B. Static RPM Check - for Reciprocating Applications ONLY
NOTE: This operational check should be performed after
installation, maintenance, or propeller adjustment.
CAUTION:
A CALIBRATED TACHOMETER MUST
BE USED TO MAKE SURE OF THE
ACCURACY OF THE RPM CHECK.
(1) Set the brakes and chock the aircraft or tie aircraft down.
(2) Back the Maximum RPM Stop on the governor out
one turn.
(3) Start the engine.
(4) Advance the propeller control lever to MAX (max RPM),
then retard the control lever one inch (25.4 mm).
(5) SLOWLY advance the throttle to the maximum manifold
pressure.
(6) Slowly advance the propeller control lever until the engine
speed stabilizes.
(a) If engine speed stabilizes at the maximum power
static RPM specified by the TC or STC holder, then
the low pitch stop is set correctly.
(b) If engine speed stabilizes above or below the rated
RPM, the low pitch stop may require adjustment.
Refer to the Maintenance Practices chapter of this
manual.
(7) Stop the engine.
(8) Return the Maximum RPM Stop on the governor to the
original position.
(9) Test fly the aircraft to confirm the maximum rated RPM
specified in the aircraft TC or STC is achieved.
(a) Adjust the governor to the rated RPM with the
Maximum RPM Stop screw.
1 If the governor is adjusted to the rated RPM
with the maximum RPM stop screw, hold the
maximum RPM stop screw in place and torque
the maximum RPM stop locking nut in accordance
with Table 3-2, Torque Table.
