Warning
People who fly 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 could cause a
forced landing or create vibrations sufficiently severe to damage
the aircraft.
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 certified 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 be properly maintained
according to the recommended service procedures and a
close watch be exercised to detect impending problems
before they become serious. Any grease leakage (see
chapters 5, 6, and 7) or oil leakage, unusual vibration, or
unusual operation should be investigated and repaired as it
could be a warning that something serious is wrong.

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 flight 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 MT-Propeller. Properly maintained it will
give you many years of reliable service.
