Dear Sport Cub Owners,
Sensenich Propellers has just released the following document on their website: Notification No. CN-1-13. This document, which can be found on our website here, is directed at aircraft owners and operators using Continental O-200 engines and Sensenich C72AE propellers (i.e. Sport Cub owners with the Sensenich ground adjustable propeller). The issue deals with magneto failures due to propeller harmonics.
CubCrafters has been closely involved in this issue with Sensenich, Continental, and the affected owners and aircraft. If you have any questions feel free to post them here or contact Customer Support.
