I have been maintaining a spreadsheet as well, we can collaborate later. Print the sheet as a PDF and then post via picasa. Kind of a pain. My intention is a stastitical analysis of failures only. Bascially a weibull plot. The 8 seems to be off set to higher hours, but that is not significant as there are failures.

[/quote]Nothing for nothing - I'm sure we have some Bo owners/previous owners - I believe Bonanzas had a similar recurring inspection on the tail?[/quote]

As a former Bo owner, I can weigh in on this a bit. Beechcrafts were hit with several AD's, one being inspection of the spar carrythrough structure for the wing. Some high time, hard use airplanes were developing cracks in that area. The fix was horrendously expensive, the number of affected airplanes was very small. It pretty much became a non issue, with inspection required at the annual. Always sweated it a bit, but never had a problem. It never did seem to effect the resale values.

The V-tail had it's own issues, the fix for the leading edge of the ruddervators was simple and effective. But they did definitely take a hit on resale that they haven't recovered from to this day. Straight tail Bo's just command a premium.
