NTSB narrative
THE PURPOSE OF THE FLT FOR BOTH ACFT WAS AN AERIAL PHOTO MISSION. N5113S WAS USED AS THE CAMERA PLATFORM. THE PLTS OF N5113S AND N4346L DISCUSSED PRIOR TO TAKEOFF THE PROCEDURES OF THE FLT. BOTH ACFT DEPARTED AND FLEW A COURSE TO POSITION THE AIRPLANES ON A SOUTHERLY HEADING. N5113S WAS TO THE EAST AND SLIGHTLY ABOVE AND AHEAD OF N4346L. THE PHOTOGRAPHER SHOT ONE ROLL OF FILM AND RELOADED. HE WAS READY TO BEGIN SHOOTING WHEN N4346L BEGAN TO CLOSE IN ON N5113S. THE PLT OF N5113S FELT TWO 'BUMPS' AS N4346L CLOSED, AND DID NOT SEE THE ACFT PASS UNDER. THE PLT OF N5113S MANEUVERED HIS ACFT TO DETERMINE CONTROLLABILITY AND SAW N4346L SPIRALLING TO THE GROUND. EXAM OF N4346L REVEALED THE VERT STAB AND RUDDER HAD SEPARATED IN-FLIGHT. THERE WERE NUMEROUS PAINT SMEARS FOUND ON THE RIGHT SIDE ON N5113S.

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
