls, as well as two brief attempts with the autopilot. The manual corrective inputs kept the oscillations from growing. The autopilot use further exacerbated the situation, and the oscillations intensified. After the second autopilot use, the MP assumed control of the MA and used left rudder to start a left turn. A subsequent series of alternating small rudder inputs, caused by the MA’s dutch roll-induced acceleration forces varying the MP’s foot pressure on the rudder pedals, sharply increased the dutch roll oscillations. Within 30 seconds, the MP made a right rudder input to roll out of the turn, exacerbating the dutch roll condition. The cumulative effects of the malfunctioning SYD, coupled with autopilot use and rudder movements during the unrecognized dutch roll, generated dutch roll forces that exceeded the MA’s design structural limits. The tail section failed and separated from the aircraft, causing the MA to pitch down sharply, enter into a high-speed dive, explode inflight and subsequently impact the ground at approximately 1448L. Crew: Cpt Victoria Ann Pinckney, Cpt Mark Tyler Voss, T/Sgt Herman Mackey III.

Beechcraft MC-12W Liberty

On 27 April 2013, at approximately 1243 local time (L) in Afghanistan, an MC-12W, tail number 09-0676 impacted terrain 110 nautical miles northeast of Kandahar Airfield (KAF) while on a combat intelligence, surveillance, and reconnaissance (ISR) mission. The four crewmembers on board were the Mishap Mission Commander (MMC), Mishap Pilot (MP), Mishap Sensor Operator (MSO), and Mishap Tactical Systems Operator (MTSO). The four airmen were killed instantly on impact and the Mishap Aircraft (MA), valued at $19.8 million, was destroyed. The crew and MA were deployed to the 361st expeditionary Reconnaissance Squadron, 451st Air Expeditionary Wing, KAF, Afghanistan. The MA, callsign Independence 08, departed KAF at 1157L and entered orbit at 1229L. The MA encountered deteriorating weather in the orbit and was climbing from 20,000 to 23,000 feet mean sea level (MSL) at 1241L to fly above the weather when the mishap occurred. In addition, the crew had found an enemy combatant and was in the process of adjusting their orbit to enhance mission success.

Lockheed C-130 Hercules

On 1 July 2012, at approximately 1738 Local time, a C-130H3, Tail Number 93-1458, assigned to the 145th Airlift Wing, North Carolina Air National Guard, Charlotte Douglas International Airport (KCLT), Charlotte, North Carolina, crashed on public land managed by the United States Forest Service (USFS), while conducting wildland firefighting operations near Edgemont, South Dakota. At the time of the mishap all members of the Mishap Crew (MC) were assigned or attached to the 156th Airlift Squadron, based at KCLT. The Mishap Crew (MC) consisted of Mishap Pilot 1 (MP1), Mishap Pilot 2 (MP2), Mishap Navigator (MN), Mishap Flight Engineer (ME), Mishap Loadmaster 1 (ML1) and Mishap Loadmaster 2 (ML2). For the mishap sortie, MP1 was the aircraft commander and pilot flying in the left seat. MP2 was in the right seat as the instructor pilot. MN occupied the navigator station on the right side of the flight deck behind MP2. ME was seated in the flight engineer seat located between MP1 and MP2, immediately aft of the center flight console. ML1 and ML2 were seated on the Modular Airborne Fire Fighting System (MAFFS) unit, near the right paratroop door. ML1 occupied the aft MAFFS control station seat and ML2 occupied the forward MAFFS observer station seat. MP1, MP2, MN and ME died in the mishap. ML1 and ML2 survived the mishap, but suffered significant injuries. The mishap aircraft (MA) and a USFS-owned MAFFS unit were destroyed. The monetary loss is valued at $43,453,295, which includes an estimated $150,000 in post aircraft removal and site environmental cleanup costs. There were no additional fatalities, injuries or damage to other government or civilian property.
