Well, keep in mind that the Mooney M20 series and Beech 23/24 series use
these same donuts, and are generally retained by a metal plate, a collar
and an AN-5 bolt. I'm not aware of any problems with those installations.
If anything, I suspect that Van's may not have specified a large enough
pre-load force.
