Accident Overview
The accident occurred when a pilot departed in a general aviation airplane late at night into marginal visual flight rules (VFR) weather conditions. The pilot did not receive a weather briefing before departure and was not instrument rated. Radar data, meteorological reports, and witness statements indicated that the airplane subsequently entered an area containing clouds, rain, and moderate turbulence, all of which had been forecast.
Witness Observations
Before departure, a witness noted that the pilot looked “a little tired.” The same witness reported that there was no indication of any mechanical problem with the airplane.
Radar and Weather Data
Recorded radar data showed the airplane had entered a rapid descending turn from approximately 5,700 feet mean sea level (MSL). Shortly thereafter, radio and radar contact were lost. The airplane experienced an in-flight breakup, with wreckage scattered over a three-quarter mile area.
Wreckage Examination
Examination of the fracture surfaces revealed that the stabilators and left wing failed from overload in a downward direction, the right outboard wing panel failed upward from overload, and the vertical stabilizer failed to the right from torsional loads. The airplane had been recently stripped and repainted; however, no pre-accident mechanical deficiencies were found.
