What happened
During the flight, the pilot contacted Vero Beach Tower to request current weather conditions. Controllers advised that Visual Flight Rules (VFR) conditions prevailed at both Vero Beach and Fort Pierce, Florida. However, they warned of weather north of Vero Beach, noting an active convective SIGMET and thunderstorms in the vicinity. The pilot acknowledged the transmission and indicated his position near the Valkaria Airport.
Shortly thereafter, the pilot reported that he had overflown the Valkaria airport and intended to proceed south toward Vero Beach. Approximately four minutes later, he advised controllers he was north of Vero Beach in Instrument Flight Rules (IFR) weather conditions. He stated he would reverse course and return to Valkaria. The pilot's final radio transmission occurred at 1820 EDT.
The following morning, aircraft wreckage was located in the same vicinity where the plane had impacted the Intercoastal Waterway. An examination of the debris field revealed the aircraft had crashed in a near inverted, nose-down attitude with the left wing low. Intense thunderstorms, lightning, and heavy showers were reported in the area at the time.
The investigation
A thorough examination of the recovered wreckage was conducted to determine the sequence of events and potential mechanical issues. Investigators found no evidence of a preimpact mechanical malfunction or failure of any aircraft component that would have hindered normal operation.
