10 EASY STEPS FOR EFFICIENT AIRCRAFT JACK MAINTENANCE

10 EASY STEPS FOR EFFICIENT AIRCRAFT JACK MAINTENANCE

It is important to frequently calibrate, and proof load test your aircraft jack. But, it is also just as equally important to maintain it. Proper maintenance and care of an aircraft jack can make all the difference in the world. With efficient aircraft jack maintenance, the lifespan of an aircraft jack can be extended and the possibility of damage, due to negligence, can be eliminated.

Below, we have created a small guide on what procedures should be taken to ensure your aircraft jack is properly being cared for and maintained.

AIRCRAFT JACK MAINTENANCE PROCEDURE

Aircraft jack maintenance procedures should be performed regularly. Most procedures should be done every 90 days.

FREQUENT TIGHTENING

One of the main causes of aircraft jack damage stems from lack of part tightening. For example, an aircraft jack’s cylinder can easily become damaged if the bushings are not tightened frequently. With proper tightening procedures, the likelihood of damage decreases significantly. Parts of an aircraft jack should be tightened, or at least checked for tightness, after each use.

INSPECT AIRCRAFT JACK STRUCTURE

One of the most important parts of maintaining an aircraft jack is ensuring that the structure is in solid condition. Frequent inspections of the structure help to ensure that it is free of corrosion, bending, cracking and excessive wear. When expecting the aircraft jack structure, it is important to look at the following areas:

  • Base plate
  • Hydraulic Cylinder Assembly
  • Mechanical extensions
  • Jack Pads, Nose and Main Adapters
  • Retaining Ring
  • Spacer Blocks
LEAK CHECKS

Checking an aircraft jack for leaks regularly is another great way to maintain your jack. When checking the aircraft jack for a leak, it is important to be sure to check the hydraulic system as well. This includes the hand pump (cylinder, fitting and seals) and the reservoir (welds and fittings).

FLUID LEVEL CHECKS

When checking for leaks, it’s also important to look at the fluid levels. When checking an aircraft jack’s fluid levels, its vital to ensure that the rams are fully retracted to be sure the fluid level height is correct.

INSPECT RAMS

Visually inspecting rams when extended is vital to ensure your aircraft jack is in tip-top condition and stays that way. When inspecting the extended rams, it’s important to look for corrosion, foreign matter, excessive wear and leaks around the ram seals. If foreign matter is found during inspection of the rams, it’s important to remove it right away to ensure there is no damage.

PAINT CONDITION CHECKS

Part of properly maintaining your aircraft jack is ensuring that the outside structure is up to par. Paint conditions of the aircraft jack should be inspected frequently and touched-up if chipped.

APPLICATION OF WATER REPELLENT

Applying water repellent to your aircraft jack can guarantee a longer lifespan and decrease damage, such as rush. Repellant that is Buna N compatible to the rams should be used (DoAll, RPM, LPS or equivalent).

INSPECTION OF MOVEMENTS

Part movements on an aircraft jack should be smooth. To properly maintain your aircraft jack, it is vital to check the movements of the following part as follows:

  • Actuate the hand pump
  • Raise ram to full extension
  • Open release valve
FLUID CONTAMINATION CHECK

Fluid maintenance is crucial for proper operation of an aircraft jack. Hydraulic fluid needs to be checked for contamination. If contaminated, the fluid needs to be drained and flushed. This procedure doesn’t have to be done every 90 days but should be performed every 12 months.

PROOF LOAD TESTING

Aircraft jack proof load testing should be done annually to ensure that an aircraft jack is accurate and reliable.

USING ON-SITE MAINTENANCE

Another great way to maintain your aircraft jack is to have routine maintenance and calibration performed. Sending your jack out for these services can be costly,time consuming and result in a lot of downtime; therefore, an efficient way to save money and time is to find a lab that can perform onsite aircraft jack maintenance. At e2b calibration, we perform all onsite aviation maintenance and calibration services, including aircraft jack maintenance and care, at the customer’s location. If you have any questions about onsite calibration services, contact e2b calibration. Our technicians are available to answer any question you may have and to guide you through the on-site process.
