CABIN
1. DESCRIPTION
This section covers cabin compartment seats, seat harness, trim, cabin headliner, and floor covering.
This airplane has two individual front seats and a split rear bench seat for two passengers. Each front
(crew) seat has a four-point restraint, with inertia-reel retractors on the shoulder belts. The fore and aft
travel path is adjusted through the seat position control located below the center of the seat cushion. The
seat track is angled upward for forward travel so that shorter people will be positioned slightly higher as
they adjust the seat forward. Recline position is controlled through levers located on either side of the seat
back. Rotating the lever to the recline position when there is no pressure on the seat back will return the
seat back to the full up position.
The rear seat features backrests that fold forward independently for each side. Each rear passenger seat
has a fixed seat bottom and a folding seat back.
