The NTSB's narrative final · quoted from the NTSB record
AT O634 MST, THE PILOT FILED A VFR FLIGHT PLAN & RECEIVED WEATHER INFO FOR A ROUTE FROM EL PASO TO TUCSON. HE WAS ADVIZED OF 2 PIREPS REGARDING SEVERE TURBULENCE IN THE TUCSON AREA & OF AN AIRMET CONCERNING TURBULENCE BELOW 12000 FT. THE PILOT'S TAKEOFF & DEPARTURE APPEARED NORMAL, THEN THERE WAS NO FURTHER COMMUNICATION WITH THE AIRPLANE. WHILE EN ROUTE, AN IN-FLIGHT BREAKUP OF THE AIRCRAFT OCCURRED, BUT THERE WERE NO KNOWN WITNESSES. THE RIGHT OUTBOARD WING PANEL WAS FOUND ABOUT 2/10 MILE FROM THE MAIN WRECKAGE WITH EVIDENCE THAT IT HAD FAILED IN POSITIVE (UPWARD) LOADING. THE OUTBOARD 2/3 OF THE LEFT HORIZONTAL STABILIZER HAD SEPARATED, BUT WAS NOT FOUND; THERE WAS EVIDENCE THAT IT HAD FAILED DOWNWARD. A PARK RANGER NOTED THE PRESENCE OF A 'BLACK . . . DOME SHAPED' CLOUD OVER MOUNTAINS ABOUT 5 MI FROM THE CRASH SITE. IT WAS CAPPED WITH ANOTHER SMALLER CLOUD AT A HIGHER ELEVATION. THE NATIONAL WEATHER SERVICE HAD NOT ISSUED AN ADVISORY FOR SEVERE TURBULENCE, ALTHOUGH INFO FOR SUCH DETERMINATION EXISTED BEFORE THE FLIGHT.
