Circumstances:

After landing at Buenos Aires-Aeroparque-Jorge Newbury Airport, the crew started the braking procedure and activated the reverse thrust that failed to deploy. The crew used the emergency brakes but the aircraft failed to stop within the remaining distance, overran and collided with a support vehicle (pick up) that was parked outside the safety zone. The aircraft lost its undercarriage and both wings and all four occupants were injured.

Probable cause:

The brakes and reverse thrust systems were unserviceable following a failure of the primary hydraulic system. The auxiliary braking system was also unserviceable. For unknown reasons, the problem has not been identified by the flying crew neither the maintenance personnel.

Circumstances:

The approach to Tijuana-General Abelardo L. Rodríguez Airport was completed in poor weather conditions with clouds down to 180 metres. On short final, the captain realized his position was not correct and made several correction but inefficiently. The aircraft landed hard, right main gear first. On impact, both tires on the right main gear burst. The aircraft went out of control, veered to right and came to rest. All six occupants escaped uninjured while the aircraft was damaged beyond repair.

Probable cause:

The crew completed a landing procedure following an unstabilized approach and failed to initiate a go-around.

Circumstances:

While maneuvering at low altitude to observe moose, the airplane stalled into the ground. The lodge's senior pilot stated that the lodge had no recurrent training program. Three passengers were killed while three other occupants including the pilot were seriously injured.

Probable cause:

The pilot's failure to maintain airspeed resulting in an inadvertent stall. A factor in the accident was the inadequate recurrent training of the pilot by the operator/management.

Circumstances:

The pilot reported the right engine failed, followed by the left engine approximately one minute later while he was in cruise at 25,000 feet. He said he initiated a steep descent to get below 18,000 feet, and attempts at restarting the left engine were unsuccessful. The pilot landed 500 feet down a 1,900 feet long runway and ran off the departure end, 300 feet, into a wooded area. Post accident investigation found 130 gallons of fuel onboard in the main tanks. The fuel was tested and found to be free of water. The fuel lines were free of obstructions and the fuel pumps worked. A failed torque sensor was found on the left engine which would disconnect the left engine driven fuel pump. The right engine was test run satisfactorily.

Probable cause:

Improper emergency procedures by the pilot which resulted in the shutdown of an operative engine, following a power loss due to a failed torque sensor in the other engine, which resulted in a total power loss approach, landing, and overrun.

Circumstances:

The crew was completing a cargo service from Khmelnytskyi to Samara with an intermediate stop in Donetsk. The approach was completed by night and limited visibility due to thunderstorm activity and heavy rain falls. On final, the crew failed to realize the aircraft was not properly aligned and continued the approach when the aircraft landed hard 80 metres to the left of the runway. Out of control, it rolled for few dozen metres and eventually collided with a building. The aircraft was destroyed and all five occupants were seriously injured.

Probable cause:

Poor approach planning and landing configuration on part of the crew. The aircraft was not properly aligned and its rate of descent was excessive during the last segment. This led the aircraft to land with a positive acceleration of 5,8 g.

Aircraft flight cycles:

Circumstances:

The twin engine aircraft was engaged in a local skydiving mission, carrying 17 skydivers and two pilots. After takeoff, while climbing, both engines simultaneously suffered a total power loss. The commander reported that the simultaneous failure did not induce any yaw and that the only two warning lights which illuminated in the cockpit were those indicative of double engine failure. Following the power loss, the aircraft's speed decayed rapidly leading the commander to suspect that the automatic outboard wing spoilers had also deployed. Realising that a forced landing was the only option available to him, he initiated a steep descent to maintain airspeed and a turn through 90° to the right to position the aircraft for a forced landing in a large field of corn stubble. The aircraft landed heavily in a slightly nose up attitude, banked slightly to the right, at an estimated speed of 170 km/h (92 knots) and slid to rest with substantial damage to the fuselage, landing gear, wing struts, propellers and wings. All 19 occupants evacuated the cabin and were uninjured.

Probable cause:

The following findings were reported:
- A latent defect in the electrical system caused a simultaneous total power loss as the flaps were retracted at 500 feet agl on climb out, with automatic operation of both asymmetric spoiler systems.
- The latent defect had been caused by progressive loosening of a single earthing screw, which provided a common earth point for the flap electric signalling and propeller auto feathering systems. This induced a high resistance to earth at this point and caused feathering of both propellers when flap retraction was selected, in addition to automatic closure of both engine fuel shut-off valves (within the fuel control units) and extension of both outboard spoilers.
- At manufacture in Poland a single earthing point had been installed which was not in accordance with the design requirements for this aircraft type as issued by the Antonov Design Bureau, which had required dual combined earthing terminals for the flap signalling and propeller auto feathering systems.
- The Antonov Design Bureau had never cleared this type of aircraft for flight with the aft clam-shell doors removed, or for parachute training.
- This aircraft had been incorrectly granted an Aerial Work Permit for parachuting operations in the UK by the Department of Transport, assisted by the CAA, as a result of implicit reliance upon submitted documentation which was subsequently proven invalid.

Circumstances:

During takeoff roll at Khorugh Airport, at Vr speed, the crew started the rotation but the aircraft failed to respond and did not lift off. It continued at high speed, overran, collided with a concrete wall located 150 metres past the runway end and eventually crashed in the Pyanj River. Four passengers were rescued while 82 other occupants were killed, most of them woman, children and soldiers.

Probable cause:

The accident occurred during the Tajik Civil War. It was determined that soldiers forced the crew to embark as many passengers as possible while the Yak-40 is certified fox max 32 passengers. At the time of the accident were 81 passengers on board. As the total weight of the aircraft was 3 tons above MTOW, it was impossible to take off in such conditions.
