12.10.3.21.5. Compress the strut by any means possible such as the use of a ―J‖ bar,
chocks, milk stool or taxiing the aircraft onto shoring in order to elevate the flat tire.
12.10.3.21.6. When the strut has been compressed to the maximum extent possible,
tighten the tiedown device.
12.10.3.21.7. Remove the flat tire if time and situation permits.
12.10.3.21.8. Flight should be made with the landing gear extended and the landing
gear control circuit breaker pulled. When safely airborne, pull the touchdown relay
circuit breaker. Refer to the flight manual for airspeed limitations with landing gear
extended. After landing, reset the touchdown relay circuit breaker.
12.10.3.22. Failed Engine Driven Hydraulic Pump
12.10.3.22.1. Disconnect the failed engine driven hydraulic pump from the gearbox
and secure to any available structure with safety wire. Do not disconnect hydraulic
lines.
12.10.3.22.2. Install a starter pad in place of the failed hydraulic pump.
12.10.3.22.3. If time and resources permit, the pump may be removed from the
nacelle as follows:
12.10.3.22.3.1. With the ESS DC bus powered, place the corresponding hydraulic
pump switch to the OFF position. This will close the hydraulic shutoff valve.
12.10.3.22.3.2. Disconnect and plug all hydraulic lines to the pump.
12.10.3.22.3.3. Remove the failed pump and install a starter pad in its place.
CAUTION: The hydraulic pump switch must remain in the OFF position as long
as the hydraulic pump is removed.
12.10.3.23. Failed Fuel Valve(s)
12.10.3.23.1. Locate the failed valve(s) and remove the cannon plug(s).
12.10.3.23.2. Manually open or close the valve(s) by actuating the manual arm.
NOTE: On some aircraft, the dump mast shutoff valves must be manually closed to
refuel. Ensure these valves are reopened prior to flight.
12.10.3.24. Failed Speed Sensitive Switch. NOTE: The engine will not airstart once it
is shutdown inflight.
12.10.3.24.1. Pull Ignition Control Circuit Breaker on Copilot‘s Lower circuit
breaker Panel. NOTE: Any time the ignition control circuit breaker is pulled on an
inboard engine, the ice detection system is inoperative.
12.10.3.24.2. Open lower left side engine cowling on the affected engine.
12.10.3.24.3. Remove the speed sensitive control cannon plug (see Figure 12.8).
12.10.3.24.4. Install the pre-wired cannon plug from the HERK and secure it in place
(see Figure 12.8 and Figure 12.10). CAUTION: Pre-wired cannon plugs used as
jumpers must be wired as shown in Figure 12.10.
12.10.3.24.5. Secure all engine cowlings.
