SHOULDER HARNESS INERTIA REEL ADJUSTMENT
A shoulder harness with an inertia reel is provided for each front seat occupant and is available (optional)
for all rear seats.
Check the inertia reel mechanism by pulling sharply on the strap and checking that reel will lock in place
under sudden stress. This locking feature prevents the strap from extending and holds occupant in place. Under
normal movement the strap will extend and retract as required. On earlier airplanes provided with a single
strap adjustable shoulder harness located above the side window for each front seat, shoulder strap is routed
over the shoulder adjacent to the window and attached to the lap belt in the general area of occupant’s hip.
Adjust this fixed strap so that all controls are accessible while maintaining adequate restraint for occupant.
Optional shoulder straps are available for rear occupants. Shoulder harnesses should be worn during takeoff,
landing and whenever an inflight emergency situation occurs.
Perform adjustment of inertia reel as follows:
l. Allow harness to wind up on reel as much as possible.
2. On end of the reel, pry off plastic cap over spring. Make sure spring does not come out of plastic cap,
and set cap aside.
3. Unwind harness completely. Measure and mark harness 24 inches from reel center.
4. Wind harness onto reel until the 24 inch is reached. Hold reel and place cap with spring over reel shaft
end.
5. Align slot in shaft with spring tang, wind spring 6 turns + 1/2 turn and snap plastic cover into holes in
reel end shaft.
6. Release harness and, allowing it to wind up, extend harness a few times to check reel for smooth
operation.
7. With reel fully wound, hold with inertia mechanism end up and pry off plastic cap over mechanism
and set reel aside.
8. Install nut in plastic cap so that stud in cap is flush with nut surface, then reposition cap over reel end
and orientating properly, snap in place. Extend harness a few times to make sure action is correct.
