Narrative:

This incident is difficult to discuss since there seems to be little to discuss, but pilot planning/judgement. The airport(south) in question is on the west coast of alaska. The airspace is uncontrolled, there is no instrument procedure and no WX reporting at either airport. Flight was launched on an IFR flight plan, which was cancelled with ATC when the airport environment became visible in excellent VFR conditions. I have been to both villages numerous times, but the most recent was more than 10 yrs ago. The villages are about 5 mi apart and from the moment I learned I was going to ZZZ1, I made the mistake of believing I was going to ZZZ. After I made that initial assumption, nothing in the ensuing flight persuaded me of my mistake until I had landed without incident and been informed by villagers that I was in ZZZ and not ZZZ1. Embarrassed and concerned for the timeliness of the rest of my trip, I immediately departed and landed at my intended destination without incident. The issue however is the size of the runway at ZZZ which does not meet our company requirements for length for either landing or takeoff. Although I had made reasonable efforts to determine the location and condition of the destination runway before and during the flight, brief discussion with a pilot who was more familiar and had been there only days before, consulting the 'ak' supplement, WAC charts, and GPS database -- none of this information was enough to override my initial assumption that I understood which of these 2 landing strips was my actual destination. I blame this on simple overconfidence for a lack of a better explanation. Experience it seems is no replacement for doing one's homework.

Title: BEECH 1900 CREW LANDED AT WRONG ARPT. THE CREW DEPARTED IN NON COMPLIANCE OF COMPANY REGS FOR TKOF OR LNDG LENGTH.

Narrative: THIS INCIDENT IS DIFFICULT TO DISCUSS SINCE THERE SEEMS TO BE LITTLE TO DISCUSS, BUT PLT PLANNING/JUDGEMENT. THE ARPT(S) IN QUESTION IS ON THE WEST COAST OF ALASKA. THE AIRSPACE IS UNCTLED, THERE IS NO INST PROC AND NO WX RPTING AT EITHER ARPT. FLT WAS LAUNCHED ON AN IFR FLT PLAN, WHICH WAS CANCELLED WITH ATC WHEN THE ARPT ENVIRONMENT BECAME VISIBLE IN EXCELLENT VFR CONDITIONS. I HAVE BEEN TO BOTH VILLAGES NUMEROUS TIMES, BUT THE MOST RECENT WAS MORE THAN 10 YRS AGO. THE VILLAGES ARE ABOUT 5 MI APART AND FROM THE MOMENT I LEARNED I WAS GOING TO ZZZ1, I MADE THE MISTAKE OF BELIEVING I WAS GOING TO ZZZ. AFTER I MADE THAT INITIAL ASSUMPTION, NOTHING IN THE ENSUING FLT PERSUADED ME OF MY MISTAKE UNTIL I HAD LANDED WITHOUT INCIDENT AND BEEN INFORMED BY VILLAGERS THAT I WAS IN ZZZ AND NOT ZZZ1. EMBARRASSED AND CONCERNED FOR THE TIMELINESS OF THE REST OF MY TRIP, I IMMEDIATELY DEPARTED AND LANDED AT MY INTENDED DEST WITHOUT INCIDENT. THE ISSUE HOWEVER IS THE SIZE OF THE RWY AT ZZZ WHICH DOES NOT MEET OUR COMPANY REQUIREMENTS FOR LENGTH FOR EITHER LNDG OR TKOF. ALTHOUGH I HAD MADE REASONABLE EFFORTS TO DETERMINE THE LOCATION AND CONDITION OF THE DEST RWY BEFORE AND DURING THE FLT, BRIEF DISCUSSION WITH A PLT WHO WAS MORE FAMILIAR AND HAD BEEN THERE ONLY DAYS BEFORE, CONSULTING THE 'AK' SUPPLEMENT, WAC CHARTS, AND GPS DATABASE -- NONE OF THIS INFO WAS ENOUGH TO OVERRIDE MY INITIAL ASSUMPTION THAT I UNDERSTOOD WHICH OF THESE 2 LNDG STRIPS WAS MY ACTUAL DEST. I BLAME THIS ON SIMPLE OVERCONFIDENCE FOR A LACK OF A BETTER EXPLANATION. EXPERIENCE IT SEEMS IS NO REPLACEMENT FOR DOING ONE'S HOMEWORK.
