Incident
The accident occurred during the descent phase of a flight bound for Calcutta-Dum Dum Airport. As the aircraft approached the border between India and Bangladesh, the crew encountered poor weather conditions associated with thunderstorm activity. The crew lost control of the airplane, which subsequently crashed in an open field near Khulna, Bangladesh, approximately 55 kilometers southeast of the intended airport. The impact was catastrophic, destroying the airplane and killing all 44 occupants, including both crew and passengers.
Probable Cause
The official investigation determined that the probable cause was loss of control caused by turbulence and severe downdrafts encountered while flying in thunderstorm activity.
