InterGlobe Aviation Ltd, the operator of IndiGo Airlines, announced that it has grounded five additional Airbus A320neo planes due to issues with their Pratt & Whitney engines. The planes should be back in service by the end of August.
“IndiGo has grounded five of its A320neo aircraft due to P&W issues. These aircraft are currently grounded at New Delhi’s Indira Gandhi International Airport,” a source told Times of India.
“The release of additional spare engines has been initiated by P&W so that all aircraft are expected to be back in service in the second half of August,” an IndiGo spokesperson said.
CH-Aviation reports that the grounded aircraft are VT-ITN (msn 7252), VT-ITR (msn 7396), VT-ITT (msn 7504), VT-ITY (msn 6946), and VT-ITZ (msn 7892).
IndiGo has not confirmed whether flight services have been or will be disrupted due to the grounding of the planes.
IndiGo has been facing problems with its A320neo engines since introducing P&W engines into its fleet. Issues include things such as mid-air shutdowns and oil chip detection. Close to a dozen aircraft were grounded in March after multiple mid-air engine failures were reported, leading to over 600 flight cancellations. On certain occasions in the past, IndiGo has made up for grounded aircraft through wet-leased aircraft; at the time of writing, there is no indication on if IndiGo will do the same now.
“Only India is experiencing AOGs due to combustor liner configuration,” said a Pratt & Whitney spokesperson. “We work closely with [IndiGo and GoAir] to support their fleet with the latest configuration engine, which includes the improved combustor liner. “Engine removals are being planned and coordinated with the airlines in India as we continue to successfully retrofit the fleet with the latest-configuration engines. Some aircraft will be out of service temporarily as they perform these removals.”
Over the past year, major malfunctions have been identified in multiple different engine variants. Besides P&W engines on the A320neo, Rolls Roys Trent 1000s, one of the engine types that power the Boeing 787, have been plagued with an issue that caused fan blades to deteriorate more quickly than normal. These malfunctions have led to delays and an increase in aircraft leasing alike, as airlines are forced to ground affected airplanes and are often forced to lease replacement aircraft while enhanced inspections are performed.
