What happened
The incident occurred during the initial climb phase following departure from Abadan Airport. The flight was operating on behalf of the 1266th Army Air Force Base Unit, North African Division, Air Transport Command. Shortly after rotation, the aircraft experienced a sudden nose-down pitch attitude. This loss of control resulted in an immediate crash into the terrain. All four individuals on board were killed in the accident.
Findings
Investigations determined that the primary mechanical failure involved the right rudder tab. The component became stuck in a position that forced the aircraft's nose downward. The specific reason for this jamming mechanism was not identified in the available records.
