headrests are provided. The fore and aft travel path is adjusted
through the seat position control located below the forward edge 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 each
side of the seat backs. Depressing the recline release control while
there is no pressure on the seat back will return the seat back to the
full up position.
• Caution •
Do not kneel or stand on the seats. The seat bottoms have an
integral aluminum honeycomb core designed to crush under
impact to absorb downward loads.
To position front seat fore and aft:
1. Lift the position control handle.
2. Slide the seat into position.
3. Release the handle and check that the seat is locked in place.
To adjust recline position:
1. Actuate and hold the seat back control lever.
2. Position the seat back to the desired angle.
3. Release the control lever.
Each rear seat consists of a fixed seat bottom, a folding seat back, and
a headrest. The seat backs can be unlatched from inside the baggage
compartment and folded forward to provide a semi-flat surface for
bulky cargo extending forward from the baggage compartment.
To fold seat back forward:
1. From the baggage access, lift the carpet panel at lower aft edge of
seat to reveal the seat back locking pins (attached to lanyards).
2. Remove the locking pins and fold seat forward.

Seat Belt and Shoulder Harness
Integrated seat belt and shoulder harness assemblies with inertia
reels are provided for the pilot and each passenger. The rear seat
belts are attached to fittings on the floorboard and the forward seat
belts are attached to the seat frame. The shoulder harnesses are
attached to inertia reels mounted in the seat back for the front seats
and on the baggage compartment rear bulkhead for the rear seats.
Each harness is attached to the seat belt. The buckle half of each
assembly is on the left-hand side and the link half is on the right-hand
side. The inertia reels allow complete freedom of movement of the
occupant’s upper torso. In the event of a sudden deceleration, the
reels lock automatically to protect the occupants. It is recommended
that the seat belts be stowed in the latched position when not in use.
An inflatable shoulder harness is integral to each crew seat harness.
The electronic module assembly, mounted below the cabin floor,
contains a crash sensor, battery, and related circuitry to monitor the
deceleration rate of the airplane. In the event of a crash, the sensor
evaluates the crash pulse and sends a signal to an inflator assembly
mounted to the aft seat frame. This signal releases the gas in the
inflator and rapidly inflates the airbag within the shoulder harness
cover, After airbag deployment, the airbag deflates to enable the pilot/
co-pilot to egress the aircraft without obstruction.
The crash sensor’s predetermined deployment threshold does not
allow inadvertent deployment during normal operations, such as hard
landings, strikes on the seat, or random vibration.
• Caution •
No slack may exist between the occupant’s shoulder and
restraint harness shoulder strap.
Stow the seat belts in the latched position when not in use.
To use the restraints:
1. Slip arms behind the harness so that the harness extends over
shoulders.
2. Hold the buckle and firmly insert the link.
3. Grasp the seat belt tabs outboard of the link and buckle and pull to
tighten. Buckle should be centered over hips for maximum comfort
and safety.

4. Restraint harnesses should fit snug against the shoulder with the
lap buckle centered and tightened around the hips.
To release the restraints:
1. Grasp the top of the buckle opposite the link and pull outward. The
link will slip free of buckle.
2. Slip arms from behind the harness.
Cabin Doors
Two large forward hinged doors allow crew and passengers to enter
and exit the cabin. The door handles engage latching pins in the door
frame receptacles at the upper aft and lower aft door perimeter. Gas
charged struts provide assistance in opening the doors and hold the
doors open against gusts. Front seat armrests are integrated with the
doors. A key lock in each door provides security. The cabin door keys
also fit the baggage compartment door lock. Separate keys are
