DGCA prohibits ETOPS operations of the Airbus A320neos equipped with PW1100G engines
New Delhi - The Indian civil aviation authority DGCA has suspended ETOPS certification of the Airbus A320neos operated by IndiGo Airlines and GoAir because of the reliability problem of the Pratt & Whitney PW1100G engines.
The Indian Directorate General of Civil Aviation (DGCA) has prohibited ETOPS operations of the A320neos equipped with Pratt & Whitney PW1100G engines due to inadequate reliability.
The agency explicitly points out to the flights to Port Blair in the Nicobar Islands, an archipelago belonging to India and located between the Bay of Bengal and the Andaman Sea. IndiGo and GoAir fly to Port Blair from Kolkata, Bangalore, Chennai, Hyderabad, and Mumbai.
The route from Kolkata to Port Blair requires nearly a 1 and half hour flight. According to DGCA, the restriction has been put into effect for safety reason. The agency stipulates an airport within one hour of flying time, so that the A320neos equipped with PW1100G engines can safely land at the nearest airport on a single engine.
On the routes from the mainland to Port Blair, there are no alternative airports within 60 minutes reach.
Since their entry into service in 2016, 69 PW1100G failures reported by the operators. DGCA has recently issued an airworthiness directive to these operators for more frequent engine checks.
IndiGo has 66 PW1100G-powered Airbus A320neo aircraft, while GoAir owns thirty. Two other major Indian carriers Air India and Vistara also operate Airbus's re-engineered single-aisle but with CFM International's LEAP-1A engines.
