MAIN
1. Aft Wing Attach Fittings 100 Hour Inspection
A. Background
Should the seals for the windows and doors not be maintained, leaks may develop which, if not
corrected, will allow an ingress of water. This water contamination will wet the insulation around the
aft wing attach fittings creating a highly corrosive environment.
B. Procedure
Each 100 hours, inspect to determine condition of the aircraft window and door seals, the condition
of the aft wing attach fittings, the insulation material around the affected area, and the drain holes in
the bottom fuselage skin at the aft attach fittings area.
(1) Gain access to the left and right aft wing attach fittings.(See Figure 1.)
(a) Remove rear seats and the rear floorboard.
(b) Remove interior mouldings and carpet as necessary.
(c) Remove the carpet from the baggage area floor and remove the two access panels in the
baggage area floor.
