    Default Spinner back plate

    At Annual today my IA notice that the prop-bolts had started to warp the spinner back plate and said I should start looking for a replacement. If anyone has one gathering dust I'd definitely be interested in it.
    Rest of the spinner is in good shape.

    Thanks,
    Grant

    Unfortunately this is TOO common on many Piper spinners.

    I have used washers with a larger Outside Diameter & it reduces the "dimpling" at the prop bolt holes.

    My thought is has no effect on balance & a Minor Alteration-log entry only.

    Piper used a special larger area washer. Here is a thread about it. I will have to put the pictures back in it since the move to the new software. http://www.shortwingpipers.org/forum...ght=prop+bolts
