India’s largest carrier, IndiGo Airlines, has signed a landmark memorandum of understanding (MoU) with CFM International for the purchase of more than 1,000 LEAP-1A aircraft engines, marking the largest single LEAP engine agreement in CFM’s history. Announced at the Farnborough International Airshow 2026, the deal will power 510 Airbus A320neo family aircraft that IndiGo has already ordered, reinforcing the airline’s long-term fleet expansion strategy.

Beyond the record engine order, the agreement also includes plans to establish a Maintenance, Repair and Overhaul (MRO) facility in India and a long-term spare parts support program. The move is expected to strengthen IndiGo’s operational resilience, reduce maintenance turnaround times, and support India’s ambitions to become a global aviation maintenance hub.

Record-Breaking LEAP Engine Order

The agreement represents the biggest engine purchase ever secured by CFM International, the joint venture between GE Aerospace and Safran Aircraft Engines.

The engines will power IndiGo’s expanding fleet of Airbus A320neo family aircraft, supporting the airline’s rapid domestic and international growth over the coming decade.

Supporting IndiGo’s Massive Fleet Expansion

The engine order complements IndiGo’s ambitious aircraft acquisition strategy.

In 2023, the airline placed a record order for 500 Airbus A320neo family aircraft, one of the largest commercial aircraft purchases ever made by a single airline. The latest engine agreement ensures a dedicated supply of propulsion systems for those aircraft while providing flexibility for future fleet growth.

As India’s aviation market continues to expand, IndiGo is investing aggressively to increase capacity, add new international routes, and maintain its position as the country’s largest carrier. Rivals are scaling up too: Air India plans to add 60 aircraft over 18 months and is targeting a 30% domestic market share within two years.

India to Get New Engine MRO Facility

One of the most significant aspects of the agreement is the proposed establishment of a CFM engine Maintenance, Repair and Overhaul (MRO) facility in India.

The facility is expected to:

  • Service IndiGo’s growing LEAP-powered fleet.
  • Reduce dependence on overseas repair centers.
  • Improve engine turnaround times.
  • Enhance spare parts availability.
  • Strengthen India’s aviation maintenance ecosystem.

The agreement also includes long-term support for spare engine components, helping the airline manage maintenance schedules more efficiently amid growing global demand for aircraft engines. A site, timeline and investment figure for the proposed facility have not been disclosed.

Strategic Importance for CFM and IndiGo

For CFM International, the agreement reinforces the LEAP engine’s position as one of the world’s most widely adopted narrow-body aircraft engines.

For IndiGo, the deal secures long-term engine availability at a time when global airlines continue to face supply chain constraints and extended maintenance waiting periods. The airline is also taking greater control over its maintenance operations by investing in local infrastructure and long-term engine support.

Aviation Industry Faces Engine Supply Challenges

The record agreement comes as the global aviation industry continues to grapple with engine shortages, maintenance backlogs, and supply chain disruptions.

Manufacturers have struggled to meet rising demand following the pandemic, while airlines worldwide have experienced delays in engine repairs due to shortages of components and skilled technicians. By investing in its own MRO capabilities alongside the engine order, IndiGo aims to reduce exposure to these industry-wide challenges and improve fleet reliability over the long term. Capital intensity is a running theme across Indian aviation — as seen in the Singapore Airlines fund infusion into Air India.

Looking Ahead

IndiGo’s agreement for more than 1,000 LEAP-1A engines marks a defining moment for both the airline and CFM International. As the largest LEAP engine deal ever signed, it provides IndiGo with the propulsion capacity needed to support its rapidly expanding Airbus A320neo fleet while reinforcing its position as one of the world’s fastest-growing airlines.

The addition of a dedicated engine MRO facility in India further elevates the significance of the agreement. Beyond supporting IndiGo’s operations, the investment is expected to strengthen India’s aviation infrastructure, create high-skilled jobs, and contribute to the country’s ambitions of becoming a regional hub for aircraft maintenance and aerospace services. As air travel demand continues to rise, the deal positions IndiGo to sustain long-term growth while improving operational efficiency and resilience.
