  IndiGo flight returns to Lucknow soon after take off
  NEW DELHI: Troubles on the Pratt Whitney's (PW) snag-prone engines for the Airbus A-320 Neo show no sign of ending. An IndiGo Neo flying from Lucknow to Kolkata on Friday had to return to Lucknow after the aircraft reportedly had an engine stall after excessive vibration. Twin-engine aircraft can land safely on one engine and this Neo (VT-IVG) operating as 6E-866 also did so and is now grounded in Lucknow.
  High vibration is the latest problem afflicting PW engines for the A320 Neos. In India, IndiGo and GoAir use PW-powered Neos. Almost 10 cases have been reported of high vibration in recent past here. A senior official of the Directorate General of Civil Aviation (DGCA) said the "manufacturer (PW) is aware of this (vibration issue) and is working on it".

  While Pratt Whitney engines on the A-320 Neo troubles are mounting, aviation authorities here say there is no cause for concern. "A320 Neos powered by Neo engines are safe to fly. We are monitoring the situation very closely. We have very strick checks in place for the Neo Pratt engines. They wanted us to relax the strict checking norms and we refused," said a senior DGCA official.
