AOPA has a good article called: Stall/spin: Entry point for crash and burn?

In 1949 the FAA removed the requirement for spin training for private pilots, substituting increased training in stall recognition and recovery, since spins cannot occur without a stall. After the elimination of the spin requirement for private pilots, the incidence of stall/spin accidents actually decreased substantially.
In reviewing 44 fatal stall/spin accidents from 1991 - 2000 and classified as instructional, the Air Safety Foundation found that a shocking 91%(40) of them occurred during dual instruction, with only 9% (4) solo training flights.
The biggest problem is where stall/spin accidents occur. Up high, time to recover. In the pattern, no.
