On November 21, 1996, a Piper PA-28-236 (registration N8447B) was involved in an aviation accident near Lost Hills, CA. Investigators recorded the probable cause as: The pilot's continued VFR flight into instrument meteorological conditions, which led to spatial disorientation and loss of aircraft control, and the pilot exceeding the aircraft's design stress limits during an attempted recovery. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
The aircraft was discovered with its wings and empennage detached from the fuselage. The separations were symmetrical and showed overload characteristics. Weather data indicated clouds and light rain. The pilot lacked instrument rating, recent instrument training, and did not obtain a weather briefing.
Incident Overview
The aircraft was found with its primary lifting surfaces (wings) and tail assembly (empennage) detached from the main fuselage structure. The separations were approximately symmetrical on both sides of the aircraft. Examination of the fracture surfaces determined that the separations were overload in character, meaning the structure was subjected to forces exceeding its ultimate strength.
Weather Conditions
Recorded meteorological data from the time and location of the accident indicated the presence of cloud cover and light rain near the accident site.
Pilot Information
The pilot did not hold an instrument rating. Review of the pilot's logbook revealed no recent instrument training or instrument flight experience. Additionally, there was no record of the pilot obtaining a preflight weather briefing or an in-flight weather briefing.
