meet. The flap shims can be changed from the nominal to meet lateral trim tolerances.
SUBTASK 27-51-21-220-006
(1) If you installed a different flap, then adjust the thickness of the shims [65] to the same thickness
as the original flap.
NOTE: The thickness of the shims [65] on the original flap may have been adjusted for lateral
trim per (TASK 27-09-71-820-801).
(a) If you do not know the original thickness of the shims [65], then change the thickness to the
nominal dimension.
NOTE: The nominal thickness of the shims [65] is 0.25 inch (6.35 mm).
