Narrative:

Inadvertently landed on runway 16 instead of runway 34 at laughlin bullhead, az. Flew from kingman, az, to laughlin bullhead, az. On the way to bullhead, I attempted to contact unicom, without success, to find out the WX and runway. Not being able to contact unicom, I contacted the tower about 5 mi from airport. Tower said to standby. Instead of circling I continued towards the airport, believing I had 2 way communication. I then contacted tower and said I was on the 45 degree entering downwind (I believe, but can't say for sure, I said for runway 16 to tower). Tower said to contact him at mid-field. I contacted tower at mid-field. I landed on runway 16. After landing tower said runway 34 was in use. No planes were landing or taking off at the time I landed on runway 16. I think this problem arose because I was tired, having flown for 3 hours from camarillo, ca, to kingman, az. Further, the communication radios had a memory for 3 frequencys to be inserted on each communication line. I punched in unicom but failed to notice that the frequency of unicom did not stay. It went back to the previously set frequency. I did not notice this until I got close to the airport. That is the reason unicom did not respond. I was on the wrong frequency. The next time I will take my time and fly over the airport or circle to get the proper communication flow between the tower and myself. Fortunately, there was no conflicting aircraft in the vicinity.

Title: THE RPTR CALLED TWR AND WAS TOLD TO STANDBY. THE RPTR CONTINUED ON INTO THE CLASS D AIRSPACE. THE RPTR CALLED ON THE 45 DEG TO THE DOWNWIND THINKING HE SAID FOR RWY 16. THE TWR SAID FOR HIM TO RPT MID-FIELD, WHICH THE RPTR DID, AND APPARENTLY GOT LNDG CLRNC. AFTER LNDG THE TWR ADVISED RWY 34 WAS THE RWY IN USE.

Narrative: INADVERTENTLY LANDED ON RWY 16 INSTEAD OF RWY 34 AT LAUGHLIN BULLHEAD, AZ. FLEW FROM KINGMAN, AZ, TO LAUGHLIN BULLHEAD, AZ. ON THE WAY TO BULLHEAD, I ATTEMPTED TO CONTACT UNICOM, WITHOUT SUCCESS, TO FIND OUT THE WX AND RWY. NOT BEING ABLE TO CONTACT UNICOM, I CONTACTED THE TWR ABOUT 5 MI FROM ARPT. TWR SAID TO STANDBY. INSTEAD OF CIRCLING I CONTINUED TOWARDS THE ARPT, BELIEVING I HAD 2 WAY COM. I THEN CONTACTED TWR AND SAID I WAS ON THE 45 DEG ENTERING DOWNWIND (I BELIEVE, BUT CAN'T SAY FOR SURE, I SAID FOR RWY 16 TO TWR). TWR SAID TO CONTACT HIM AT MID-FIELD. I CONTACTED TWR AT MID-FIELD. I LANDED ON RWY 16. AFTER LNDG TWR SAID RWY 34 WAS IN USE. NO PLANES WERE LNDG OR TAKING OFF AT THE TIME I LANDED ON RWY 16. I THINK THIS PROB AROSE BECAUSE I WAS TIRED, HAVING FLOWN FOR 3 HRS FROM CAMARILLO, CA, TO KINGMAN, AZ. FURTHER, THE COM RADIOS HAD A MEMORY FOR 3 FREQS TO BE INSERTED ON EACH COM LINE. I PUNCHED IN UNICOM BUT FAILED TO NOTICE THAT THE FREQ OF UNICOM DID NOT STAY. IT WENT BACK TO THE PREVIOUSLY SET FREQ. I DID NOT NOTICE THIS UNTIL I GOT CLOSE TO THE ARPT. THAT IS THE REASON UNICOM DID NOT RESPOND. I WAS ON THE WRONG FREQ. THE NEXT TIME I WILL TAKE MY TIME AND FLY OVER THE ARPT OR CIRCLE TO GET THE PROPER COM FLOW BTWN THE TWR AND MYSELF. FORTUNATELY, THERE WAS NO CONFLICTING ACFT IN THE VICINITY.
