Narrative:

This occurred on nov/tue/93, during a part 135 sic chkride in nx, an small transport. I was the check airman, in the left seat. The flight was on an IFR flight plan with IFR separation. We were returning to mke from osh to do 2 ILS approachs at mke, with the sic in the right seat, under the hood. We began our first ILS at approximately XA05 hours local time. Mke ATIS was 1100 scattered 1400 broken 4100 overcast, 4 mi visibility in light rain and fog, temperature and dewpoint were 42/42, wind 2007. The ILS 19R was in use. The sun had set and the clouds made it fully dark. During the final approach, when we were approximately 1000 ft AGL, tower reported 'small aircraft, traffic at about 1 O'clock (and several mi),' that would be overflying the airport for runway 19L. We were IMC at about 1700 ft MSL, with frequent ground contact through lower scud. All external lights were on. Shortly after that, tower reported the small aircraft as 800 ft above us, at our 1 O'clock position, 1 1/2 mi. The sic was under the hood and I could see the VASI and runway lights, but forward visibility was low due to precipitation, fog and scud. I saw no traffic due to the reduced visibility, and observed ragged clouds above, below and all around us. The controller next called traffic at 12 O'clock, less than a mi, 300 ft above us. I still saw nothing due to clouds. The controller immediately instructed us to execute the missed approach. The missed approach instructions, issued earlier by the tower were: '210 degrees, 3000 ft,' a turn that would take us toward the position of the reported traffic, and climb us through its altitude. I still saw no traffic and the WX had not improved. We were still in clouds and precipitation, though with better ground contact, and runway lights in sight before approximately 500 ft AGL (somewhere between 1100 ft and 1300 ft MSL). At about this time the controller stated that the small aircraft was directly above us. The sic began the missed approach with a climbing right turn. As he reached 20 degrees of bank I looked up, off our left wingtip, and saw a light, possibly a landing light, at 9 O'clock, above us. I cannot estimate the distance or altitude due to the clouds and the parallax on a single point of fuzzy light. It was in thicker clouds than we were. My recollection of timing, our altitude and position may not be precise, but we were well south of the lake michigan shore, on the GS and localizer, almost over the approach lights when the sic began the turn. I do remember descending through 1300 ft MSL. I telephoned the tower supervisor at about XB15 hours. He contacted the tower controller who was working during our approach. The controller said the small aircraft was a traffic watch plane, and that he (the controller) had the small aircraft and us in sight and was maintaining visual separation for us. He also said that the small aircraft pilot reported us in sight and stated to the controller that he was 'clear of clouds.' the tower supervisor said the controller had noted the actual field conditions and wondered at the small aircraft pilot's statement about being VFR. During our missed approach, we were given additional vectors of 260 degrees and then 300 degrees (approximately, I don't remember the precise headings). As we turned into the area through which the small aircraft pilot had flown, I estimate that although we had frequent ground contact through the scud and mixed snow and rain, we were not VFR at any time during our climb to 3000 ft. Ground contact diminished as we climbed and was lost before we were level. I also lost sight of the light, which was probably the small aircraft before passing through its altitude.

Title: NMAC BTWN AN ATX JET ON A TRAINING FLT ILS AND AN SMA SEL TFC WATCH ACFT XING OVER THE FINAL APCH.

Narrative: THIS OCCURRED ON NOV/TUE/93, DURING A PART 135 SIC CHKRIDE IN NX, AN SMT. I WAS THE CHK AIRMAN, IN THE L SEAT. THE FLT WAS ON AN IFR FLT PLAN WITH IFR SEPARATION. WE WERE RETURNING TO MKE FROM OSH TO DO 2 ILS APCHS AT MKE, WITH THE SIC IN THE R SEAT, UNDER THE HOOD. WE BEGAN OUR FIRST ILS AT APPROX XA05 HRS LCL TIME. MKE ATIS WAS 1100 SCATTERED 1400 BROKEN 4100 OVCST, 4 MI VISIBILITY IN LIGHT RAIN AND FOG, TEMP AND DEWPOINT WERE 42/42, WIND 2007. THE ILS 19R WAS IN USE. THE SUN HAD SET AND THE CLOUDS MADE IT FULLY DARK. DURING THE FINAL APCH, WHEN WE WERE APPROX 1000 FT AGL, TWR RPTED 'SMA, TFC AT ABOUT 1 O'CLOCK (AND SEVERAL MI),' THAT WOULD BE OVERFLYING THE ARPT FOR RWY 19L. WE WERE IMC AT ABOUT 1700 FT MSL, WITH FREQUENT GND CONTACT THROUGH LOWER SCUD. ALL EXTERNAL LIGHTS WERE ON. SHORTLY AFTER THAT, TWR RPTED THE SMA AS 800 FT ABOVE US, AT OUR 1 O'CLOCK POS, 1 1/2 MI. THE SIC WAS UNDER THE HOOD AND I COULD SEE THE VASI AND RWY LIGHTS, BUT FORWARD VISIBILITY WAS LOW DUE TO PRECIPITATION, FOG AND SCUD. I SAW NO TFC DUE TO THE REDUCED VISIBILITY, AND OBSERVED RAGGED CLOUDS ABOVE, BELOW AND ALL AROUND US. THE CTLR NEXT CALLED TFC AT 12 O'CLOCK, LESS THAN A MI, 300 FT ABOVE US. I STILL SAW NOTHING DUE TO CLOUDS. THE CTLR IMMEDIATELY INSTRUCTED US TO EXECUTE THE MISSED APCH. THE MISSED APCH INSTRUCTIONS, ISSUED EARLIER BY THE TWR WERE: '210 DEGS, 3000 FT,' A TURN THAT WOULD TAKE US TOWARD THE POS OF THE RPTED TFC, AND CLB US THROUGH ITS ALT. I STILL SAW NO TFC AND THE WX HAD NOT IMPROVED. WE WERE STILL IN CLOUDS AND PRECIPITATION, THOUGH WITH BETTER GND CONTACT, AND RWY LIGHTS IN SIGHT BEFORE APPROX 500 FT AGL (SOMEWHERE BTWN 1100 FT AND 1300 FT MSL). AT ABOUT THIS TIME THE CTLR STATED THAT THE SMA WAS DIRECTLY ABOVE US. THE SIC BEGAN THE MISSED APCH WITH A CLBING R TURN. AS HE REACHED 20 DEGS OF BANK I LOOKED UP, OFF OUR L WINGTIP, AND SAW A LIGHT, POSSIBLY A LNDG LIGHT, AT 9 O'CLOCK, ABOVE US. I CANNOT ESTIMATE THE DISTANCE OR ALT DUE TO THE CLOUDS AND THE PARALLAX ON A SINGLE POINT OF FUZZY LIGHT. IT WAS IN THICKER CLOUDS THAN WE WERE. MY RECOLLECTION OF TIMING, OUR ALT AND POS MAY NOT BE PRECISE, BUT WE WERE WELL S OF THE LAKE MICHIGAN SHORE, ON THE GS AND LOC, ALMOST OVER THE APCH LIGHTS WHEN THE SIC BEGAN THE TURN. I DO REMEMBER DSNDING THROUGH 1300 FT MSL. I TELEPHONED THE TWR SUPVR AT ABOUT XB15 HRS. HE CONTACTED THE TWR CTLR WHO WAS WORKING DURING OUR APCH. THE CTLR SAID THE SMA WAS A TFC WATCH PLANE, AND THAT HE (THE CTLR) HAD THE SMA AND US IN SIGHT AND WAS MAINTAINING VISUAL SEPARATION FOR US. HE ALSO SAID THAT THE SMA PLT RPTED US IN SIGHT AND STATED TO THE CTLR THAT HE WAS 'CLR OF CLOUDS.' THE TWR SUPVR SAID THE CTLR HAD NOTED THE ACTUAL FIELD CONDITIONS AND WONDERED AT THE SMA PLT'S STATEMENT ABOUT BEING VFR. DURING OUR MISSED APCH, WE WERE GIVEN ADDITIONAL VECTORS OF 260 DEGS AND THEN 300 DEGS (APPROX, I DON'T REMEMBER THE PRECISE HDGS). AS WE TURNED INTO THE AREA THROUGH WHICH THE SMA PLT HAD FLOWN, I ESTIMATE THAT ALTHOUGH WE HAD FREQUENT GND CONTACT THROUGH THE SCUD AND MIXED SNOW AND RAIN, WE WERE NOT VFR AT ANY TIME DURING OUR CLB TO 3000 FT. GND CONTACT DIMINISHED AS WE CLBED AND WAS LOST BEFORE WE WERE LEVEL. I ALSO LOST SIGHT OF THE LIGHT, WHICH WAS PROBABLY THE SMA BEFORE PASSING THROUGH ITS ALT.
