Warning
People who operate a hovercraft 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 hovercraft. A mechanical failure could cause a failure in operation or create
vibrations sufficiently severe to damage the hovercraft.
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 classified as being safe to operate, 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 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 hovercraft. It is also among the most
critical to operation 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.
