TH-57B/C EPs Flashcards
Land Immeadiately
Execute landing without delay
Land as Soon as Possible
Land at the first site at which a safe landing can be made
Land as Soon as Practicable
Extended flight is not recommended and the landing site and duration of flight are at the discretion of the Pilot in Command.
Abort Start Indications/Reasons
- Battery voltage stabilized below 17V
- Igniter failure
- Hung start
- Hot start
- Engine oil pressure remains at 0psi
- Rotors are not turning by 25% Ng
- Transmission oil pressure not indicated by 30% Nr
What is an igniter failure?
When TOT fails to rise after the twist grip is rotated to flight idle and Ng fails to rise above 20%
What is a hung start?
When TOT rises more slowly than normal and Ng rises slowly and stabilizes
What is a hot start?
When TOT exceeds limits and TOT caution light flashes twice per sec
Abort Start
- Twist grip — Close
If light off occurred:
2. Starter — OFF after TOT stabilizes at 400°C or below
If light off did not occur:
3. Motor engine for a minimum of 10 secs
Emergency Shutdown
- Twist grip — Close
- Fuel valve — OFF
- BAT switch — OFF
- STBY ATT IND switch — OFF (C)
- Rotor brake — Engage immediately (C)
- Helicopter — Egress, as required. Use the fire bottle or get clear of the aircraft
Post Shutdown Fire (Internal)
- Starter — Engage
- Fuel valve — OFF
- Igniter circuit breaker — Pull
- Starter — Secure after fire is extinguished
Engine or Transmission Oil Pressures
Instrument Failure
If engine oil pressure is exhibiting abnormal indications:
1. Land as soon as possible
If transmission oil pressure is exhibiting abnormal indications:
2. Transmission Malfunction Procedure — Perform
Engine or Transmission Oil Temperatures Malfunction
Instrument Failure
If engine oil temperature gauge exceeds red line limitations:
1. Land as soon as possible
If transmission oil temperature gauge exceeds red line limitations:
2. Transmission Malfunction Procedure — Perform
If either oil temperature gauge fluctuates or falls to zero:
3. Land as soon as practicable
Transmission Malfunction
If failure is imminent:
1. Land immediately
2. Shoulder harness — Lock
If failure is not imminent:
3. Land as soon as possible
Smoke and Fume Elimination
- ECS and DEFOG blower — OFF
- Vents/windows — Open
If smoke/fumes persist:
3. Slip or skid aircraft to eliminate smoke and fumes
If source of the smoke and/or fumes cannot be identified:
4. Land as soon as possible
Overtorque
If overtorque exceeding 120%:
1. Land as soon as possible
If overtorque of 120% or less:
2. Land as soon a practicable
Overtemp
- Land as soon as possible
Overspeed
- Land as soon as possible
Torquemeter Wet Line Rupture
Instrument Failure
- Monitor engine oil instruments
- Land as soon as possible
Suspected Fuel Leakage
- Land as soon as possible
If time and altitude permit:
2. Transmit position and intentions
3. Unnecessary electrical equipment — Secure
When on deck:
4. Emergency Shutdown — Complete
Hydraulic Power Cylinder Malfunction
- HYDRAULIC BOOST switch — OFF
- Helicopter — Regain control
- Airspeed — Adjust (to obtain most comfortable control movement level)
- Land as soon as possible
Engine Chip
- Check for secondary indications
If secondary indications exist:
2. Land as soon as possible
If no secondary indications exist, proceed as follows:
FIRST CHIP LIGHT:
3. Press CLEAR CHIP
If ENG CHIP remains:
4. Land as soon as possible.
If ENG CHIP extinguishes:
5. Note time and continue flight
SECOND CHIP LIGHT:
If within 30 minutes of the first:
6. Land as soon as possible
If more than 30 minutes have elapsed since the first light:
7. Proceed as with the first light.
Any subsequent ENG CHIP caution light within 50 hours of the first:
8. Land as soon as possible
Transmission Chip
First TRANS CHIP caution light:
1. Check for secondary indications
If secondary indications exist:
2. Transmission Malfunction Procedure - Perform
If no secondary indications exist:
3. Press CLEAR CHIP
If TRANS CHIP caution light remains illuminated:
4. Transmission Malfunction Procedure — Perform
If TRANS CHIP light extinguishes:
5. Note the time and continue flight
Second TRANS CHIP caution light:
If within 30 minutes of the first:
6. Transmission Malfunction Procedure — Perform
If more than 30 minutes have elapsed since the first TRANS CHIP caution light:
7. Proceed as with the first TRANS CHIP caution light
Any subsequent TRANS CHIP caution light within 50 hours of the first:
8. Transmission Malfunction Procedure — Perform
Tail Rotor Chip Caution
- Land as soon as possible
