DGCA grounds 11 Airbus aircraft over IndiGo's mid-air engine failure

"Keeping in view the safety of aircraft operations, Airbus 320neos fitted with PW1100 engines beyond ESN 450 have been grounded with immediate effect", the Directorate-General of Civil Aviation said.

Back in 1990, A320 planes operated by then Indian Airlines were grounded following a deadly crash that had killed 89 people. Of the 11 grounded planes, eight belong to IndiGo, while the remaining three are owned by GoAir. The US company added that the "aircraft on ground situation" may take until the end of the second quarter to address.

An airline official also explained that the sudden order by DGCA has also changed the schedule of flights and new schedules are now being worked out. To be sure, only a handful of A-320 Neos in IndiGo and GoAir fleets have this specific series of PW engine.

On Monday a flight operated by IndiGo, India's biggest low-priced carrier, experienced a technical glitch with one of its engines. The said aircraft was one of the 11 Airbus A320neo's powered with Pratt & Whitney PW1100G engines.

IndiGo said these were related to non-detection of chip, carbon seal lining or combustor chamber lining in Pratt & Whitney 1100 series engines. After the replacement, the defective engine is sent to the manufacturer and the planes continue to operate with the replaced engines, the report added.

It was forced to return to Ahmedabad airport, in western India, the airline, which is owned by InterGlobe Aviation, said in a separate statement. On Monday too, hundreds of passengers were stranded across the country as dozens of flights were cancelled by IndiGo and GoAir, reported PTI. "Safety is our top priority". As many as seven departures were delayed.

"While we understand that this may cause inconvenience to some of our passengers, given that we have multiple flights to the same destination, we are proactively re-accommodating all our affected passengers on other flights", Indigo said in a statement.
