An IndiGo Airbus A320neo powered by two Pratt & Whitney PW1127G-JM geared turbofan engines experienced issues with the No. 1 (left) engine during climb from Dehradun, India to Bangalore, India. During climb, the flight crew heard a loud bang followed by a No. 1 engine stall and indications of high exhaust gas temperature and high engine vibrations. The airplane was diverted to Delhi, India for an uneventful landing. Post landing engine inspection of the No. 1 engine confirmed damage to that engine.
Probable Cause of the Incident
The incident was caused by failure of LPT 3rd stage blades in flight as the blade material lacked crack growth resistance and damage tolerance to withstand any impact from material that may have liberated upstream.
