(a) Consumable material reference numbers appear
with the prefix “CM” directly following the material
to which they apply. For example, an adhesive that
is reference number 16 will appear as: adhesive
CM16. Only the material(s) specified can be used.
7. Safe Handling of Paints and Chemicals
(Rev.1)
A. Instructions for Use
(1) Always use caution when handling or being exposed to
paints and/or chemicals during propeller overhaul and/or
maintenance procedures.
(2) Before using paint or chemicals, always read the
manufacturer’s label on the container(s) and follow
specified instructions and procedures for storage,
preparation, mixing, and/or application.
(3) Refer to the product’s Material Safety Data Sheet
(MSDS) for detailed information about the physical
properties, health, and physical hazards of any paint or
chemical.
8. Calendar Limits and Long Term Storage
(Rev. 1)
A. Calendar Limits
(1) The effects of exposure to the environment over a period
of time create a need for propeller overhaul regardless of
flight time.
(2) A calendar limit between overhauls is specified in
Hartzell Propeller Inc. Service Letter HC-SL-61-61Y and
in the propeller owner’s manual.
(3) Experience has shown that special care, such as
keeping an aircraft in a hangar, is not sufficient to permit
extension of the calendar limit.
(4) The start date for the calendar limit is when the propeller
is first installed on an engine.
(5) The calendar limit is not interrupted by subsequent
removal and/or storage.
(6) The start date for the calendar limit must not be
confused with the warranty start date, that is with certain
exceptions, the date of installation by the first retail
customer.
