Strategic Partnership Framework and Contractual Details

The agreement between HAECO and Brussels Airlines is structured to maximize operational efficiency and flexibility for both parties. Commencing in September 2025 and running through 2028, HAECO Hong Kong will provide C-checks (including C1 and C2) and six-year inspections for Brussels Airlines’ entire fleet of 10 Airbus A330-300 aircraft. These checks are among the most thorough in the industry, requiring each aircraft to undergo detailed inspections, part replacements, and system overhauls, ensuring continued airworthiness and safety.

The maintenance will take place at HAECO’s 22-bay hangar at Hong Kong International Airport, one of the largest and most advanced in the Asia-Pacific region.
