HYDRAULIC AIRCRAFT JACK PROOF LOAD TESTING MAINTENANCE SCHEDULE

Manufacturers of hydraulic aircraft jacks recommend 90 day maintenance and testing be done on your jack(s) once every 12 months. Testing may also be advised outside of the regular schedule if an event takes places that could potentially damage the jack. For example, being dropped or having something dropped on the jack that may cause damage to the structure or the hydraulic system. Below is an example of maintenance and aircraft jack proof load testing guidelines recommend by most hydraulic aircraft jack manufacturers.

90 DAY PREVENTATIVE MAINTENANCE

CHECK THE HYDRAULIC SYSTEM FOR LEAKS

CHECK THE JACK STRUCTURE FOR CORROSION, BENDING, CRACING, EXCESSIVE WEAR, ETC.

CHECK FLUID LEVELS WITH RAMS FULLY RETRACTED

EXTEND RAMS TO VISUALLY INSPECT FOR CORROSION, FOREIGN MATTER, EXCESSIVE WEAR OR LEAKS AROUND THE SEAL

CHECK PAINT CONDITION AND TOUCH UP ANY EXPOSED AREAS

ACTUATE THE HAND PUMP AND RAISE THE RAM TO FULL EXTENSION AT LEAST ONCE

APPLY DOALL, RPM, LPS OR EQUIVALENT WATER REPELLENT THAT IS BUNA N COMPATIBLE TO THE RAMS

OPEN THE RELEASE VALVE AND VERIFY THAT RAMS FULLY RETRACT

LUBRICATE CASTERS

It is possible for all of the above maintenance to be done without the assistance of the manufacturer or a third party service provider. The only difference is that if you do it yourself the maintenance will not be certified, which may or may not meet your internal or external compliance mandates.
