Tackling LEAP issues

Oman Air’s Boeing 737 MAX A40-MA powered by CFM56 engines.

IN PART because CFM is used to manufacturing and delivering very large numbers of engines annually (CFM56 deliveries in 2017 totalled 1,444 and LEAP deliveries totalled 459), its production ramp-up for the LEAP engine is even larger-scale than Pratt & Whitney’s ramp-up for the PW1000G. CFM expects to nearly triple to about 1,200 engines the LEAP production rate this year and is planning to be able to deliver 2,000 to 2,200 LEAPs annually by 2020. By then CFM56 production will have fallen to a long-term residual rate, CFM only manufacturing new CFM56s as spare engines and as powerplants for the 737-800-based Boeing P-8A Poseidon maritime surveillance aircraft programme.
