Accident Details
A non-instrument rated pilot departed on a local flight under visual flight rules (VFR). The departure occurred about 1400 local time. The airport weather at departure was reported as a ceiling of 12,000 feet with 10 miles visibility. About 1.7 hours after departure, witnesses observed the airplane flying south towards the shoreline at approximately 700 feet above ground level. The airplane was seen entering and exiting clouds. Upon reaching the shoreline, the airplane turned east, paralleled the coast, and reentered the clouds.
Wreckage Examination
The airplane was found submerged in water, about one mile further east from the point where it was last observed entering the clouds. Examination of the wreckage revealed no pre-impact failure of the airframe or engine.
Weather Conditions
The departure airport had instrument flight rules (IFR) conditions until 1200, but by the time of departure at 1400, conditions had improved to a 12,000-foot ceiling and 10 miles visibility. However, about 1500, the airport weather returned to a 200-foot ceiling and 3/4 mile visibility. There was no record of the pilot obtaining a weather briefing or filing a flight plan.
