NEW DELHI : Aircraft engine maker Pratt and Whitney (P&W) has roped in Air India Engineering Services Ltd (AIESL) to provide maintenance, repair and overhaul (MRO) services to domestic carriers such as IndiGo and GoAir. “AIESL will service PW1100G-JM engines at its facility in Mumbai," the company said in a statement on Thursday.
The PW1100G-JM geared turbofan (GTF) engine powers five aircraft platforms, which include the Airbus A220, the Airbus A320neo family and the Embraer E190-E2 that are already in commercial service and the Mitsubishi Regional Jet and Irkut MC-21 aircraft undergoing flight testing. IndiGo and GoAir, the two Indian operators of A320neo planes with P&W engines, have faced several snags with the engines.
The two carriers, which have together about a fourth of the global fleet of about 585 A320neo planes, have so far seen 26 cases of P&W engine failures related to low pressure turbines (LPTs) out of a total of 56 such cases worldwide.
P&W said the company has addressed most issues other than “third stage" LPT failures.
AIESL’s introduction to GTF maintenance will be a phased approach, starting with engine upgrade and module exchange capabilities, the company added.
IndiGo and GoAir have been permitted to fly their A320neo planes by the Directorate General of Civil Aviation (DGCA) on the condition that at least one of the two engines on an A320neo plane has been modified, until modifications are made to all the faulty P&W engines by May-end.
A senior government official said recently that IndiGo had 152 modified engines at the end of February and is expected to replace all 212 older engines with modified ones by May-end, thus reducing chances of on-air snags. IndiGo has 106 A320neo aircraft in its fleet.
GoAir, which has a fleet of 43 A320neos, is expected to have up to 67 modified engines by March-end, the DGCA official said.
