A technical failure that led to the loss of engine power caused an Army Cheetah helicopter to crash in the mountainous Tangtse area near Leh on May 20.
The two pilots and a third occupant, Major General Sachin Mehta, survived the crash with minor injuries.
A court of inquiry is likely to submit its final report within two months.
The Cheetah fleet has not been grounded and continues to undertake frontline duties in the Ladakh sector.
The crashed helicopter was a re-engined version of the Cheetah, and the cause of the accident is known, allowing the helicopters to continue flying after precautionary engine checks.
The latest crash has highlighted the need for swift replacement of the ageing Cheetah and Chetak fleets, which were designed six decades ago.
The army will begin phasing out its ageing fleets in a year or two and replace them with new light utility helicopters over the next eight to 10 years.
