The Cessna POH quoted is an old one, 1964, back in the days we did spins to get a PPL. The stalls referenced in those manuals were FULL STALLS, the nose dropped through the horizon with the yoke full back, before any effort to recover was permitted in the check ride. The standard spin that those planes were certified for were a full turn, recover wings level. That recovery could be in a dive as steep as 30 degrees, and required care to avoid high G loads.
I believe that in modern check rides, the recovery is as soon as shudder occurs. I may be wrong, and I am sure that someone will correct me if I am. The regulations have changed many times over the half century since my PPL, and my Commercial check ride did not include a real full stall.
The appearance of the wreckage seemed to me to be the result of falling at a steep angle, through the trees to the ground, not through the trees in a somewhat horizontal direction. Both wings are attached to the fuselage, not broken off. There are large trees just aft the fuselage, which would have removed the wings if traveling forward.
The damage to the wings, right wing tip bent up, left wing some crushing, would be expected if the plane descended nose up, through the limbs of the nearby trees, rather than through the clump of tree trunks, at 50 or more miles per hour, ie., flying. The engine seems to be broken off the firewall from the vertical forces in the crash.
The good news is that the occupants survived, with minor injuries. Years ago, a Cessna stalled into the trees at the end of the runway at CGS, and had similar results. The tree limbs stopped modest forward motion, and the plane descended vertically, with no severe injuries.
