Incident Overview
The pilot obtained a complete weather briefing approximately 30 minutes prior to a nighttime takeoff. Despite the briefing, the pilot chose to depart under visual flight rules (VFR) without filing a flight plan into an area where thunderstorms were present. Subsequently, the airplane flew into a bay of the Gulf of Mexico, located about 29 miles from its departure point.
Weather Briefing and Departure
The preflight weather briefing provided the pilot with information about thunderstorm activity. About half an hour after the briefing, the pilot initiated the takeoff at night. The flight was conducted under VFR and without a flight plan, and the route took the aircraft directly into the thunderstorm area.
Radar and Wreckage Examination
Recorded radar data and an examination of the wreckage indicated that the aircraft was in a descending right turn just before it impacted the bay. Investigators found no evidence of a mechanical problem with the aircraft prior to impact. The examination did not reveal any preimpact failure or malfunction.
