five-point restraint systems and seat cushions,
single or dual pilot main instrument panel,

A. Crew Seats
(Ref. Figure 1)
The crew seats are interchangeable, with fore
and aft adjustment, automatic tilting mecha­
nism and energy attenuating structure,
five-point restraint system, and upper and
lower seat cushions.
The crew seats are located in the crew
compartment. The pilot seat is located on the
right side of the crew compartment, the
co-pilot seat is located on the left. Each seat
will comfortably accommodate an occupant
ranging from a 25th percentile woman to a
95th percentile man.
The seat structures attach to the crew
compartment floor and subfloor structure.
Each crew seat has a combined vertical and
horizontal fore and aft adjustment of 3 inches,
with seven positions . The seat adjustment
controls are located at the center of the seat.
During fore and aft adjustment of the seat, the
automatic tilting feature tilts the seat back
from 18 degrees in the fore most position, to 20
degrees in the rear most position.
The seat assemblies are comprised of a formed
tubular structure, sheet metal seat pan with
removeable cushion, and a fabric seat back
with cushion. Incorporated in the frame are
energy absorbers that initiate stroking of the
seat when severe vertical loads are applied to
the seat assembly. Because of this feature,
No
stowage under seats is allowed. Each crew
seat has a minimum available stroking
distance of 7 inches.
B. Five − Point Restraint System
The crew seats are equipped with a five-point
restraint system that combines a lap safety
belt, tie-down strap and double strap shoulder
harness with a manual locking inertia reel.
The restraint straps are fabricated from
polyester webbing with sewn in buckles and
attach fittings.
The inertia reel also provides the pilot or
copilot with the ability to manually lock the
inertia reel. The inertia reel lock handle can be
moved to release the reel and provide free
movement of the shoulder harness. An
adjuster on each shoulder harness permits the
pilot or copilot to adjust the tension of the
shoulder harness. The lap belts also have an
adjustment feature.
C. Seat Cushions
Each crew seat is equipped with a seat back
and seat pan cushion. The seat materials
comply with FAR 29.853 (B) vertical burn
requirements. Velcro strips secure the seat
cushions to the seat pan. The seat back
cushion is incorporated into the seat back
fabric and is secured with a laced cord.
