In a significant aviation incident, the Directorate General of Civil Aviation (DGCA) has launched an investigation into the uncommanded deployment of the Ram Air Turbine (RAT) on Air India’s Boeing 787-8 Dreamliner during a flight to Birmingham. The unexpected activation of this critical safety system has raised concerns about the aircraft’s operational integrity and safety.
What Happened?
The incident occurred on Air India Flight AI113, en route from Delhi to Birmingham. While cruising at altitude, the RAT—a device designed to provide emergency power in case of electrical failure—was deployed without command. This activation was neither initiated by the flight crew nor triggered by any apparent system malfunction.
The crew followed standard procedures, assessed the situation, and safely landed the aircraft in Birmingham. All passengers and crew disembarked unharmed. However, the uncommanded RAT deployment led Air India to ground the aircraft for a thorough inspection.
What is a Ram Air Turbine (RAT)?
The RAT is a vital safety feature in modern aircraft like the Boeing 787 Dreamliner. Stowed during normal operations, it automatically deploys in emergencies, such as a loss of engine power, to generate hydraulic and electrical power for essential systems. Its unexpected deployment under normal conditions is highly unusual and potentially risky.
DGCA’s Investigation
The DGCA is conducting a comprehensive probe to identify the root cause of the incident. Investigators are examining potential mechanical, electrical, or software issues and assessing whether this is an isolated case or indicative of a broader problem with the Boeing 787 fleet.
Air India has provided flight data records, maintenance logs, and full cooperation to the DGCA. Boeing has also been notified and is expected to assist in the investigation. The affected aircraft, registered as VT-ANH, remains grounded pending the investigation’s outcome.
Implications for Air India and Boeing
This incident comes at a pivotal moment for Air India, which is striving to enhance its reputation under Tata Group ownership. The Boeing 787 Dreamliner is a cornerstone of its long-haul operations, and any safety concerns could impact passenger confidence.
For Boeing, the incident adds to the scrutiny surrounding the 787 program, which has faced production and delivery challenges in recent years. While the Dreamliner is generally reliable, such incidents could raise questions about its safety.
Passenger Safety Remains Paramount
The DGCA has reaffirmed its commitment to passenger safety, urging airlines to conduct additional checks on their Boeing 787 fleets. Passengers are advised to stay updated on developments from Air India and the DGCA.
As the investigation unfolds, further details will be shared to ensure transparency and safety in aviation operations.
