ON DECEMBER 11, 2021, AN EXPERIMENTAL AMATEUR-BUILT RV-3 AIRPLANE, N9YY, WAS SUBSTANTIALLY DAMAGED AND THE PILOT WAS FATALLY INJURED. ACCORDING TO THE PILOT'S FRIEND, THE PILOT PLANNED A LOCAL FLIGHT WITH THE INTENTION OF OVERFLYING THE PILOT?S HOME. A WITNESS LOCATED ABOUT A MILE WEST OF THE ACCIDENT SITE OBSERVED THE AIRPLANE IN A DESCENDING RIGHT TURN, ABOUT A FEW HUNDRED FEET FROM HER LOCATION. SHE RECALLED SEEING THE PROPELLER WIND MILLING. A SECOND WITNESS STATED AT A VERY LOW ALTITUDE. HE OBSERVED THE AIRPLANE ROLL UNTIL ONE WING POINTED STRAIGHT UP AND THE OTHER POINT STRAIGHT DOWN. THE AIRPLANE THEN DESCENDED IN A STEEP NOSE DOWN ANGLE. THE AIRPLANE CAME TO REST UPRIGHT IN A RESIDENTIAL DRIVEWAY. THE FIRST POINT OF IMPACT WAS A PALM TREE LOCATED ADJACENT TO A PRIVATE HOME. ALL MAJOR COMPONENTS OF THE AIRPLANE WERE IN THE DEBRIS AREA OF ABOUT 30 FEET BY 30 FEET.
