PLT OF C150 TRANSGRESSED W EDGE OF DC ADIZ. FORCED TO LAND BY CUSTOMS ACFT.

Narrative

THIS FLT ORIGINATED FROM DAN ARPT; TO TERMINATE AT OKV. THE FLT WAS TO GO NE STAYING TO THE R OF LYH. I GAVE MYSELF A NARROW PASSAGE BTWN THE MOUNTAINS TO MY L AND 30 MI ARC OF WASHINGTON ADIZ. MY PARTNER AND I DECIDED TO USE OUR SECOND HAND-HELD GPS TO KEEP US ON COURSE. I DID NOT REALIZE WHEN MY PARTNER HUNG THE HANDHELD GPS ON THE REARVIEW MIRROR; HE UNKNOWINGLY TURNED OFF THE MASTER SWITCH; WHICH IS A PUSH/PULL SWITCH DIRECTLY BELOW THE REARVIEW MIRROR. WHEN NEARING OKV; I REALIZED THE RADIO AND XPONDER WERE NOT WORKING AT ABOUT THE SAME TIME I WAS INTERCEPTED BY THE UNITED STATES CUSTOMS CITATION. I CHKED AND TURNED THE MASTER BACK ON! I WAS TOLD TO LAND AT OKV AND WAS TOLD I HAD ENTERED THE WESTERLY EDGES OF THE ADIZ. IN MY EFFORT TO STAY CLR OF THE MOUNTAINS; AND THE ADIZ AND NAV THIS AREA I APPARENTLY DID NOT ALLOW FOR THE CHANGING WINDS WHILE FLYING CLOSE TO THE MOUNTAIN RIDGES. KNOWING FULL WELL OF THE TFR AREAS; I DID NOT PURPOSELY IGNORE ANY OF THE FAA RESTR. THIS IS SOMETHING THAT I DO NOT TAKE LIGHTLY; AND I UNDERSTAND THE NEED FOR THE SECURITY AND WOULD NOT DELIBERATELY VIOLATE OR IGNORE THEM. I REGRET THIS OVERSIGHT AND WILL NOT UNDER ANY CIRCUMSTANCES ALLOW THIS TO HAPPEN AGAIN. I WAS INSTRUCTED BY THE CUSTOMS AGENT TO CALL POTOMAC TRACON. I DID SO IMMEDIATELY.
