PARIS—Indian airline IndiGo has flipped its preferred engine supplier, ordering CFM LEAP-1A engines to power 280 Airbus A320neo-family aircraft it has on order—aircraft that will fly alongside IndiGo’s Pratt & Whitney PW1000G geared turbofan (GTF) Airbus narrowbodies.

The Gurgaon, India-based LCC operates a fleet of 232 aircraft, including 216 Airbus A320-family aircraft. Only 17 are powered by CFM engines—all CFM56-powered A320ceos. It also has 108 International Aero Engines (IAE)-powered A320ceos. Pratt is a joint-venture partner in IAE.

The airline has 349 A320neo-family aircraft on order. Delivery of the first LEAP-1A-powered A320neo is scheduled for 2020. The order also includes spare engines and a long-term maintenance support agreement.

IndiGo was an early adopter of the GTF-powered A320neo, but was hit particularly hard by the engine’s teething problems. Operating conditions in India contributed to unexpectedly disruptive parts wear, while the entire fleet was beset with several problems. IndiGo’s operations was hit by regular groundings and at least five inflight shutdowns. Pratt says it has addressed the issues.
