IndiGo, GoAir neo plane woes:DGCA orders P&W engine inspection

Aviation regulator DGCA has ordered detailed inspection of 21 Airbus 320 neo planes of IndiGo and GoAir that are equipped with Pratt & Whitney engines, which have been frequently facing technical glitches.

While Pratt & Whitney (P&W) said it is working with IndiGo and GoAir as well as the regulator over the issues, “boroscopic inspection” of the engines has already started.

The Directorate General of Civil Aviation (DGCA) has directed the airlines to carry out inspection after taking serious note of recent incidents, where some IndiGo and GoAir flights had to make emergency landings due to engine issues.

As many as 21 A320 neo planes — that are using P&W engines — would be examined and the exercise is expected to be completed in the next two weeks, a senior DGCA official said.

“Airlines have been asked to carry out one-time boroscopic inspection of all engines which have completed 1,000 hours instead of 1,500 hours recommended by manufacturer and repeat inspection at every 500 hours,” the official said.

In case, the boroscopic inspection is unsatisfactory, the regulator has said the engine operation should be as per manufacturer’s recommendation subject to certain conditions.

However, recommendation below 375 hours shall not be accepted, the official said.

The examination of the engines is being done using boroscope — an optical device that is used for inspecting parts that are generally inaccessible. Hence, the exercise is called boroscopic examination.

Out of the 21 such planes that are being inspected by the DGCA, 16 are with IndiGo and the rest are with GoAir.
