Narrative:

I was flying right seat as safety pilot. We were talking to ZSE and monitoring salem tower. As I recall, center gave us traffic at our 5 O'clock position at 1600 ft, east to west. At this time we were at 2000 ft and descending on the localizer, inbound. Center's next transmission was that the other aircraft was directly under us. Our aircraft, being a low wing, made it difficult to locate the other aircraft. The PIC canceled IFR and made a climbing r-hand turn (a 360 degree turn) and upon completing this turn was able to locate the #2 aircraft just prior to touchdown. We had contact with sle tower by this time and were #2 to land on runway 31. We requested a low approach and proceeded to independence state airport (7s5). Supplemental information from acn 448583: center cleared me to climb to 4000 ft. I canceled IFR, made a climbing right turn back to the localizer course and made a low approach behind the other aircraft which had landed.

Original NASA ASRS Text

Title: 2 WELL EXPERIENCED PVT PLTS, FLYING IFR ON THE ILS TO SLE, WERE WARNED OF AN ACFT DIRECTLY UNDERNEATH THEM. THE PF WAS UNDER THE HOOD AND COULD NOT SEE WELL ENOUGH OUTSIDE AND THE SAFETY PLT WAS UNABLE TO ESTABLISH CONTACT AS THIS WAS A LOW WING ACFT. CTR ALLOWED THE PLT TO TAKE EVASIVE ACTION BY CLBING TO A NEW ALT.

Narrative: I WAS FLYING R SEAT AS SAFETY PLT. WE WERE TALKING TO ZSE AND MONITORING SALEM TWR. AS I RECALL, CTR GAVE US TFC AT OUR 5 O'CLOCK POS AT 1600 FT, E TO W. AT THIS TIME WE WERE AT 2000 FT AND DSNDING ON THE LOC, INBOUND. CTR'S NEXT XMISSION WAS THAT THE OTHER ACFT WAS DIRECTLY UNDER US. OUR ACFT, BEING A LOW WING, MADE IT DIFFICULT TO LOCATE THE OTHER ACFT. THE PIC CANCELED IFR AND MADE A CLBING R-HAND TURN (A 360 DEG TURN) AND UPON COMPLETING THIS TURN WAS ABLE TO LOCATE THE #2 ACFT JUST PRIOR TO TOUCHDOWN. WE HAD CONTACT WITH SLE TWR BY THIS TIME AND WERE #2 TO LAND ON RWY 31. WE REQUESTED A LOW APCH AND PROCEEDED TO INDEPENDENCE STATE ARPT (7S5). SUPPLEMENTAL INFO FROM ACN 448583: CTR CLRED ME TO CLB TO 4000 FT. I CANCELED IFR, MADE A CLBING R TURN BACK TO THE LOC COURSE AND MADE A LOW APCH BEHIND THE OTHER ACFT WHICH HAD LANDED.
