Narrative:
We had departed roc and picked up a squawk code from binghamton which was passed to ZNY and then to ZBW, then back to ZNY. Before landing we flew V34 direct to hnk, then LORAN direct to dxr. This put us on V167. Very close to helon intersection we had a close head on encounter. Evasive action was taken by both aircraft while under ZBW radar. The other aircraft was IFR in VFR conditions. I asked center what stewart's altimeter was and checked that mine was set properly. It was and I was within 75' of my altitude of 7500' MSL. The other pilot immediately stated I was not at 7500', but closer to his assigned altitude of 7000'. He then called center twice, questioning why center had not called the traffic. Finally center stated he was sorry for not doing it. The other pilot (type and north number unknown) was more verbal and upset on the radio. Center was not real busy at this time, in my opinion. I slept on this overnight and then called an ATP pilot and my local tower controllers. Fri was a holiday and the number for ZBW I had was not answering. On 11/mon/88 I called ZBW to ask to talk to the controller on duty. They said they would call me back and seemed very concerned. I then filed this form. I felt this was the fault of no action taken on the part of the controller in ZBW and wondered why.

Title: GA SMA HAD CLOSE ENCOUNTER WITH UNKNOWN ACFT THAT WAS IFR AT 7000'.
Narrative: WE HAD DEPARTED ROC AND PICKED UP A SQUAWK CODE FROM BINGHAMTON WHICH WAS PASSED TO ZNY AND THEN TO ZBW, THEN BACK TO ZNY. BEFORE LNDG WE FLEW V34 DIRECT TO HNK, THEN LORAN DIRECT TO DXR. THIS PUT US ON V167. VERY CLOSE TO HELON INTXN WE HAD A CLOSE HEAD ON ENCOUNTER. EVASIVE ACTION WAS TAKEN BY BOTH ACFT WHILE UNDER ZBW RADAR. THE OTHER ACFT WAS IFR IN VFR CONDITIONS. I ASKED CENTER WHAT STEWART'S ALTIMETER WAS AND CHKED THAT MINE WAS SET PROPERLY. IT WAS AND I WAS WITHIN 75' OF MY ALT OF 7500' MSL. THE OTHER PLT IMMEDIATELY STATED I WAS NOT AT 7500', BUT CLOSER TO HIS ASSIGNED ALT OF 7000'. HE THEN CALLED CENTER TWICE, QUESTIONING WHY CENTER HAD NOT CALLED THE TFC. FINALLY CENTER STATED HE WAS SORRY FOR NOT DOING IT. THE OTHER PLT (TYPE AND N NUMBER UNKNOWN) WAS MORE VERBAL AND UPSET ON THE RADIO. CENTER WAS NOT REAL BUSY AT THIS TIME, IN MY OPINION. I SLEPT ON THIS OVERNIGHT AND THEN CALLED AN ATP PLT AND MY LCL TWR CTLRS. FRI WAS A HOLIDAY AND THE NUMBER FOR ZBW I HAD WAS NOT ANSWERING. ON 11/MON/88 I CALLED ZBW TO ASK TO TALK TO THE CTLR ON DUTY. THEY SAID THEY WOULD CALL ME BACK AND SEEMED VERY CONCERNED. I THEN FILED THIS FORM. I FELT THIS WAS THE FAULT OF NO ACTION TAKEN ON THE PART OF THE CTLR IN ZBW AND WONDERED WHY.
