Aircraft Jack Maintenance & Proof Load Testing

Single-Stage Tripod Jack Procedure

90 Day Maintenance Procedure:

• Check leaks including the following areas of the hydraulic system:
  • – Hydraulic lines (hoses and fittings)
  • – Hand pump (cylinder, fittings and seals)
  • – Reservoir (welds and fittings)
  • – Air operated pump (fittings, air side and oil side seals)
• Inspect the Jack structure for corrosion, bending, cracking and excessive wear in the following areas:
  • – Ball lock pins
  • – Mechanical extension
  • – Welded joints (tripod legs, cylinder and foot pads)
  • – Ram lock nuts (gouge marks and cracks in threads)
  • – Jack pads
• Check fluid levels with rams fully retracted to ensure proper level height
• Visually inspect extended rams for corrosion, foreign matter, excessive wear and leaks around ram seals. Remove any foreign matter.
• Check air operated pump
• Check paint condition and touch-ups where necessary
• Actuate the hand pump and raise the ram to full extension.
• Apply water repellant that is Buna N compatible to the rams (DoAll, RPM, LPS or equivalent)
• Open release valve and verify that rams fully retract
• Lubricate casters (if applicable)

12 Month Proof Load Testing Procedure: complete all of the above including:

• Check hydraulic fluid for contamination (dirt/water) drain and flush if required
• Capacity test (110% of jack’s rated capacity)
