Hartzell Propeller has
added to its series of how-to videos for pilots and mechanics. The
newest video covers the evaluation of structural composite propeller
blades by describing the ins and outs of composite prop pre-flight
checks for pilots.
"Pre-flight checks for structural
composite propellers are very similar to metal props with some
subtle differences," said Hartzell Propeller Executive Vice
President JJ Frigge.
"Hartzell's composite expert
Kevin Ryan walks pilots
through the pre-flight step by step, including a discussion of
nicks, gouges and paint erosion caused by runway debris."
In the video, Ryan
also addresses trailing edge impact damage from tow bars or other
ground handling equipment. He describes airworthy damage limits and
how to properly "coin tap" the blade to detect evidence of possible
delamination.
Hartzell uses
aerospace grade composite construction materials that are incredibly
durable, but they are not entirely immune to damage. Unlike aluminum
or wooden blades, Hartzell's composite propeller blades can be
restored to their original dimensions over and over again, providing
excellent life-cycle costs.
