HAECO Cathay support for Boeing 777 landing gear will continue under the companies’ extended maintenance relationship, the Hong Kong aircraft engineering group announced on Oct. 14. HAECO Landing Gear Services in Xiamen is set to provide exchange and overhaul services for the airline’s Boeing 777-300ER aircraft.
The announcement concerns specialized support for an existing long-haul fleet, not the purchase of additional Boeing 777 aircraft. Maintenance agreements can be important to fleet reliability without changing an airline’s route map or aircraft orderbook. HAECO did not attach a publicly disclosed contract value or a definitive end date to the latest statement.
HAECO and Cathay have collaborated for decades. The maintenance provider said their broader corporate relationship began in 1950, while landing gear work dates to 2010. Those milestones are a statement of partnership history and should not be confused with the date of this latest support announcement.

HAECO Cathay Support Covers Boeing 777-300ER Components
The new statement identifies gear exchange and overhaul work for the Boeing 777-300ER. Landing gear systems experience demanding operating cycles during ground handling, takeoff and landing, and they are subject to defined inspection and maintenance requirements. Overhaul work is a specialized shop process rather than a routine flight-line inspection.
An exchange arrangement can allow an operator to use a serviceable component while another unit goes through its maintenance cycle. Such arrangements help coordinate spare equipment, workshop capacity and aircraft maintenance schedules. They do not remove the need for approved procedures or the operator’s own airworthiness responsibilities.
HAECO’s Xiamen facility is the specified provider. The company lists its broader landing gear support capability across several Boeing, Airbus and Embraer aircraft families, but the latest Cathay statement names Boeing 777-300ER work in particular. It should not be presented as a new deal for every aircraft type HAECO can service.
The company’s Oct. 14 release says the work is intended to support reliability and performance. The release does not quantify how many future gear sets will be processed annually or guarantee a change in flight punctuality.
A Maintenance Relationship Built Across Aircraft Generations
HAECO said the gear partnership started in 2010 when its Xiamen operation completed its first Boeing 747 landing gear overhaul for the airline. Since then, the supported fleet has included the Boeing 747-400, 747-400ERF, 777-300 and 777-300ER.
Across that period the company reports more than 200 landing gear deliveries. That cumulative number spans its historical support activity and should not be represented as 200 gear sets delivered under the October 2026 announcement alone.
Cathay’s long-haul operations make widebody maintenance planning consequential. Airlines need to align heavy component shop visits with aircraft availability, utilization and spare inventories. Outsourced maintenance work can add specialist capacity, but the details of any fleet-wide planning arrangement are not in the public release.
Similar service announcements often receive less attention than route launches, yet they describe the infrastructure that keeps aircraft usable. Readers seeking wider industry context can consult The Aviation Diary’s commercial aviation coverage.
What the Agreement Does Not Establish
HAECO has not published the number of future landing gear exchanges, a transaction price or a fixed annual maintenance schedule associated with this continuation. As a result, claims about exact revenue, cost savings or improvements in airline on-time performance cannot be supported from the announcement.
The company also did not announce that maintenance work has moved from an existing location to a new one. Xiamen is part of the established relationship. The material development is continued support for the Boeing 777-300ER fleet, with a defined focus on landing gear overhaul and exchange.
The Oct. 14 statement confirms a continuing industrial relationship; assessing operational results will require later evidence, such as completed maintenance work or airline-reported performance data. Those are different from the supplier’s expectations at the time an agreement is announced.
