DGCA Investigates Air India 787 Emergency Turbine Deployment Over UK

India's Directorate General of Civil Aviation (DGCA) has launched an investigation into the unexpected mid-air deployment of the Ram Air Turbine (RAT) on an Air India Boeing 787 Dreamliner flight AI117 from Amritsar to Birmingham. The RAT, an emergency power system that automatically activates when there is a total loss of engine power, deployed during the aircraft's final approach despite all electrical and hydraulic systems functioning normally. The aircraft landed safely and was subsequently grounded for a thorough inspection. This incident is notable due to the rarity of RAT deployment without engine failure and follows recent scrutiny of the RAT system after a previous Air India Boeing 787 crash. The Federation of Indian Pilots has urged the DGCA to inspect all Boeing 787 aircraft operated in India to ensure safety. The DGCA has assigned a dedicated officer from the Directorate of Air Safety to conduct a detailed investigation into the cause of this anomaly.
