What happened
During a ferry flight from Biak to the Netherlands, a seaplane was forced to divert to Abadan due to mechanical issues. Following a period of two weeks for repairs, the crew attempted to resume the journey toward Europe. However, shortly after departing from Abadan Airport, an oil leak was detected in the first engine, necessitating an immediate return to the airfield.
As the aircraft approached the airport, it became uncontrollable and impacted the ground near the runway. The impact resulted in a massive explosion. There were ten fatalities among the crew members on board.
Findings
Investigations into the accident focused on the malfunction of the engine's systems. It was determined that the thrust reversal system on engine number one was activated unintentionally, causing the aircraft to lose control during the approach.
