The Directorate-General of Civil Aviation (DGCA) will conduct a special safety audit of the low-cost carrier IndiGo following concerns about the snag-ridden Pratt and Whitney (P&W) engines, which power the airline’s A320 Neo aircraft.
While an annual audit of IndiGo was due in April, a special review will also be done of the airline’s operations and engineering departments, it is reliably learnt.
“We confirm that there is currently a DGCA audit of IndiGo, which is combined with the annual main base audit. IndiGo has received a limited number of show-cause notices. IndiGo has responded accordingly and we can only comment on this matter after we have a discussion with the DGCA,” the airline said in a statement.
No notice to officials
An airline source, however, dismissed reports that show-cause notices had been served on two senior officials of the airline.
Indian carriers IndiGo and GoAir have been inducting the P&W engine-powered A320 Neo aircraft since 2016. The former has 72 of these planes and the latter has 30.
Problems in engine
There have been problems in different parts of the engine, including the combustion chamber, knife edge seal, lift-off seal, front hub corrosion and heating of oil near lift-off seal leading to smoke on board a flight, apart from vibration during climb.
The engine-maker maintains that the problems are taking place as the engines are new into operations.
