McDonnell Douglas aircraft remain in active service across cargo fleets, charter and government operators, and select international passenger carriers decades after the company merged with Boeing in 1997. Tronair manufactures McDonnell Douglas ground support equipment for the commercial lineup that carries the heritage badge, including the DC-8 Series 60, the DC-9 narrowbody family (Series 10 through Series 50), the DC-10 widebody, the MD-11 widebody freighter, the MD-88, and the MD-90. Cargo airlines, FBOs handling diversion and freighter traffic, ground handling companies serving secondary stations, and operators keeping legacy commercial platforms in revenue service rely on Tronair for McDonnell Douglas aircraft GSE parts and tooling.

Though McDonnell Douglas was absorbed into Boeing in 1997, its commercial airframes continue to fly long-haul cargo routes, regional freight networks, select passenger services, and government missions decades after the merger. The MD-11 freighter remains a backbone of long-haul cargo for carriers including FedEx Express. The DC-10 continues in cargo and tanker roles globally. The DC-9 family operates with regional cargo carriers and government fleets. The MD-88 and MD-90 remain active with niche operators worldwide, and the DC-8 Series 60 continues in cargo and special-mission service.
Supporting these airframes long after their production lines closed means producing McDonnell Douglas servicing and maintenance equipment to original specifications. Tronair has spent nearly 50 years doing exactly that. ISO 9001:2015-certified manufacturing, OEM-spec engineering, deep parts inventory, and our broader family of brands give operators long-term confidence in their GSE.
Tronair's program for McDonnell Douglas platforms spans commercial cargo, charter, and select passenger operations. The categories below outline the equipment most relevant to operators of these airframes.
Towing an MD-11 freighter at maximum taxi weight or repositioning a DC-10 in tight ramp conditions requires towbars rated for substantial loads. Tronair manufactures heavy-duty towbars with welded steel construction, ball lok-T pin locking, durable powder-coat finishes, and integrated shear protection. Interchangeable heads support multiple McDonnell Douglas variants from a common towbar inventory.
Columbus Jack, part of the Tronair family, produces tripod jacks rated up to 30 tons and beyond for widebody and narrowbody lift work. For MD-11 wheel and brake servicing, DC-10 landing gear inspections, DC-9 maintenance, or MD-90 structural access, our jacks are specified to the exact airframe load ratings and jack point geometries required.
Tronair HPUs supply calibrated pressure and flow output for hydraulic system testing across the McDonnell Douglas commercial lineup. Flight control rigging, landing gear cycling, and component actuation can all be performed without engine operation, which matters especially in high-tempo cargo turnarounds where APU run time is operationally costly.
McDonnell Douglas commercial aircraft span several electrical architectures, from the conventional 115/200 VAC 400 Hz systems on the DC-9 and DC-10 to the configurations on the MD-88 and MD-90. Tronair GPUs are configured to match the voltage, frequency, current capacity, and power-quality requirements of each airframe, supporting safe pre-flight checks and avionics work.
Hydraulic fluid management, engine oil servicing, lubricant transfer, and contamination control all require purpose-built service carts. Tronair fluid service carts feature baffled dual-reservoir construction, vacuum degassing, and air-operated pumps. McDonnell Douglas operators integrating these carts into existing cargo or passenger maintenance workflows benefit from inlet connections for shop air and external nitrogen.
From cabin oxygen replenishment on MD-11 and DC-10 passenger configurations to nitrogen strut and accumulator charging across the DC-9 family and the MD-88 and MD-90, Tronair specialty servicing carts cover the full range of gaseous system work. Booster pumps and regulated manifolds support efficient line operations under strict pressure control.
Cargo airlines flying MD-11 and DC-10 freighters, ground handlers supporting MD-88 and MD-90 ramp operations, FBOs serving legacy DC-9 and DC-8 Series 60 traffic, and government customers maintaining heritage McDonnell Douglas fleets all benefit from a single, OEM-spec source for their GSE. Operators looking to buy McDonnell Douglas servicing equipment can work through Tronair's sales engineers to scope a package against the specific airframe mix, facility layout, operational tempo, and procurement timeline involved.

Yes. A small population of DC-8 Series 60 freighters remains in cargo and special-mission service. Tronair's catalog includes towbars, jacks, and servicing equipment specified to the DC-8 Series 60 airframe, supporting operators keeping these classic widebodies operational.
Operators running MD-11 freighters at hub airports benefit from heavy-duty multi-head towbars, dedicated widebody tripod jacks, high-output GPUs sized for 400 Hz aircraft loads, and fluid service carts that match the hub's turnaround pace. Tronair sales engineers regularly scope packages for cargo terminals running fleets of MD-11s alongside other widebody freighters.
