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.
Probable cause:
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.

Circumstances:
The four engine aircraft departed Chandigarh on a flight to Leh, carrying 98 passengers, soldiers and family members. While descending to Leh, the crew encountered poor weather conditions with snowstorm and the captain made a 180 turn to return to Chandigarh as a landing at Leh Airport was impossible. Few minutes later, while cruising in zero visibility at an altitude of 22,000 feet, the airplane struck the slope of a snow covered mountain located near the Rohtang Pass, Himachal Pradesh. As the airplane failed to return to Chandigarh, SAR operations were conducted but eventually suspended few weeks later as no trace of the aircraft no the 102 occupants was found. Some debris were found in August 2003 at an altitude of 5,400 meters in the Dhaka Glacier and three bodies in August 2007.
