3. Measure the inner diameter of the flap hinge and wing hinge bushings, using a gage pin or caliper.
If they are greater than .0195” replace as necessary using the following steps:
a. Extend the flaps to 30°.
b. Remove the AN4C13A bolt, MS21043-4 nut and two NAS1149C0432R washers that attach
the flap pushrod to the flap surface of the affected flap.
c. Remove the hinge pins and 95630A460 PTFE washers from all three hinges of the
affected flap.
d. Remove the flap from the wing. (See “Flap Surface Removal” on page 17-19.)
e. Press out the damaged bushing(s).
f. Prepare the new bushings by first soaking in isoproply alcohol, then lightly scuffing bonding

VERIFICATION METHOD:
Record results and check that wear is within these limits.
• Maximum system free play = .020” radially
• Minimum flap pin diameter = .175”
• Maximum flap bushing diameter (wing hinges and flap hinges) = .195”
Inspect the flap system for proper function. (See “Inspect Flap Rigging” on page 9-65.)
