<p>Following three accidents in quick succession, Bengaluru-based Hindustan Aeronautics Limited has decided to replace a key component of the Dhruv Advanced Lightweight Helicopter to enhance the fatigue tolerance of the made-in-India chopper, that serves as the rotary-wing mainstay for the Indian armed forces.</p>.<p>The state-owned aviation major, sources said, would replace an aluminium-made control rod in the gear box with a steel made one. This will increase the fatigue tolerance of the copter and better control of the aircraft by the pilots.</p>.<p>The decision to make the change, suggested by a regulatory panel, comes close on the heels of three ALH crashes on March 8 (Navy), March 26 (Coast Guard) and May 4 (Army). More than 335 ALH have been produced so far, of which nearly 300 are in service with the three armed forces.</p>.<p><strong>Also Read | <a href="https://www.deccanherald.com/national/north-and-central/defence-minister-rajnath-singh-inaugurates-iaf-heritage-centre-in-chandigarh-1216791.html" target="_blank">Defence Minister Rajnath Singh inaugurates IAF Heritage Centre in Chandigarh</a></strong></p>.<p>The last accident involving an Army Aviation chopper led to the death of one soldier and injury to two persons.
