Accident
A pilot was conducting a night ferry flight to deliver an aircraft to an operator based at Calcutta Airport. During cruise, the pilot encountered technical problems with the right engine and was forced to shut it down and feather its propeller. Shortly thereafter, the aircraft entered an uncontrolled descent. The aircraft broke up in the air at high speed and crashed in a field. The pilot, who was the sole occupant, was killed.
Investigation
The official investigation examined the accident and determined that the uncontrolled descent occurred for an undetermined reason. Reported factors included fire or explosion in flight, airframe failure in flight, the right engine being feathered but not secured, and high-speed breakup.
