Always worthwhile to ask questions. I
honestly never thought about mount style being related to the
tension bolt issue, since it's been an ongoing 'thing' with
rotaries. A different mounting style might have an effect, so it's
worth at least asking the question.

The fact that there are failures in cars may or may not have

The assumption that a particular piece of equipment has no
effect on any other piece of equipment in an aircraft can
possibly shut down an important thread of inquiry that may be a
safety issue.
Please don’t misunderstand and think that i have a pony in
this race, i am just curious as i am when ever things such as
this bolt break take place.
How many on this list have had a broken bolt—
Where on the bolt did it happen
Which bolt or bolts suffered the break
Which model and sub model was it in
Was the engine blown
What engine mount was used
Was it tractor or pusher
Propeller installed
Perhaps the data sample will be too small to derive any
conclusions. But the responses just might show something of
importance

Now I'm now confused. Are we talking about
mount bolt failures, or engine assembly bolt (those 15"+
long ones) failures? I thought that mount design was one
discussion, and block assy bolts was a different subject.
If you're asking whether mount style affects block assy
bolt failure, I'd think it's extremely unlikely. The bolts
have failed in cars, and in a/c using the bed mount plate.
