On July 15, 2019, an IndiGo Air Airbus A320-271N Neo, powered by two Pratt & Whitney PW1127G-JM geared turbofan engines, encountered a No. 1 (left) engine failure during a flight from Goa Airport to Ahmedabad Airport, India. The failure was preceded by an ENG#1 stall warning, high vibration, and high exhaust gas temperature.
Flight Actions
