Willis Lease Finance Corporation has booked up to 60 CFM International LEAP engines, including both LEAP-1A and LEAP-1B on firm and option orders. According to list prices, the deal is worth nearly $900 million.

In a statement the leasing specialist said that newly-acquired powerplants will be used to “support its customers operating Airbus A320neo and Boeing 737 MAX aircraft”.

The deliveries are set to begin already in 2020, supplementing the eight LEAP engines Willis currently owns.
