NTSB narrative
The pilot did not receive a weather briefing before beginning the cross-country flight. After takeoff, the pilot requested from air traffic control to fly below 500 ft above ground level along the ocean shoreline. The controller approved the request but advised of heavy precipitation (a thunderstorm) at the airplane's 12-o'clock position and 4 miles ahead. The controller further advised that the pilot should turn left and fly offshore 3 miles to avoid the thunderstorm. Although the pilot acknowledged the instructions, a review of radar and GPS data for the flight revealed that he continued on course. About 3 minutes later, the pilot reported the he was reversing direction, and no further communications were received from the pilot. Review of the airplane's GPS track overlaid on weather radar plots revealed that the airplane flew into an area of extreme intensity precipitation and then entered a rapid descent and impacted the ocean. Examination of the wreckage did not reveal any evidence of preimpact mechanical malfunctions. It is likely that the pilot lost control of the airplane when it encountered strong downdrafts and heavy rain associated with the thunderstorm.
Probable cause
The pilot's inadequate preflight and in-flight weather planning, which resulted in continued flight into a thunderstorm and a subsequent loss of airplane control.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
