Mumbai: Aviation regulator DGCA has issued a show-cause notice to budget carrier IndiGo's Chief Operating Officer and engineering head over the Pratt & Whitney engines issues, sources close to the development said.
The Directorate General of Civil Aviation (DGCA) is also conducting a special safety audit of the airline's operations and engineering, they said.
Indian carriers IndiGo and GoAir, which have Pratt & Whitney-powered Airbus A320 neo planes, have been facing problems with these engines, manufactured by the US firm since their induction in the fleet three years ago.
"The DGCA issued show-cause notice last week to IndiGo's chief operating officer Wolfgang Prock-Schauer and engineering head S C Gupta over the Pratt & Whitney engines issues," a source said.
