Narrative:

Arrival route from northeast to iad is on V143 robrt intersection direct aml. R4009, when active, is hot to 12500 ft (over camp david), which is only 1/2 mi northwest of airway. Aircraft are routinely given 'depart robrt heading....' in this case, aircraft were given depart robrt heading 220 degrees radar vectors ILS approach runway 12. Due to tropical storm, northeast wind, were continuously violating R4009 requiring constant vigilance by north arrival controller. Air carrier flight drifted well into R4009, but was well within the 4 mi buffer for V143. An immediate heading of 180 degrees was issued, but not in time to avoid R4009. Patuxent NAS called to inquire and pilot deviation was going to be investigated. Solution: move V143 5 mi south. Supplemental information from acn 448117: flying the arrival on V143 into dulles. Cleared robrt 10000 ft, 250 KTS and once at robrt turn to heading 220 degrees. According to aircraft navaids we were centered on the radial and started the turn to assigned heading. Upon rolling out on a 180 degree heading, flight was then reclred right turn 220 degree heading. Upon landing, ground control told flight to contact TRACON on a landline. Mr X was contacted on the ground. Arriving aircraft into dulles from the north could be vectored down to kemar to stay away from R4009.

Title: A B727 FLT DRIFTS N OF AIRWAY V143 AND ENTERS R4009 PASSING ROBRT INTXN N OF IAD, DC.

Narrative: ARR RTE FROM NE TO IAD IS ON V143 ROBRT INTXN DIRECT AML. R4009, WHEN ACTIVE, IS HOT TO 12500 FT (OVER CAMP DAVID), WHICH IS ONLY 1/2 MI NW OF AIRWAY. ACFT ARE ROUTINELY GIVEN 'DEPART ROBRT HDG....' IN THIS CASE, ACFT WERE GIVEN DEPART ROBRT HDG 220 DEGS RADAR VECTORS ILS APCH RWY 12. DUE TO TROPICAL STORM, NE WIND, WERE CONTINUOUSLY VIOLATING R4009 REQUIRING CONSTANT VIGILANCE BY N ARR CTLR. ACR FLT DRIFTED WELL INTO R4009, BUT WAS WELL WITHIN THE 4 MI BUFFER FOR V143. AN IMMEDIATE HDG OF 180 DEGS WAS ISSUED, BUT NOT IN TIME TO AVOID R4009. PATUXENT NAS CALLED TO INQUIRE AND PLTDEV WAS GOING TO BE INVESTIGATED. SOLUTION: MOVE V143 5 MI S. SUPPLEMENTAL INFO FROM ACN 448117: FLYING THE ARR ON V143 INTO DULLES. CLRED ROBRT 10000 FT, 250 KTS AND ONCE AT ROBRT TURN TO HDG 220 DEGS. ACCORDING TO ACFT NAVAIDS WE WERE CTRED ON THE RADIAL AND STARTED THE TURN TO ASSIGNED HDG. UPON ROLLING OUT ON A 180 DEG HDG, FLT WAS THEN RECLRED R TURN 220 DEG HDG. UPON LNDG, GND CTL TOLD FLT TO CONTACT TRACON ON A LANDLINE. MR X WAS CONTACTED ON THE GND. ARRIVING ACFT INTO DULLES FROM THE N COULD BE VECTORED DOWN TO KEMAR TO STAY AWAY FROM R4009.
