Products on the platform

• LEAP-1A

  The LEAP-1A is a high-bypass turbofan engine developed by CFM International, a 50/50 joint venture between GE Aerospace and Safran Aircraft Engines (Safran SA). It serves as the successor to the CFM56 series, incorporating ceramic matrix composites and 3D-printed fuel nozzles to improve thermal efficiency and fuel burn. The engine was designed specifically to power the latest generation of narrow-body commercial aircraft, focusing on reduced carbon emissions and noise profiles compared to legacy powerplants. Primary buyers are commercial airlines and global aircraft leasing firms who operate the Airbus A320neo family. It is sold either as part of a direct airframe purchase or through long-term Flight Hour Services agreements. Major operators include Indigo, American Airlines, and EasyJet. The engine competes directly with the Pratt & Whitney PW1100G-JM, maintaining a significant share of the A320neo market due to its conventional architecture and high dispatch reliability. The Garage desk notes that while the engine avoids the geared architecture risks of its competitor, it has faced its own durability challenges in harsh environments, particularly regarding high-pressure turbine shroud degradation. Buyers should verify the current status of service bulletins related to the Reverse Bleed System and monitor the availability of MRO slots, as global shop capacity remains constrained. We would also confirm the specific thrust rating configuration, as this is software-defined to match the specific A320, A321, or A319 airframe requirements.

• LEAP-1B

  The LEAP-1B is a high-bypass turbofan engine produced by CFM International, the long-standing joint venture between GE Aerospace of the United States and Safran Aircraft Engines (Safran S.A.) of France. It represents the successor to the CFM56-7B, incorporating carbon-fibre composite fan blades and Additive Manufacturing (3D-printed) fuel nozzles. This specific model is the exclusive powerplant for the Boeing 737 MAX family, featuring a smaller fan diameter than its sister variants to accommodate the lower ground clearance of the 737 airframe. Procurement is handled through direct sales to airlines and leasing firms, typically bundled with long-term Rate-Per-Flight-Hour (RPFH) service agreements. Major global operators include Southwest Airlines, United Airlines, Ryanair, and Lion Air. The engine is a corner-stone of the narrow-body commercial market, designed to offer a significant double-digit reduction in fuel consumption and CO2 emissions compared to previous generation single-aisle aircraft engines. Buyers must monitor the technical health of the fleet following historical issues related to high-pressure turbine durability and carbon buildup in fuel nozzles. The Aerospace Garage desk would verify the specific hardware standards (Mod Status) of any second-hand unit, as earlier production batches have undergone multiple service bulletin updates. Prospective owners should also confirm the current status of the manufacturer's supply chain, which has previously impacted the delivery schedule of new-build shipsets.
