Near midair collision. Reporter instructor pilot observed intruder aircraft just as it passed under his aircraft. Reporter was at appropriate VFR altitude, so the intruder must have not been at correct altitude. Reporter also says that he was down sun and should have been able to see his aircraft. High wing intruder and low wing reporter, resulting in a see and avoid problem.

Narrative:
Was conducting instrument training for instrument student of major foreign airline. Proceeding inbound on 055 degree radial (235 degree magnetic course) to standfield VOR (tfd). Had just completed level off approximately 50 ft above proper cruise altitude of 6500 ft MSL (VFR altitude for direction of flight). Observed a large high wing aircraft fly under my left wingtip heading in a northwest or north direction. Aircraft passed 50-100 ft under my aircraft from left to right, emerging from under my aircraft between the right wingtip and horizontal stabilizer. Upon emerging from under my aircraft I could plainly see that it was a cessna caravan (T208) belonging to air carrier as company markings were clearly visible. Visibility at time of incident was 30 mi plus, sun angle was approximately 10 degrees above horizon (35-40 mins prior to official sunset). Since I was 'down sun,' the other pilot should have been able to see my aircraft. This appears to be a classic high- wing/low-wing conflict, exacerbated by the fact that the respective pics are on opposite sides of the aircraft (as instructor, I was occupying right seat).

Title: NMAC. RPTR INSTRUCTOR PLT OBSERVED INTRUDER ACFT JUST AS IT PASSED UNDER HIS ACFT. RPTR WAS AT APPROPRIATE VFR ALT, SO THE INTRUDER MUST HAVE NOT BEEN AT CORRECT ALT. RPTR ALSO SAYS THAT HE WAS DOWN SUN AND SHOULD HAVE BEEN ABLE TO SEE HIS ACFT. HIGH WING INTRUDER AND LOW WING RPTR, RESULTING IN A SEE AND AVOID PROB.
Narrative: WAS CONDUCTING INST TRAINING FOR INST STUDENT OF MAJOR FOREIGN AIRLINE. PROCEEDING INBOUND ON 055 DEG RADIAL (235 DEG MAGNETIC COURSE) TO STANDFIELD VOR (TFD). HAD JUST COMPLETED LEVEL OFF APPROX 50 FT ABOVE PROPER CRUISE ALT OF 6500 FT MSL (VFR ALT FOR DIRECTION OF FLT). OBSERVED A LARGE HIGH WING ACFT FLY UNDER MY L WINGTIP HEADING IN A NW OR N DIRECTION. ACFT PASSED 50-100 FT UNDER MY ACFT FROM L TO R, EMERGING FROM UNDER MY ACFT BTWN THE R WINGTIP AND HORIZ STABILIZER. UPON EMERGING FROM UNDER MY ACFT I COULD PLAINLY SEE THAT IT WAS A CESSNA CARAVAN (T208) BELONGING TO ACR AS COMPANY MARKINGS WERE CLRLY VISIBLE. VISIBILITY AT TIME OF INCIDENT WAS 30 MI PLUS, SUN ANGLE WAS APPROX 10 DEGS ABOVE HORIZON (35-40 MINS PRIOR TO OFFICIAL SUNSET). SINCE I WAS 'DOWN SUN,' THE OTHER PLT SHOULD HAVE BEEN ABLE TO SEE MY ACFT. THIS APPEARS TO BE A CLASSIC HIGH- WING/LOW-WING CONFLICT, EXACERBATED BY THE FACT THAT THE RESPECTIVE PICS ARE ON OPPOSITE SIDES OF THE ACFT (AS INSTRUCTOR, I WAS OCCUPYING R SEAT).
