A nice crack popped up on my spinner, so I planned my standard fix of backing the area with some carbon fiber thread to strengthen it and fill on the top. Upon removal of the spinner, I found that the area right next to the leading edge of both FP prop hubs have an approximately two inch wear strip from the front bulkhead, as if the bulkhead is slightly oval in shape, with no wear anywhere else around the circle of the spinner. Seems kind of coincidental to have it on both sides, any particular reason for this?
