On 10 February 2025, during the MRO Middle East exhibition in Dubai, TARMAC Aerosave signed a contract extension with its partner and shareholder, Safran Aircraft Engines. This renewal defines the conditions for the installation of the reverse bleed system (RBS) on the CFM LEAP-1A engine, carried out by TARMAC Aerosave to support Safran Aircraft Engines’ operations. This marks the second extension of their contract, reinforcing a strong and ongoing partnership.
The RBS system is an exclusive innovation by CFM International for the LEAP-1A and LEAP-1B engines. Designed to mitigate carbon build-up on fuel nozzles, the system reduces the need for on-wing fuel nozzle replacements, thereby lowering maintenance requirements. For customers, this translates into increased operational time and reduced operating costs.
The first RBS-equipped engines were delivered in April 2024. In September 2024, the TARMAC Aerosave “flying team” conducted its first on-wing installation of an engine reverse bleed system (RBS) off-site in Malta. Off-site RBS operations are ongoing.
The TARMAC Aerosave team is fully trained and approved for RBS installation on-wing, near-wing, in-shop, and both on- and off-site. The company has already completed more than 360 CFM LEAP-1A and LEAP-1B events, including Radial Drive Shaft (RDS) changes, with more RBS installations planned in the coming weeks.
Additionally, TARMAC Aerosave’s “flying team” collaborates closely with customers to carry out engine and landing gear changes, both on and off site.
