Circumstances:

Following a night takeoff from São Paulo-Guarulhos Airport, en route to Buenos Aires, the captain informed ATC about technical problems and was cleared to return for an emergency landing. The aircraft landed at a speed of 185 knots with flaps down to 15° on wet runway 09L. Unable to stop within the remaining distance, the aircraft overran, lost its undercarriage and came to rest 200 metres further. All 128 occupants were evacuated safely, among them two passengers were slightly injured. The aircraft was written off.

Probable cause:

It was determined that the n°3 leading edge flap actuator attachment fitting on the wing front spar had fractured due to corrosion. The actuator came away and caused the failure of some hydraulic lines and damage to the thrust control cables. Some 1981 Boeing Service Bulletins had not been complied with. One of these included the replacement of the aluminium leading edge flap actuator attachment fitting with a steel one; this had not been done. The following contributing factors were reported:
- Excessive workload on approach and landing due to the emergency situation,
- Poor approach planning,
- Lack of visibility due to the night,
- Poor crew coordination,
- Poor crew resources management,
- The crew forgot to lower the flaps electrically on approach, causing the speed to be 32 knots in excess,
- Poor aircraft maintenance and supervision,
- Failures in the supervision of the Company's operating sector.

While the DO228 was slightly damaged, the Y12 was written off. All 19 occupants escaped uninjured.

Probable cause:

It was determined that the loss of control occurred after the brakes failed because the pilot did not select the primary hydraulic system.

It bounced, landed 20 metres further then lost its right main gear and came to rest 225 metres further. all 10 occupants escaped uninjured while the aircraft was damaged beyond repair. The wreckage was still present at Cape Shmidt (N68.87953 W179.37426) by May 2013.

Probable cause:

Loss of control on short final after the pilot mistakenly put the engines on idle.

Circumstances:

During the takeoff roll from Sambailo Airport, at a speed of 180 km/h, the pilot-in-command realized he could not takeoff so he initiated an emergency braking procedure. As a distance of 350 metres was remaining, the aircraft was unable to stop within the distance, overran and came to rest. All 24 occupants escaped unhurt.

Probable cause:

It was determined that the crew failed to prepare the flight according to published procedures and failed to follow the pre-takeoff checklist. The aircraft was unable to gain sufficient speed because the parking brake was not fully released.

It overran, lost its undercarriage, struck a concrete wall and came to rest 870 past the runway end. All 10 occupants escaped uninjured while the aircraft was damaged beyond repair.

Probable cause:

Following a wrong manipulation, the flight engineer activated the thrust reversers on engine n°1 and n°3 but not on the engine n°2 that was providing full power. Such configuration reduced the braking action and the crew was unable to stop the aircraft within the landing distance available.

The crew decided to abandon the takeoff procedure and initiated an emergency braking procedure. Unable to stop within the remaining distance, the aircraft overran, rolled for about 500 metres then lost its nose gear and came to rest. All 117 occupants escaped uninjured while the aircraft was damaged beyond repair.

Probable cause:

It was determined that the crew failed to prepare the flight according to published procedures. The mass and balance sheet was incorrect. At the time of the accident, the total weight of the aircraft was six tons above MTOW and the CofG as too far forward.

Circumstances:

After liftoff from runway 30 at Krasnoyarsk-Iemilianovo Airport, while climbing at a speed of 165 km/h, the aircraft encountered difficulties to gain height. It collided with 25 metres tall trees located about 1,000 metres past the runway end, rolled to the right and crashed in a wooded area, some 450 metres to the right of the extended centerline. Both pilots and a passenger were killed.

Probable cause:

A two-fold decrease in the operating mode of the starboard engine during takeoff, caused by the actuation of the limiting system of the starboard engine and caused, most likely, with the achievement of MCR limit values, or with a failure that caused the system to be connected with the issuance of a false signal to reduce the speed of the gas generator. The activation of the system according to the MCR should have been preceded by its connection to work, which could have occurred as a result of an out-of-order connection of the limiter unit with the automatic protection circuit breakers AZRGK TSEBO turned off or when taking off with the AZRGK TSEBO turned on. The manifestation of a refusal in this flight could be facilitated by shortcomings in the activities of the ATB personnel of the Abakan aviation enterprise. Also, the decision of the crew to takeoff while the total weight of the aircraft was 280 kilos above MTOW.
