NTSB Narrative Summary Released at Completion of Accident

WITNESS STATEMENTS & EXAMINATION OF THE WRECKAGE REVEALED THAT THE AIRCRAFT STRUCK THE GROUND AS A RESULT OF A STALL-SPIN TYPE ACCIDENT NEAR THE END OF THE CLOSED PORTION OF A BOX CANYON ABOUT 200 FEET BELOW THE TOP OF THE RIDGE. THE INVESTIGATION REVEALED THAT THE PILOT/BUILDER EXTENSIVELY MODIFIED THE AIRCRAFT AS BUILT FROM THE ORIGINAL PLANS/SPECIFICATIONS. ALL OF THE MODIFICATIONS ATTEMPTED BY THE PILOT WERE, ACCORDING TO THE AIRCRAFT DESIGNER, PROVEN TO INDUCE LONGITUDINAL STABILITY PROBLEMS DURING FLIGHT TESTING OF THE PROTOTYPE AIRCRAFT. THE PILOT COMMENTED TO HIS ASSOCIATES THAT HE WOULD EXPERIENCE CONTROL PROBLEMS IN TURBULENCE, REPORTEDLY SAYING THAT 'IN TURBULENCE THE NOSE WOULD COME UP ALMOST VERTICAL.' WINDS AT 30 KNOTS WITH GUSTS TO 40 KNOTS WERE REPORTED IN THE CANYON BY FOREST SERVICE PILOTS IN ADDITION TO MODERATE TURBULENCE.
