Analysis

The plt was scheduled to perform aerobatics in an air show. While maneuvering at about 300 ft AGL, the acft entered a nose high, steep left turn, stalled, then entered a 2 turn spin to the left. The plt recovered in a nose low, wings level attitude, but the acft impacted trees & the ground. No pre-impact part failure or malfuction was found. An investigation revealed the plt had started wearing soft contact lenses to correct her vision. No contact lenses were found in the wreckage & no lenses were noted in the medical examiners investigation. A pair of eye glasses were found in a bag in the cockpit.
