Causes
The main cause of the accident was the unexpected poor performance of the aircraft after losing one engine, which necessitated an emergency landing in a very unsuitable place. This poor performance may have been contributed by the fact that the propeller of the non-functioning engine was not feathered as required for one engine-out operation as per the approved flight manual. It is also alternatively possible that the pilot having minimum experience on this type of aeroplane, became overcautious and opted for an immediate landing rather than flying back to a suitable airstrip only five minutes away.
However, it is considered that the pilots' judgement to undertake the flight without considering the visual verification of available fuel was poor airmanship.
