NTSB Narrative Summary Released at Completion of Accident
PURPOSE OF THE FLIGHT WAS TO TEST THE AIRPLANE'S RADIOS. THE PILOT'S WIFE WAS AT THE AIRPARK WITH A PORTABLE VHF RADIO. ACCORDING TO HER, THE AIRPLANE ORBITED THE AIRPARK ABOUT 5 TIMES, THEN FLEW TOWARD AN AREA THE PILOT HAD PREVIOUSLY IDENTIFIED TO HER AS A POSSIBLE FORCED LANDING AREA. SHE SAID THE PILOT CONTACTED HER & ADVISED OF A 'PROBLEM WITH THE PROPELLER.' FOUR WITNESSES SAW THE AIRPLANE MANEUVERING AT LOW ALTITUDE. THEY INDICATED THE PLANE PULLED UP FROM NEAR TREETOP LEVEL, THEN IT ENTERED A DESCENT, HIT TREES, CRASHED & BURNED. ONE WITNESS SAID THE ENGINE SOUNDED LIKE IT WAS RUNNING ROUGH; ANOTHER STATED THE ENGINE POWER STOPPED BEFORE THE AIRPLANE PITCHED NOSE DOWN. NO PREIMPACT FAILURE OF THE ENGINE WAS FOUND.
