Forward Covers

Several covers are installed in the forward fuselage to protect fuel lines, cover the electric fuel boost pump and direct cabin heat. These are removable for maintenance.

I fit the F-982E Access Plate and F-982D Heat Baffle to the F-782C Center Cabin Cover. I then riveted the baffle the necessary nut plates to F-782C.

I inserted the F-782C between the center floor reinforcement angles and the F-601N vertical angles on the firewall. I checked to make sure an even amount of the horizontal section of F-782C was exposed above the floor angles. I had to be careful not to force it down too far as the flanges would be forced inboard by the radius of the angles and a poor fit would result. I used a simple wood spacer between the cabin floor and the center cabin cover to ensure that this wouldn’t happen.

I riveted the nutplates to the F-983A Fuel Valve Plate and screwed it to the F-704 bulkhead. I the slid the F-983C Fuel Valve Cover underneath the plate and fastened it to the F-783B cover support ribs and the fuel valve plate.

I adjusted the F-782C fore/aft until it mated with the bottom of the F-983C, Fuel Valve Cover and clecoed the two parts together.

I fit the forward section of the F-782C to the firewall and F-601K-1 firewall recess. I rechecked the height of the F-782C and drilled it to the floor stiffener angles and finished drilling it to the firewall as well.

I removed the fuel valve cover and center cabin cover components and installed the necessary nutplates. As I am installing electric elevator trim, the triangular flange on top of the F-983A could be trimmed away.

Time: 12 hours.
