The NTSB's narrative final · quoted from the NTSB record

PILOT WAS REPORTED MISSING APRX 4 DAYS AFTER HE HAD DEPARTED FOR MADELINE ISLAND. AN AIR SEARCH WAS NOT SUCCESSFUL IN LOCATING THE AIRPLANE AND PILOT. ABOUT 3 MONTHS LATER, ON 11/17/90, THE WRECKAGE WAS FOUND. THE AIRPLANE HAD IMPACTED THE GROUND AT A HIGH IMPACT ANGLE AND AT A HIGH IMPACT SPEED. THE PILOT'S WIFE TOLD INVESTIGATORS THAT HE 'LOVED TO GO TO MADELINE ISLAND AND DRINK.' WITNESSES REPORTED THAT THE PILOT WAS LAST SEEN IN A BAR AT 0100 CDT, AND THAT HE APPEARED TO BE QUITE INTOXICATED. THE PILOT ASKED SEVERAL PEOPLE FOR A RIDE TO THE AIRPORT, BUT NONE RECALLED SEEING HIM LEAVE THE BAR. THE AIRPLANE WAS NOT OBSERVED AT THE MADELINE ISLAND AIRPORT LATER THAT MORNING. THE PILOT'S MEDICAL CERTIFICATE HAD A LIMITATION AGAINST NIGHT FLYING DUE TO COLOR BLINDNESS AND REQUIRED CORRECTIVE LENSES FOR NEAR VISION. THERE WERE NO GLASSES LOCATED IN THE WRECKAGE.
