Two Airbus A320 Neo aircraft fitted with Pratt & Whitney (P&W) engines were forced to return to the airports from where they took off on Monday after developing technical snags, the aviation regulator and airlines said on Tuesday.
An IndiGo flight that took off from Delhi for Hyderabad at around 8.30am on Monday returned to the capital after the second engine experienced high vibrations mid-air. The aircraft landed safely at Delhi, following which the aviation regulator, the Directorate General of Civil Aviation (DGCA), grounded it.
DGCA officials, who didn’t want to be named, said the second engine suffered from high N2 (the rotational speed of the engine) vibrations for 15 seconds.
