Airframe heavy maintenance programmes

ST Engineering Aerospace provides comprehensive airframe heavy maintenance services, involving deep structural inspections, corrosion control, and complex component overhauls. This programme covers C-checks and D-checks for a wide range of commercial aircraft, originating from the company's long-standing position as the world's largest independent airframe maintenance, repair, and overhaul (MRO) provider by man-hours. Work is conducted across a global network of hangars, including major facilities in Singapore and various international outstations. The service is sold primarily through long-term maintenance agreements and ad-hoc contracts to commercial airlines, air cargo carriers, and aircraft leasing firms. Notable operators known to have utilised these services include Singapore Airlines, FedEx Express, and various global leasing entities. The programme is often bundled with passenger-to-freighter conversions or cabin interior refurbishments, providing a single-site solution for major airframe life-extension projects. Key risks involve potential capacity constraints during peak industry demand cycles and the logistical complexity of managing global spares supply chains. The Aerospace Garage desk would verify the specific regulatory certifications held by individual regional facilities, such as those from the Civil Aviation Authority of Singapore or the Federal Aviation Administration. Verification of current hangar occupancy and the specific aircraft types serviced at each geographic location is also recommended.
