Narrative:

Controller: 'baron, you have traffic 1 O'clock, 2 mi, approximately 5000 ft.' jetstream: 'at 7000 ft, I am looking and see the landing lights and report traffic in sight.' 'not so' the jetstream pilot, 'I am at 6000 ft' and controller instructs 'maintain visual to the jetstream and climb and maintain 7000 ft.' I hear the controller talking to the jetstream pilot saying something like, 'the baron has you in sight and maintains visual. He will climb through your altitude, descend and maintain 3000 ft.' I saw him still far away and thought that I better hurry up to 7000 ft. My climb was very quick and as I leveled off, the jetstream came very quick closer. Because of the quick climb, my performance was reduced so that I had only the option for a dive. When I got the airplane's nose down, the jetstream passed just ahead and above. The distance at night is hard to judge, but we missed maybe by 100 ft horizontal and vertical. After passing and leveloff, again I checked my takeoff notes to find out what went wrong. I discovered that the altimeter on the ATIS in ric was 29.74 and I misread it and had 29.94. When I leveled off at 7000 ft, I leveled actually at 6800 ft and caught the jetstream in its descent.

Title: BE58 WITH WRONG ALTIMETER SETTING ADDS TO HAZARDOUS NATURE OF NMAC AT RIC.

Narrative: CTLR: 'BARON, YOU HAVE TFC 1 O'CLOCK, 2 MI, APPROX 5000 FT.' JETSTREAM: 'AT 7000 FT, I AM LOOKING AND SEE THE LNDG LIGHTS AND RPT TFC IN SIGHT.' 'NOT SO' THE JETSTREAM PLT, 'I AM AT 6000 FT' AND CTLR INSTRUCTS 'MAINTAIN VISUAL TO THE JETSTREAM AND CLB AND MAINTAIN 7000 FT.' I HEAR THE CTLR TALKING TO THE JETSTREAM PLT SAYING SOMETHING LIKE, 'THE BARON HAS YOU IN SIGHT AND MAINTAINS VISUAL. HE WILL CLB THROUGH YOUR ALT, DSND AND MAINTAIN 3000 FT.' I SAW HIM STILL FAR AWAY AND THOUGHT THAT I BETTER HURRY UP TO 7000 FT. MY CLB WAS VERY QUICK AND AS I LEVELED OFF, THE JETSTREAM CAME VERY QUICK CLOSER. BECAUSE OF THE QUICK CLB, MY PERFORMANCE WAS REDUCED SO THAT I HAD ONLY THE OPTION FOR A DIVE. WHEN I GOT THE AIRPLANE'S NOSE DOWN, THE JETSTREAM PASSED JUST AHEAD AND ABOVE. THE DISTANCE AT NIGHT IS HARD TO JUDGE, BUT WE MISSED MAYBE BY 100 FT HORIZ AND VERT. AFTER PASSING AND LEVELOFF, AGAIN I CHKED MY TKOF NOTES TO FIND OUT WHAT WENT WRONG. I DISCOVERED THAT THE ALTIMETER ON THE ATIS IN RIC WAS 29.74 AND I MISREAD IT AND HAD 29.94. WHEN I LEVELED OFF AT 7000 FT, I LEVELED ACTUALLY AT 6800 FT AND CAUGHT THE JETSTREAM IN ITS DSCNT.
