Brief Description: Install the WD-657 external steps
Remove the F960 Rear Baggage side wall. The baggage floor is already removed (used plate-nuts to attach). Cut a 1 1/2" diameter hole in the fuselage side skin using the already drilled pilot hole. Trim away the flanges of the F-923 rib and cut hole in the web of the F-925 rib using a fluted hole cutter. Insert the WD-657 step and adjust the hole in the floor rib to make sure the flat plate of the WD-657 fits flush with the fuselage skin. Go through this process for both sides.
