What happened
During a flight from Dhaka-Tejgaon Airport toward New Delhi, the crew encountered a critical mechanical failure approximately 40 minutes into the journey. A propeller component became detached from the engine, prompting the pilot to declare an emergency and divert the aircraft to Panagrah, West Bengal.
Following the separation of the propeller part, the flight crew experienced significant control issues, specifically finding that the landing gear and flaps could not be deployed. In an attempt to assess the situation or prepare for landing, the captain performed a very low-altitude pass, flying roughly one meter above the runway surface for a distance of two kilometers. During this maneuver, the right wing made contact with the ground. This impact caused the aircraft to lose stability and crash, subsequently resulting in a post-crash fire.
Findings
All 25 occupants on board the aircraft perished in the accident. The investigation determined that the primary factor leading to the emergency was the failure of propeller blades, which detached while the plane was in flight.
