Narrative:

I was PF. I loaded the FMS as per flight plan from jfk. We were given the jfk runway 9 departure with the breezy point climb for eventual radar vectors for rbv (robbinsville) VOR. I loaded the FMS for the jfk runway 9 to cri. Then I loaded the cri 223 degree radial to 50 DME with a route discontinuity; then rbv and flight plan route. Captain double checked the FMS. Sometime before departure/pushback we were distraction with an unruly passenger. We offloaded the passenger; pushback; taxi and got in a long lineup of departures. Eventually we took off from runway 31R. Made the left turn direct cri inside the cri 039 degree radial. I was hand flying with the mode control panel in LNAV mode. I followed the flight director and over or just past cri departure control told us to turn left and intercept the cri 223 degree radial. He gave us a heading of 190 degrees. Somehow or somewhere along the line the cri 223 degree radial and route discontinuity was removed/dropped out of the FMC and we were going direct from cri to rbv; about a 240-245 degree heading. We corrected left to 190 degrees as per ATC instructions; manually intercepted the cri 223 degree radial and shortly thereafter were given direct rbv. I believe we overflew the cri 223 degree radial by 1/2 to 1 mi before turning back to 190 degrees to reintercept the cri 223 degree radial. I truly do not know if this was caused by faulty FMC loading or a wrong button push either before pushback or on taxi-out with numerous distrs; or a wrong button push on departure; or an FMS/FMC anomaly. Next time and in all future departures I will double and triple check FMC loading and backup radials manually.

Title: A B757 FLT CREW FLYING THE KENNEDY 9 DEP DEVIATED FROM THE PUBLISHED TRACK.

Narrative: I WAS PF. I LOADED THE FMS AS PER FLT PLAN FROM JFK. WE WERE GIVEN THE JFK RWY 9 DEP WITH THE BREEZY POINT CLB FOR EVENTUAL RADAR VECTORS FOR RBV (ROBBINSVILLE) VOR. I LOADED THE FMS FOR THE JFK RWY 9 TO CRI. THEN I LOADED THE CRI 223 DEG RADIAL TO 50 DME WITH A RTE DISCONTINUITY; THEN RBV AND FLT PLAN RTE. CAPT DOUBLE CHKED THE FMS. SOMETIME BEFORE DEP/PUSHBACK WE WERE DISTR WITH AN UNRULY PAX. WE OFFLOADED THE PAX; PUSHBACK; TAXI AND GOT IN A LONG LINEUP OF DEPS. EVENTUALLY WE TOOK OFF FROM RWY 31R. MADE THE L TURN DIRECT CRI INSIDE THE CRI 039 DEG RADIAL. I WAS HAND FLYING WITH THE MODE CTL PANEL IN LNAV MODE. I FOLLOWED THE FLT DIRECTOR AND OVER OR JUST PAST CRI DEP CTL TOLD US TO TURN L AND INTERCEPT THE CRI 223 DEG RADIAL. HE GAVE US A HDG OF 190 DEGS. SOMEHOW OR SOMEWHERE ALONG THE LINE THE CRI 223 DEG RADIAL AND RTE DISCONTINUITY WAS REMOVED/DROPPED OUT OF THE FMC AND WE WERE GOING DIRECT FROM CRI TO RBV; ABOUT A 240-245 DEG HDG. WE CORRECTED L TO 190 DEGS AS PER ATC INSTRUCTIONS; MANUALLY INTERCEPTED THE CRI 223 DEG RADIAL AND SHORTLY THEREAFTER WERE GIVEN DIRECT RBV. I BELIEVE WE OVERFLEW THE CRI 223 DEG RADIAL BY 1/2 TO 1 MI BEFORE TURNING BACK TO 190 DEGS TO REINTERCEPT THE CRI 223 DEG RADIAL. I TRULY DO NOT KNOW IF THIS WAS CAUSED BY FAULTY FMC LOADING OR A WRONG BUTTON PUSH EITHER BEFORE PUSHBACK OR ON TAXI-OUT WITH NUMEROUS DISTRS; OR A WRONG BUTTON PUSH ON DEP; OR AN FMS/FMC ANOMALY. NEXT TIME AND IN ALL FUTURE DEPS I WILL DOUBLE AND TRIPLE CHK FMC LOADING AND BACKUP RADIALS MANUALLY.
