NTSB Narrative Summary Released at Completion of Accident
THE STUDENT PLT WAS THE OWNER/OPERATOR OF THE ACFT. HE AND THE PASSENGER WERE ON A PLEASURE FLT IN AN AREA OF MOUNTAINOUS TERRAIN. THE ACFT WAS SEEN TO TURN INTO A VALLEY WHERE IT SUBSEQUENTLY COLLIDED WITH THE GROUND AT AN ELEVATION OF ABOUT 5500 FT. DURING IMPACT, THE WINGS WERE BENT DOWN AND FORWARD; THERE WAS A 45 DEG CRUSH LINE ON THE LEADING EDGES OF THE WINGS. NO GROUND SCARS WERE FOUND TO INDICATE MOVEMENT AFTER GROUND IMPACT. THE ACFT'S LAST ANNUAL INSPN WAS DATED 7/22/87; HOWEVER, THE STUDENT PLT CONTINUED TO OPERATE THE ACFT; HE PERFORMED OIL CHANGES HIMSELF. NO PREIMPACT MECHANICAL FAILURE OR MALFUNCTION OF THE ENGINE WAS FOUND. THE STUDENT'S LAST MEDICAL EXAM WAS DATED 11/25/87. A TOXICOLOGY EXAM OF THE STUDENT PLT'S BLOOD SHOWED A SATURATION OF 20% CARBOXYHEMOGLOBIN. A FLT SURGEON REPORTED THAT THIS PERCENTAGE COULD CAUSE A HEADACHE, A STATE OF CONFUSION, DIZZINESS AND VISUAL DISTURBANCE. THE INVESTIGATION DID NOT DETERMINE IF THE ACFT HEATER SYSTEM COULD HAVE BEEN THE SOURCE OF CARBON MONOXIDE.

IMPROPER INFLIGHT PLANNING/DECISION BY THE STUDENT PILOT (PILOT-IN-COMMAND), AND HIS FAILURE TO MAINTAIN ADEQUATE AIRSPEED, WHICH RESULTED IN A STALL. FACTORS RELATED TO THE ACCIDENT WERE: PHYSICAL IMPAIRMENT OF THE STUDENT PILOT/OWNER/OPERATOR FROM CARBON MONOXIDE, MOUNTAINOUS TERRAIN, AND HIGH DENSITY ALTITUDE.
