Crisis in Siachen: Two crashes in nine months, army troops face transport crisis

While the Army has been unsuccessfully trying to procure replacement choppers for over five years, an emergency alternative being planned has also not worked out.

Both the crashes involved the indigenous Advanced Light Helicopters (ALH) that had been inducted by Army Aviation to work well beyond their design capacity to supply troops at high altitudes.

The Army is staring at a transport crisis in supplying and maintaining troops at the Siachen Glacier, the world’s highest battlefield, with the main lifeline of soldiers at the extreme heights — light, high-altitude choppers — facing a shortage crisis due to stalled procurement by the last government and two crashes in the last nine months that have raised serious safety questions on the available fleet.

Such is the crisis that the emergency alternative Cheetal choppers — orders for which were placed by both the Army and Air Force — have been tested by manufacturer Hindustan Aeronautical Limited (HAL) in the past month but have failed high-altitude tests in Leh due to a lack of high-performance rotor blades.

The Indian Express spoke to a number of top Army, Air Force and industry officials who acknowledged the seriousness of the situation and expressed helplessness, given that successive crisis management plans were nixed over the past few years.

While the crisis was developing for a while, with the UPA-II government not clearing the Army’s five-year-old proposal to purchase 197 light helicopters at the final stage of procurement due to a CBI inquiry into competitor AgustaWestland that lost during the technical trials, the last nine months have seen at least two “category one” crashes at the glacier that have gone unreported and have raised serious concerns.

Both the crashes involved the indigenous Advanced Light Helicopters (ALH) that had been inducted by Army Aviation to work well beyond their design capacity to supply troops at high altitudes. In August, a chopper crashed while landing close to the Amar helipad on the Siachen Glacier and went down a crevasse. Similarly in March this year, another ALH went down on the northern glacier while landing at a narrow helipad.

“The two accidents occurred at a time when the choppers were taking off or landing at extremely narrow airfields where even a freak wind can cause havoc. Thankfully, in both cases, the pilots managed to jump out in time and only got injured. Both aircraft are damaged beyond repair and one cannot even be recovered,” said an Army official on condition of anonymity.

The reason that the Army has been forced to deploy heavier ALH choppers to supply the brigade-plus deployment of troops on Siachen is that the workhorse Cheetah fleet is on its last legs, having served for over two decades. The entire Cheetah fleet of the Army and Air Force has almost reached the end of its service life, with replacements hard to be found given that the original equipment manufacturer has ceased to manufacture new parts.

“These choppers are essential as they are the last lifeline for troops there. A chopper being able to land at a high-altitude helipad is often the difference between life and death for a soldier suffering from even a very basic illness that gets aggravated by the extreme altitude,” said an Army aviator.

While the Army has been unsuccessfully trying to procure replacement choppers for over five years, an emergency alternative being planned has also not worked out. With the 197 light chopper deal being held up, the Air Force and Army sought to procure 30 light Cheetal choppers from HAL — essentially the same as Cheetahs but with a stronger Shakti engine — as an emergency alternative.

However, HAL has not been able to satisfy the Air Force with the Cheetal due to a very fundamental problem. The European OEMs (original equipement manufacturer) that used to manufacture special “series 85” blades for high-altitude versions of the Cheetal have ceased manufacturing due to lack of demand and more modern choppers coming into the market.

Sources said the OEM has given HAL only 60 rotor blades from its last inventory, adequate only to manufacture 20 choppers and leaving no spares at all for the fleet. While these shall be sent to the Army Aviation, the remaining 10 choppers for the Air Force cannot be manufactured. “It is simply an issue of being obsolete. The type 85 blades are not being manufactured as the world has moved on to new choppers. These blades were developed over three decades ago and are no longer needed anywhere in the world,” an industry official said.

HAL tried to test the Cheetal with a different set of “type 30” rotor blades in Leh last month, but the tests failed as the chopper did not get adequate lift and did not even satisfy HAL’s own test pilots. The main problem being faced by the Air Force on using these blades at high altitudes was excessive vibration beyond permissible limits as well as a reduced right rudder margin.

“There is no way that the Air Force can accept these choppers in the current state as they do not meet our high altitude requirements. As the HAL’s own tests have failed, we do not even need to go and conduct the tests,” an IAF official said.

It is also learnt that HAL proposed to the IAF that its older Cheetah choppers be cannabilised to obtain blades for the Cheetal, a proposal that was shot down as ill-thought and foolish by the Air Force.

The Army is already believed to have raised this particular issue with the new government in place, given that the choppers are critical to troops posted on the glacier. Besides dropping food and ammunition to troops posted at altitudes of over 20,000 feet, the choppers are the only lifeline during extreme weather when land routes shut down. These light choppers are also the only mode of emergency evacuation from high altitude, a role that was at display during last year’s floods in Uttarakhand that saw the choppers undertake the most precarious of missions.

The siachen lifeline 

THE PROBLEM: The brigade-plus troops at Siachen depend on ultra light choppers to supply food, ammunition and also for emergency evacuations. This is the only option during winter months when land routes close.
THE WORKHORSE: Cheetah choppers, bare minimum light helicopters being pushed to their limit to land at helipads at altitudes of over 20,000 feet, have been in use for almost
three decades. These choppers have finished their service life and are flying hazards now.
THE REPLACEMENT: The Army has been trying for almost a decade to purchase new choppers. Most recent contract stalled for over two years as one of the losing competitors — AgustaWestland — is under investigation on corruption charges.
THE CRISIS: With Cheetahs on last leg, Cheetal’s performance not adequate and dubious record of ALH, troops posted at highest battlefield in the world vulnerable.

THE EMERGENCY REPLACEMENTS

 

Cheetal choppers (above): Essentially higher-powered Cheetah choppers made by HAL. But OEMs have stopped manufacturing high altitude blades, so these cannot perform on the Siachen Glacier. Test with normal blades failed.

ALH choppers: These heavier choppers manufactured by HAL are being tried out, but at least two category one crashes (complete loss of aircraft) in the past nine months have thrown up serious safety issues.

    Please don't accuse the pilots of pilot error without verifying the facts.Talking of facts, here are some that might interest you,1) Service Ceiling of ALH Dhruv = 6096 meters (20000 ft)2) Highest Helipad at Siachen Glacier (point sonam) = 6400 meters (21000 ft)6400 meters - 6096 meters= 304 metersThere is a 304 meters gab between the service ceiling and the requirementSo, Yes, these machines are operating either at the very edge of their performance limits or sometimes even beyond them 2009 the army had criticized the ALH for not being able to fly beyond 5000 meters, that's when the mk3 variant was launched with the Shakti engines that increased the service ceiling to 6096 meters but it still falls short of the 6400 meters required of it.

      This is the highest battlefield in the world. No other country has border problem / LOC/ AGPL at such high aludes. Most of the advanced countries have agreed not to attack each other and have robust diplomatic relations. If we do not keep the troops on the AGPL on Siachen then stan Army will attack India , intrude our territory, occupy Nubra and Shyok river valleys and shift the AGPL to Karakoram ranges. That means w of territory north of Khardungla would go to stan. Can we let this happen? On the other hand to maintain the Troops on the AGPL we need to have latest helicopters. Safety and Security of our borders is not a business preposition , Therefore, we need not worry about the cost factor. The HAL must work to produce an advanced helicopter capable of delivering men and material on our highest post an Amar Sonam and Bana post.

        Your comments are clearly wrong. ALH outperforms the Cheetah/Chetak across the board and has come in for excellent praise from the IAF/IA crews flying it. Next, Defense PSUs and R&D labs have made many products that are doing yeoman service in difficult conditions. Your blanket disparagement is both unnecessary as well as inaccurate.

          Give it to staan and then use Dhruv to supply their troops. Two birds with one stone, eh? No more spending of Indian rupees or lives on that inhospitable sheet of ice and also earn valuable foreign exchange. But the only problem is stan is broke and India Prime Minister is now, in case you missed, is that ruthless Hindu nationalist Modi. The appeasing PM MM Singh is no longer there I believe.

              I salute the troops deplo in Siachen,which is very tough in terms of its alude and weather conditions.I hope, HAl will be in a position to improve ALH and also Cheetal to meet the service requirements such weather conditions any helicopter is likely to get in to problems as the wind and visibility changes quiet often. I wonder any other helicopters all over the world are operating in such hostile weather conditions

                  Dear Air Warrior, Let's please stay focused on the point that I am making. The two Dhruv MkIII accidents on the Glacier were NOT due to any technical or systems malfunction. You may please check the facts.The case for replacement of Cheetahs is definitely justifiable, as I already said. A light helicopter is required to land on those tiny postage stamp sized helipads and on those helipads atop small ice-pillars.However, fudging the statistics and bashing the Dhruv, so as to butress this replacement case is DEAD WRONG. Also, having flown the Mi-17, Cheetah and Dhruv Mk III on the Glacier and in the know of all performance details, I stand by my statement that the Dhruv Mk III FAR outperforms either the Cheetah or any of its intended replacements in terms of performance and handling. Have a word with the boys in the Sqn /Units out there in the field flying the Mk III to verify the facts, if you will.And finally if I may suggest, we also need to throttle back on the scaremongering on just about everything indigenous being absolutely rotten and that only pure imports will be able to save the day. That's perfect talk for perhaps only a banana republic and is a route that leads to trouble. What is needed is a strong industrial complex based in-country (PSU, Private and Joint Ventures) supporting the military. However, that's another discussion!

                    This is the THIRD time today I am posting my comment. Dear Indian Express“Journalism of Courage” – kindly have the courage to post my comment – which isperhaps an inconvenient truth. Unless of course, you are lobbying on behalf ofthose foreign vendors who are attempting to resusicate their case for thereplacement of the Cheetah.The Army or the IAF should not attempt to fudge the truth regarding the ALH(Dhruv) crashes on the Glacier, both of which were caused by pilot error.Whereas their case for replacement of the Cheetah for use on small ice-pillar helipads on the Glacier is definitely justified, the attempt to fudge the case of ALH (Dhruv)being a failure on the Glacier is NOT pardonable. Please be advised that theALH (Dhruv) is operating well within its limits on the Glacier and is the onlyhelicopter in its weight cl in the world to be able to do so. It faroutperforms either the Cheetah or its planned replacement – a fact that isagain well known.Its getting fashionable to bash the indigenous ALH (Dhruv), often withoutreason – and this is one of them. The case for a light-weight helicopterreplacement is well justified –however attempting to fudge statistics to buttress the case is DEAD WRONG.And kindly do publish my comments this timearound, dear Sir!Else, it will be quite clear that this is a paid news article on behalf of the potential foreign vendors!

                        There is factual error in the report - both the Army ALH (Dhruv) crashes were caused due to pilot error and not any mechanical failure. Whereas the need and urgency for the Cheetah replacement is well understood and justified for small helipads, the Army should desist from fudging the facts regarding the ALH (Dhruv) to buttress their case. Bad-mouthing the indigenous ALH (Dhruv) needlessly appears to be a fashionable thing- a far cry from what other countries do for their indigenous products. Also please face the hard facts - the ALH is very well capable of operating on the Glacier and not "flying well beyond the limits" as brought out here. The ALH far outperforms the Cheetah and even its planned replacement- that's also a well known fact.

                          What's happened with the HAL - LUH program ?AK Anthony was the worst defense minister in the history of India and the only thing he left behind is a big mess. Even the LCA is NOT ready. In his 6 years in office he did only one thing - NOTHING. Better to have no Defense minister than have somebody like AK Anthony. He even fought with VK Singh and made a big mess.

                              I think the new Defence minister must get the best light helicopter that's in the market ASAP ...at least for the Siachen Glacier ....let's forget the history of the procurement process for a while and give the soldiers at the Glacier immediate support .Further inductions can take its time thro the normal procedure but fast tracked by the new Govt ....the military has lost valuable time in procuring new equipment from the policy paralysis of the previous govt ...hope the military can get speedy justice from the BJP Govt now !!

                                The Dhruv does not have a great track record vis a vis compeion even in India , ( it can't replace a light helicopter that might need to replace the Cheetah ...it's too big for that cl ).....not to mention export markets where it mostly got gifted ....the above seems to be written by someone scared that HAL is heading to get disinvested by the new Govt coz it doesn't have a credible product in any range be it trainers , helicopters or fighters .....the writing on the wall is that the only option for the nation is to have to look for the private sector to rise to the occasion thro the FDI route . Our Defence PSUs and R&D labs have spent thousands of crores with very little returns to National Security !! And if you scratch beneath the surface scam ridden as well !!God help the military ...most can't even talk to the press directly to give their side of the story !!

                                  The essence of this article is that the country has been unable to provide a replacement to the Cheetah that has become obsolete over so many years of operations . The Dhruv was inducted into the small glacier helipads ...where it has no business to be in ....( except the larger firmer ones ) to fill the gap since the soldiers don't have any other options and we can't let them die ......why is everyone trying to be protective of the Dhruv vs the pilots error when they are not meant to be there .....Please focus on the core issue ...ie get the Army and the IAF the latest helicopters that would do the job and for the sake of the lives of our brave soldiers please don't best around the bush or chase Red Herrings !!

                                      I think India should reduce troop size in Siachen. We spends crores of rupees everyday on Siachin troop maintenance . Its time to cut unnecessary defense expenditure. India should develop better railways network in Ladakh instead of spending everything on Siachen.
