PLATES AND SKIN
1. DESCRIPTION
This section describes the exterior covering of the fuselage which makes up the skin. Also included are the
empennage access panels and belly fire shields.
Serials 1602, 1840, 1863 & subs w/ Air Conditioning: Condenser exhaust/intake screens are installed in
exterior skin below the baggage compartment floor.
A. Fuselage Skin
The fuselage skin is composed primarily of bi-directional E-glass fiberglass with a PVC foam core.
Some areas are of solid laminate construction. Areas around the passenger door are reinforced with
unidirectional fiberglass.
The belly closeout panel is bonded (Serials 0002 thru 0820) or bolted (Serials 0821 & subs) to the
fuselage structure after wing attachment and provides a continuous load path along the bottom of the
fuselage.
