The Aviation regulator Directorate General of Civil Aviation (DGCA) on Friday asked Indigo to replace all Pratt & Whitney (P&W) engines on its Airbus A320neo family aircraft with new P&W power units after frequent glitches were reported in recent flights.

The country’s air safety watchdog said that the decision was taken after ‘considerable deliberations. It has fixed January 2020 as the deadline for the replacement of all the faulty engines.

“You will appreciate that four successive events have not happened ever before and therefore, we call for urgent and effective action. We regret the inconvenience but we need desperate measures to put things in order,” the DGCA was quoted saying in a media report.

The carrier is the biggest client for A320neo planes and since the beginning, Indigo has faced issues with the Pratt & Whitney engines that resulted in grounding its planes on several occasions.

In a similar decision, the DGCA on Monday ordered GoAir to modify 29 Airbus A320neo aircraft fitted with Pratt & Whitney engines within a period of 15 days to avoid them being grounded.
