Investigation Summary
The flight originated in Kuala Lumpur on the evening of June 21, 1982, arriving at Bombay during the peak of the monsoon season in the early hours of June 22. As the aircraft approached runway 27, the crew encountered poor visibility and heavy rain. Approximately 12 seconds before the first impact, the captain reduced engine power to minimum, which led to a rapid increase in the rate of descent due to altitude unawareness. The aircraft struck the ground 1,300 feet short of the runway, causing significant damage to the main wheel wells and tires. Following the hard landing, a wheel well fire warning sounded in the cockpit. The captain applied full power to initiate a go-around, and the aircraft briefly became airborne after rolling along the right edge of the runway. However, the speed bled off, triggering the stick shaker. The 707 stalled and impacted the ground near the end of the runway, breaking into three sections. Despite the severe structural failure and the presence of mud and water, no post-crash fire occurred. While official reports finalized the death toll at 17, early news reports from the scene initially claimed 19 fatalities.
Final Conclusions
The Indian Court of Inquiry determined the probable cause was the deliberate reduction of engine power by the pilot 12 seconds prior to first impact due to altitude unawareness. This resulted in a high rate of descent, a very heavy landing, and the aircraft undershooting the runway by 1,300 feet. Inclement weather was cited as a contributing factor.

Safety Actions & Advisories
Altitude Awareness and Power Management
The investigation highlighted the dangers of deliberate power reduction during low-visibility monsoon approaches without adequate altitude awareness. Recommendations focused on maintaining stabilized approach profiles and adhering to minimum power settings until the runway threshold is assured, especially in inclement weather.
