For engines that exceed 730°C TGT, engine acceptance at
maximum cruise power, must be conducted.
ENGINE ACCEPTANCE AT MAXIMUM CRUISE POWER.
The engine acceptance at maximum cruise power check
needs to be performed only if the TGT observed during the
speed check at maximum cruise power exceeds 730°C.
Record the following:
*a. Engine serial number.
*b. Engine hours since new.
*c. Engine hours since overhaul.
Altitude - Establish level flight at 25,000 feet pressure altitude.
Propeller levers - Set 1900 RPM.
Adjust the opposite engine to maintain 175 KIAS.
Free air temperature - Record
Set engine torque as specified by the maximum cruise speed/engine acceptance chart (figure 6) for the
recorded indicated free air temperature, on the engine to be tested.
Allow conditions to stabilize for one minute then record the
*b. Pressure altitude
*c. Free air temperature
*d. Propeller RPM
