Circumstances:
At approximately 1310 hours PI-C55 took off from Ozamis City Airport for Pagadian on a scheduled flight with a pilot, nine passengers and two infants on board. Following a normal take-off and climb, the aircraft, at an altitude of 75 ft, was seen on a steep climb followed by a steep turn to the left. It then suddenly lost altitude, hit two trees and crashed in a nose-down attitude. Fire broke out immediately. The pilot and one passenger were killed, all 10 other occupants were injured.
Probable cause:
The probable cause of the accident was the uncontrollable stall at low altitude which resulted from the abrupt steep climb immediately after take-off. Contributing factors were:
- The improper loading of the aircraft,
- The prevailing gusty wind with a relatively high ambient temperature.

The crew (two pilots and one mechanic) was engaged in a post-maintenance check flight. Two minutes after takeoff from Goose Bay Airport, while climbing, the crew raised the flaps when the aircraft stalled. Simultaneously, the left wing broke out at its root. Out of control, the airplane dove into the ground and crashed, killing all three occupants. It was reported that ground maintenance was provided on the left port inner trailing edge flap.
Probable cause:
A sudden spontaneous full flap retraction caused the nose of the aircraft to drop. Loads on the wing exceeded the design strength, causing the left hand wing to break off. It struck the tail, causing the airplane to crash.
