d. Check the general condition of each limit switch and its actuator, and wiring for fraying, poor
connections or conditions that may lead to failures.
e.
Check the side brace link through center travel by attaching the upper and lower links, setting them on
a surface table and ascertaining that when the stop surfaces of the two links touch, linkage is not less
than .062 nor more than .125 of an inch through center. Should the distance exceed the required
through center travel and bolt and bushings are tight, replace one or both links.
f.
With the side brace links assembled and checked, ascertain that when the stop surfaces of the two links
contact, the clearance between each downlock hook and the flat of the downlock pin is not less than
0.010 of an inch. Should clearance be less than that required, the hook only may be filed not to exceed
a gap of more than 0.02S of an inch. The maximum allowable clearance between each hook and the
downlock pin that are service worn is 0.055 of an inch. Should clearance be more than 0.055 of an
inch, replace the pin, check clearance and then if still beyond tolerance, replace hooks. The gap
between each hook should be equal.
g. Repair of the landing gear is limited to reconditioning of parts such as replacing components, bearings
and bushings, smoothing out minor nicks and scratches and repainting areas where paint has chipped
or peeled.
