Engine Fire AL5

Indication: Fire warning light on

Pilot’s action

1. Warn crew 2. Close HP cock 3. Close LP cock 4. Press fire extinguisher button 5. Shut engine air switch 6. Switch off booster pumps of appropriate engine 7. Order AEO to switch OFF appropriate alternator 8. Order AEO to inspect engine through periscope

AL5


10-2

XM655 AL5

Engine Fire - Continued AL5

AEO’s actions

1. Switch OFF appropriate alternator. Carry out alternator failure drill2. Inspect engine through periscope

NOTE 1: Should any other indications of fire be observed apart from the fire-warning light, e.g. excessive JPT smoke, flames, etc., the captain may also close down the adjacent engine on the same side, using drills laid down above, except for operating the fire extinguisher button and switching OFF the alternator.

NOTE 2: (a) If the fire warning light goes out and there are no other indications of fire, it can be assumed that the fire has been extinguished. No attempt should be made to relight the engine.

NOTE 2: (b) If the adjacent engine has been closed down, the captain may at his discretion, when the fire has been extinguished, relight the engine, or use its fuel to feed the other engines.

AL5

End of Emergency procedure – Fire – Engine Fire


10-3

XM655 AL5

AAPP Fire AL5

Indication: Fire warning light on in head of extinguisher button

AEO’s actions

1. Warn crew 2. Press extinguisher button 3. Master switch OFF

The warning light should go out when the fire is extinguished

NOTE: The LP cock is closed automatically when the fire extinguisher button is pressed and consequently, on run-down of the engine, the AAPP supply will come off the bus-bar. The AAPP starting circuit is electrically locked out and can only be broken by removing fuse No. 961 in 62P (vital bus-bar).

Brake Fires AL5

Captain’s actions

After clearing the runway, stop the aircraft and have the brakes inspected by a rear crew member.

AL5

Brakes smoking AL5

1. Warn the control and request that a fire tender be dispatched to the aircraft.2. Do not apply the parking brake; hold the aircraft with minimum amount of foot brake 3. Order the crew to take fire extinguishers and powder (if carried) to the brakes to assist the fire

tender party. 4. Carry out the after-landing checks; do not close down Nos.1 and 4 engines if still running. 5. When the brakes are cool, recall the crew and order the fire tender to follow the aircraft. 6. Start taxying. Close down Nos.1 and 4 engines when the aircraft is moving. 7. Use the minimum amount of breaking. 8. On reaching dispersal, do not apply the parking brake; hold the aircraft with the minimum amount

of foot brake until the chocks are in position. 9. Warn the crew chief to keep the fire tender in the vicinity of the aircraft until the brakes are cold. 10. Order the brakes to be checked in the F.700

XM655 AL5

Brake fires – Continued AL5

Brakes on fire AL5

Captain’s actions

1. Warn the control tower and request that the fire tender be dispatched to the aircraft. 2. Stop the aircraft. Do not apply the parking brake. Hold the aircraft with the minimum of foot

brake. 3. Order the crew members to take the fire extinguishers and powder to the brakes. 4. Do not close the HP cocks on Nos.1 and 4 engines, if still running in case of fuel dump into the

brakes. 5. When the file is under control, carry out the closing down checks and leave the aircraft to be

towed to dispersal.

Crew members

1. When the aircraft has stopped, collect fire extinguishers and powder (if carried) and go to the fire. 2. Approach the wheels from the fore-and-aft direction, i.e. in line with the tyres and not, repeat

not, in line with the axle. 3. Apply powder to the brakes and endeavour to bring the fire under control.


10-6

XM655 AL5

Brake fires – Continued AL5

Brakes on fire - Continued AL5

4. Keep the captain informed of the state of the fire5. Do not use water/glycol extinguishers on the burning brakes, unless in emergency and if no other

method of fighting the fire is available. 6. When the fire is out, return to the cabin and carry out the closing-down checks

NOTE 1: After brakes smoking or on fire the aircraft should not be flown until the brakes have been inspected.

NOTE 2: Aircraft are not, repeat not, to be taxied with a crew member on the door to watch the brakes.

XM655 AL5

Electrical Failures AL5

Alternator Failures - General AL5

(a) Indications. A protective systems malfunction or light failure may result in one or more indications not being immediately apparent.

(b) Bus-bar failures. If it is not possible to restore power to the failed bus-bar(s) before loads begin to run down (3-4 secs.) the loads must be switched OFF before attempting to restore the electrical supply.

NOTE 1: If an alternator has failed but not tripped off line, switch OFF all loads connected to its bus-bar before switching off the alternator.

NOTE 2: If the RAT has taken over the sync. Bar and failed do not press the extra supplies trip unless all four bus-bars are feeding their loads satisfactorily.

(c) Paralleling. Do not parallel alternators subsequent to unexplained failures. (d) AAPP starting. Post-Mod 1271, a cartridge start will be available only whilst the non-essential bus-

bar are tripped.
