spins, c of a, & regs

just a curiosity question: is anything wrong, illegal, or dangerous in
entering a c150 into a spin at 9,000' and holding full elevator to
maintain it down to 2000 before recovering since spins are often
prohibited at lower altitudes?

First of all, is your Cessna 150 legal for spins? (It depends on how the rudder
AD was complied with on your plane)

I guess it was, it was a school plane in the early 60's.

Unfortunately that rudder AD only came out a few years ago and affected
swept-tail C-150s and 152s even if they had previously been successfully
spun for years. Here is a news article on it:

They had to fixed or placarded against spins. So if plane isn't placarded
against spins you can probably do it.

Here's a video of a C-152 being put into a 15 turn spin from 6000 to 3000:

Don't try spins without instruction on recovery.

Interesting article, I haven't read anything about 150's for decades!

I'll side with Cessna on the issue though because an agressively sought
prespin stall begins near 90 degrees nose up and CAN lead to a short
tailslide which could bend a rudder. Just a hunch..

I'll just presume that the back seat is full of other 'students' :-)

Gee that sounds like fun! My spin instructors never liked spinning
*that* much. That said, only had two instructors that were into
teachign me spin recovery. It was not *manditory* when I did my PPL in
NZ - and don't believe it is still. However I think it's near essential
to learn - as well as a chitload of fun. I asked to do spin recovery
under the hood - which was a heap of fun too. And it was great to be
able to suceed in doing it.

Others have answered your questions about the plane - is it approved for
spinning etc. Only other comment is that it may not be that wise to
recover by 2,000'??? - I was always taught to recover by 3,000' AGL. I
guess that's really an instructor/club thing - and therefore where you
should direct your question.

You'll be spining with an instructor anyway right? (dual?). In NZ you'd
need to be approved for aerobatics (and that particular manoeuvre) to
spin solo.

Gee, how times have changed! In my formative days(late !940's) you didn't
solo until you were able to recover from spins in both directions. Before
the ppl, we did recovery from unusual attitudes, needle, ball and airspeed
navigation, all under the hood. And it was all fun!

And it was all useful! Mind you in all this time I never once entered a
single unintentional spin. The others were fun though, sorta breaking
the monotony :-)

The reason I asked the original Q was from watching an rv8 or Team-F1
spin recovery clip on utube and I noticed that recovery was always
withing a turn or two. That's very good of course, half a turn is even
better, but I just wondered if there might not be some seldom advertised
taboo about extended spins.

What were you flying? - the Tigermoth? or Stearman?
