Seat Removal and Installation
Before entering the cockpit, ensure that all seat
and canopy safety pins and devices are properly
installed. Check that the ejection control safety
handle (fig. 6-13) (head knocker) is in the down
and locked position. Ensure that the pilot’s and
copilot’s eject mode selector handles are set to the
SELF EJECT position.
Remove the parachute and survival kit by
disconnecting the oxygen and communications
quick-disconnect. Disconnect the emergency
oxygen and emergency radio beacon quick-release
lanyard attached to the aircraft’s structure.
Squeeze the harness release handle and disengage
from holder. Remove the parachute actuator
arming cable from the handle, and pull upward
on the handle until the harness release actuator
locks in the MANUAL DETENT position. Reseat
the handle into the holder.
Withdraw the inertia reel straps from the chute
roller fittings. Rotate the aft end of the survival
kit up and forward to release the forward
mounting hooks from the seat mounting brackets.
Remove the parachute and survival kit from the
aircraft and deliver to the aviators equipment
work center.
If the seat is not in the full down position,
apply electrical power and lower the seat to the
full down position. Do not hold the seat adjust
switch in the UP or DOWN position for more
than 15 seconds to prevent damage to the seat
height actuator.
Remove the M99 initiator actuating cover and
install safety pins in the initiators (fig. 6-5). The
pilot and copilot seats require two safety pins, and
the TACCO and SENSO seats require one safety
pin. Remove, as required, overhead window or
hatch assembly. Remove cover from top of the
