The Super Constellation, named "Neutron", departed from Biak runway 10 at 03:32 at night for the first leg of a flight back to Amsterdam. Shortly after takeoff the pilot asked the tower controller to keep the runway lights on and requested permission for a low run over the airfield. Both requests were granted. The aircraft was in a 180deg turn when it lost altitude gradually until it struck the sea and broke apart. The wreckage sank in 250 m of water.

Probable Cause:

PROBABLE CAUSE: "The explanation of the accident lies either in an error on the part of the pilot or in a technical failure. The Board was unable to state whether the accident could have been caused by a combination of both pilot error and technical failure. The Board was of the opinion that low runs should not be made by aircraft on scheduled services. The magnitude of the danger that is inherent in the proximity of the ground on takeoff and landing should not be increased unnecessarily by flying at low altitude."
