Hmmm, the Warriors I'm familiar with are placarded:a Warrior actually spins just fine, and recoveries are a non-event.
"...SPINS ARE PROHIBITED FOR NORMAL AND UTILITY CATEGORY."
Which doesn't leave much room for doubt as to their approved maneuvering limitations. This would be a situation where a wise pilot would read and abide by the limitations placard in the cockpit, rather than a quasi anonymous post read on the internet!
I am aware that some PA-28's are approved for intentional spinning, the best way to know for sure is to read the limitations placard. I very certainly would not present yourself for a flight test for which spinning is a required maneuver, in a "spins prohibited" airplane. It makes you look rather unprofessional. It is funny to see the quizzical expressions on the examiner's face when you propose to spin a "spins prohibited" plane, but then not so funny to see that the examiner is suddenly checking a box on a form which you would rather not have been checked!
Understanding the maneuver limits of the plane you're flying is one of the piloting and licensing requirements.
