Cabin Safety Equipment

Passenger Restraints
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.
Serials 0002 through 1499, 1501 through 1519 after SB 2X-25-14 and
serials 1500, 1520 and subsequent; 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.
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.
