The CFM International Leap engine fleet will increase to more than 28,500 active engines in 2032 from just over 6,800 in 2023, according to Aviation Week’s 2023 Commercial Aviation Fleet & MRO Forecast. The increase in fleet and the commensurate utilization are expected to drive MRO spending over the decade to $18.9 billion. That figure includes expenditures from more than 5,700 engine service events.

The Airbus A320neo accounts for the largest Leap fleet, at 52.8%. The Boeing 737 MAX 8 follows at 29.7%.

India is expected to generate 27% of Leap engine MRO demand, followed by Western Europe (25%) and North America (14%).
