1967 Demonstration Flight Crash at Malaybalay Airport (PK-PFB)

Background and Flight Operations On 24 April 1967, an aircraft arrived in Manila under a two-week lease from the Permina Oil Company of Indonesia to the Royal Netherlands Aircraft Factories - Fokker. The lease was for a series of demonstration flights in the Philippines. The aircraft conducted demonstration flights at various airports on 26 and 27 April 1967. On 27 April, the aircraft took off from Mactan at 0816 hours. After visiting ten different aerodromes, it arrived at Davao at 1557 hours, where its main fuel tanks and water/methanol tanks were filled to capacity. ## Accident Sequence At 1635 hours, the aircraft departed Davao and landed at Malaybalay Airport on runway 06 at 1705 hours. It continued its landing roll to the end of the runway, made a 180-degree turn, and took off from runway 24. Ground witnesses reported that the takeoff began with both engines at maximum power and that the aircraft became airborne at about two-thirds of the runway length. At that point, the right-hand propeller began to slow and stopped when the aircraft reached a height of about 1 metre above the ground. The aircraft had difficulty gaining altitude and followed a creek between two hills in a right-wing-low attitude. It struck a tree and some bamboos and crashed on a hill 45 metres higher than the runway elevation. The accident site was 1,380 metres from the end of runway 04 and 136.5 metres to the right of its extended centreline. The accident occurred at 1710 hours. ## Casualties All three crew members and 16 passengers were killed.
