CFM International ships first LEAP-1A engines with RBS to Airbus

CFM International has dispatched the inaugural production LEAP-1A engines equipped with its new reverse bleed system (RBS) to Airbus, anticipating entry into commercial service by mid-year. This new production configuration hardware will also undergo installation in the existing fleet by airlines and overhaul shops. Additionally, CFM plans to introduce the RBS on the LEAP-1B engine.

Certified by the FAA and EASA in 2023, the LEAP-1A engine with the new RBS addresses carbon build-up on fuel nozzles. Consequently, the need for on-wing fuel nozzle replacement and associated maintenance burdens will be significantly reduced. Upon full deployment throughout the fleet, CFM anticipates that fuel nozzle replacement will typically occur during performance restoration shop visits. The hardware, installable on wing in as little as ten hours, is expected to be available in the second quarter of this year.
