Aircraft

The aircraft involved was a Boeing 707-437 registered VT-DJJ and named Gauri Shankar after the mountain. It was the first jetliner inducted into the fleet of an Asian airline, manufactured by Boeing Commercial Airplanes in 1960 and powered by four Rolls-Royce Conway 508 engines.

Accident

On 21 June 1982, Flight 403 crashed after a botched go-around during a rainstorm. Out of 111 occupants on the aircraft, 2 of 12 crew members and 15 of 99 passengers were killed. One of the survivors was Raja Ramanna, an Indian nuclear physicist.

Investigation

An Indian public inquiry determined the probable cause of the accident to be "Deliberate reduction of engine power by the pilot 12 seconds prior to first impact due to altitude unawareness resulting in a high rate of descent, very heavy landing and the undershooting of the aircraft by 1300 feet."
