N9593UGrumman American Avn. AA-5A · 1976

The pilot had planned for a 40-minute scenic local flight with 3 passengers aboard. The pilot was demonstrating an aerodynamic stall when the right wing "dropped very quickly." He attempted to recover and applied opposite rudder, reduced the airplane's pitch, and increased engine power. The airplane then entered a flat spin to the right. The pilot continued to attempt to decrease the airplane's pitch and continued left rudder application, but the airplane continued to spin. The pilot then applied "full back elevator" as the airplane impacted terrain. During the impact the airplane's right wing, horizontal stabilizer, and fuselage were substantially damaged. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
