Narrative:

Air carrier X was approaching dca. The mt vernon visibility approach was in use. Approximately 12 mi southeast of the dca VOR dca approach cleared us to fly a 320 degree heading and maintain 2500'. We flew through the final approach on this heading. When our aircraft was approximately 1 1/2 mi west of the final approach course the controller asked us if we were turning to 'intercept the river.' I replied that we were flying a 320 degree heading. The controller then issued us a right turn to intercept the final approach course and an approach clearance. The controller initially did not issue us a clearance to intercept the final approach, however from the tone of his voice I could tell that he thought he did. This controller was too busy to properly issue instructions, and too busy to monitor our flight on radar. Unfortunately this type of controller workload is far too common.

Title: ACR X FLT CREW FAILED TO COMPLY WITH ACT CLRNC. PLT DEVIATION.

Narrative: ACR X WAS APCHING DCA. THE MT VERNON VIS APCH WAS IN USE. APPROX 12 MI SE OF THE DCA VOR DCA APCH CLRED US TO FLY A 320 DEG HDG AND MAINTAIN 2500'. WE FLEW THROUGH THE FINAL APCH ON THIS HDG. WHEN OUR ACFT WAS APPROX 1 1/2 MI W OF THE FINAL APCH COURSE THE CTLR ASKED US IF WE WERE TURNING TO 'INTERCEPT THE RIVER.' I REPLIED THAT WE WERE FLYING A 320 DEG HDG. THE CTLR THEN ISSUED US A RIGHT TURN TO INTERCEPT THE FINAL APCH COURSE AND AN APCH CLRNC. THE CTLR INITIALLY DID NOT ISSUE US A CLRNC TO INTERCEPT THE FINAL APCH, HOWEVER FROM THE TONE OF HIS VOICE I COULD TELL THAT HE THOUGHT HE DID. THIS CTLR WAS TOO BUSY TO PROPERLY ISSUE INSTRUCTIONS, AND TOO BUSY TO MONITOR OUR FLT ON RADAR. UNFORTUNATELY THIS TYPE OF CTLR WORKLOAD IS FAR TOO COMMON.
