Circumstances:
The single engine aircraft departed Kamonia on a special flight to Kamako on behalf of the United Nations Humanitarian Air Service (UNHAS), carrying three passengers and two pilots. During the takeoff roll from runway 34, the pilot-in-command started the rotation but the aircraft encountered difficulties to gain height. The nose gear and the cargo pod impacted an embankment located at the end of the runway and the aircraft flipped over and came to rest upside down. All five occupants escaped with minor injuries and the aircraft was destroyed.
Probable cause:
It was determined that the aircraft failed to gain sufficient speed during the last portion of the runway due to an excessive accumulation of sand on the ground. The pilot-in-command elected to rotate when the aircraft impacted terrain.
The two following factors were identified:
- The pilot's ability to make a timely decision,
- Lack of coordination between the two CRM (standard call out) pilots during takeoff manoeuvres.

Circumstances:
The pilot departed Manaus-Eduardo Gomes International Airport at 0940LT on a short positionning flight to Manaus-Aeroclub de Flores. On final approach to runway 11, the engine lost power and suffered power variations. The pilot attempted an emergency landing when the aircraft crashed 350 metres short of runway, bursting into flames. The pilot escaped with minor injuries and the aircraft was destroyed by a post crash fire.
Probable cause:
Contributing factors:
- Control skills - undetermined
The damage observed in the hot engine section components indicated the occurrence of an extrapolation of the ITT limits, which may have caused the melt observed in the blades of the compressor turbine. Thus, in view of the expected reactions of the engine during the use of the EPL, it is possible that there has been an inappropriate use of this resource and, consequently, an extrapolation of the engine limits, especially in relation to the temperature.
- Training - undetermined
The investigation of this accident identified issues related to the operation of the aircraft that could be related to the quality and/or frequency of emergency training with engine failure.
- Piloting judgment - undetermined
It is possible that the loss of lift produced by the flap retraction resulted in a sinking that prevented the plane from reaching the SWFN runway with the residual power that the engine still provided. In this case, an inadequate assessment of the effects of such action on the aircraft performance under those conditions would be characterized.
- Memory - undetermined
It is possible that the decisions made were the result of the pilot's difficulty in properly recalling the correct procedures for those circumstances, since these were actions to be memorized (memory items).
