Bonanza second row side window cracked - How?

Today I spotted two four inch and one six inch vertical cracks in the side
window at the seat directly behind the pilot seat. The cracks are almost
perfectly straight and originate at the top frame more or less in the middle
of the window. The aircraft is a 1973 V35B and I would imagine that this
window is that old.

How does this happen? Old age? Cold to hot? Some other force that decided
that one month since my last aviation maintenance expenditure was too long?

Answer "C" is correct.

It is probably your fault for allowing your airplane to discover excess cash
in your bank account.

I am going to guess it is temperature related.
How hot did it get in your hangar yesterday?

What side is it? Is it the green color? If you want a used one, but in good
condition, you can have it for free if you figure out how to get it from
Wisconsin. I have a set of a windshield and side windows from my 19980 Baron
B-55, which I think are the same as your Bonanza.

Replacing a whole set is around $6,000.

Is it curved (bubble-convex) ....not flat?

I would think a Shipping Store would do a good job of packing it - for a
little extra. :-)

(Box) (in a box) (in a box) each surrounded by packing peanuts. Final
(((box))) as big
as a medium size microwave (box) at Best Buy.

They might charge $45 ....Total.

Do they originate from the area around the hinges?

If they migrate to/from the hinge, I'd guess an inordinate sideload (stress
fracture).

Early in the week temperatures dipped into the lower 40s (degrees F) at
night, but the aircraft was in a community hangar that most likely doesn't
drop below 60 or so, assuming the door remained closed (this hangar located
in Buffalo, NY - where I travel during the week for work). On Thursday, the
day I departed, the temperature climbed up to around 85.

Thank you for your very generous offer, Viperdoc. The window is the left
side, just behind the pilot's seat and is the one that also acts as an
emergency exit for that row of seats. The current window is not tinted at
all.

Earlier today I called the mechanic and received a quote for US $185 for a
new one (labor extra), then just went ahead and ordered it.

In the future, though, we may be in touch.

Ha. Once again, pilot error.

Having replaced all of the windows recently, you are probably lucky that it
is the side window that opens. Regardless, the amount of work involved is
pretty extensive, and getting a good seal afterwards can be a challenge.
