Narrative:

While returning to the originating airport after a scenic flight with family, it had become dark. I had reviewed the flight earlier and decided to just track the NDB (which was on the field) inbound to the airport. Approximately 20 mi from the airport the ADF needle swung to a radial bearing of 005 degrees. I tracked that in, or thought to have been tracking it in, until I realized I was over a city that was 20 mi past my destination airport. At some point the ADF quit working. I made a 180 degree turn with some disorientation as to the location of my destination airport. I attempted to call FSS on several frequencys with no luck. I had to resort to using 121.5. FSS then gave me the frequency of a local approach controller. I received radar vectors from him and landed uneventfully. I was lucky enough to not have penetrated any airspace. Some contributing factors were: 1) my relaxed attitude about finding a small, uncontrolled airport at night. 2) my depending only on my ADF. 3) my disorientation when I wasn't where I thought I should have been.

Title: PA28 PLT BECOMES DISORIENTED WHEN UTILIZING ADF TO FIND ARPT. PLT BECOMES AWARE OF EQUIP MALFUNCTION, DECLARES EMER WITH BDR FSS, WHO XFERS PLT TO BDL APCH CTL. ACFT VECTORED BACK TO DEST.

Narrative: WHILE RETURNING TO THE ORIGINATING ARPT AFTER A SCENIC FLT WITH FAMILY, IT HAD BECOME DARK. I HAD REVIEWED THE FLT EARLIER AND DECIDED TO JUST TRACK THE NDB (WHICH WAS ON THE FIELD) INBOUND TO THE ARPT. APPROX 20 MI FROM THE ARPT THE ADF NEEDLE SWUNG TO A RADIAL BEARING OF 005 DEGS. I TRACKED THAT IN, OR THOUGHT TO HAVE BEEN TRACKING IT IN, UNTIL I REALIZED I WAS OVER A CITY THAT WAS 20 MI PAST MY DEST ARPT. AT SOME POINT THE ADF QUIT WORKING. I MADE A 180 DEG TURN WITH SOME DISORIENTATION AS TO THE LOCATION OF MY DEST ARPT. I ATTEMPTED TO CALL FSS ON SEVERAL FREQS WITH NO LUCK. I HAD TO RESORT TO USING 121.5. FSS THEN GAVE ME THE FREQ OF A LCL APCH CTLR. I RECEIVED RADAR VECTORS FROM HIM AND LANDED UNEVENTFULLY. I WAS LUCKY ENOUGH TO NOT HAVE PENETRATED ANY AIRSPACE. SOME CONTRIBUTING FACTORS WERE: 1) MY RELAXED ATTITUDE ABOUT FINDING A SMALL, UNCTLED ARPT AT NIGHT. 2) MY DEPENDING ONLY ON MY ADF. 3) MY DISORIENTATION WHEN I WASN'T WHERE I THOUGHT I SHOULD HAVE BEEN.
