seal depressors mounted on the strut.
The lower bulb-seal are mounted in retainer tracks on the inner
surface of the lower bifurcation wall on the left half. These fire
seals contact seal depressors mounted on the right half.
A bulb type fire/aerodynamic seal is mounted around the
circumference of the inner wall, aft of the inner wall v-blade. The
circumferential bulb-seal fire seals contact the engine case.
Physical Description
The rubber fire seals are constructed from a silicone rubber that
is reinforced with fabric layers. The rubber fire seals are bulbseals
that have a circular cross-section and foot that fits in a
metal seal retainer track. The bulb-seals can be hollow or can
be filled in some segments with a sponge foam to prevent
collapse of the seal where the seal fits in small radius curvature
turns. The rubber fire seals are also molded into specific
shapes for some areas.

General
Each T/R translating sleeve has two deactivation points. You
install two pins at these points to deactivate the T/R for airplane
dispatch.
Each translating sleeve has two holes at the deactivation points.
Rubber plugs are usually in these holes. You remove these
plugs before you install the pins. The pins are usually in the fly
away kit.
The pins mechanically connect the translating sleeve structure
to the stable cascade support ring. This prevents the movement
of the T/R sleeve.
Be sure to follow the thrust reverser deactivation for flight
dispatch procedure found in the airplane maintenance manual
(AMM).

General
The thrust reverser control system controls hydraulic power
and electrical power to deploy and stow the thrust reverser (T/
R) translating sleeves. The system uses 24/28v dc electrical
power and reverse thrust lever position for control.
You can deploy the thrust reversers when the airplane is less
than 10 feet (3 meters) from the ground. The flight control
computers (FCC) and a radio altimeter operated relay supply
