Inspection After First Run-Up
1. Inspect the propeller system blades and spinner for any nicks,
cracks, or chips.
2. Inspect each aluminum blade ferrule and blade intersection
(located at the root end of blade where the silicone sealant is
visible) for movement and/or signs of chafing. There should be
no movement between aluminum ferrule and blade. Notify Whirl
Wind Aviation immediately if movement is detected.
3. Gently shake each propeller blade to feel for blade movement in
the hub. Blade shake movement is allowed up to 1/8 inch,
measured from the tip. Radial play of up to 2 degrees is
acceptable. If the check shows values above these tolerances
contact Whirl Wind Aviation immediately. Movement is only
allowed between the aluminum blade ferrule and the propeller
hub, not as described in item #2 above.
4. Inspect the nickel leading edge erosion shield. The nickel
erosion shield should not be loose or have any cracks. Small
paint cracks parallel to and along the edge of the shield where
the nickel and paint meet are acceptable.
5. Check spinner dome and the aft and forward bulkheads for
cracks of any kind or looseness.
6. No grease or oil leaks should be detected. NOTE: A small
amount of grease leakage may occur in new propellers (first 2 to
5 hours) or in hot climates with high RPM conditions.
7. Before every flight the prop-control should be cycled at least
twice to circulate the engine oil. In cruise flight any number of
RPM settings are possible within the engine and propeller
limitations. The RPM restrictions from the engine and propeller
manufacturers must be strictly observed.
