Line Maintenance
Round-the-clock line maintenance across 18 airports in Hong Kong and Mainland China, serving more than 140 airlines and 200,000 flight movements annually.
HAECO Line Maintenance is a continuous-operation ground-support service delivered at Hong Kong International Airport and 17 stations across Mainland China — from Beijing and Shanghai to Chengdu, Shenzhen, and Zhengzhou. The service covers the full daily-ops maintenance envelope: routine transit checks with Certificate of Release to Service (CRS), overnight and scheduled A-checks, engine on-wing servicing, cabin cleaning, cabin interior management, ramp support, and full AOG recovery.
The service is designed for airlines operating into congested hub and point-of-entry airports where turnaround slots are tight and any unplanned ground time erodes network reliability. HAECO holds regulatory approvals from 16 civil aviation authorities spanning Asia-Pacific, Africa, the United States, the European Union, and the Middle East, enabling CRS issue against a wide range of international registrations without ferry or regulatory delay.
For procurement teams, the differentiating factor is scale combined with network density. Handling approximately 200,000 flight movements per year across a single coordinated network means HAECO can resource-share between adjacent stations, carry pooled spares, and mobilise AOG teams at short notice — capabilities that a single-station independent provider cannot replicate. Coverage extends to both narrowbody types (including the A320 family and A321neo) and widebody long-haul jets (B777, A330, A350), making it viable as a single-vendor line maintenance partner for mixed-fleet operators.
For GCC airlines and Gulf-routed carriers with significant Asia-Pacific footprints, HAECO's positioning at Hong Kong — one of the busiest cargo and passenger hubs in the region — makes it a natural choice for aircraft cycling through East Asia.
