Narrative:

WX brief by hawthorne -- cavu. No airmets, no sigmets. Ground (VOR) OTS. Departed sba to gvo direct mqo direct prb (VOR). Lax flight following announced traffic 1 mi, same altitude and direction as me and I am overtaking that traffic (a sky lane), therefore, I deviate 15 degrees to right by passing mqo VOR direct prb at 6500 ft. I see 'the' airport on my left which I believe to be prb and announce on CTAF 123.0, but I land at sbp without landing clearance because I think I am at sbp. Upon landing, tower asks me to talk with them, which I do, and after a pleasant discussion, they say they will just consider it a 'learning experience and forget it.' I still can't believe I did such a stupid thing. The WX was cavu with 30 mi visibility. I had pilotage going, vors, LORAN and GPS. All instruments telling me correctly, but when I saw the airport on my left (it was sbp and I thought it was prb) because I thought I could see 30 mi visibility. However I landed with traffic runway 29 at sbp without a landing clearance. What to do in future to prevent: 1) look at airport diagram much more carefully on sectional chart. 2) believe my navigation instruments, ie, VOR, DME, LORAN and GPS which were all accurate! 3) ask flight following to confirm. 4) if in doubt, overfly the airport at altitude to confirm which airport it is (about class D airspace) and talk to approach and tower.

Title: PLT OF SMA USING PILOTAGE WITH VOR, LORAN AND GPS SIGHTS WRONG ARPT AND LANDS WITHOUT CLRNC.

Narrative: WX BRIEF BY HAWTHORNE -- CAVU. NO AIRMETS, NO SIGMETS. GND (VOR) OTS. DEPARTED SBA TO GVO DIRECT MQO DIRECT PRB (VOR). LAX FLT FOLLOWING ANNOUNCED TFC 1 MI, SAME ALT AND DIRECTION AS ME AND I AM OVERTAKING THAT TFC (A SKY LANE), THEREFORE, I DEVIATE 15 DEGS TO R BY PASSING MQO VOR DIRECT PRB AT 6500 FT. I SEE 'THE' ARPT ON MY L WHICH I BELIEVE TO BE PRB AND ANNOUNCE ON CTAF 123.0, BUT I LAND AT SBP WITHOUT LNDG CLRNC BECAUSE I THINK I AM AT SBP. UPON LNDG, TWR ASKS ME TO TALK WITH THEM, WHICH I DO, AND AFTER A PLEASANT DISCUSSION, THEY SAY THEY WILL JUST CONSIDER IT A 'LEARNING EXPERIENCE AND FORGET IT.' I STILL CAN'T BELIEVE I DID SUCH A STUPID THING. THE WX WAS CAVU WITH 30 MI VISIBILITY. I HAD PILOTAGE GOING, VORS, LORAN AND GPS. ALL INSTS TELLING ME CORRECTLY, BUT WHEN I SAW THE ARPT ON MY L (IT WAS SBP AND I THOUGHT IT WAS PRB) BECAUSE I THOUGHT I COULD SEE 30 MI VISIBILITY. HOWEVER I LANDED WITH TFC RWY 29 AT SBP WITHOUT A LNDG CLRNC. WHAT TO DO IN FUTURE TO PREVENT: 1) LOOK AT ARPT DIAGRAM MUCH MORE CAREFULLY ON SECTIONAL CHART. 2) BELIEVE MY NAV INSTS, IE, VOR, DME, LORAN AND GPS WHICH WERE ALL ACCURATE! 3) ASK FLT FOLLOWING TO CONFIRM. 4) IF IN DOUBT, OVERFLY THE ARPT AT ALT TO CONFIRM WHICH ARPT IT IS (ABOUT CLASS D AIRSPACE) AND TALK TO APCH AND TWR.
