Two engine choices

Every neo comes with a choice of two engines: the CFM International LEAP-1A or the Pratt & Whitney PW1100G-JM geared turbofan (GTF). Airbus press release: A320neo with CFM LEAP-1A engines receives joint EASA and FAA Type Certification (May 2016) EASA model numbers tell you the engine: A320-251N, -252N and -253N have CFM LEAP-1A engines; A320-271N, -272N and -273N have Pratt & Whitney PW1100G-JM-series engines. EASA: Type-Certificate Data Sheet EASA.A.064, Airbus A318, A319, A320, A321, Issue 62, 26 June 2026 (PDF)

On EASA’s data sheet the Pratt & Whitney neo engines appear under IAE, for example ‘Two IAE PW1127G-JM Geared Turbo Fan jet engines’ on the A320-271N. EASA: Type-Certificate Data Sheet EASA.A.064, Airbus A318, A319, A320, A321, Issue 62, 26 June 2026 (PDF) The A321XLR’s certified engines are LEAP-1A33X-series (A321-253NY) and PW1133GR-JM-series (A321-271NY).
