Concerns Over HAL’s ALH After Recent Crashes

Why in the news?

The recent fatal crashes of HAL’s ALH Mark-II helicopters have raised concerns about safety, prompting investigations and grounding of the fleet. Issues with design and control systems have led to calls for independent inquiries.

Concerns Over HAL’s ALH After Recent Crashes

Overview of the Crashes

  • On January 5, 2025, an indigenous Advanced Light Helicopter (ALH) Mark-II of the Indian Coast Guard crashed during a training sortie in Porbandar, killing all three onboard.
  • This was the second fatal crash in four months, with the previous crash in September 2024 during a medical evacuation mission off the Porbandar coast also claiming three lives.
  • Earlier in March 2023, a Coast Guard ALH crashed in Kochi, but no fatalities occurred.

Concerns Raised by the Crashes

  • The specific causes of the crashes are still under investigation, with the Coast Guard conducting a Board of Inquiry to examine issues related to flying controls and transmission systems.
  • Military aviation veterans have raised concerns about the helicopter’s safety record, calling for independent investigations.
  • Following the latest crash, the fleet of around 300 ALH helicopters has been grounded for detailed inspections and safety audits.
  • Past issues include design flaws, especially with the booster control rods, which can affect control over the helicopter. A replacement program has been initiated to address this.

About HAL ALH Design and Performance:

  • The HAL Dhruv helicopter, which includes the ALH, was developed to replace the aging Chetak and Cheetah helicopters, designed for multiple roles and missions.
  • The design is primarily indigenous, though some critical components, such as the engines and avionics, were initially sourced from abroad.
  • The ALH has received certification from the Directorate General of Civil Aviation (DGCA), confirming its ability to meet international standards.
  • HAL continues to upgrade the ALH through local research and development.
