Land/Ditch Immediately Criteria
− Due to the seriousness of the malfunction, the aircraft shall be landed or ditched without delay. If extreme sea/terrain conditions seriously jeopardize aircrew survivability,the aircraft may be air taxied to the nearest suitable site and landed or ditched immediately.
Land as soon as POSSIBLE criteria:
− Aircraft shall be landed at the first site at which a safe landing can be made.
LAND AS SOON AS PRACTICABLE Criteria:
Extended flight is not recommended. The landing site and duration of flight is at the discretion of the pilot in command.
Abort Mission Criteria

WARNINGS and NOTES associated with Internal Cabin Fire
WARNING:
The severity of the fire and actual flight conditions (night/instrument) will dictate the immediate procedures to be followed. It may not be advisable to secure all electrical power, thus losing AFCS and flight instruments, prior to achieving VMC.
With the Emergency Electrical Cutoff switch in the OFF position, the flotation system will not be available. Consideration should be given to activating floats prior to securing if ditching is anticipated.
NOTE:
An avionics fire will be fought by disconnecting enough camlocks on the avionics rack panel to allow access for the fire extinguisher nozzle. Short blasts are advised to preserve extinguishing agent in case of a reflash. Close rack panel and monitor for re- flash.
All communication, both internal and external, and all aircraft system lighting will be lost after activating Emergency Electrical Cut−Off switch.
Placing the Emergency Electrical Cut- off switch to OFF removes power to the tail rotor hydraulic isolation valve, closing the valve. With the 10−bladed tail rotor hub installed, this action may result in considerable feedback in the pedals.
Smoke and Fume Elmination
- HEAT/COOL SWITCHES − OFF
- RAM AIR − OPEN
- CABIN SLIDING DOOR − OPEN
- PILOT WINDOWS − OPEN
- LAND AS SOON AS PRACTICABLE
Smoke and Fume Elimination: Warnings, Cautions and Notes
WARNING:
If fuel fumes are present, limit radio transmissions to a minimum. Due to antenna location, COMM 1 is the best choice.
CAUTION:
To avoid the possibility of rotor blade or structural damage, do not jettison any window or door unless deemed absolutely essential for smoke or fume removal.
NOTE:
The SEAS bottle, located in crew survival vests, may be a good source of clean air in the event of an unbreathable environment. Normally,no toxic quantities of carbon monoxide gas or other gases are present from the engine exhaust. Objectionable odors from the ECS are sometimes experienced due to internal oil leaks in the engines. These fumes may be noxious to the crew and should be entered in ALMIS. Opening the sliding door and the pilots’ windows in−flight will assist in removing objectionable fumes and odors.
Engine Fire Post Shutdown Symptoms:
- TOT rises rapidly or does not decrease within 10 seconds after the FADEC control switch has been placed in the OFF position
Engine Fire Post Shutdown
- FADEC CONTROL SWITCH − CHECK OFF
- BOOST PUMPS − CHECK OFF
If high TOT still evident after 10 seconds: - EMERGENCY FUEL SHUTOFF LEVER − SHUT OFF
- CRANK BUTTON − DEPRESS UNTIL TOT DECREASES
If TOT continues to rise or does not decrease: - EMERGENCY ELECTRICAL CUTOFF − OFF
- ROTOR BRAKE − ON
- EVACUATE AIRCRAFT
ABNORMAL VIBRATIONS
severe or intolerable vibrations of unknown origin
- LANDING/HOVER CHECKLIST − COMPLETE (200−foot checks at a minimum based on urgency)
- LAND/DITCH IMMEDIATELY
ABNORMAL VIBRATIONS(Moderate vibrations)
- CRUISEAIRSPEED−75−120 KIAS
- AVOID ABRUPT MANEUVERS
- LAND AS SOON AS POSSIBLE
Notes for Unusual Vibes
An unusual vibration should be investigated to determine its cause. The perceived severity of the vibration will determine whether continued flight is appropriate. As a guide, slight vibrations would not be apparent to experienced aircrew unless their total attention was directed to the vibrations. Moderate vibration would be noticeable to experienced aircrew but it does not affect their work or concentration. Severe vibration is immediately apparent to experienced aircrew and task performance can only be completed with difficulty. Intolerable- vibrations require aircrews sole preoccupation to reduce the vibration level.

MAJOR FADEC/GOVERNOR FAILURE Symptoms:
- FADEC No. 1 or 2 FAIL caution light illuminated
- Red ENGINE STATUS light on the overhead quadrant illuminated
- OEI GOV mode page displayed
- Affected engine will not respond to collective movement due to Fuel Flow metering being frozen at the rate present when the FADEC failed
MAJOR FADEC/GOVERNOR FAILURE
- COMPLETE THE “BIG 4”
- TRNG SWITCH − FLT
- FADEC BACKUP SWITCH (affected engine) − CONFIRM - BACKUP
MAJOR FADEC/GOVERNOR FAILURE: Note & Warning
NOTE:
FADEC logic is designed to cancel the Training Mode in
the event of an actual engine failure. However, if the failure is in the form of a Level 3 FADEC failure, EBCAU operation, if selected, will conflict with Training Mode logic and FADEC operation will be unpredictable.
In backup mode, FADEC will match the N1 of the affected engine to the N1 of the good engine. While N1 matching is assured, there will be some acceleration delay on the engine in backup mode.
WARNING:
With the FADEC Backup Switch in backup, N1 matching will occur without regard to the opposite engine’s current N1 setting.
The FADEC Backup Switch shall not be in the backup position when an engine is at training idle.
