On final approach to Leh, the pilot reported technical problems when the airplane lost height, struck a house and crashed in a huge explosion less than 2 km short of runway threshold. The aircraft disintegrated on impact and all 77 occupants were killed as well as one people on the house.
It is believed that an asymmetric flaps occurred on final approach, causing the aircraft to get inverted and crash. When flaps were selected down, only the flaps on left wing moved down while the flaps on right wing remained blocked in an inappropriate angle.
