What happened
On the morning of the accident, the pilot obtained a complete weather briefing from a Flight Service Station (Fly Service Station). During this briefing, the pilot was informed of the presence of icing and moderate turbulence along the planned route, as well as forecasts for scattered thundershowers. The briefer recommended that the pilot contact them for a weather update immediately before takeoff.
Approximately three hours after the initial briefing, the pilot began the flight without requesting a follow-up weather report. Following a 15-minute delay, the pilot received IFR clearance and began the journey toward the destination. During the cruise phase at an altitude of 16,000 feet, roughly 35 minutes into the flight, the pilot communicated via radio that the aircraft was experiencing significant turbulence while flying through clouds. Shortly after this transmission, the pilot reported that the aircraft was in a dive. The aircraft subsequently struck the ground in an inverted, nose-down position, resulting in an explosion.
Findings
Data retrieved from meteorological records and radar analysis revealed that the aircraft encountered a thunderstorm characterized by strong updrafts, downdrafts, and turbulence.
