DGCA of India has grounded 11 Airbus A320neo jets powered by certain series of Pratt & Whitney engines following a mid – air engine failure of Pratt and Whitney engine on IndiGo A320 jet this morning.
The Indian Authorities grounded all aircraft powered by PW1100G engines beyond ESN (Engine Serial Number) 450 with immediate effect, which includes 8 IndiGo A320neo and 3 Go Air A320neo jets.
The decision comes hours after an A320 neo aircraft of IndiGo suffered mid-air engine failure and made an emergency landing at Ahmedabad airport this morning.
“Both IndiGo and GoAir have been told not to refit these engines, which are spare with them in their inventory,” the Directorate General of Civil Aviation (DGCA) said in a release.
On February 9, EASA had issued an emergency airworthiness directive for A320 neo planes fitted with PW1100 engines having a particular serial number.
India’s largest airline, IndiGo had to replace Pratt & Whitney engines on its 32 A320 Neo aircraft at least 69 times in the period of May 2016 to November 2017. IndiGo says these are related to non-detection of chip, carbon seal lining or combustor chamber lining in Pratt & Whitney 1100 series engines. The airline calls these engine ‘glitches’ and ‘non-safety’ issues. Indigo’s boroscopic tests detected these anomalies in 69 instances.
