What happened
The incident occurred shortly after the aircraft departed Hmwabi Airbase. During the initial climb phase of the flight, the machine encountered a cumulonimbus cloud formation. Upon entering this weather system, the aircraft lost aerodynamic control and subsequently crashed into an adjacent field. The impact was fatal for everyone on board. There were 41 occupants in total at the time of the accident. Among them were 37 wounded soldiers who had been transferred home following their release by Japanese forces. The remaining personnel comprised the flight crew, identified as members of 117 Squadron, and other military staff.
Findings
The primary contributing factor to the loss of control was the aircraft's entry into severe convective weather while still in the climb phase. The source material does not provide a formal investigation report or specific mechanical failure details, but the sequence indicates that the interaction with the cumulonimbus cloud directly led to the uncontrollable descent and subsequent impact.
