C. Airworthiness Limitations
(1) Certain components, as well as the entire propeller,
may have specific life limits established as part of the
certification by the FAA. Such limits call for mandatory
replacement of specified parts after a defined number of
hours and/or cycles of use.
(2) Life limited component times may exist for the
propeller models covered in this manual. Refer to
the

Operators are urged to keep informed of airworthiness
information via Hartzell Service Bulletins and Service
Letters, which are available from Hartzell distributors
or from the Hartzell factory by subscription. Selected
information is also available on Hartzell Propeller’s
website at www.hartzellprop.com.
D. Overhaul Periods
In flight, the propeller is constantly subjected to vibration
from the engine and the airstream, as well as high centrifugal
forces. The propeller is also subject to corrosion, wear, and
general deterioration due to aging. Under these conditions,
metal fatigue or mechanical failures can occur. To protect
your safety and your investment, and to maximize the safe
operating lifetime of your propeller, it is essential that a
propeller be properly maintained and overhauled according
to the appropriate overhaul manual.
