NTSB Narrative Summary Released at Completion of Accident

THE NON-INSTRUMENT RATED PLT OBTAINED A WX BRIEFING & FILED AN IFR FLT PLAN ALTHOUGH POOR WX CONDITIONS EXISTED (200 FT CEILING & ONE-HALF MI VISIBILITY) AT SAN ANTONIO. THE TOWER INSTRUCTIONS TO N5681K WERE TO FLY RWY HEADING (120 DEG) AFTER DEPARTURE, HOWEVER, WHEN THE ACFT MADE A LEFT TURN AFTER TAKEOFF, THE ACFT WAS INSTRUCTED TO TURN RT TO A HEADING OF 180 DEG. THE PLT ACKNOWLEDGED THE HEADING CHANGE BUT DID NOT COMPLY WITH THE INSTRUCTIONS. THIS WAS THE LAST CONTACT WITH THE PLT. DURING THE INVESTIGATION A COMPUTER-GENERATED GROUND TRACK REVEALED A LEFT TURN OF 495 DEG, FOLLOWED BY RT TURN OF 45 DEG WHICH WAS HELD FOR ABOUT ONE-HALF MIN & THEN ANOTHER RT TURN OF ABOUT 50 DEG BEFORE DISAPPEARING FROM RADAR.
