Failure to comply may result in damage to engine.

Question 9

During engine start cycle, engine may shut down automatically for no light off, stagnate start, or flame out. Start switch must be placed to stop. After Ng decreases to zero percent,

Answer 9

engine shall be motored for 30 seconds to remove unburned fuel and gases from turbine section before attempting another start.

Question 10

Do not exceed starter duty cycle of 70 seconds on, 1 minute off, for a total of five cycles. After five cycles,

Answer 10

the starter must be allowed to cool for 20 minutes. Failure to comply may cause damage to engine and airplane.

Question 11

Do not start engine with an inoperative suction

Answer 11

boost pump since damage to engine driven hydraulic pump may result.

Question 12

If there is no positive indication of hydraulic pressure within 25 seconds after propeller rotation,

Answer 12

or if hydraulic pressure is not within normal limits when propeller speed stabilizes, immediately discontinue start.

Question 13

Engine oil pressure must indicate within 15 seconds after Ng rotation and

Answer 13

PGB oil pressure must indicate within 15 seconds after Np rotation.

Question 14

Monitor wind speed and direction (71-00-02) throughout

Answer 14

engine run operations or damage to engine and propeller could occur.

Question 15

Do not operate any engine above flight idle without

Answer 15

operating engine on opposite wing at the same power setting.

Question 16

Any time another airplane passes or stops in front of the test airplane,

Answer 16

the engine power lever must be reduced to GND IDLE.

Question 17

Failure to comply with any of the above men- tioned cautions may result in

Answer 17

damage to the engine and airplane.

Question 18

Propeller blade angle position can vary from

Answer 18

-17 degrees to feather prior to engine start.

Question 19

If the DEICING TIMER UNIT circuit breakers in the upper main AC panel are open, the ACAWS message PROP A/I PWR FAIL will appear after propeller reaches 500 RPM.

Answer 19

If the circuit breakers are closed, the ACAWS message will only occur in the event of an actual failure/fault within the propeller ice detection system.

Question 20

Monitor fuel panel throughout engine operations. Maintain a fuel quantity balance not to exceed 1,000 pounds difference between symmetrical main tanks (1 and 4; 2 and 3).

Answer 20

In addition, an overall balance of not more than 1,500 pounds difference must be maintained between wings.

Question 21

Engine runs for maintenance checks will be made in accordance with the

Answer 21

referencing maintenance manuals.

Question 22

Do not attempt to start the engine if a start failure message is displayed on ACAWS.

Answer 22

Failure to comply may result in a hot start.

Question 23

Limit engine power to ground idle when the oil temperature is less than 0 C. Limit power to 1,000 horsepower for oil temperature below

Answer 23

45 C. Failure to comply may result in damage to engine.

Question 24

Avoid stabilized operations between 52-68 percent and

Answer 24

75-85 percent Np RPM, which are critical speed ranges for propeller and turbine shaft. Failure to comply will result in damage to the engine, and may result in loss of power.

Question 25

When operating a single engine, except for Hotel mode, maintain horsepower above

Answer 25

50 HP to avoid augmenter valve chattering.

Question 26

If GEN 1, 2, 3, or 4 FAIL ACAWS message appears anytime during engine run,

Answer 26

perform emergency engine shutdown. Failure to comply may result in damage to the engine.

Question 27

Generator will drop off line with engine operating in

Answer 27

low speed ground idle.

Question 28

Each engine should be run a minimum of

Answer 28

2 minutes at low speed ground idle before engine shutdown.

Question 29

Do not motor engine when a tailpipe fire exists on engine shutdown.

Answer 29

Tailpipe fire may be caused by oil leak in turbine section and motoring engine will only intensify the condition.

Question 30

All propellers are required to be

Answer 30

feathered after engine shutdown.

Question 31

Engine hydraulic pump switches must remain on after final engine shutdown to

Answer 31

prevent damage to hydraulic shutoff valve.

Question 32

All four PROP AUX PUMP electronic circuit breakers should now be open to prevent

Answer 32

inadvertent feather pump operation and engine oil flooding.

Question 33

Minor grease leakage is normal after installation of a new or overhauled propeller.

Answer 33

Grease leakage is allowed for up to the first 40 hours of operation.

Question 34

Do not exceed starter duty cycle of 70 seconds on, 1 minute off, for five cycles. After five cycles,

Answer 34

starter must cool for 20 minutes. Failure to comply may cause damage to starter, engine, and airplane.

Question 35

When FADEC senses that ignition has not occurred,

Answer 35

a controlled engine shutdown will begin.

Question 36

Due to high wind loads aft of propeller during engine shutdown,

Answer 36

engine must not be shut down for any reason with mechanic on work stand or in immediate area aft of propeller. Once mechanic is clear, shut down engine as required.
