Accident Overview
A pilot experienced spatial disorientation and lost control of the aircraft shortly after takeoff, resulting in a crash into the Pawcatuck River. The occupants were able to egress from the sinking aircraft and swim to a nearby dock for assistance.
Weather Briefing
Before the flight, the pilot obtained weather information. No weather report was available for the departure airport, but the destination, Hartford, Connecticut, was reported as clear. While monitoring the UNICOM frequency, the pilot was informed that only ground fog was present in Rhode Island, which was not expected to affect the flight to Hartford.
Preflight Assessment
During preflight, the pilot observed the stars directly overhead and concluded that only ground fog was present. The airport elevation was 81 feet above mean sea level.
Flight Sequence
After takeoff, the aircraft climbed to approximately 200 feet MSL. At that point, the pilot suddenly realized that the fog was denser than reported or anticipated. He then experienced vertigo, described as spatial disorientation, and subsequently lost control of the aircraft.
Impact and Egress
The aircraft struck the tops of trees and crashed into the Pawcatuck River. As the aircraft sank, the occupants exited and swam to a dock, where they received help.
