What happened
The flight involved a private pilot who was not rated for instrument flight. Prior to departure, the pilot obtained a standard weather briefing which clearly indicated that conditions were expected to deteriorate into Instrument Meteorological Conditions (IMC). Despite this explicit warning, the pilot elected to proceed with the flight.
During the en route phase, the pilot lost situational awareness and became spatially disoriented. The aircraft penetrated two separate control zones while the pilot attempted to maintain visual reference in conditions that required instrument flying. While attempting to remain Visual Flight Rules (VFR) despite being inside IMC, the aircraft struck an antenna guy wire.
The investigation
The investigation focused on the pilot's decision-making process and the environmental conditions at the time of the accident. Evidence confirmed that the weather briefing provided prior to flight accurately reflected the deteriorating forecast. The physical evidence of the impact with the antenna guy wire confirmed the loss of control associated with spatial disorientation.
Findings
The primary contributing factors were the pilot's lack of instrument rating and the decision to continue flying into known IMC conditions. The pilot's inability to maintain visual reference led to spatial disorientation, which directly resulted in the collision with the antenna guy wire.
