Collective, airspeed REDUCE HEATER switch REPOSITION If condition persists: Throttle (affected engine) IDLE BEEP MAX Land as soon as practical If condition persists: Single engine shutdown in flight, Tab 3 |
|
|
N2 Turbine Seizure or Failure Engine power turbine or drive to C-BOX has seized or failed. Low N2 and QE. High N1 and ITT |
Collective, airspeed AS REQUIRED Throttle (affected engine) IDLE BEEP MAX Single engine shutdown in flight, Tab 3 |
|
|
High or Low Side Governor Failure On Ground HIGH SIDE: Fuel control failure causing engine runaway on affected engine. Symptoms include high Nr, N2, N1 and ITT LOW SIDE: Fuel control failure causing affected engine to produce less than required torque. Symptoms include low Q and low Nr |
Both throttles CLOSE Shutdown COMPLETE |
|
|
High or Low Side Governor Failure In Flight HIGH SIDE: Fuel control failure causing engine runaway on affected engine. Symptoms include high Nr, N2, N1 and ITT LOW SIDE: Fuel control failure causing affected engine to produce less than required torque. Symptoms include low Q and low Nr |
Collective ADJUST TO MAINTAIN ROTOR RPM Affected engine IDENTIFY Throttle (affected engine) IDLE If throttle reduction has no effect or manual fuel control is desired, proceed as follows: GOV switch (affected engine) MANUAL Throttle (affected engine) OPEN SLOWLY AS REQUIRED
|
|
|
Electrical Fire VMC, below 5000ft |
BATTERY BUS switches (1 and 2) OFF GEN switches (1 and 2) OFF Land as soon as possible |
|
|
Electrical Fire (Continued flight is necessary IMC or VMC and below 5000ft |
Emergency load switch EMERG LOAD GEN switches (1 and 2) OFF BATTERY BUS switches (1 and 2) ON Timer Start Note: Approximately 67 min of battery power is available with the emergency load switch in EMERG LOAD |
|
|
Battery Temp - Red Battery temperature has reached 71C (160F). Treat as thermal runaway |
BATTERY BUS switches OFF Visors DOWN Land as soon as possible Egress AWAY FROM NOSE |
|
|
Dual Generator Failure |
CAUTION Do not select EMERG LOAD at pressure altitudes above 5000 feet (1524m). Both fuel boost pumps will become inoperative, resulting in possible fuel starvation |
|
|
Main Driveshaft Failure Driveshaft powering the transmission has failed |
Autorotate AIRSPEED AS REQUIRED Throttles CLOSE Fuel switches OFF Crew, pax BRIEF |
|
|
Loss of Tail Rotor Thrust - In Hover Loss of yaw control due to failure of tail rotor power train, control linkages or tail rotor components |
Throttles IDLE Collective RAISE TO CUSHION LANDING |
|
|
Loss of Tail Rotor Thrust - In Flight Loss of yaw control due to failure of tail rotor power train, control linkages or tail rotor components |
Collective REDUCE TO MINIMUM If yaw is uncontrollable: Throttles IDLE Autorotate 70 KIAS MINIMUM Carry out autorotative landing |
|
|
Loss of Tail Rotor Control - In Hover Tail rotor pitch is frozen at a particular pitch setting due to a stuck pedal or other linkage failure |
Collective LOWER GENTLY AND LAND |
|
|
Loss of Tail Rotor Control - In Flight Tail rotor pitch is frozen at a particular pitch setting due to a stuck pedal or other linkage failure |
Collective, airspeed ADJUST AS REQUIRED Check for FOD BOTH SIDES Pedal position CHECK Throttle frictions AS REQUIRED Controllability CHECK Approach SHALLOW TO NORMAL |
|
|
Sprag Clutch Non-Engagement No engagement of combining gearbox sprag clutch assembly to positive drive from engine following engine start. Indicated during first engine start by zero Nr and during second start by 10% to 15% higher N2 than engaged engine and near zero torque |
Both throttles CLOSE Shutdown COMPLETE NOTE: Monitor engine instruments following shutdown of non-engaged engine. Indications of a sudden (hard) engagement are abrupt N2 deceleration, jolt or noise |
|
|
XMSN Oil Pressure Pressure less than 30 psi |
Power REDUCE XMSN oil pressure, temperature CHECK If outside limits Land as soon as possible If within limits Land as soon as practical NOTE: For any transmission problems, minimize power changes |
|
|
XMSN Oil Temperature Temperature above 110C |
Power REDUCE XMSN oil temperature, pressure CHECK If outside limits Land as soon as possible If within limits Land as soon as practical NOTE: For any transmission problems, minimize power changes |
|
|
C-BOX Oil Pressure Pressure less than 40 psi |
Power REDUCE C Box oil pressure, temperature CHECK If outside limits Land as soon as possible If within limits Land as soon as practical NOTE: The 21-psi value at which the warning light illuminates is well below the system operation minimum of 40 psi. Therefore the pilot should not rely on the C-BOX OIL PRESS warning light as the primary indication of low C-BOX oil pressure but on the C-BOX gauge |
|
