IFR PA31 WITH PCT TRACON WAS ISSUED AN INCORRECT ATC FREQ ASSIGNMENT THAT RESULTED IN AN AIRSPACE INCURSION WITH R-6611.

Narrative

ON AN IFR FLT; JST TO 2W6 (ST MARY'S; MD) WE EXPERIENCED AN ATC HANDLING/COM SIT. WE WERE VECTORED AROUND THE WASHINGTON ADIZ. OUR LAST ASSIGNED INSTRUCTIONS WERE DIRECT 2W6; DSND AND MAINTAIN 5000 FT (FROM 7000 FT) AND CONTACT POTOMAC ON 118.65; WHICH WE COMPLIED WITH. POTOMAC APCH WAS EXTREMELY BUSY. INITIAL CALL-UP WE WERE IGNORED; NO RESPONSE! I FIGURED OK; WELL HE IS BUSY; HE'LL GET BACK TO US. HE NEVER DID. ON OUR GPS WE COULD SEE R-6611 WAS GOING TO BE IN OUR RTE. MY COPLT CALLED TO QUESTION THE STATUS OF R-6611. WE WERE AGAIN IGNORED. I TRIED AGAIN; IGNORED. WE KEPT PROCEEDING EBOUND AND PENETRATED R-6611. STILL NO RESPONSE FROM POTOMAC APCH. I CALLED PATUXENT ON 120.05 AND EXPLAINED; COULD THEY HELP US OUT. YES. WE WERE 6 NM FROM 2W6 AT 5000 FT. SHE CLRED US FOR THE VISUAL APCH. OUT OF 3000 FT MSL OVER THE ARPT; WE CANCELED THE IFR AND LANDED AT 2W6. UPON EXITING THE ACFT; THE LINE MAN GAVE ME A NOTE TO CALL PATUXENT. I DID. THEY SAID 'POTOMAC WANTS TO TALK TO YOU.' I SPOKE WITH A MR X. HE QUESTIONED ME ON WHAT I JUST EXPLAINED. HE SAID THEY HAVE NO STRIP ON ME. WHAT? I'M IFR SQUAWKING XXXX! YES I'M IFR! 'WHEN POTOMAC DID NOT REPLY; YOU (ME) SHOULD HAVE GONE BACK TO THE LAST ASSIGNED FREQ. THIS IS NOT ABOUT GOING INTO R-6611 IT IS ABOUT NOT TALKING TO ANYONE. WE (POTOMAC) WERE WATCHING YOU.' NOW I'M THINKING WHAT ABOUT TFC CONFLICTS? WHAT IF WE HAD A NEAR MISS? MR X TOLD ME WE SHOULD HAVE BEEN ASSIGNED A SLOW SECTOR BUT WE WERE SENT TO A BUSY ONE BY MISTAKE. THEY HAD A TRAINEE WORKING WITH A SUPVR. HE THEN SAID HE CAN SEE WHAT HAPPENED. THIS IS AN UNRECORDED PHONE LINE AND THE SECRET SVC WILL NOT BE NOTIFIED. HE THEN SAID IT APPEARS TO BE ATC PROB; NOT MINE. DO NOT WORRY ABOUT IT.
