Accident Sequence
The aircraft was engaged in a local flight with 17 passengers and a crew of four. After takeoff from Cocos Island Airport, the crew climbed to 5,000 feet then reduced altitude for a low pass over the airport. Approaching the airport at a speed of 380 knots and at a height of about 300 feet, the pilot-in-command increased engine power in an attempt to gain height. During this maneuver, the aircraft lost several pieces from the left wing.
Emergency Landing
Due to severe vibrations and problems of controllability, the crew decided to attempt an emergency landing near the airport. The aircraft struck the ground, lost its undercarriage, and came to rest in shallow water.
Casualties and Damage
A passenger was killed after being hit by propeller blades that punctured the fuselage. All 20 other occupants escaped uninjured. The aircraft was damaged beyond repair.
Probable Cause
The official probable cause is a forced landing following severe vibrations after several elements from the left leading edge detached in flight.
