Narrative:
Air carrier X was being vectored for spacing to lga along with approximately 6 other aircraft in sector on vectors for spacing to lga. 20 mi intrail restrictions required leaving hpw high sector with no spacing required on aircraft entering sector. I was also working approximately 6 additional aircraft at time of incident. I requested an l-side (handoff) controller. My d-side moved to l-side and I instructed l-side to point out air carrier X to shd sector (aircraft on 340 heading nearing sector boundary when point out accomplished). Aircraft already within 2 NM of receiving controllers airspace. Aircraft then cleared on course without further incident. Factors that I believe contributed to this incident are lack of sufficient help from flow control (restrictions from 20 mi intrail (mit) to 10 mit after incident). I was not aware of volume of lga traffic approaching sector (supervisor advised by flow control that only 2 or 3 lga airplanes looked to be a problem). Not accepting d-sides advise to put some of traffic in holding to reduce vectoring required. Supplemental information from acn 188543. As the handoff controller, I pointed out air carrier X to the R72 controller as he was approaching the boundary. R72 approved the point out but stated it was a little late. There was traffic for air carrier X at the same altitude (an air carrier at FL350). As I pointed out air carrier X to R72, I stated 'we will miss the air carrier.'
Original NASA ASRS Text
Title: CTLR OVERLOADED WITH TFC, ALLOWS AN ACR TO ENTER ANOTHER CTLRS AIRSPACE WITH LATE HDOF.
Narrative: ACR X WAS BEING VECTORED FOR SPACING TO LGA ALONG WITH APPROX 6 OTHER ACFT IN SECTOR ON VECTORS FOR SPACING TO LGA. 20 MI INTRAIL RESTRICTIONS REQUIRED LEAVING HPW HIGH SECTOR WITH NO SPACING REQUIRED ON ACFT ENTERING SECTOR. I WAS ALSO WORKING APPROX 6 ADDITIONAL ACFT AT TIME OF INCIDENT. I REQUESTED AN L-SIDE (HDOF) CTLR. MY D-SIDE MOVED TO L-SIDE AND I INSTRUCTED L-SIDE TO POINT OUT ACR X TO SHD SECTOR (ACFT ON 340 HDG NEARING SECTOR BOUNDARY WHEN POINT OUT ACCOMPLISHED). ACFT ALREADY WITHIN 2 NM OF RECEIVING CTLRS AIRSPACE. ACFT THEN CLRED ON COURSE WITHOUT FURTHER INCIDENT. FACTORS THAT I BELIEVE CONTRIBUTED TO THIS INCIDENT ARE LACK OF SUFFICIENT HELP FROM FLOW CTL (RESTRICTIONS FROM 20 MI INTRAIL (MIT) TO 10 MIT AFTER INCIDENT). I WAS NOT AWARE OF VOLUME OF LGA TFC APCHING SECTOR (SUPVR ADVISED BY FLOW CTL THAT ONLY 2 OR 3 LGA AIRPLANES LOOKED TO BE A PROBLEM). NOT ACCEPTING D-SIDES ADVISE TO PUT SOME OF TFC IN HOLDING TO REDUCE VECTORING REQUIRED. SUPPLEMENTAL INFO FROM ACN 188543. AS THE HDOF CTLR, I POINTED OUT ACR X TO THE R72 CTLR AS HE WAS APCHING THE BOUNDARY. R72 APPROVED THE POINT OUT BUT STATED IT WAS A LITTLE LATE. THERE WAS TFC FOR ACR X AT THE SAME ALT (AN ACR AT FL350). AS I POINTED OUT ACR X TO R72, I STATED 'WE WILL MISS THE ACR.'
