ON LIFTING AND SUPPORTING THE AIRCRAFT
• Check all landing gear components; attach locations, and fasteners for cracks and
any other signs of fatigue. Throughout the inspection of the main landing gear, be
observant for signs of hydraulic fluid leakage from the brake lines or fittings.
• Inspect each landing gear-leg and attach point. Check for evidence of black dust at
the attach points which is an indicator of movement.
• Test the security of each of the landing gear-legs. The landing gear components
may not have any free play in any direction.
• Check that all attach hardware is at proper torque. Remember to account for the
prevailing torque of the nut. If a torque wrench is used on the head of the bolt also
account for the torque to overcome the friction to turn the bolt shank within the
assembly.
• Check the main U-1220 gear legs for corrosion or bubbled paint that may lead to
corrosion.
• Test the security of the brake lines and inspect for signs of wear.
• Grab and shake the wheels and tires to check for bearing looseness.
• Check for smooth, low resistance rotation of each wheel.
• Check for excessive play in both brake calipers.
• Check the brake shoe linings, brake disc and wheel assembly per Matco
manufacturer specifications.
• Use a straight edge to check that each unloaded gear-leg is straight, between the
factory bends.
• Inspect the condition of fasteners and cotter pins at the location of all three wheel
axles.
• Inspect the tires for cracks, wear, and tire pressure, and each valve and valve stem
in good condition, and capped.
