Narrative:

Approaching rock springs, wy, sweet water county airport, from wsw, in a non radio equipped conventional gear aircraft, I determined the wind to be blowing from the west by observing some dust as I was flying past the city of rock springs. I did not observe any air traffic as I approached the traffic pattern. I entered the pattern on a 45 degree entry to downwind for runway 27. While on downwind I continued to scan for traffic and tried to find the wind direction indicators on the airport and was unable to find any. I continued my approach, abeam the runway 27 threshold and then turning base and final. I did not observe any air traffic as I cleared the area before making these pattern legs. I executed a normal wheel landing. After slowing the aircraft, lowering the tail and slowing to a fast taxi speed, I proceeded to the next available taxiway. I had been on the ground approximately 30 seconds when an small transport flew by me a little off of my right wing at about 50' AGL. I exited the runway by the taxiway, and continued on the tie down area. The small transport did not return for landing. I was on the airfield for the next 45 mins and the small transport did not return while I was there. I talked with two other pilots and one nonplt that had observed my approach to the traffic pattern, continued approach and landing. They had been waiting for my arrival and had been in a position to observe the traffic pattern for some time. They stated they did not observe the small transport until after I had landed and the small transport was then on short final. They had not observed the small transport before seeing it on short final. Some of the contributing factors to this incident are as follows: the wind direction indicators were practically invisible due to there faded condition and color of the ground around them. I talked with another non radio pilot who stated that he had made two circuits around the airfield and was still unable to locate the wind direction indicators. Wind direction indicators should be maintained in a bright color condition and a contrasting backgnd would greatly help their visibility from aircraft in flight. Callback conversation with reporter revealed the following information. Reporter was delivering an aerial applicator aircraft to new owner. Unknown if second aircraft was planning to land or making a practice instrument approach. Did not return to airport although this was home base.

Title: POOR WINDS INDICATORS AT UNCONTROLLED FIELD AND CONFLICT BETWEEN SMA TAXIING OFF RWY AND SMT ON APCH TO LAND.

Narrative: APCHING ROCK SPRINGS, WY, SWEET WATER COUNTY ARPT, FROM WSW, IN A NON RADIO EQUIPPED CONVENTIONAL GEAR ACFT, I DETERMINED THE WIND TO BE BLOWING FROM THE W BY OBSERVING SOME DUST AS I WAS FLYING PAST THE CITY OF ROCK SPRINGS. I DID NOT OBSERVE ANY AIR TFC AS I APCHED THE TFC PATTERN. I ENTERED THE PATTERN ON A 45 DEG ENTRY TO DOWNWIND FOR RWY 27. WHILE ON DOWNWIND I CONTINUED TO SCAN FOR TFC AND TRIED TO FIND THE WIND DIRECTION INDICATORS ON THE ARPT AND WAS UNABLE TO FIND ANY. I CONTINUED MY APCH, ABEAM THE RWY 27 THRESHOLD AND THEN TURNING BASE AND FINAL. I DID NOT OBSERVE ANY AIR TFC AS I CLRED THE AREA BEFORE MAKING THESE PATTERN LEGS. I EXECUTED A NORMAL WHEEL LNDG. AFTER SLOWING THE ACFT, LOWERING THE TAIL AND SLOWING TO A FAST TAXI SPD, I PROCEEDED TO THE NEXT AVAILABLE TXWY. I HAD BEEN ON THE GND APPROX 30 SECS WHEN AN SMT FLEW BY ME A LITTLE OFF OF MY R WING AT ABOUT 50' AGL. I EXITED THE RWY BY THE TXWY, AND CONTINUED ON THE TIE DOWN AREA. THE SMT DID NOT RETURN FOR LNDG. I WAS ON THE AIRFIELD FOR THE NEXT 45 MINS AND THE SMT DID NOT RETURN WHILE I WAS THERE. I TALKED WITH TWO OTHER PLTS AND ONE NONPLT THAT HAD OBSERVED MY APCH TO THE TFC PATTERN, CONTINUED APCH AND LNDG. THEY HAD BEEN WAITING FOR MY ARR AND HAD BEEN IN A POS TO OBSERVE THE TFC PATTERN FOR SOME TIME. THEY STATED THEY DID NOT OBSERVE THE SMT UNTIL AFTER I HAD LANDED AND THE SMT WAS THEN ON SHORT FINAL. THEY HAD NOT OBSERVED THE SMT BEFORE SEEING IT ON SHORT FINAL. SOME OF THE CONTRIBUTING FACTORS TO THIS INCIDENT ARE AS FOLLOWS: THE WIND DIRECTION INDICATORS WERE PRACTICALLY INVISIBLE DUE TO THERE FADED CONDITION AND COLOR OF THE GND AROUND THEM. I TALKED WITH ANOTHER NON RADIO PLT WHO STATED THAT HE HAD MADE TWO CIRCUITS AROUND THE AIRFIELD AND WAS STILL UNABLE TO LOCATE THE WIND DIRECTION INDICATORS. WIND DIRECTION INDICATORS SHOULD BE MAINTAINED IN A BRIGHT COLOR CONDITION AND A CONTRASTING BACKGND WOULD GREATLY HELP THEIR VISIBILITY FROM ACFT IN FLT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO. RPTR WAS DELIVERING AN AERIAL APPLICATOR ACFT TO NEW OWNER. UNKNOWN IF SECOND ACFT WAS PLANNING TO LAND OR MAKING A PRACTICE INSTRUMENT APCH. DID NOT RETURN TO ARPT ALTHOUGH THIS WAS HOME BASE.
