3. ON-AIRCRAFT MAIN WHEELS INSPECTION
CAUTION
Whenever a maximum energy Rejected Take Off (RTO) has
occurred the intrinsic heat buildup can be quite severe and the
components are to be inspected and, if required, overhauled in
accordance with the procedures addressed on the Component
Maintenance Manual (CMM): Parker Cleveland P/N
AWBCMM0001-7, last issue.
On-aircraft maintenance of wheel assemblies is limited to inspection of wheel and brake
assemblies.
Perform on-aircraft inspection as follows:
(1) Remove wheel dust cover and visually inspect the wheels for corrosion, cracks, or
other visible damage.
(2) Check wheel nuts to be sure they are properly installed and have not worked loose.
Bolt threads should be flush to 1-1/2 threads extending beyond the nut.
(3) Visually inspect tyres for cuts, flat spots, and tread or sidewall damage.
(4) Check inflation pressure. Proper inflation will provide maximum tyre and wheel life.
(5) Pressure must be checked when tyres are cool.
(6) Inspect the brake disc for rust, excessive grooves, large cracks, or other visible
damage.
(7) Visually inspect the brake cylinder for corrosion, cracks, or other visible damage.
Check inlet fitting bosses and anchor bolt lugs for cracks.
(8) Check back plate attachment bolts to insure they are properly torqued and have not
worked loose. Gaps between the back plate and cylinder would be evidence of this.
(9) Check fit of brake cylinder anchor bolts in torque plate bushings for sloppiness. This
can be accomplished by grasping the cylinder and moving it; slight movement is
normal. Excessive movement is cause for removal and detailed inspection.
(10) Linings should be visually checked for extreme chipping on the edges. Lining
featuring a thickness of 0.100 inch (2.54 mm) must be replaced.
(11) Visually check torque plate for corrosion, cracks, loose anchor bolt bushings, or
other visible damage. Anchor bolt bushings must be flat against torque plate surface.
(12) Check for any brake fluid leaks. Linings which have been contaminated with fluid
should be replaced.
(13) If the slippage marks are not in alignment, a detailed inspection must be made, the
reason determined, and if necessary, the condition corrected before the next flight.
