Circumstances
According to the investigation, the pilot and passenger arrived at the airport at approximately 1820 Eastern Standard Time. The pilot initially requested a Special VFR clearance, but that clearance could not be approved. Subsequently, the pilot requested an IFR flight plan, but attempts to activate it were unsuccessful due to communication line problems.
Decision to Fly VFR
The pilot then decided not to file a flight plan. She stated that, based on forecasts of improving conditions to the west and visibility reports of three to five miles from the tower, she planned to proceed under Visual Flight Rules (VFR). Her intended route followed the interstate highway to the south and then to the west.
Flight and Impact
During the flight, the pilot reported flying below the cloud bases, which she estimated were at 800 to 900 feet. Prior to reaching Interstate 22, while in straight and level flight, the aircraft unexpectedly impacted trees.
Investigation Findings
The investigation noted the sequence of events and the pilot's statements. No other causal or contributory factors were specified in the source material.
