India Grounds Airbus A320Neo Jets With Faulty Pratt Engines – Bloomberg

India took the drastic measure of grounding all Airbus SE narrow-body planes powered by the latest Pratt & Whitney engines, removing the aircraft from the country?s skies after a series of in-flight incidents.

A320neos with even one Pratt engine featuring a seal found to cause vibrations are no longer allowed to fly, India?s Directorate General of Civil Aviation said in a statement Monday. The unilateral action is at odds with the European Aviation Safety Agency, the primary regulator for Airbus planes, which repeated guidance that the jets are safe if they have a single affected turbine.

The Indian move immediately grounded eight aircraft at IndiGo, the nation?s largest carrier, and three at?GoAirlines India Pvt. It comes after three in-service shutdowns of aircraft with one PW1100 engine featuring the seal, two of which occurred in the past week, according to the?DGCA. Shares of IndiGo fell as much as 3 percent in Mumbai on Tuesday.

?Pratt and Whitney engine issues will take a while to get resolved,? analysts at Mumbai-based brokerage Edelweiss Financial Services Ltd. wrote in a research note on Tuesday, recommending selling the stock. ?This will hurt IndiGo in the near term and may lose market share to domestic peers.?

The glitch with the so called?knife-edge compressor seal is the latest in a series of expensive problems for Pratt in its development of the geared turbofan engine model. The manufacturer, part of United Technologies Corp. had proposed a fix that would see at least one engine featuring an older seal reinstated on planes while it worked on a more permanent solution.

Nothing Concrete

Under the Pratt plan, all defective components would be replaced by early June, requiring some planes to fly with one affected engine for almost three more months. That?s not acceptable, according to the Indian regulator, which said the manufacturer had ?no concrete proposal in place at this stage.?

United Technologies shares fell 1.9 percent on Monday in New York, while Airbus fell 2.5 percent in Paris, the biggest loss in a week for both.
