Circumstances:
The aircraft departed Jakarta Airport at 1009LT on a flight to Surabaya with intermediate stop at Bandung and Yogjakarta. The crew continued at 3,500 feet and received the permission to climb to 9,500 feet at 1043LT. At this time, the crew was requested to contact Bandung Tower. Five minutes later, while cruising at an altitude of 5,400 feet, the airplane struck the west slope of Mt Burangrang. The wreckage was found four days later and all 21 occupants were killed.
Probable cause:
The attempt by the pilot to fly over mountainous terrain when unsure of his position and in weather conditions which severely restricted visibility.

Circumstances:
About 13 minutes after takeoff from Palembang Airport, the crew reported the failure of the right engine and elected to return for a safe landing. In marginal weather conditions, the captain descended through the clouds with a rate of 300 feet per minute and after passing the last cloud layer, the aircraft banked right and crashed in a swampy area located 5 km short of runway threshold. A pilot was killed while the second crew was injured. The aircraft was destroyed.
Probable cause:
Failure of the right engine, a lack of precaution on the part of the captain and marginal weather. A contributing factor may have been the overloaded condition of the aircraft, however, not to such an extent that it forced the aircraft to descend to a dangerously low altitude.

Circumstances:
The crew departed Biak-Mokmer Airport at 0930LT for a local training flight. After he completed several touch and go, the captain requested the permission to modify the training program to perform other maneuvers. While performing a turn to the right off the Yapen coast, the airplane lost its right wing and crashed into the sea 13 km offshore and sank. The aircraft was lost and both pilots were killed.
Probable cause:
The Commission is of the opinion that, on the ground of the available evidence of the accident with the Twin Pioneer G-AOEO, the accident with the JZ-PPX has to be put down with to certainty nearing probability to the failure of the V-brace strut due to fatigue, because both aeroplanes were equipped with the same type of liftstrut and V-brace construction and because both aeroplanes were used in the same manner. The JZ-PPX carried out many instruction flights at a low altitude, many take-offs and landings, many manoeuvres with high flight loads, possibly up to the maximum loads. The G-AOEO also carried out many demonstration flights at a low altitude with man take-offs and landings, many manoeuvres, also with possibly maximum loads. The term of life of the V-brace as declared by the manufacturer, was based on conditions of flight which are not in agreement with the reality. During a meeting at September 6, 1957, Mr MacCallum of Scottish Aviation Ltd. gave a value of 4000hrs which raised a discussion. The Commission is aware of the fact that he cannot give a positive opinion upon the cause of the accident because there are no silent witnesses present, but nevertheless is of the opinion that there is a close conformity with the accident of the G-AOEO.

Circumstances:
The amphibian aircraft departed Jayapura-Sentani Airport along the north coast of New Guinea on a VFR flight plan for the Baliem River at 0840LT on a transport flight carrying a load of furniture, foodstuffs and aluminum sheets. At 0922 the Biak area control centre and Sentani aeronautical radio station both received a report from the aircraft that it was over the ldenburg River, course 220 degrees, VFR at 9,000 feet in slight rain, operation normal. When the next position report over the Baliem became overdue, the Sentani aeronautical radio station and the Biak area control centre attempted to contact the aircraft, but to no avail. The aircraft was found after one month of extensive searching, crashed on a 10,335 foot high mountain. The sole occupant, the pilot, did not survive the crash.
Probable cause:
The investigating authority reached the conclusion that the probable cause of the accident was the fact that the pilot was caught in adverse weather conditions during his attempt to reach better visibility conditions by climbing to a higher flight level and during this maneuver collided with a mountain,
