IndiGo Signs Record Deal for Over 1,000 LEAP-1A Engines to Power 510 Airbus Aircraft

IndiGo has signed a 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 order in CFM's history. The engines will power 510 Airbus A320neo Family aircraft, strengthening IndiGo's long-term fleet expansion plans as the airline continues to grow its domestic and international operations.

The agreement goes beyond engine procurement and includes CFM's support in establishing IndiGo's upcoming engine Maintenance, Repair and Overhaul (MRO) facility in India, along with a long-term material services agreement aimed at improving fleet reliability and reducing maintenance costs.

IndiGo Places Record LEAP-1A Engine Order

The latest MoU represents the largest engine order ever placed with CFM International for its LEAP-1A engine platform. The engines will be used to power 510 Airbus A320neo Family aircraft, further expanding IndiGo's narrow-body fleet.

The agreement also includes long-term support for spare parts, maintenance planning and material services, helping the airline maintain high aircraft availability while improving operational efficiency.

Partnership Between IndiGo and CFM Continues to Expand

The agreement builds on a long-standing relationship between IndiGo and CFM International, which began in 2016 when the airline operated Airbus A320ceo aircraft powered by CFM56-5B engines.

In 2019, IndiGo selected LEAP-1A engines for its growing Airbus A320neo fleet. Today, the airline operates more than 375 Airbus A320 and A321 Family aircraft powered by CFM engines.

Willie Walsh, Chief Executive Officer Designate at IndiGo, said CFM has been a trusted partner throughout the airline's expansion and noted that the reliability of the LEAP engine supports IndiGo's operational scale and sustainability goals.

Agreement Includes Engine MRO Support

Apart from supplying engines, CFM International will support the development of IndiGo's engine Maintenance, Repair and Overhaul (MRO) facility in India.

The collaboration comes as Safran, one of CFM's parent companies, continues expanding its aerospace presence in India. The company recently inaugurated its largest LEAP engine MRO facility, covering 45,000 square metres, with the capacity to handle up to 300 engine shop visits annually once fully operational.

The MRO partnership is expected to strengthen IndiGo's maintenance capabilities, reduce turnaround times and support its rapidly expanding fleet.

India Becomes a Key Market for LEAP Engines

India has emerged as CFM International's third-largest market, with more than 400 LEAP-powered aircraft currently in service across five Indian airlines. The company also has around 2,000 LEAP engines on order, highlighting the continued growth of India's commercial aviation sector.

H. Lawrence Culp Jr., Chairman and CEO of GE Aerospace, said LEAP engines now deliver up to twice the time on wing in demanding operating environments compared with their initial years of service.

Olivier Andriès, CEO of Safran, said the latest agreement reflects customer confidence in the LEAP engine platform and reaffirmed the company's commitment to investing in India's aerospace manufacturing and MRO ecosystem.

Why the Deal Matters

The agreement supports IndiGo's fleet expansion strategy while strengthening India's aviation infrastructure through local engine maintenance capabilities. As airlines continue to add aircraft to meet rising passenger demand, investments in engine servicing and MRO facilities are expected to play a key role in improving operational efficiency and reducing maintenance costs.

The record engine order also reinforces IndiGo's position as one of the world's fastest-growing airlines and highlights India's increasing importance in the global aviation supply chain.
