Overview

• On September 4, an Army ALH (IA-1134) reported a tail drive shaft bearing-mount failure at station #9A during flight.
• The Directorate General of EME (Aviation) ordered a one-time check for abnormalities in the TDS across all ALH units.
• HAL has deputed specialist teams and begun forensic inspections, stress and load modelling, design reviews and manufacturing audits to determine the cause.
• HAL described the check as routine, criticized “one-sided” media coverage, and emphasized strict compliance with maintenance directives.
• Army and Air Force Dhruvs remain in service after a May 1 reclearance, while naval and coast guard variants stay grounded following the January Porbandar crash tied to a swashplate fracture.
