Narrative:
ATC told us to intercept V143 (mrb 065 degree radial). After a while, showing needle centered, ATC verified we were to intercept V143 and told us we were off course and to re- intercept on a 280 degree heading. I told him we were showing centerline and asked how far off he showed us. He stated 4 mi, increasing. I then asked for vectors to remain on airway. The captain decided not to write up the navs (they were within dual VOR test limits). At worst case, our vors showed only 1 1/2 - 2 mi off course.

Narrative: ATC TOLD US TO INTERCEPT V143 (MRB 065 DEG RADIAL). AFTER A WHILE, SHOWING NEEDLE CTRED, ATC VERIFIED WE WERE TO INTERCEPT V143 AND TOLD US WE WERE OFF COURSE AND TO RE- INTERCEPT ON A 280 DEG HDG. I TOLD HIM WE WERE SHOWING CTRLINE AND ASKED HOW FAR OFF HE SHOWED US. HE STATED 4 MI, INCREASING. I THEN ASKED FOR VECTORS TO REMAIN ON AIRWAY. THE CAPT DECIDED NOT TO WRITE UP THE NAVS (THEY WERE WITHIN DUAL VOR TEST LIMITS). AT WORST CASE, OUR VORS SHOWED ONLY 1 1/2 - 2 MI OFF COURSE.
