IS NOT AUTHORIZED. UNAPPROVED
INSTALLATION AND REMOVAL
TECHNIQUES MAY CAUSE DAMAGE TO
THE PROPELLER THAT MAY LEAD TO
FAILURE RESULTING IN AN AIRCRAFT
ACCIDENT.
WARNING 2
: WHEN INSTALLING THE PROPELLER,
FOLLOW THE AIRFRAME
MANUFACTURER’S MANUALS AND
PROCEDURES, AS THEY MAY CONTAIN
ISSUES VITAL TO AIRCRAFT SAFETY
THAT ARE NOT CONTAINED IN THIS
OWNER’S MANUAL.
(1) Make sure the propeller is removed before the engine is
removed or installed in the airframe.
(2) Follow the airframe manufacturer’s instructions for
installing the propeller. If such instructions are not in
the airframe manufacturer’s manual, then follow the
instructions in this manual; however, mechanics must
consider that this owner’s manual does not describe
important procedures that are beyond Hartzell’s control.
In addition to propeller installation procedures, items
such as rigging and preflight testing of flight idle blade
angle, installation and adjustment of de-ice equipment,
and propeller synchronization devices are normally
found in the airframe manufacturer’s manuals.
B. O-ring and Propeller Mounting Hardware Identification
Refer to Table 3-1 for specific part numbers of O-rings
and propeller mounting hardware, and propeller model
