What happened
The pilot, who was not instrument-rated, departed on a cross-country flight under visual flight rules (VFR) during nighttime conditions. Upon receiving weather information along the intended route, the pilot requested and received radar advisories from air traffic control. Shortly after takeoff, the pilot reported encountering a storm. For approximately ten minutes, the radar controller maintained communication with the pilot, providing assistance while the pilot described terrible weather conditions and bad turbulence.
During this period, the passenger began transmitting on the radio for the pilot. The passenger stated that they were in serious trouble and attempting to maintain straight and level flight. The final transmission from the aircraft indicated an altitude of 2000 feet with significant vertical movement. A local farmer was awakened by the sound of the aircraft circling his house. He observed the aircraft climbing and diving before it crashed. The aircraft subsequently impacted rising ground in an area characterized by rolling terrain. Witnesses reported that wind was blowing and rain was falling at the time of the incident.
The investigation
Examination of the wreckage revealed no pre-impact mechanical malfunctions or failures of the aircraft. The impact occurred in difficult terrain conditions with poor weather visibility.
Findings
The pilot's decision to continue flight into known severe thunderstorms while operating under VFR at night contributed to the loss of control. The presence of bad turbulence and low visibility prevented the pilot from maintaining situational awareness. Controlled flight into terrain occurred as a result of these conditions.
Safety message
Pilots should not attempt to fly visual flight rules at night into known severe weather without appropriate instrument ratings and equipment. Radar advisories do not constitute clearance to enter hazardous weather conditions.
