NTSB Narrative Summary Released at Completion of Accident
BOTH ACFT INVOLVED IN THE COLLISION WERE PART OF A 4-PLANE FORMATION FLT EN ROUTE TO A GROUP FLY-IN. N6439R WAS SEEN TO CHANGE POSITIONS SEVERAL TIMES DURING THE FLT WHILE THE OTHER ACFT REMAINED STABLE. REPORTS FROM WITNESSES SAY THAT N6439R MADE 'CLOSE APPROACHES' & 'CROSS UNDERS' OF THE OTHER ACFT IN THE FLT. THE PLT OF N73708 SAID THAT FROM OFF HIS RIGHT SIDE 39R BANKED LEFT TO APPROACH HIS ACFT. WHEN THE BANK ANGLE OF 39R HAD NOT CHANGED AT 50 YDS DISTANCE, THE PLT OF 708 SAID HE STARTED A HARD EVASSIVE LEFT TURN BUT THE PROP OF 39R STRUCK THE BOTTOM OF HIS ACFT. THE VERSION TOLD BY THE PLT OF 39R WAS IN DISAGREEMENT WITH THE EVIDENCE & THE MAJORITY OF THE WITNESSES. ALL 3 OF THE 100 HR PVT PLTS SAID THEY WERE UNCOMFORTABLE WITH WHAT THE PLT OF 39R WAS DOING, BUT SINCE HE HAD A COM/CFII & 900 HRS, THEY THOUGHT 'HE KNEW WHAT HE WAS DOING.'
