NTSB narrative

Another pilot witnessed the accident. He reported that the pilot took off to the south. The aircraft began a gradual climb to approximately 50 feet agl and turned east. The witness stated that the aircraft began losing altitude about halfway through the turn. The witness stated that it did not sound as if the throttle was set at full power and opined that the pilot did not apply sufficient power to complete the turn. The aircraft impacted the ground in a nose down attitude while traveling approximately 30 miles per hour, according to the witness' estimation. The witness stated that at no time did he hear the engine cut out or stop and there did not appear to be a malfunction with the flight controls. He further reported that the pilot had flown solo approximately four times prior to the accident. At the time of writing this report, the pilot was hospitalized and in a coma. No one else was able to provide information or further details. According to the Federal Aviation Administration airman certification record files, the pilot has never held an FAA pilot's certificate.

Probable cause

The failure of the uncertificated pilot to maintain control of the aircraft.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 1999-06-19.
