India's largest carrier IndiGo has landed the single-largest engine order in CFM International's history, signing a memorandum of understanding at the Farnborough International Airshow 2026 for more than 1,000 LEAP-1A turbofans to power 510 incoming Airbus A320neo family aircraft. The July 20 deal cements a decade-long relationship between the low-cost carrier and the GE Aerospace-Safran engine joint venture.
A Record-Setting Engine Order
The MoU covers over 1,000 LEAP-1A engines destined for IndiGo's 510-aircraft A320neo family backlog, making it the largest single order ever placed for the LEAP series. CFM's Willie Walsh-era customer expansion continues to reshape the narrowbody engine market, with India now CFM's third-largest country by installed base. Five Indian carriers currently operate more than 400 LEAP-powered jets and have over 2,000 engines on order.
India MRO Facility And Long-Term Support
Beyond the sheer volume, the agreement establishes a broad long-term framework built to secure IndiGo's supply chain for decades. CFM will directly support IndiGo in standing up a dedicated engine maintenance, repair and overhaul facility in India, backed by an aftermarket agreement guaranteeing spare-parts availability, predictable maintenance costs and dispatch reliability across the fleet. Technical upgrades including high-pressure turbine (HPT) durability kits and reverse bleed systems (RBS) will be integrated to help engines withstand the hot, harsh operating environments common on South Asian routes.

Fits The Farnborough Order Frenzy
The IndiGo mega-MoU lands alongside a wave of Farnborough orders that included IndiGo's own 810-aircraft avionics deal with Honeywell and BOC Aviation's 300 CFM LEAP engine commitment. Combined with widebody bets such as Riyadh Air's 787 top-up, Monday saw multiple engine and airframe records topple in a single day.
What It Means For The Narrowbody Race
"The LEAP engine's industry-leading proven reliability makes it the ideal choice to support our scale, operational resilience and sustainability ambitions," said Willie Walsh, IndiGo's CEO Designate. IndiGo first flew CFM56-5B engines on its A320ceo aircraft in 2016 before selecting LEAP-1A powerplants for the A320neo fleet in 2019. With Pratt & Whitney's GTF fighting for share in the same segment and CFM's rival RISE open-rotor engine still years away, the CFM-IndiGo pact locks in the world's fastest-growing airline for the current LEAP generation deep into the 2030s.
