Airbus said it will resume deliveries of PW1100G powered A320neo jets in late April 2018. The confirmed that engines with required fixes have arrived at its assembly line and the deliveries will resume as scheduled.
Airlines had been grounding A320neo jets powered by PW1100G engines beyond ESN (Engine Serial Number) 450, following engine shutdowns during takeoff and in-flight. Pratt and Whiney recalled those engines and found, faulty knife-edge seal in the high pressure compressor caused the engine to shutdown. The engine manufacturer has been replacing the knife-edge seals with new-design seals in all of those recalled engines from Airbus along with 43 engines at a cost of $50 million.
Last week airbus pushed the delivery dates to May/June but now confirmed to flightglobal that the deliveries will resume this month as scheduled.
