Circumstances:
The aircraft, with only the pilot on board, was being flown from Archerfield to Caboolture via the light aircraft lane to the west of Brisbane in company with another aircraft. About five minutes after departing Archerfield, the pilot radioed that he was experiencing problems with both engines and that he was in an emergency situation. The pilot of the other aircraft advised him that there were suitable forced landing areas in and around a nearby golf course. However, the aircraft continued and slowly lost altitude before rolling inverted and diving steeply into the ground. Ground witnesses reported hearing loud backfiring and fluctuating engine RPM from the aircraft. These sounds were accompanied by erratic rolling and yawing of the aircraft before it rolled to the left and inverted. The right wing was severed outboard of the engine as the aircraft impacted a large tree before crashing onto a road.
Probable cause:
Wreckage examination revealed that the fuel selectors for both engines were set at the auxiliary tank positions, causing fuel for each engine to be drawn from the corresponding auxiliary tank in each wing. It was established that the aircraft had been refuelled to full main tanks prior to the flight. Further, the pilot had advised in a telephone conversation with an engineer before the flight that the contents of both auxiliary tanks was 60 litres or less. All fuel tanks except the left auxiliary tank were ruptured during the impact sequence. About one litre of fuel was recovered from this
tank. Examination of the aircraft engines indicated that the right engine was under power at impact while the left engine was not. The mechanical condition of the engines indicated that they were capable of normal operation.
The following factors are considered relevant to the development of the accident:
- The pilot did not use a written checklist.
- The pilot operated the aircraft with the auxiliary tanks selected when the fuel contents of these tanks was low.
- The pilot failed to conduct a forced landing.
Final Report:

Circumstances:
The pilot had a 25 minutes turnaround for the accident trip from the prior flight. No witnesses were found who observed the pilot preparing for the flight or performing a preflight inspection. Company procedures specify that the pilots are responsible for loading and unloading the baggage. The manifest for the prior flight showed 54 lbs of baggage in the nose compartment. Shortly after liftoff, the pilot told the local controller that the baggage door was open and he requested a 'go around.' The local controller told the pilot to make right traffic. Multiple witnesses saw the airplane in a nose high attitude during the initial climb after takeoff. They reported the pilot entered a right turn which continued until the airplane 'fell to the ground and hit nose first.' An airline pilot witness said that the airplane's actions were a 'classic VMC roll.' Other witnesses reported that the left nose baggage compartment door was open during the takeoff and initial climb. Evidence shows that the right eng was developing little or no power. All three occupants were killed.
Probable cause:
The pilot's failure to maintain adequate airspeed while maneuvering in the traffic pattern. A factor which contributed to the accident was the pilot's failure to assure that the nose baggage compartment door was secured.

Circumstances:
Shortly after takeoff from Eucott Bay, BC, while climbing to a height of about 300 feet, the pilot initiated a turn to the left to perform a 180 circuit to leave the valley, a standard procedure for the area. While turning, despite power was added and the aircraft was climbing, it descended to the left then stalled and crashed in a wooded area located 450 metres west of the point of departure, bursting into flames. All five occupants were killed.
Probable cause:
The exact cause of the accident could not be determined. However, the assumption that the loss of control was caused by downdrafts was not ruled out.

Circumstances:
The aircraft departed Pskov AFB on a local training flight, carrying three passengers, eight crew members and a load of ammunition. After takeoff, while in initial climb, the crew informed ATC that a fire erupted on board and was cleared to return for an emergency landing. The aircraft went out of control and crashed in a wooded area located 3,4 km from the airport and 480 metres to the left of the extended centerline, bursting into flames. The aircraft disintegrated on impact and all 11 occupants were killed.
Probable cause:
The exact cause of the fire on board could not be determined. However, it is believed that fire started in the cargo hold during the takeoff roll or maybe after rotation, probably in a box containing ammunition. Fire and explosion damaged elevator control systems, causing the aircraft to become uncontrollable.

Circumstances:
The aircraft was engaged in a local test flight, carrying nine engineers and pilots. Shortly after takeoff from Moscow-Zhukovsky Airport, while climbing to a height of 45 metres, the right propeller autofeathered. The aircraft started to roll left and right then reached a critical angle of attack. Out of control, it stalled and crashed 400 metres past the runway end, bursting into flames. Two people were seriously injured while seven others were killed. The aircraft was supposed to perform a series of five 7-minutes flights to test the noise from ground. At the time of the accident, the total weight of the aircraft was near the limit.
Probable cause:
It was determined that the right engine autofeathered immediately after lift-off due to an electronic malfunction.

Circumstances:
Aircraft was performing a routine administrative flight from Awsard to Agwanit with one UN Field Service generator technician, one Australian Signals Contingent doctor, one Swiss Medical Unit nurse and a Swiss Medical Unit pilot, all serving as members of MINURSO, the Mission of the UN in Western Sahara. On takeoff, pilot encountered an unspecified problem which caused the aircraft to roll to starboard and crash near the runway, the verges of which were heavily sown with landmines. Two of the four occupants were killed on impact and one died of injuries soon after. The Swiss nurse survived with critical injuries and was medevac first to Gran Canaria, then to Switzerland.
Probable cause:
The actual cause of the crash could not be determined but was blamed on an error by the dead pilot. Suspicion remained that the starboard wing had been struck by one of the violent downdrafts for which Awsard airfield was well known.

Circumstances:
Shortly after takeoff from La Paz-El Alto Airport, while in initial climb, the engine n°2 caught fire. The crew was unable to extinguish the fire and the captain shut down the engine and feathered its propeller. He maintained a low level then attempted an emergency landing in a wasteland located near Laja, about 18 km west of El Alto Airport. Following a 'normal' landing, the crew stopped the aircraft and evacuated the cabin. The fire spread to the left wing but was eventually contained.
Probable cause:
Fire on engine n°2 shortly after takeoff for unknown reasons.
