India’s biggest airline IndiGo has grounded three A320neo aircraft effective from February 9, 2018 due to engine problems. IndiGo said in a statement “We confirm of receiving the recommendations by Pratt & Whitney as well as EASA (European Aviation Safety Regulator) with respect to the A320neo aircraft powered by PW1100G – JM engines”
EASA issued emergency restrictions on airplanes powered by PW1100G engines after reported “several occurrences of engine in-flight shut-down (IFSD) and Rejected Take-Off (RTO) on certain Airbus A320neo family aeroplanes”.
The DGCA official of India said IndiGo has three such aircraft, which have been grounded and further said “The above issue is entirely different from No. 3 bearing failure and combustion chamber failure experienced initially by PW1100 engines, which have been addressed.”
Last year also, IndiGo airlines had to ground several A320 airplanes due to engine issues, but were compensated by Pratt and Witney for the losses incurred.
According flight data, out of 100 plus A320neo planes fitted with PW1100G – JM engines delivered globally, 11 aircraft are fitted with this particular configuration on both engines and around 21 aircraft are fitted on one of their engines.
