Douglas DC-9 Aircraft Accessory Maintenance Services
Introduced in 1965, the Douglas DC-9 revolutionized short-haul aviation by offering jet performance with operating economics suitable for routes previously served only by turboprops. The DC-9's rear-mounted engines, T-tail configuration, and airstairs enabled operations from smaller airports without ground equipment. While original DC-9s have largely retired, the design evolved through the MD-80/90 series and Boeing 717, with some aircraft still in cargo and specialized service.
Four Star Accessory Overhaul provides comprehensive DC-9 aircraft accessory maintenance services for operators maintaining these classic jets in continued service. Our capabilities span hydraulic systems, pneumatic components, power generation units, electromechanical accessories, fuel system components, with specialized focus on obsolescence management as OEM support for this out-of-production platform diminishes.
Our FAA and EASA certifications enable seamless service for DC-9 aircraft regardless of registration, supporting cargo and specialized operators with the obsolescence solutions and precision machining capabilities that aging legacy aircraft require. Our ability to manufacture unavailable parts ensures continued DC-9 operations where OEM support is limited or has ended.
