Ugh... I'm beating myself up as I feel I made a pretty serious mistake over the weekend. I'm a PPL trying to build up XC hours trying to work towards my instrument. Over the weekend I did a short XC to an extremely remote desert airport which is a nice little flight. I do flight following all the way there, uneventful. 15 miles out I get the ASOS and it says winds calm. After canceling flight following, I switch over to the CTAF.
This is where I started to get a little overwhelmed and I start making mistakes. I had waited a little longer to start my descent so I was approaching a little faster than usual. I have made this flight several times before and the winds are usually from the east so I planned my normal pattern entry to cross the field, make a right turn and enter the left pattern for the easterly runway. As I'm approaching I'm using my standard communications; someone on the ground radios to say the winds are actually out of the west and at at least 10 knots as the windsock is almost straight out. At that same moment, another pilot radioed announcing they were 3 miles to the west and inbound to land. For some reason this last minute information really overloaded me and I just went into autopilot. For some reason, I still just had "left pattern" baked into my brain. Instead of continuing to cross the field I entered at a 45 into a left pattern for the westerly runway. (sigh). I fly it normally and on final the traffic that was a few miles out now announces they are on a right downwind. My heart sinks. I realized my mistake, and although I am mortified, I decide to continue the landing and go on with my trip back to my base.
Afterward, I debriefed myself trying to isolate what happened, and how to prevent this kind of mistake again. I take safety and procedure very seriously. I shudder to think what might have happened if there was a NORDO in the pattern...
My question is should I be worried? I've never made this type of mistake before and am frankly expecting a call from the FSDO. It's not a populated area and there is very little traffic there but still...
