The 172 N Model I fly from time to time is only approved (and thus was

Though it may be recovered from a spin when loaded within the normal
category range, it was not certificated that way. Which tells me there
is no assurance of recovery.
BULL****!!

Section 23.221: Spinning.
(a) Normal category airplanes. A single-engine, normal category airplane
must be able to recover from a one-turn spin or a three-second spin,
whichever takes longer, in not more than one additional turn after
initiation of the first control action for recovery, or demonstrate
compliance with the optional spin resistant requirements of this
section.

(1) The following apply to one turn or three second spins:

(i) For both the flaps-retracted and flaps-extended conditions, the
applicable airspeed limit and positive limit maneuvering load factor
must not be exceeded;

(ii) No control forces or characteristic encountered during the spin or
recovery may adversely affect prompt recovery;

(iii) It must be impossible to obtain unrecoverable spins with any use
of the flight or engine power controls either at the entry into or
during the spin;

I would suggest that you read the entire FAR section 23.221 for Normal,
Utility, and Aerobatic category aircraft.

I've read the FARs.

I've also read the POH, which states "Spins approved when loaded
within utility category."

I'll see your Bullchip and raise you three chickships.

But you said your 172N hadn't been tested when in the utility
configuration. 23.221 pretty much shows that is not the case. There is a
difference in approved and tested.
