Transall C-160

On 6 March 2008, a Transall C-160 aircraft, registered PK-VTQ, operated by PT. Manunggal Air, was on an unscheduled freight flight from Sentani Airport, Jayapura, to Wamena Airport, Papua. There were seven people on board; two pilots, two engineers, and three flight officers. The pilots reported that the approach and landing were normal. However, they told the investigators that both Beta lights did not illuminate during the landing roll, so they could not use reverse thrust. They reported that they used maximum brakes to slow the aircraft, and rolled through to the end of runway 15. During the 180-degree right turn at the end of the runway, they felt the left brakes grabbing, and had to use increased thrust on the left engine to assist the turn. After completing the turn, the pilots backtracked the aircraft towards taxiway “E”, about 450 meters from the departure end of runway 15. The air traffic controller informed the Transall crew that heavy smoke was coming from the left main wheels, and that they should proceed to taxiway “E” and stop on the taxiway. Before the aircraft entered taxiway “E”, the controller activated the crash alarm. The pilots stopped the aircraft on taxiway “E”, and the occupants disembarked and attempted to extinguish the wheel-bay fire with a hand held extinguisher. The airport rescue fire fighting service (RFFS) arrived at the aircraft 10 minutes after the aircraft came to a stop on taxiway “E”. It took a further 5 minutes to commence applying foam. The attempts to extinguish the fire were unsuccessful, and the fire destroyed the aircraft and its cargo of fuel in drums. Investigators found molten metal on the runway along the left wheel track for about 16 meters, about 100 meters from taxiway “E”, between taxiway “E” and the departure end of runway 15. There was also molten metal along the left wheel track on taxiway “E”.

After takeoff from Jayapura-Sentani Airport, while climbing, the crew informed ATC about engine problems and was cleared for an immediate return. Following a 180 turn, the crew initiated an approach to runway 30. After touchdown, the crew started the braking procedure and reduced the engine power when a technical problem occurred on the right engine. The aircraft went out of control, veered off runway to the left, collided with a drainage ditch and came to rest against palm trees located 72 metres to the left of the runway centerline and 1,050 metres from the runway threshold. 18 occupants were injured and a passenger was killed. The aircraft was written off.

The aircraft departed Jakarta-Halim Perdanakusuma Airport on a charter flight to Singapore, carrying expatriates who were leaving Indonesia due to political unrest. On approach to Singapore-Seletar Airport, the copilot followed the checklist but failed to arm the lift dumper which affected the antiskid system that could not be used. After landing on a wet runway surface, the crew started the braking procedure but this was insufficient so the captain applied emergency brakes which is not recommended when hydroplaning is suspected. Unable to stop within the remaining distance, the aircraft overran, lost its left wing and left main gear before coming to rest. All 80 occupants escaped uninjured while the aircraft was written off.
