CHAPTER 12: GROUND EMERGENCIES Flashcards
Utilization of the Engine Fire on the Ground checklist may not be effective against a ________ and consideration should be given to executing the Engine Tailpipe Fire checklist
tailpipe fire
Note regarding torching and engine fire
Do not confuse torching with an engine fire. Torching is usually brief and extinguished by following the aborted engine start procedure
If the Flight Crew is alerted of an engine fire by ground personnel or Mission Crew without activation of the engine fire warning system, a
tailpipe fire may exist.
Condition: One or more of these occur:
- Engine fire warning.
- Ground personnel or Mission Crew notify Flight Crew of engine fire.

Condition: One or more of these occur:
- Engine fire warning.
- Ground personnel or Mission Crew notify Flight Crew of engine fire.
Memory items
- Engine start lever/FUELCONTROL switch (affected engine) — CUTOFF. (PM)
- Engine fire switch (affected engine) — Pull and rotate to the stop until bottle discharge. (PM)
- Engine fire switch (affected engine) — Rotate to the other stop until bottle discharge. (PM)
►►Proceed to the Ground Evacuation checklist, paragraph 12.7.1.
What typically causes engine tailpipe fires?
Engine tailpipe fires are typically caused by engine control malfunctions that result in the ignition of pooled fuel and can be damaging to the engine.
Generally an engine tailpipe fire occurs on the ground with
no engine fire warning
How would you describe a tailpipe fire?
A tailpipe fire is typically reported as sustained visible flames emanating from the tailpipe.
What may be a reason that there is no engine fire warning associated with a tailpipe fire?
A tailpipe fire is typically external to the engine compartment monitored by the engine fire detection/protection system, thus limiting the effectiveness of engine fire extinguishing agents.
Engine fire extinguishing agents may not be effective against a tailpipe fire. Why?
A tailpipe fire is typically external to the engine compartment monitored by the engine fire detection/protection system, thus limiting the effectiveness of engine fire extinguishing agents.
Due to limited effectiveness of fire extinguishing agents on a tailpipe fire, __________ the engine is the primary means of extinguishing the fire
motoring
What are three considerations when dealing with a tailpipe fire?
- Due to limited effectiveness of fire extinguishing agents on a tailpipe fire, motoring the engine is the primary means of extinguishing the fire.
- To prevent an inappropriate evacuation, the flight crew should be notified without significant delay.
- Engine Fire Protection Systems are not effective against a fire inside the tailpipe.

If smoke, fire or fumes are encountered during preflight (possibly with reduced aircrew numbers), the senior qualified
crewman SHOULD/SHALL execute the Smoke, Fire, or Fumes Emergency checklist and assign the available aircrew duties to isolate the source.
Shall
If the source of the smoke, fire or fumes cannot be isolated,
SHALL secure power
SHALL evacuate
If the source of the smoke, fire or fumes cannot be isolated, power to the aircraft shall be secured in the flight deck and the aircrew shall evacuate.
Note regarding extending air stair from interior during smoke, fire, or fumes on ground
If the airstair must be extended from the interior to facilitate evacuation and ac power has been secured, the battery switch needs to remain ON and the standby function utilized to extend the ladder.
Warning regarding egress through the two sliding flight deck windows
Egress through the two sliding flight deck windows is difficult and should be used only in extreme emergency. Egress wearing emergency equipment may result in a fall causing serious injury or death.
