Incident Overview
A student pilot conducting his first supervised solo flight was instructed by his flight instructor to perform three takeoffs and full-stop landings. After completing the second landing, the student pilot departed the traffic pattern without authorization. He did not acknowledge multiple attempts to contact him via UNICOM.
Witness Accounts
The pilot's son-in-law reported that he observed the aircraft flying over his residence and took pictures of it. Subsequently, witnesses saw the aircraft flying at a low altitude over a golf course. Moments before the crash, witnesses reported that the aircraft entered a steep left bank and then disappeared below tree level. The aircraft impacted in an adjacent field shortly thereafter.
Investigation Findings
A post-accident examination of the aircraft and engine revealed no preimpact mechanical problems. The investigation did not determine any specific mechanical or structural failure that could have contributed to the accident. The pilot's actions, including the unauthorized departure from the traffic pattern and low-altitude flight, are noted in the report but no official probable cause was assigned.
Conclusion
The incident remains a case study in student pilot behavior during early solo flight, highlighting the importance of adherence to flight instructions and communication protocols.
