New Delhi: In yet another Pratt & Whitney (PW) engine trouble for IndiGo, a Kolkata-bound Airbus A320 (Neo) had to return to Bagdogra soon after take off on Monday. An earlier version of PW engine, which Indian aviation regulator wants off the wings in all IndiGo Neos by January-end, had high vibrations on the aircraft (VT-IJZ) during climb and stalled. Since twin engine can land safely on one engine, this one did so at Bagdogra.
Comments from IndiGo and PW have been sought on the latest engine trouble.
"Flight 6E-958 Bagdogra-Kolkata had air turn back to Bagdogra due to high vibration and stall. The aircraft landed safely," said sources.
"On inspection, low pressure turbine third stage blades were found damaged on this unmodified engine," sources added.
Given the spate of snags on PW unmodified engines on A320 Neos of IndiGo, the Directorate General of Civil Aviation (DGCA) has directed the airline to have only modified PW engines on all its Neos by next month end. Neos with unmodified PW engines will have to be grounded after that till engine replacement takes place.
