GA SMA UNAUTH PENETRATION OF AIRSPACE.

Narrative

PROB DESCRIPTION/CORRECTIVE ACTIONS: I AM NEW PVT PLT AND WAS RETURNING FROM A LCL SCENIC FLT WITH MY WIFE. IT WAS GETTING DARKER QUICKER THAN EXPECTED AND I DECIDED TO RETURN BACK TO SCHENECTADY ARPT (FROM WHICH I STARTED OUT FROM). I WAS OVER SARATOGA LAKE; AND RPTED TO SCH THAT I WAS INBND FOR LNDG. I HEADED APPROX 225 DEGS; WHICH WOULD HEAD ME TOWARD SCH (RWY 4 WAS ACTIVE). I SAW WHAT I BELIEVED TO BE SCH'S BEACON; AND THEN DIRECTED THE PLANE IN THAT DIRECTION. I WAS UNAWARE THAT I WAS HEADING TOWARD ALB AND CONSEQUENTLY THE ARSA; UNTIL I MADE OUT THE ARPT AND WAS PARALLEL TO RWY 19-37. HAVING CALLED SCH TWR MOMENTS BEFORE TO RPT I WAS ON THE DOWNWIND; WHEN I REALIZED WHERE I WAS; I NOTIFIED SCH AND THEY GAVE ME ALB APCH FREQ. I THEN IMMEDIATELY NOTIFIED APCH AND THEY VECTORED ME BACK TO SCH. CONTRIBUTING FACTORS: FROM MY POS; SARATOGA LAKE; I WAS SITUATED E OF SCH AND W OF ALB. I COULD NOT DISCERN THE BEACON AT SCH. IT IS OBSCURED FROM VIEW DUE TO ITS SITUATION IN TREES. THE ONLY WHITE/GREEN I MADE OUT WAS ALB'S. NOT KNOWING THAT SCH'S BEACON WOULD BE OBSCURED; BELIEVED IT WAS SCH'S. IN ADDITION; I HAD NEVER BEEN IN AREA E OF SCH BEFORE; FOR DURING MY FLT TRNING; I WAS LIMITED TO THE NW PRACTICE AREA; WHERE SHC'S BEACON CAN BE SEEN REASONABLY WELL; THOUGH I WAS NEVER OUT THERE THAT LATE. UPON CONFERRING WITH MY FLT INSTR; HE ACKNOWLEDGED THE PROB WITH THE OBSCURED BEACON AND MENTIONED THAT OTHER PEOPLE HAVE HAD PROBS LOCATING IT BECAUSE OF TREE OBSCURATION WHICH MAKES IT HARD TO SEE FROM DIFFERENT APCH ANGLES. DURING THIS INCIDENT I CONTINUED TO REMAIN; AS ALWAYS; EXTREMELY VIGILANT FOR OTHER ACFT AND WAS ALERT TO ANY POSSIBLE HAZARDS TO MYSELF OR OTHER PEOPLE AND PROPERTY.
