New Delhi - Directorate General of Civil Aviation (DGCA) of India has ordered a special safety audit for the planes of the low-cost IndiGo after several obvious failures.
The Indian regulator ordered the audit after non-reported incidents, improper maintenance practices, missing maintenance documentation, and repeated Pratt & Whitney engine failures on its A320neo fleet.
The airworthiness and air safety teams from DGCA are now inspecting the MRO (Maintenance, Repair Overhaul) practices of the carrier.
"We confirm that there is currently a DGCA audit on IndiGo which is combined with the annual main base audit. We have received a limited number of show-cause notices," the airline said in a statement.
IndiGo and GoAir, which operate Airbus A320neos powered by PW1100G engines have been facing problems with these engines, since their entry into service three years ago.
The budget carrier IndiGo is the largest airline of India in terms of fleet size - 219 aircraft in total. The company has 74 Airbus A320neo family aircraft in service and 366 on order.
