Liebherr-Aerospace and HAECO Landing Gear Services have completed what they describe as the world’s first major landing gear overhaul for the COMAC C909 regional jet, providing a maintenance benchmark for the type as its in-service fleet grows.
The work was carried out jointly under an existing collaboration between the two companies, with Liebherr-Aerospace as the original equipment manufacturer for the landing gear system and HAECO responsible for overhaul execution at its landing gear facilities. The project involved a full teardown, inspection, repair and reassembly of the C909 landing gear set in accordance with the OEM’s maintenance specifications.
According to the companies, the completed overhaul is intended to support operators of the C909 in China and Southeast Asia by establishing an industrial process for repeat events and by securing access to OEM-backed repair and overhaul capability. It also builds on a broader component maintenance agreement between HAECO and Liebherr-Aerospace that covers hydraulic and landing gear services for COMAC’s C909 and C919 aircraft families.
