A740C – Aircraft Tool Supply (ATS) 10-Ton Tripod Jack with AT-JPR2 Extension
Available now through the AirParts Aero marketplace.
Overview Section
The Aircraft Tool Supply (ATS) A740C is a heavy-duty, 10-ton hydraulic tripod jack designed for regional jets, turboprops, and heavy business aircraft. Engineered for maximum stability and safety, this jack is a staple for maintenance facilities performing landing gear cycles, tire changes, and structural repairs.
This specific configuration includes the AT-JPR2 Jack Pump Extension, which provides an ergonomic advantage by allowing the operator to stand at a safe distance from the airframe while operating the hydraulic pump. The A740C is known for its "low-profile" start height combined with a significant vertical stroke, making it versatile for a wide range of jacking points on low-wing and high-wing aircraft.
Key Features Section
10-Ton Lifting Capacity: Rated for a maximum load of 20,000 lbs, providing a significant safety margin for most business and regional aircraft.
Stable Tripod Base: Features a wide-stance, three-leg design to prevent tipping, with adjustable leveling feet to ensure a plumb lift on uneven hangar floors.
AT-JPR2 Remote Pump Compatibility: Optimized for use with the ATS pump extension, allowing for high-precision height adjustments while maintaining a clear field of vision of the aircraft jacking point.
Mechanical Safety Lock: Equipped with a threaded safety collar (Lock Nut) that follows the ram as it rises, providing a mechanical fail-safe in the event of a hydraulic pressure loss.
Double-Seal Hydraulic Cylinder: Uses premium aerospace-grade seals to prevent "creep" during long-term storage or extended maintenance procedures.
Foldable Leg Design: Features a modular leg assembly for easier storage and transport when not in use.

Aircraft Compatibility Section
The A740C's height range and 10-ton capacity make it ideal for the following aircraft types found in the AirParts Aero inventory:
Beechcraft King Air 200/300/350: Perfect for dual-main gear lifting and nose gear service.
Bombardier Challenger 600/601/604/605: Rated for the heavy airframe requirements of the Challenger series.
Cessna Citation Excel / XLS / Sovereign: Provides the stability needed for mid-size jet maintenance.
Embraer Phenom 100/300: A versatile tool for light jet fleet operators.
Pilatus PC-12: Offers the reach required for the PC-12’s specific jacking points.
Technical Applications & Safety
Jacking an aircraft is one of the most hazardous tasks in a hangar. The A740C is designed to mitigate risk through its mechanical locking system.1
Safety Warning: NEVER rely solely on hydraulic pressure to hold an aircraft. As the jack is raised, the operator must manually spin the safety lock nut down to the top of the cylinder. In the event of a seal failure, the lock nut will catch the load. Additionally, always ensure the jack is centered on the aircraft's Jack Pad; an off-center lift can cause the jack to "kick out," resulting in catastrophic airframe damage.
Maintenance Insight
The value of the A740C with the AT-JPR2 extension lies in the Hydraulic Control Sensitivity. The remote pump allows the technician to feel the "back-pressure" of the airframe settling, which is vital when leveling an aircraft for weighing or avionics calibration (finding the "Level" flight attitude).
By sourcing this equipment through AirParts Aero, you are investing in a tool designed for serviceability. Unlike "disposable" automotive-grade jacks, the A740C can be fully rebuilt with standard ATS seal kits, ensuring a 20+ year service life in a professional flight department.
Inspection & Maintenance Addendum
Hydraulic Fluid: Use only MIL-H-5606 or AeroShell Fluid 41 (Red) hydraulic oil. Mixing fluids can destroy the seals.
Annual Load Test: It is highly recommended to perform a certified load test annually to verify the integrity of the cylinder and the safety lock threads.
Ram Inspection: Keep the hydraulic ram clean and lightly oiled. Any pitting or scratches on the ram will lead to premature seal failure and hydraulic leaks.
