The court of inquiry into the December 2021 helicopter crash — in which Chief of Defence Staff General Bipin Rawat and 13 other people were killed — has ruled out mechanical failure, sabotage or negligence in the incident, the Indian Air Force said in a statement on Friday, January 14. The tri-services court of inquiry, led by Air Marshal Manavendra Singh, that investigated the helicopter crash has found that it was an accident, and was “a result of entry into clouds due to unexpected change in weather conditions in the valley.” India's first Chief of Defence Staff General Bipin Rawat, his wife and 12 other armed forces personnel, were killed in the helicopter crash at Coonoor in Tamil Nadu on December 8.
“The Tri-Services Court of Inquiry into the Mi-17 V5 accident on 08 Dec 21 has submitted its preliminary findings. The inquiry team analysed the Flight Data Recorder and Cockpit Voice Recorder besides questioning all available witnesses to determine the most probable cause of the accident. The Court of Inquiry has ruled out mechanical failure, sabotage or negligence as a cause of the accident,” the statement by the IAF read.
“The accident was a result of entry into clouds due to unexpected change in weather conditions in the valley. This led to spatial disorientation of the pilot resulting in Controlled Flight into Terrain. Based on its findings, the Court of Inquiry has made certain recommendations which are being reviewed,” the IAF statement added. According to US aviation regulator FAA, CFIT is defined as an unintentional collision with terrain — the ground, a mountain, a body of water, or an obstacle — while an aircraft is under positive control.
The CDS and his wife were among the 13 people declared dead in the crash. The lone survivor of the crash, Group Captain Varun Singh, was shifted to Bengaluru for further treatment, but he succumbed to injuries a few days later. Besides General Rawat, his wife, and Group Captain Varun Singh, the others killed in the accident included Brigadier Lidder, Lt Col Harjinder Singh, Wing Commander PS Chauhan, Squadron Leader K Singh, JWO Das, JWO Pradeep A, Havildar Satpal, Naik Gursewak Singh, Naik Jitender Kumar, Lance Naik Vivek Kumar and Lance Naik Sai Teja.
Shortly after the tragedy, Union Defence Minister Rajnath Singh had informed Parliament that a tri-services inquiry team led by Air Marshal Manavendra Singh will probe into the helicopter crash.
