    Dhruv helicopters back in action after Sitapur crash
    Published August 27, 2014 | By admin

    The Indian Air Force has resumed flying the indigenous Dhruv Advanced Light Helicopters (ALHs) after completing a fleet inspection following a crash in Uttar Pradesh on July 25.The IAF temporarily suspended ALH operations after manufacturer Hindustan Aeronautics Limited (HAL) recommended certain checks, which were carried out. The entire exercise took almost a month.

    IAF sources said the ALH fleet was given the go-ahead to resume operations on Friday. An inspection team checked all the 40 Dhruvs flying with the IAF.

    The inspection of the fleet was necessitated by the fact that the crash of an ALH at Sitapur near Lucknow was attributed to technical failure. It was a smooth flight with no adverse weather, but things went suddenly wrong for the crew, forcing the pilot to send a distress call.

    The helicopter was being flown by an experienced hand, Wing Commander T.B.N Singh, commanding officer of the 111 helicopter unit. The pilot and co-pilot were killed in the crash along with five airmen. It is common to put the entire fleet under inspection after a crash due to technical failure, said officials.

    The 111 helicopter unit was the first to induct the Dhruv Mk III, which is the latest version fitted with the more powerful Shakti engine. The added power is an advantage at high altitudes. The helicopter also comes with an improved electronic warfare suite and warning systems and reduced vibration.

    The helicopter that crashed in July had been serviced just days before the incident and had flown over 500 hours. A problem with its control systems is suspected to be behind the technical failure, though the probe is yet to be concluded.

    The Dhruv helicopters, which are also used by the army and navy, have been involved in a number of crashes.
    The army too had stopped flying ALHs after the July 25 crash. A similar inspection of the army’s fleet was also being carried out.

    The twin-engine ALH has become a key part of air sustenance operations in forward areas of Jammu and Kashmir.

    Dear @layman

    in a post about HAL helos - LAH/LUH/LCH some time back

    you had expressed concern with the rotor blades - pointing out that the company which supplies rotor blades for ALH was in the process of closing down - so how will HAL fulfill all these orders

    Here is the "INDEGENOUS" Answer

    you can tick off one more component INDEGENISED and cross off from imported parts of INDEGENOUS products

    It would be a good news... ANd sure it is a good news.
    I jus want to know that does these Rotor Blades Support High Altitude. If so then they have done a great job.

    The folding blade tech means that IN will be the biggest buyer of ALH if it is taken to it.

    Yep. Clarify me that these Hinged Blades cant be used in High Altitude. I guess we had only issues with High ALtitude Blades.

    Correct me if am not wrong, Still the Pitch Bearings are imported...

    i think if HAL has decided to replace the imported Rotor Blades with these Rotor Blades, then of course these must have the same spec.

    so it is safe to take it that these should Support High Altitude.

    by the way could these Rotor Blades be used by LCH & LUH also ?

    What we need are rotors that fold under power. Manually-folded blades already exist on Dhruv. BTW, Navy recently ordered 16 more
    examples of the ALH in addition to the 8 in service to make a total of 24. However it's not clear if the the new composite blades are
    power-assisted folding or again the same manual folding. I hope it comes under power because it's unlikely to get big orders from IN for roles such as ASW (it has already been decided Dhruv isn't suited for that though) until it gets them. Although that's not where all the problems end.
