Subject: | Re: Bonanza Nose Bowl replacement |
A friend of mine, restoring a B model Bonanza, split his nose bowl horizontally
at the bottom of the Air inlets. He then fabricated a strong system that reattaches
it. This way he could get the engine in and out easier.
Having said that he is about the best mechanic I know. He has the engineering data
worked up and has been told that approval should be no problem. It added a
small amout of weight.

Good Morning Steve,
It appears that your friend is reinventing the wheel!
Beech splits the nose bowl cowl on their factory turbocharged airplanes for
the same reason. They do it about in the middle of the bug eyes. I would tend
to duplicate what Beech has done if I wanted to split mine.
Happy Skies,

Subject: | Re: Bonanza Nose Bowl replacement |
The nosebowl on my V35B has a center section that is riveted to the remaind
er using doubler plates. I think this is probably the same on all models w
ith the IO-520 engine. It would be quite easy to drill out the rivets, whi
ch would allow lifting the engine almost straight upwards instead of the ex
treme tilting that is now required. The rivets could be replaced with nutp
lates and screws which would allow for future removal of the top nosebowl p
iece. This is how the T-34 nosebowl is built if I'm not mistaken. Of cour
se this would require a field approval and 337 form as this probably goes b
eyond what constitutes a minor modification. I'm really surprised that som
eone has not obtained a multiple STC for this modification.

Subject: | Re: Bonanza Nose Bowl replacement |
Good Afternoon Cliff,
Sounds like you have one of the old style nose bowls that were modified at
the factory to accommodate the canted engine starting with the S35.
Once they ran out of the old ones, that upper section was no longer used and
the nose bowl was once again a one piece item with the exception I mentioned
earlier. In those factory turbocharged airplanes, they split the nose bowl on
each side about half way from the top to the bottom of the air inlets. The
flange was riveted to one half and screwed to the other to provide easy
removal for engine changes..
Once again, why reinvent the wheel?

Hi Cliff,
I think I would consider doing it as a minor alteration on my own airplane,
but I am not so sure I would want to send one out of the shop that way.
There are some fights I don't mind fighting and others where I would sooner
not compete!
Gotta think on that one some more.

That's pretty much the way I feel about it. I just thought that if the fac
tory did that very thing on essentially the same model plane and part (with
the IO-520 engine), you could reason (and argue if need be) that it was a
minor mod.
Thanks for your input.

OK, OK When I called my buddy up he told me that he modeled his mod on the later
model. Said it sure made it easier putting the engine in.
I thot this list was dead. Take a little trip to the middle east and a lot of things
change. Where else are Bonanza discussions going on?
I just moved mine to Boerne Stage Airport NW of San Antonio. Waiting on a hanger.
