An aircraft experienced right engine technical problems while approaching Dhaka-Tejgaon Airport, leading to an emergency landing in an open field. All seven occupants escaped uninjured; the aircraft was damaged beyond repair.

Incident Details

While approaching Dhaka-Tejgaon Airport at an altitude of 4,000 feet, the flight crew encountered technical issues with the right engine. The crew shut down the engine, but a few seconds later managed to restart it. However, as the turbine temperature increased, the engine was shut down again. During this second shutdown, the crew was unable to feather the propeller.

Emergency Landing

The inability to feather the propeller resulted in excessive aerodynamic drag, causing the aircraft to lose altitude. The captain then attempted an emergency landing in an open field. Upon touchdown, the aircraft's undercarriage collapsed, and the aircraft came to rest.

Aftermath

All seven occupants evacuated the aircraft without injury. The aircraft itself sustained damage beyond repair.

Probable Cause

According to the official investigation, the probable cause was a failure of the right engine for unknown reasons. Additionally, the failure of the automatic propeller pitch control mechanism was identified as a contributing factor.
