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.
