Blade track is the ability of one blade tip to follow the other while rotating in almost the same plane.
Excessive difference in blade track - more than .0625 inch - may be an indication of bent blades or
improper propeller installation. Check blade track as follows:
A. With the engine shut down and blades vertical, secure to the aircraft a smooth board just under the
tip of the lower blade. Move the tip fore and aft through its full “blade-shake” travel, making small
marks with a pencil at each position. Then center the tip between these marks and scribe a line on
the board for the full width of the tip.
B. Carefully rotate propeller by hand to bring the opposite (or next) blade down. Center the tip and
scribe a pencil line as before and check that lines are not separated more than .0625 inch.
C. Propellers having excess blade track should be removed and inspected for bent blades, or for parts
of sheared “O” ring, or foreign particles, which have lodged between hub and crankshaft mounting
faces. Bent blades will require repair and overhaul of assembly.
