DGCA inspecting some IndiGo & GoAir planes following security alert


Fellow Dow stock General Electric (GE), which makes the rival Leap engine, climbed 3.4%, though the Leap has run into its own production problems.

IndiGo and GoAir are the two domestic carriers that operate A320 neo planes powered with P&W engines.

About 113 Pratt & Whitney engines now equip the A320neo family of aircraft, which are used by 18 customers.

According to Pratt & Whitney, the latest issues do not involve engines for the Embraer E2 family and the Bombardier CSeries, but are limited to the Airbus application.

The DGCA official said IndiGo has three such aircraft, which have been grounded.

Last year, the carrier had to ground a few aircraft and they began flying again after the issues were fixed. But Airbus has still parked around 30 otherwise completed aircraft at its manufacturing sites in Toulouse and Hamburg awaiting engines.

Passengers have also been offered refunds, IndiGo said.

A senior DGCA official said three Airbus A320neo planes of IndiGo have been taken out of operation because of some technical issues.

The EASA said that "several occurrences of inflight shutdown and rejected takeoff have been reported on certain" A320neo-family aircraft powered by GTF engines.

Airbus too has issued an alert, saying these aircraft should not be used till further instructions.

The Pratt & Whitney engines are installed in about 113 Airbus planes across 18 airlines - the majority of which are in India and Europe, a Pratt & Whitney spokesperson told CNNMoney. However, Indian LCC IndiGo confirmed it has grounded three A320neos after the EASA EAD was issued. In addition to the grounding of aircraft by IndiGo, Airbus has postponed deliveries of the aircraft with the PW engines.

"We have identified the potentially affected engines and communicated with our customers", the Pratt spokesperson said.

In a separate statement, P&W said that with the support of Airbus, it is in close contact with customers to address the results of a recent finding related to the knife edge seal in the High Pressure Compressor (HPC) aft hub on the PW1100GJM engine powering the A320 neo planes.
