Landing Gear Test

Proper operating position of the strut

Extension of an oleo shock strut is measured to determine the

Strut should be removed, disassembled, and inspected.

If a shock strut bottoms after it has been properly serviced, the

Low Fluid

If an aircraft shock strut (air/oil type) bottoms upon initial landing contact, but functions correctly during taxi, the most probable cause is

Inserting, removing, or changing the location of washers or spacers at the center pivotal point of the scissor torque links

If main landing gear wheels have an out-of-tolerance toe-in condition, and this condition is NOT caused by bent or twisted components, it could be repaired by:

Toe-Out

If the extended longitudinal axis of the main landing gear wheel assemblies intersects aft of the aircraft, the wheels can be termed as having
