Steve P.,
If the manufacturer's instructions require adherence to SB's and the like, and the FAR's require adherence to the manufacturer's instructions, doesn't that make SB's and the like mandatory in a roundabout way? (referring to certified aircraft)
Not to suggest anything unsafe by any means, but an experimental aircraft would not technically be affected by the SB's in question. Of course, explaining that to a wife might prove to be the bigger burden.
Regarding the brush/coil inspection, SB 3-08, here's something from the boss on July 10th
