Investigator assessment
Analysis narrative
The student pilot stated he departed from his remote cabin and recalled experiencing significant downdrafts while maneuvering in an area of hilly terrain. The next thing he remembered is trying to turn off the key after the accident, and then waking up in a hospital. The fuselage and both wings sustained substantial damage. During a postaccident interview with a Federal Aviation Administration inspector, the pilot stated there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation. The pilot did not submit the National Transportation Safety Board Pilot/Operator Aircraft Accident/Incident Report Form 6120.1.
