WING PIN MATING BUSHINGS AND WING LOCKING PINS.
NOTE: The wings must be folded in order to perform this inspection. For
the aft mating bushing, inspection can be completed by unlocking
the wing lock and pulling the wing out of the bushing for access.
Ensure the wings are supported to prevent accidental contact with
the ground.
1. Using a rag, clean the six wing pins, six bushings, and four locking pins to remove any foreign
material in the joint. Each wing pin has a mating bushing on the inboard side of the wing joint.
NOTE: The wing pins and bushings are not easily replaceable. Metal shav-
ings in the grease is a symptom of wear that should be monitored
closely for prevention of significant maintenance.
2. Measure the wing pin diameter and bushing bores on both the left and right wings and compare
to the target values in the table below.
3. Visually inspect all wing pins and bushings for wear or damage.
4. Measure the locking pin diameters on both the left and right wings and compare to the target
values in the table below.
