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.
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.
