Dear Sport Cub Owners,
Yesterday we mailed out a paper copy of Service Bulletin 23, which can be found on the Owner Support page on the website here. This document concerns the inline fuse holders and is applicable to all Sport Cub aircraft (S/N 0001 -00186).
There have been issues with fuse blocks overheating, which will be alleviated with the installation of new inline fuse holders. The instructions vary slightly depending on the currently installed fuses on your aircraft. Aircraft with the latest fuse holders already installed will require only minimal inspection in order to comply with the Service Bulletin.
Please contact customer support for any questions or parts. Thank you.
