PLT OF PA28 FEARS HE INADVERTENTLY CAUSED A CONFLICT ON LNDG AT UNCTLED LVJ DUE TO XMITTING POS ADVISORIES ON THE WRONG CTAF FREQ.

Narrative

I BELIEVE I MAY HAVE PARTICIPATED IN A NEAR MIDAIR OR NEAR GND COLLISION; BASED ON HOW EVENTS HAVE BEEN DESCRIBED TO ME. I WAS RETURNING TO LVJ; LOCATED IN THE SOUTHERN PORTION OF THE HOUSTON TERMINAL AIRSPACE MODE C VEIL. I WAS RETURNING FROM THE NORTHERN PART OF ZFW'S AIRSPACE. I MADE MY TRIP UNDER VFR; WITHOUT FLT PLAN; BUT WITH CONTINUOUS FLT FOLLOWING FROM THE APPROPRIATE CTRS AND APCH CTLS; WITH MY LAST FLT FOLLOWING CONTACT BEING WITH HOU APCH. I DO NOT FEEL APCH WAS A CONTRIBUTING FACTOR. ON ARR INTO THE HOUSTON TERMINAL AIRSPACE; I WAS VECTORED WITHIN THE WESTERN PORTION OF THE CLASS B AIRSPACE; GIVEN STEPWISE DSCNTS AND EVENTUALLY WAS RELEASED/TERMINATED FROM RADAR SVC APCHING FROM THE NW INTO LVJ; UNDERNEATH THE CLASS B AIRSPACE IN THAT AREA. I OBTAINED AUTOMATED WX ON CLOVER'S DESIGNATED FREQ AND NOTED THAT WINDS WERE CALM ON SEVERAL OCCASIONS. WHEN I WAS TERMINATED FROM FLT FOLLOWING I WAS TOLD THERE WAS ONE UNVERIFIED TARGET THAT APPEARED IN THE PATTERN AT CLOVER AND I BEGAN TO LOOK ACCORDINGLY. AS I APCHED THE FIELD; I SWITCHED TO ADVISORY AND ANNOUNCED MY APCH FROM THE W; FULL STOP LNDG AT CLOVER. I HEARD 1 ACFT CALLING TFC PATTERN POS FOR RWY 22; AND I LOOKED CAREFULLY FOR THIS TFC. I DID NOT SEE THE ACFT; BUT NOTED MENTALLY THAT RWY 4/22 IS A SHORT UNPAVED RWY (2400 FT APPROX) THAT IS NOT ROUTINELY USED; AND I SET MYSELF UP FOR A R BASE ENTRY AND FINAL FOR RWY 32R. I MADE MY BASE AND FINAL TFC CALLS; AND AS I DSNDED ON SHORT FINAL; I SAW A LIGHT TWIN PASSING OVERHEAD FROM THE NE TO THE S IN A CLBING TURN. I COMPLETED MY LNDG AND EXITED AT THE TERMINAL. I PARKED THE PLANE; AND DEPARTED THE FIELD WITHIN 10 MINS. THE FOLLOWING WEDNESDAY; WENT OUT TO CLOVER FIELD IN THE AFTERNOON. THE GENERAL MGR OF THE FBO MENTIONED THAT ON THE DAY IN QUESTION ONE OF HIS INSTRUCTORS ALLEGED THAT I HAD ENTERED THE PATTERN; CUT OFF A TWIN ON LNDG FORCING IT TO GO AROUND; WAS TAXIING TOO FAST AND THAT I DIDN'T RESPOND TO ANY RADIO CALLS. I WAS IMMEDIATELY CONCERNED; RECOLLECTED MY THOUGHTS; AND RELAYED THEM TO HIM AS MENTIONED ABOVE. I CAME TO THE CONCLUSION THAT I WAS ON THE WRONG CTAF FREQ; AND THAT I HAD INDEED CAUSED A LIGHT TWIN APCHING ME HEAD-ON USING RWY 14L TO GO AROUND. I NORMALLY CONSIDER MYSELF PRETTY METICULOUS ABOUT TFC SPOTTING AND RADIO DISCIPLINE; AND CAN ONLY SUSPECT THAT I HAD TUNED THE ACFT RADIO TO 122.7 RATHER THAN 122.8 FOR CLOVER. AS I LANDED I SAW ONLY 1 OTHER ACFT OPERATING THAT WAS IN THE RUN-UP AREA FOR RWY 14L. I CAN ONLY ASSUME THAT THIS CONFLICT WAS CAUSED BY MYSELF; PRIMARILY BY USING THE WRONG FREQ. I BELIEVE THAT AS FATIGUED AND DISTRESSED AS I WAS; I SIMPLY SELECTED 122.7 OUT OF SOME DORMANT HABIT. I MAY HAVE BEEN COMPLACENT ABOUT TFC SPOTTING; AS MOST NO RADIO TFC AT CLOVER USES A TURF PARALLEL RWY 32L/14R AND I PRESUMED SINCE THE DOWNWIND AND BASE AND FINAL FOR RWY 32R WERE CLR I WAS SAFE TO MAKE A SHORT BASE ENTRY AND LNDG. AS PIC I AM RESPONSIBLE FOR MY ACTIONS REGARDLESS OF THE CIRCUMSTANCE. I THINK THAT GIVEN THE EXTRANEOUS STRESSORS THAT I WAS UNDER; I PROBABLY SHOULD NOT HAVE BEEN FLYING; BUT GIVEN THAT I CHOSE TO FLY ANYWAY; HAVING A WRITTEN 'FLT PLAN' COULD HAVE BEEN ADVANTAGEOUS FOR ME. WHILE I AM A VFR PLT; I HAVE A SIGNIFICANT AMOUNT OF INST TRAINING; I USUALLY CARRY THE APCH PLATES FOR THE FIELDS THAT I AM FLYING TO AND FROM OR MAY DIVERT TO. IN THE ABSENCE OF USING A WRITTEN 'PLAN' I SHOULD HAVE CONSULTED THE APCH PLATE THAT WAS READILY AVAILABLE ON MY KNEEBOARD. ONCE AGAIN; I WAS GOING TO A FAMILIAR FIELD OF OVER A YEAR AND HAD NO REASON TO SUSPECT A PROB.
