Analysis

The non-instrument rated pilot encountered instrument meteorological weather conditions during a VFR flt, and requested a special VFR clearance to enter the control zone and land at the destination. Radio and radar contact with the flt was lost at 4000 ft MSL in the vicinity of the accident site. The acft impacted upsloping terrain that was obscured in clouds, near the top of a hill at 4000 ft MSL. Toxicological tests indicated that 57.7 ug/ml of a prescribed medication, quinidine, was detected in the blood; normal therapeutic concentration range in plasma is 2.0 T0 6.0 ug/ml.
