 |

Hello Listers:
To add some perspective to the discussion, attached is a scan of an
article from The American Bonanza Society magazine. I and a Pal who
monitors this list both own early Bonanzas (1948 & 1950 Models). This
article contains so many aspects about Bonanza ownership that we constantly
refer to it regarding our aircraft. Bonanzas are extrememly "clean"
aircraft in flight. When in level flight, if you just lower the nose, they
develope speed at a tremendous rate. If you then jerk back on the yoke to
recover, you can easily exceed the design limitations of the airframe. That
is probably what happened to the aircraft in the attached article. Other
aspects of this article include:
Note everyone worries about the V tails, but it was the wings and wing spar
carrythroughs that suffered damage from this high speed dive pullout.
When asked why we won't join the ABS, it's because we have so little in
common with the moneyed owners such as featured in this article.
Need a IO-550 conversion, just wave the money wand and it happens.
Need a complete structural repair with new avionics, paint & tip tanks, just
go out and whistle it up!
Total before paint etc. is 88 grand, no problem.
Anyway, that is why My Pal & myself are involved with ZA & RV's
Whenever hanger discussions turn to glass cockpits, expensive conversions,
anything top level, we refer to this article and jokingly wave the "money
wand" and say "hey just put it in", and have a good laugh as we are so far
removed from this author.
Back to the structural failure. Note that this author estimates that his
pullout from the icing induced dive exceeded 8 g's. I am just pointing out
that this same set of circumstances can probably happen in any aircraft.
Best regards,
