## Probable cause

The pilot's failure to maintain adequate airspeed while maneuvering in the traffic pattern, which resulted in an aerodynamic stall/spin. Also causal was the failure of the left magneto due to improper assembly of the drive gear during installation on the engine, and the improper internal timing of the right magneto due to inadequate maintenance that reduced the ability of the magneto to produce an adequate spark, resulting in a partial loss of engine power.
