Hi all....On a typical aircraft prop installtion, the heads of the prop
bolts are drilled and then safety wired. This works, because the prop flange
has fixed threaded sleeves into which the prop bolts fasten.  On my Ross
PSRU, there are thru-bolts, and instead of the bolts being threaded into a
fixed unit, they go through the crush plate on the engine side of the prop
and have locknuts instead.  What might be the best method of securing these
type of prop bolts?  Unfortunately, I have seen a few other rotary
installations with a Ross redrive, but never bothered to look to see if the
prop bolts had safety wire, etc.  Thanks for any and all suggestions. Paul
