TM 55-1510-218-MTF

10. Repeat for opposite engine.

*F. Engine Acceptance at Maximum Continuous Pow-

er (C-12F).

1. Record the following

*a. Engine serial number.

*b. Engine hours since new.

*c. Engine hours since overhaul.

2. Altitude -Establish level flight at 16,000 feet

pressure altitude.

3. Propeller levers - Set 2000 RPM.

4. Adjust the opposite engine to maintain 160

KIAS.

5. Set engine torque as specified by the engine ac-

ceptance graph (figure 15) on the engine to be

tested.

NOTE

Aircraft performance is based on obtaining

at least chart torque. Any engine must be

able to meet the chart torque value without

exceeding the TGT of 780C.

6. Allow conditions to stabilize for one minute

then record the following for each engine being

tested:

*a. Airspeed

*b. Pressure altitude

*c. Free air temperature

*d. TGT

*f. Torque

* g . N1
