Q

EMERGENCY ENGINE SHUTDOWN

A

Engine shutdown without delay. Before Shutdown, check RRPM/NR, PTIT, ENG OIL PRESSURE AND ENG FAIL CAUTION to avoid shutting a good engine down. If temps start to rise fast (100 c/sec), move to stop and use fire pull handle

ENG COND lever— STOP
If you have a fire as well:
FIRE PULL handle — Pull
AGENT DISCH switch - as req
THEN:
Perform single engine failure procedures

POSITIVE IDENTIFICATION OF MALFUNCTIONING ENGINE IS A MUST.
FIRE PULL HANDLE AND MANUALLY CLOSING GATE VALVE AT REAR OF AIRCRAFT IS SECOND OPTION IF ECU FAULT MAKES SHUTDOWN BY ECL IMPOSSIBLE

If restart is attempted, wait 15 seconds after N1 reaches zero (allows fuel to drain)

Q

ABORT START

A

ENG COND lever — STOP
ENG START switch — Motor (if high PTIT is indicated). (Must be motored to decrease below 260c if above 350)
* Abort start: Engine shutdown to prevent PTIT from exceeding limits or when abnormal Ops are indicated

Q

Smoke and fume elimination

A

This procedure is used to prevent smoke and fumes (from rear) from entering the cockpit.
Be careful with opening ramp from cockpit. Could cause injury to FE.

A/S—above 60 Kias
Pilot’s sliding window—open
Helicopter attitude — Yaw left (one half to one ball width)
Upper half of main cabin door—open
RAMP EMER switch— as required

(If source of fire cannot be determined, close cargo ramp, but keep pilot’s window and upper half of main cabin door open to keep cockpit free of smoke).

  3. APU GEN…on
    Warning: with both gens failed, main tank boost pumps are inop. Descend below 6,000 PA. Reduce airspeed under 100 KIAS. LCT’s and DASH remained programmed at speed gens failed.
59
Q

RECT 1 or RECT 2

A

No bus tie:
1. Land as soon as possible
Note: no tie on #2 means no opening cargo hooks normally and no #2 hyd cooler fan.

60
Q

RECT 1 and RECT 2

A
  1. Land as soon as possible

Warning: If both transformer rectifiers have failed, the main tank boost pumps will be inoperative, a descent below 6,000 feet PA must be initiated as soon as possible to avoid a dual engine flameout. airspeed should be reduced to 100 KIAS or Vne, whichever is slower. LCT and DASH actuators will remain programmed at the airspeed at which the transformer rectifiers failed.

61
Q

What to remember if you abort a start?

A

If a second engine start is to be attempted, wait at least 15 seconds after the N1 (NG) tachometer indicates zero before attempting start. This will allow sufficient time for fuel to drain from the combustion chamber.
