I recently noted two ¼ inch hairline cracks on my Sensenich wood propeller Model W62HJ46G. The cracks are on opposite blades. One crack runs perpendicular to the trailing edge and the other runs perpendicular to the leading edge. Neither crack is radiating from a nick in the bIade. The prop has 87 hours on it. I spoke with Charlie at Sensenich and plan to send the prop in for inspection.
I noted that Sensenich offers several ground adjustable props for the Jabiru 2200 & 3300 engines. Their website states that vibration testing has only been conducted on the 80 hp engine. They also have ground adjustable models available for the 85-120 hp engines. If vibration testing has been completed on those models, I may be interested in upgrading the prop.

Wrt to Op Limitations, would an upgrade to a ground adjustable prop from fixed pitch constitute a major modification???
The ground adjustable is heavier. The Jabiru cowl is longer than the Rotax cowl. I will also have to consider the impact on Wt & Balance before making a final decision.
