New Delhi, May 4
Even as the government today admitted that Arunachal Pradesh Chief Minister Dorje Khandu died in a chopper crash, it has left several unanswered questions on safety of VVIPs travelling on board choppers. It has also raised questions on India’s capability as far as search and reconnaissance operations are concerned in inaccessible parts of the Himalayas.
The crashed chopper was as a top-of-the-line Eurocopter and was only 10 months old. It went down without even a ‘May-Day’ distress signal that could be picked by air traffic controller
(ATC).
A source explained that radio contact can be lost with a chopper when a part of it, termed in aviation parlance as the “collective”, fails. This part coordinates the rotation of the tail and top rotors. A failure of “collective” can make a chopper drop like a stone. Otherwise,
modern choppers can make emergency landings.
Pawan Hans, the operator, says the Eurocopter was equipped with Emergency Locator Transmitter (ELT) that works on two frequencies. After the crash, the ELT should have been activated, but it did not. Signals of this can be picked up by satellites or over flying aircraft.
The crashed chopper is the same model of Eurocopter - AS350 B3 - that had created the world record landing at Mount Everest in 2005. Why was the Chief Minister flying in a single-engine chopper as the IAF uses twin-engine Mi-17 choppers to fly VVIPs? asked a senior official.
Sources said the crashed chopper had been leased to the government of Arunachal Pradesh. A twin-engined model was also leased by the company and it was supposed to be flying the Chief Minister. As per the norms of civil aviation requirements issued June 1 last year, single-engine chopper can be deployed only on routes that permit the execution of a forced landing. Also single-engine choppers are not allowed when visibility is low and pilots depend on instrument-aided landing.
The crash also raised questions on India’s reconnaissance abilities. Bad weather - clouds and a drizzle — prevented the IAF Sukhoi-30 from carrying out a successful run to provide images of the spot. The images of the ISRO satellite were also not clear. It also shows that that UAVs could not be deployed.
“It shows lack of radar coverage in that area and exposes a gap in the air defence systems,” said an official while asking why all signals operations in the Himalayas from air-borne operations are not handed over to the armed forces?
It was after four days that debris of the crashed chopper were found today after IAF choppers photographed the rugged mountainous area at a height of some 16,400 feet.
The mountains in the areas of Tawang and south of it in East Kameng and West Kameng district are steep and sparsely populated.
The two pilots of the ill-fated chopper were former Army men and experienced. They had years of experience in the Indian Army’s aviation corps that operates choppers all across the Himalayas from Leh in the west to Arunachal Pradesh in the east.
The Union Cabinet will meet tomorrow specially to condole the death of Dorje Khandu.
