Hartzell has added to its series of how-to videos and the newest one covers the evaluation of structural composite propeller blades by describing the ins and outs of composite prop pre-flight checks for pilots.
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. Also covered is trailing edge impact damage from tow bars or other ground handling equipment.
Although Hartzell uses aerospace grade composite construction materials that are incredibly durable, they are not entirely immune to damage. The composite propeller blades can be restored to their original dimensions over and over again providing excellent life-cycle costs.
