PARACHUTE JUMPING NEAR SID DEP RTE ONT.

Narrative

DEPARTED ONT ON SCHEDULED FLT TO DFW. WHILE ROLLING OUT OF TURN JUST BEYOND NIKKL ON PRADO 2 DEP; NOTICED TFC ABOVE AT 11 O'CLOCK ON TCASII DISPLAY. ACQUIRED TFC VISUALLY AND POINTED OUT TO THE PNF. VISUALLY ACQUIRED TFC AT 5-7 MI. THEN QUICK SEQUENCE SAW JUMPER(S) DEPART TFC ACFT; HAD TFC CALLED BY ATC (FIRST MENTION OF TFC); TCASII CALLED 'TFC; TFC' FOLLOWED BY 'DSND; DSND.' AT THIS TIME TFC WAS AT 09:30-10 O'CLOCK; 1-2 MI. AFTER SLIGHT DELAY DUE TO THINKING WE WERE CLOSE BUT CLR OF SUBJECT TCASII TFC; I SMOOTHLY RETARDED PWR AND BEGAN DSCNT (TCASII WAS LOUDER; MORE INSISTENT). NOTE THAT FLT ATTENDANTS WERE UP BEGINNING SVC AND PAXS MAY HAVE BEEN UP -- SEAT BELT SIGN OFF WITH SMOOTH AIR ABOVE 10000 FT MSL. AFTER ENTERING SHALLOW DSCNT TCASII ANNOUNCED 'CLR OF CONFLICT' AND WE RESUMED CLB ON DEP. SHORTLY AFTER THE INCIDENT ONTARIO APCH CTL SWITCHED US TO LOS ANGELES CTR. UPON QUESTIONING; LA CTR SAID BOTH THEY AND ONTARIO APCH HAD THE JUMP ACFT ON RADAR. A PHONE CALL TO AN ONTARIO APCH SUPVR AFTER LNDG IN DFW REVEALED THE EXISTENCE OF A JUMP ZONE 2-3 MI N OF V64; JUST PAST NIKKL ON THE PRADO 2 DEP. THE CLOSE PROX OF JUMP ACFT AND JUMPERS TO ONTARIO DEPS ON THE PRADO 2 OCCURS REGULARLY. THE JUMP ACFT IS REQUIRED TO HAVE THE DEPARTING ACFT IN SIGHT BEFORE RELEASING HIS JUMPERS. WE WERE NOT ADVISED OF THE ACFT OR JUMPERS UNTIL WE WERE SO CLOSE THAT OUR 325 KIAS SPD AT 14-15000 FT MSL WOULD HAVE MADE AVOIDANCE DIFFICULT. JUMPERS AND THEIR ACFT WOULD HAVE A DIFFICULT TIME AVOIDING US DUE TO OUR AIRSPD EVEN IF THEY HAD US IN SIGHT. THERE IS NO MENTION OF THIS DROP AREA ON THE DEP PLATE (ALTHOUGH A DROP AREA ABOUT 8 MI S OF NIKKL IS NOTED) OR IN ANY NOTAM. THE FACT THAT THIS SITUATION IS INHERENTLY DANGEROUS IS OBVIOUS. THE MORE MANEUVERABLE ACFT APCHING THE JUMP AREA AT SUCH A HIGH SPD MUST BE GIVEN ADEQUATE NOTICE TO AVOID THE JUMPERS AND JUMP ACFT. THERE IS NO EXCUSE FOR NOT VECTORING DEPARTING ONTARIO TFC CLR OF THIS JUMP ZONE. IF THE PRADO 2 DEP IS TO BE USED WHEN THE JUMP ZONE IS ACTIVE IT SHOULD BE REDESIGNED TO AVOID THE ZONE BY MORE THAN 2-3 MI; AND THE DEP PROC SHOULD WARN OF JUMP ACTIVITY IN THIS AREA. WARNINGS VIA NOTAM AND VIA EARLY TFC CALLS BY APCH CTL; AND VECTORING CLR OF JUMP ACFT CAN AND SHOULD BEGIN TODAY!
