3.6 - Engine Emergencies

Question 1

PROPELLER - LOW PITCH

Indication: CAS warning - “Propeller Low Pitch”

Answer 1

Propeller pitch is less than 6 degrees (minimum pitch in flight) and the aircraft is not on the ground

1. PCL - Ensure forward of idle detent

if it is not possible to maintain speed and height

2. CONDITION LEVER - CUT-OFF/FEATHER
3. Aircraft - Emergency Descente and Landing Procedures

Question 2

ENGINE NP

Indication: CAS warning or caution - “ENGINE NP”

Answer 2

ON GROUND

1. NP - check NP RPM indication

if propeller RPM is below 930

2. PCL - Retard aft of idle detent or increse power until NP is above 950 rpm

if proppeller RPM is above 1760

3. PCL - Reduce power

IN FLIGHT

1. NP - Check NP RPM indication

if propeller RPM is below 1640

2. PCL - increase power
3. Aircraft speed - increase

If proppeller RPM is above 1760

4. PCL - Reduce power
5. Aircraft Speed - Reduce

If NP remains between 1760 and 1870 RPM

6. Aircraft - Continue flight, at low speed, using minimum possible power.

If NP is above 1870 RPM

7. PCL - Reduce power (idle if necessary)
8. Aircraft speed - Reduce to 120 kias or below
9. Land as soon as possbile, using minimum power, Retaining glide capability, to in case total propeller failure.

Question 3

ENGINE NG

Indication: CAS warning or caution - ENGINE NG

Answer 3

1. NG - Check NG % indication

if NG is above 103.5%

2. PCL - Reduce Power

If NG is above 104%

3. PCL - Reduce power
4. Aircraft speed - Reduce to 120 KIAS or below
5. Land as soon as possible, using minimum power, retaining glide capability.

if NG is below 60%

1. PCL - Increase power
2. Aircraft speed - increase

if engine does not respond to PCL inputs

Carry out engine failure in flight - partial loss procedure

Question 4

ENGINE TORQUE

Indication: CAS warning or caution - ENGINE TORQUE

Answer 4

1. TORQUE - Check indication

if torque above 44.3 psi

2. PCL - Reduce Power

if torque CAS warning or caution remains

land as soon as possible, retaining glide capabilty

Question 5

ENGINE ITT

Indication: warning or caution - ENGINE ITT

Answer 5

1. Check ITT indications

if is above 850

2. Reduce power

if caution or warning remains

Land as soon as possible retaining glide capability.

Question 6

ENGINE OIL PRESSURE

Indication: Warning or caution - Engine Oil Press

Answer 6

1. Check OIL P PSI

if oil pressure warning/caution is confirmed

2. NG - Check above 72%
3. Torque - Reduce to below 24 PSI

if oil pressure warning/caution reamains

4. Landing as soon as possible, using minimum power, retaining glide capability.

Question 7

ENGINE OIL TEMPERATURE

Indication: warning/caution - ENGINE OIL TEMP

Answer 7

ON GROUND

1. check OIL T Cº indication

if oil temp is high

2. Aircraft - Position into wind
3. CONDITION LEVER - Flight Idle
4. PCL - Increase power

if oil tem does not return to normal

5. ELECTRICAL HEAT/COOL Switch - Inhibit

IN FLIGHT

1. Check OIL T C º Indication

if oil temp is high

2. PCL - Reduce power

if oil temp does not returno to normal

3. Landing Gear - Extend

if Engine oil temp warning/caution remains

4. Land as soon as practical
5. maintenance required

Question 8

ENGINE STARTER ENGAGED

Indication: Warning - Starter Engaged

ON GROUND

Answer 8

1. CONDITION LEVER - CUT-OFF/FEATHER
2. START INTERRUPT - Push
3. BAT 1 and 2 - OFF
4. EXT PWR - OFF
5. Maintenance action required

Question 9

ENGINE OIL CHIP

Indication: CAUTION - Oil chip

Answer 9

1. Check and monitor engine parameter
2. PCL - Reduce to minimum required for safe flight
3. Land as soon as pratical

after landing maintenace required
