IndiGo grounds 3 A320 neos after engine-failure warning

MUMBAI: Low-cost airline IndiGo grounded 3 Airbus 320 neo (new engine choice) airplane on Friday after the European aviation regulator issued an emergency directive elevating issues over a potential "dual engine" failure in such airplane which are fitted with a undeniable category of Pratt and Whitney engines.
A320 neos, made by means of European airplane manufacturer Airbus and powered by means of American aerospace manufacturer Pratt and Whitney's (PW) turbofan engines, were having engine issues since the time they have been inducted into world airline fleet two years ago. Following the European Aviation Safety Agency's (EASA) order, Airbus announced that it has stopped handing over A320 neo jets fitted with PW 1100 engines.

IndiGo is the biggest operator of twin-engined A320 neo airplane on the earth; all their 32 neos are fitted with PW 1100 engines. IndiGo A320 neos have had essentially the most screw ups globally: a complete of 69 cases of single-engine failure in the 18 months between March 2016 and September 2017.

The Indian regulator, Directorate General of Civil Aviation (DGCA), which permitted the order, did not ground the entire A320 neo fleet.

The European Aviation Safety Agency caution is only for a selected "subpopulation" or sub-category of engines within this inaccurate engine staff.

The EASA caution was necessitated by means of a number of occurrences of engine in-flight shut-down and rejected takeoff involving A320 neo circle of relatives aeroplanes, said a top DGCA professional.

The EASA caution was necessitated by means of a number of occurrences of engine in-flight shut-down and rejected take-off involving A320neo circle of relatives aeroplanes, said a top DGCA professional. "While investigation is on to determine the root cause, EASA's preliminary findings indicated the particular subcategory of PW1100 engines was more susceptible to dual engine failure," he added. Airbus has also issued an alert to operators of A320neos, offering instructions to de-pair the affected engines and discontinue operations over routes the place the closest runway is more than an hour away.

The DGCA professional wired the above factor is fully different from issues of bearing failure and combustion chamber failure experienced first of all by means of PW1100 engines, which, he said, were addressed.


IndiGo's cases of single-engine failure in 18 months averaged one a week. However, if one engine fails, a twin-engine airplane like an A320 can safely land with the opposite operative engine. Yet what was brow-raising was the exceptional frequency with which these engine screw ups came about, a global file, said aviation mavens.


In the previous 3 a long time, technological advances have made engine screw ups a rare occurrence, with handiest about 25 (in multi-engine airplane) a 12 months international, or one engine failure for each and every million flights. Currently, India is the world's largest operator of A320neos fitted with the inaccurate PW 1100 engines. Yet it was handiest on Friday, after EASA raised an alarm, that the 3 A320 neos have been grounded. The EASA directive does now not call for the grounding of A320neo airplane wherein handiest some of the two engines belong to the sub-category concerned.


According to a media report, Airbus said there are handiest 43 engines international of this sub-category. How a lot of them are with IndiGo isn't identified. IndiGo did not pass into the query. "Airbus and Pratt are working in close cooperation and will be swiftly communicating on the way forward to regain normal operations and resume aircraft deliveries," said the IndiGo remark.
