NTSB narrative
OPENING ACT WAS FOR 3 JUMPERS TO EXIT FROM JUMP-PLANE (J/P) AT 3500' AGL; 2 JUMPERS WERE TO JOIN AT 2000' TO DISPLAY FLAG, WHILE 3RD JUMPER WAS TO CIRCLE ABOVE. N90BC & N31485 WERE TO CIRCLE JUMPERS IN OPPOSITE DIRECTIONS. N90BC WAS TO CIRCLE CLOCKWISE, OUTSIDE TURN RADIUS OF N31485, WHICH WOULD CIRCLE COUNTERCLOCKWISE. WHEN 2 OF 3 JUMPERS EXITED FROM J/A, PILOT OF N31485 BANKED LEFT INTO SPIRAL, APPARENTLY UNAWARE OF 3RD JUMPER. 3RD JUMPER DELAYED UNTIL N31485 WAS CLEAR, THEN JUMPED AS J/A CONTINUED ON SAME HEADING. PHOTO SHOWED N90BC WAS TO THE RIGHT & AT AN UNDETERMINED DISTANCE BEHIND N31485 AS 1ST 2 JUMPERS EXITED. AFTER 3RD JUMPER EXITED, HE & N90BC COLLIDED. N90BC WAS DAMAGED, WENT OUT OF CONTROL & CRASHED. AFTER ACCIDENT, SOME PARTICIPANTS OF PRESHOW BRIEFING DID NOT RECALL A 3RD JUMPER BEING MENTIONED, ALTHOUGH OTHERS REMEMBERED. 3RD JUMPER WAS NOT PRESENT FOR PRESHOW BRIEFING, BUT AC 91-45C ALLOWED FOR ONLY 1 MEMBER FROM EACH TEAM TO ATTEND PRESHOW BRIEFING, THEN BRIEF OTHER TEAM MEMBERS.

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.
