Indian Army personnel launched a rescue operation after a Dhruv Helicopter crashed in Jammu and Kashmir’s Kishtwar district on Thursday, May 4, 2023. According to officials, at least three people, including its pilot and co-pilot, were injured in the incident.
Following three accidents in quick succession, Bangalore-based Hindustan Aeronautics Limited has decided to replace a key component of the Dhruv Advanced Light Helicopter to enhance the fatigue tolerance of the made-in-India chopper that serves as the rotary-wing mainstay for the Indian armed forces.
The state-owned aviation major, sources said, would replace an aluminum-made control rod in the gearbox with a steel-made one. It will increase the fatigue tolerance of the copter and better control of the aircraft by the pilots.
The decision to make the change, suggested by a regulatory panel, comes close on the heels of three Dhruv Helicopter crashes on March 8 (Navy), March 26 (Coast Guard), and May 4 (Army). More than 335 Dhruv Helicopters have been produced, of which nearly 300 are in service with the three armed forces.
The last accident involving an Army Aviation chopper led to the death of one soldier and injury to two persons. The Navy and the Coast Guard had grounded their respective Dhruv helicopter fleets in March following two similar incidents involving the platform.
The Indian Air Force, which operates around 70 Dhruv Helicopters, is clearing its choppers for flying in batches. The aircraft that have undergone the tests continue operations, while the rest will be cleared for flying after completion.
Officials at HAL asserted that the Dhruv had an outstanding safety record as it had flown more than 3,75,000 flying hours in the last two decades, and the metallurgical changes in the control rod of the gearbox were being carried out to improve the aircraft’s performance further.
The multi-role, multi-mission 5.5-tonne helicopter has proven its mettle in various utility roles, including lifesaving missions during natural calamities in India and abroad. New Delhi pitches it as one of the defence export items.
