NTSB narrative
THE PILOT WAS ADVISED OF INSTRUMENT METEOROLOGICAL CONDITIONS AND MODERATE TURBULENCE ALONG HIS PROPOSED ROUTE OF FLIGHT DURING HIS PRE-DEPARTURE WEATHER BRIEFING FROM THE AFSS. WHILE EN ROUTE, THE PILOT CONTACTED THE AFSS REQUESTING UPDATED WEATHER FOR HIS ROUTE OF FLIGHT. THE AFSS SPECIALIST ADVISED THE PILOT THAT VFR FLIGHT WAS NOT RECOMMENDED THROUGHOUT THE AREA. THE PILOT DID NOT RESPOND TO THE SPECIALIST'S RADIO CALL. FAA CENTER RADAR SHOWED THE AIRPLANE FLYING ON A NORTHWESTERLY HEADING AT 10,400 FEET MSL WHEN THE PILOT CALLED THE AFSS. SHORTLY AFTER THE CALL, THE RADAR DATA SHOWED THE AIRPLANE PERFORM A RIGHTHAND 180 DEGREE TURN AND BEGIN A DESCENT. THE LAST RADAR ALTITUDE WAS 7,800 FEET MSL. THE WRECKAGE TRAIL WAS APPROXIMATELY 1 1/8 MILE LONG HEADING FROM NORTH TO SOUTH. UPPER AIR TEMPERATURES FROM THE GOES SATELLITE WERE ZERO DEGREES CENTIGRADE BETWEEN 10,300 AND 10,600 FEET MSL. THE PILOT'S LAST LOGGED FLIGHT BY REFERENCE TO INSTRUMENTS WAS MARCH 24, 1992.
Probable cause
the pilot's decision to continue flight into known adverse weather and exceeded the design strees limits of the airplane. Factors associated with the accident were inadequate preflight planning/preparation, clouds, turbulence, icing conditions, and the lack of recent instrument experience.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
