Incident Overview
On final approach to Calcutta-Dum Dum Airport, the right engine of the aircraft ceased operation. The copilot, who was designated as the pilot-in-command, lost control of the airplane. The aircraft stalled and impacted the ground short of the runway threshold. Both individuals aboard—the copilot and the captain—were uninjured. The aircraft was damaged beyond repair.
Sequence of Events
The accident occurred during the final approach phase. After the right engine stopped, the copilot, who was handling the controls, was unable to maintain control of the aircraft. The airplane stalled and crashed before reaching the runway. There was no fire, and the occupants emerged without injury.
Probable Cause
According to the official findings, the accident was attributed to the pilot's action of simulating a failure of the starboard engine during the final approach. This simulation was performed by feathering the propeller without the prior knowledge of the copilot, who was managing the aircraft. The copilot was unable to control the aircraft, which stalled and crashed. Additionally, the captain was not authorized to check the capability of the copilot.
