As a fellow pilot, I urge you to read this Manual thoroughly. It
contains a wealth of information about your new propeller.
The propeller is among the most reliable components of your
airplane. It is also among the most critical to ight safety. It therefore
deserves the care and maintenance called for in this Manual. Please
give it your attention, especially the section dealing with Inspections
and Checks.
Thank you for choosing a Hartzell propeller. Properly maintained it
will give you many years of reliable service.
Jim Brown
Chairman, Hartzell Propeller Inc.

People who y should recognize that various types of
risks are involved; and they should take all precautions to
minimize them, since they cannot be eliminated entirely.
The propeller is a vital component of the aircraft. A
mechanical failure of the propeller could cause a forced
landing or create vibrations su󰀩ciently severe to damage
the aircraft, possibly causing it to become uncontrollable.
Propellers are subject to constant vibration stresses from
the engine and airstream, which are added to high bending
and centrifugal stresses.
Before a propeller is certied as being safe to operate
on an airplane, an adequate margin of safety must be
demonstrated. Even though every precaution is taken in the
design and manufacture of a propeller, history has revealed
rare instances of failures, particularly of the fatigue type.
It is essential that the propeller is properly maintained
according to the recommended service procedures and
a close watch is exercised to detect impending problems
before they become serious. Any grease or oil leakage,
loss of air pressure, unusual vibration, or unusual operation
should be investigated and repaired, as it could be a
warning that something serious is wrong.

MESSAGE 61-00-15
For operators of uncertied or experimental aircraft
an even greater level of vigilance is required in the
maintenance and inspection of the propeller. Experimental
installations often use propeller-engine combinations that
have not been tested and approved. In these cases, the
stress on the propeller and, therefore, its safety margin is
unknown. Failure could be as severe as loss of propeller
or propeller blades and cause loss of propeller control
and/or loss of aircraft control.
Hartzell Propeller Inc. follows FAA regulations for propeller
certication on certicated aircraft. Experimental aircraft
may operate with unapproved engines or propellers or
engine modications to increase horsepower, such as
unapproved crankshaft damper congurations or high
compression pistons. These issues a󰀨ect the vibration
output of the engine and the stress levels on the propeller.
Signicant propeller life reduction and failure are real
possibilities.
Frequent inspections are strongly recommended if
operating with a non-certicated installation; however,
these inspections may not guarantee propeller reliability,
as a failing device may be hidden from the view of the
inspector. Propeller overhaul is strongly recommended to
accomplish periodic internal inspection.
Inspect the propeller/blades in accordance with the
applicable operation/maintenance documents.

AIRWORTHINESS LIMITATIONS
1. Replacement Time (Life Limits)
A. The FAA establishes specic life limits for certain component
parts, as well as the entire propeller. Such limits require
replacement of the identied parts after a specied number
of hours of use.
B. The following data summarizes all current information
concerning Hartzell life limited parts as related to propeller
models a󰀨ected by this manual. These parts are not life
limited on other installations; however, time accumulated
toward life limit accrues when rst operated on aircraft/
engine/propeller combinations listed, and continues
regardless of subsequent installations (which may or
may not be life limited).
