RPM). Do not exceed temperature and torque
PROP GOVERNOR test switch - Release. Verify
that propeller RPM increases.
Left engine POWER lever - IDLE.
Repeat steps b through e for right engine.
* 12. Primary governors - Check as follows:
POWER levers - Set 1500 RPM.
PROP levers - Move aft to detent.
Propeller RPM - Check 1150 +50.
PROP levers - HIGH RPM.
* 13. Propeller low pitch stop - Check one engine at a
time as follows:
Aircraft - Position crosswind.
Read the corrected propeller torque in % at 1500
RPM from figure 1.
PROP lever - HIGH RPM (full forward).
POWER lever - Set 1500 RPM.
Torquemeter - Read and record torque.
POWER lever - IDLE.
Torque reading taken in step e must equal the
corrected torque in step b, within +2%.
