Stowing
Moving the thrust reverser control
lever forward to the STOW position
actuates the stow switch in the throt-
tle quadrant; the following occurs.
n
With the isolation valve powered,
the stow solenoid actuates and
the control valve opens to apply
hydraulic pressure to the stow
ports of the reverser actuators.
n
The actuators start to extend; the
deploy limit switch releases, and
the DEPLOY annunciator extin-
guishes.
n
When the actuators fully extend
to the stow position, the stow
limit switch depresses; the thrust
reverser is fully stowed and
locked.
n
The UNLOCK annunciator
extinguishes.
n
With power removed from the
isolation valve, the control valve
closes and the thrust reverser
hydraulic system depressurizes.
n
The hydraulic system returns to
open center. The ARM and HYD
PRESS ON annunciators extin-
guish.
Emergency Stowing
An Emergency stow switch for each
reverser is located on the cockpit
glareshield and will provide the
same stow sequence (using the alter-
nate 28 volt thrust reverser power
source) as the thrust reverser throttle
levers, in the event of a failure of the
throttle mounted deploy/stow lever,
or of the respective 28 Volt Direct
Current (VDC) bus.
Moving the emergency stow switch
to EMER bypasses the normal sys-
tem and provides an override com-
mand to stow by relaying an
electrical signal directly to the isola-
tion valve, hydraulic bypass valve,
and stow solenoid of the control
valve.
After the reverser stows, the
DEPLOY and UNLOCK annuncia-
tors extinguish; however, the ARM
and HYD PRESS ON annunciators
remain illuminated until the emer-
gency stow switch is moved from
EMER to NORM.
Power to operate the emergency
stow system comes from the oppo-
site system's normal circuit breaker
(i.e., the RH TR CB feeds the left
emergency stow, and the LH TR CB
feeds the right emergency stow).
Preflight Inspection
During preflight inspection, check
the thrust reversers for cracks, dam-
age, and general security. Ensure the
thrust reverser lock-out tools are not
inserted.
In the cockpit, test the system with
the rotary TEST switch on the left
panel. The thrust reverser lights and
the MASTER WARNING annuncia-
tors illuminate with the test switch
positioned to T/REV.
During taxi, deploy the thrust revers-
ers normally. Actuate the emergency
stow switch on both sides and
observe the thrust reversers stow.
Return the thrust reverser levers to
stow and deactivate the emergency
stow switches.
WARNING: Do not attempt
to fly the aircraft if the thrust
reversers fail the preflight test.
S/F TIP
Check each thrust reverser sepa-
rately to check each lever's actuat-
ing microswitches' activation of the
hydraulic system. In the event of a
failed engine, it is possible that the
remaining engine's thrust reverser
could be unusable without the
crew's knowledge because the mal-
function did not manifest itself
when simultaneously checking both
T/R's.
