Aircraft involved

Probable cause & findings

The student pilot's failure to maintain proper glidepath to the runway. Contributing factors to the accident included the passenger vehicle, the rising embankment, and the airport perimeter fence.

Factual narrative

The airplane impacted terrain while on final approach to runway 22 (3,120 feet by 24 feet, asphalt). The student pilot stated that the airplane "was caught in a downdraft/wind shear and was not able to clear perimeter fence, even with application of full power." The pilot reported there was a small valley to the northeast of the airport which "probably caused the downdraft." An on-scene investigation revealed that the airplane impacted the radio-antenna of a passenger vehicle operating on the road adjacent to the airport. The airplane then impacted a rising embankment and proceeded through the airport perimeter fence, coming to rest short of the approach threshold. The student pilot was flying with an expired 90 day solo endorsement and did not have a medical certificate. The student pilot was operating the airplane as a light-sport pilot. A local weather reporting station reported the winds were from 260 magnetic degrees at 4 knots at the time of the accident.
