- abort if not corrected
-
Fuel Flow / EGT sensor failure during start
- Indications:
- 0 EGT or 0 FF
- EGT or FF Fail with corresponding EED Fail
- Actions:
- With fail indication, try Master/Slave and cycle EED power
- With no FF, move throttle past idle
- With no EGT, press start button harder
-
Excessive Fuel Flow during start
- Indications:
- FF exceeds 360 pph before ignition
- Actions:
- Abort start
- Motor for 2 minutes
- Reattempt start
- Abort aircraft for excessive fuel flow on second start
-
No EGT rise on start
- Indications:
- No EGT rise after 12 seconds of fuel flow
- Actions:
- Abort start
- Motor for 2 minutes
- Cycle EED Master/Slave and EGT power
- Reattempt start
- Considerations:
- If no EGT rise but RPM is rising, abort start
-
Excessive EGT on start
- Indications:
- EGT above 845C
- Actions:
- Abort start
- Motor for 2 minutes
- Attempt restart
- Considerations:
- Expect rapid EGT rise on second start attempt
- If EGT exceeds 925C, write up with max temp, duration, and other EED indications
-
Engine fire during start/taxi/runup
- Indications:
- FIRE warning lights, FIRE warning on MFD/HUD
- FEVER indications
- Ground crew signal (figure 8 with one hand, pointing at fire with other)
- Actions:
- Throttles OFF
- Emergency Ground Egress
- Considerations:
- Consider radio call to alert ground/fire chief
- Call for egress before switching battery/APU off
-
Emergency ground egress
- Indications:
- Need to egress in a hurry
- Willing to accept additional risk of emergency egress
- Actions:
- Notify ground/tower as appropriate
- EGRESS, EGRESS, EGRESS
- Throttles OFF
- Seat SAFE and pinned (confirm with RCP)
- Battery OFF
- Unstrap (2,1,2,2,2)
- Open canopy (normal, jettison, canopy breaker)
- Exit cockpit
-
Low Hydraulic Pressure (ground)
- Indications:
- Hyd Px below 1,500 psi when flight controls actuated
- MASTER CAUTION
- Actions:
- Cycle flight controls and recheck indicator
- If normal indications arent restored, abort the aircraft
- Considerations:
- Possible fluid leak
- Longer actuation times for FANGS equipt if low px in utility hyd system
-
Excessive hydraulic pressure on the ground (CAUTION light OFF)
- Indications:
- Hydraulic pressure above 3,200 psi after engine start
- Actions:
- Cycle flight controls and recheck indicator
- If normal indications arent restored, shut down engine and abort aircraft
-
Impending FOD Incident (ground)
- Indications:
- Foreign objects seen during ground ops
- Actions:
- Wait for objects to clear and call ground control to report
- Shut down engines to prevent damage
-
Deflated nose strut (ground)
- Indications:
- Nose strut clunks during taxi/runup
- Actions:
- Stop
- call for a tow back to the chocks
- shut down and egress normally
-
Smoke, fumes or odors in cockpit (ground)
- Indications:
- Smoke, fumes, or unusual odors in cockpit
- Actions:
- Gangload during analysis
- FEVER check treat as fire as appropriate
- Dont take off with continued indications
- Considerations:
- Could be caused by A/C system with dirty coalescer bag
- Combined with vibrations, could indicate A/C turbine failure select RAM DUMP
-
Generator failure with/without crossover (ground)
- Indications:
- Gen fail with crossover MASTER CAUTION and LEFT/RIGHT GEN light
- Right gen no cross RIGHT GEN, RIGHT FUEL PX, ENGINE ANTI ICE
- Left gen no cross LEFT GEN, LEFT FUEL PX
- Actions:
- Check RPM above generator cut in range
- Adjust affected engine RPM to other side of 65-75%
- If failure to shift suspected, turn generator off, taxi clear and shut down affected engine
- Assuming good crossover, attempt reset if successful, press
-
Improper flight control feel (ground)
- Indications:
- Binding or unusual feel during flight control check
- Actions:
- Abort and write up
-
Brake failure/locked brake
- Indications:
- Brakes dragging, locked, or inop
- Action:
- Attempt to clear taxiway
- Call for tow, shut down and egress
-
Loss of nosewheel steering
- Indications:
- Nosewheel steering inop while taxiing
- Actions:
- Use differential braking
- Attempt to clear runway/taxiway
- Call for tow, shut down, and egress
- Considerations:
- If at the end of a mission, try braking hard enough to compress the nosewheel strut
- If combined with low or fluctuating utility hydraulic pressure, suspect a leak
-
Nosewheel steering will not disengage
- Indications:
- Nosewheel steering wont disengage while taking the runway
- Actions:
- Abort the aircraft
-
Rudder pedal rod end failure
- Indications:
- While holding brakes during runup, rudder pedal fails
- Actions:
- Abort the takeoff
- Prepare to shut down and depart prepared surface
- Call for a tow, shut down, and egress
-
Nosewheel vibration
- Indications:
- Nosewheel vibration while taxiing
- Actions:
- Abort the aircraft
-
Departing a prepared surface
- Indications:
- Leaving taxiway/runway/ramp
- Actions:
- Shut down before departing
- Emergency ground egress
- Considerations:
- Primary dangers are engine FOD and landing gear damage
