Safran is preparing to certify a new high-pressure turbine (HPT) hardware durability kit for the CFM International LEAP-1B engines, which power the Boeing 737 MAX aircraft family. This development follows the certification of a similar upgrade for the LEAP-1A engines used in the Airbus A320neo family. According to Safran executives, this certification is expected to occur in 2025.
During Safran's Q4 2024 earnings call, CEO Olivier Andries stated that "we expect the certification of the new blade to occur within the year, within 2025." The company did not provide updates on another component, the reverse bleed system (RBS), for the LEAP-1B. This system was first certified for the LEAP-1A in April 2024 and has been retrofitted since mid-2024 to reduce carbon build-up on fuel nozzles.
Gaël Méheust, President and CEO of CFM International, emphasized that "the requirement for on-wing fuel nozzle replacement and associated maintenance burden will be dramatically reduced" with full deployment of these systems.
