Indian low-cost carrier IndiGo has temporarily grounded five Airbus A320neo jets at New Delhi airport, following Pratt and Whitney engine issues. Grounding 5 aircraft would force the airline to cancel almost 800 flights a month.
The airline awaits for spare PW1100G engines and these five aircraft are expected to be back in service in the second half of August 2018.
In February this year, IndiGo grounded 3 A320neos, following engines shutdown during takeoff, and later found problems with knife edge seal on the modified aft hub of the high-pressure compressor.
Again in March this year, Indian DGCA ordered the airline to ground 11 A320neos for the same engine issues.
Issues with PW1100G engines have forced several A320neos grounded since 2016.
IndiGo operates 39 Airbus A320neos
