(5) Do a check of the clearances at the mid spar attach fittings (Fig. 401, Detail D).
(a)
Make sure the distance between the face of the wing fitting bushing and the mid spar fitting is 0.020-0.060 inch (0.508-1.524 mm). 1) It is permitted to have a maximum difference of 0.005 inch
(0.127 mm) between the left and right sides of the strut.
(b)
Make sure that the clearance (mid spar fitting to wing fitting) adjacent to the head end of the fuse pin (outboard side) of both the left side fitting and the right side fitting is between 0.020-0.060 inch (0.50-1.52 mm). 1) The gap on the left side fitting must be within 0.005 of
the same gap on the opposite (right side) fitting.
(c)
Make sure the clearance adjacent to the nut end of the fuse bolt is between 0.020-0.105 inch (0.50-2.67 mm).
(d)
If the clearances are more than the limits, replace the applicable side link assembly.
