Circumstances:
Following a flight from El Nido Palawan, the crew of the Twin Otter landed at Manila-Ninoy Aquino Airport and was instructed to taxi via F1 to reach his parking place. At the same time, a Boeing 737-3Y0 operated by Philippine Airlines (flight PR1370 from Manila to Bacolod) was taking off from runway 13 so the crew of the Twin Otter was instructed to hold on taxiway F1. For unknown reasons, the crew misinterpreted this instruction and started to cross the runway when the Boeing 737 collided with the DHC-6 that was dragged for 130 metres. The Boeing was slightly damaged on its nose while the Twin Otter was destroyed. Both pilots were injured.
Probable cause:
Failure of the crew to follow ATC instruction, starting to cross the runway in use while a Boeing 737 was taking off at the same time.

The American pilot-in-command, American survey operator, and Peruvian Air Force observer are missing, and are presumed to be fatally injured. The flight originated from Bagua, Peru, at about 0617 mountain daylight time. Personnel from the Director General of Civil Aviation stated, the airplane departed from Bagua, Peru, conducting an aerial geological survey near the disputed boarder with Ecuador, in the Cenepa River area over dense Amazon jungle. The airplane did not return to Bagua, and there are no known recorded radio communications with N245GW. Search and rescue operations have been uneventful.

Circumstances:
Shortly after takeoff from Alotau Airport, while in initial climb, the aircraft caught fire and suffered an explosion. It entered an uncontrolled descent and crashed in shallow water about 2 km offshore. The aircraft was totally destroyed by impact forces and all 15 occupants were killed.
Probable cause:
An investigation conducted by the Australian Transport Safety Bureau (ATSB) revealed that an explosion and fire occurred shortly after takeoff, causing the electrical system to fail. The fire's source probably was the terminal board between the inverters and a control relay. Kerosene carried in passenger luggage in the Twin Otter's aft cargo hold possibly began leaking and was possibly ignited by faulty or age-deteriorated electrical wiring.

Circumstances:
On approach to Lagos-Murtala Muhammed Airport, the crew encountered poor weather conditions with heavy rain falls and strong winds. The copilot was in command and the airplane was too high on approach so the captain took over controls and steeped the approach. Nevertheless, the aircraft was still too high over runway 19L threshold when it encountered severe downdraft. It nosed down and struck the runway surface nose gear first. It bounced, veered off runway to the left, rolled to the apron and eventually collided with a parked Fokker F27 Friendship 200MP of the Nigerian Air Force registered NAF908. Both aircraft were destroyed and one of the pilot on board the Twin Otter was killed, all eight other occupants were injured.
Probable cause:
It was determined that the crew lost control of the airplane upon landing after the wind suddenly changed from 270° at 10 knots to 360° at 50 knots. Also, windshear was suspected.
