An small aircraft pilot navigating with GPS flies into a sua. The antenna on the GPS is loose so his GPS is unreliable and he has no backup to assure navigation accuracy.

Narrative:
I was flying with the GPS from north of the ric VOR to rdu. The GPS lost its coverage. I had been talking to my passenger and didn't notice that the antenna had come loose. When I did get it together and it came back on-line, the message notice came on. I switched to it, which told me that a sua was coming up. I got out the chart and noticed R6602-abc. I immediately headed east and tuned in the lvl VOR. It centered on about a 210 degree heading to the station. The DME read 11 NM. I believe I probably went through R6602B. I learned today to not rely on GPS without backing it up with good pilotage and dead reckoning when in such good VMC. I needed to keep up with my progress with the charts.

Title: AN SMA PLT NAVING WITH GPS FLIES INTO A SUA. THE ANTENNA ON THE GPS IS LOOSE SO HIS GPS IS UNRELIABLE AND HE HAS NO BACKUP TO ASSURE NAV ACCURACY.
Narrative: I WAS FLYING WITH THE GPS FROM N OF THE RIC VOR TO RDU. THE GPS LOST ITS COVERAGE. I HAD BEEN TALKING TO MY PAX AND DIDN'T NOTICE THAT THE ANTENNA HAD COME LOOSE. WHEN I DID GET IT TOGETHER AND IT CAME BACK ON-LINE, THE MESSAGE NOTICE CAME ON. I SWITCHED TO IT, WHICH TOLD ME THAT A SUA WAS COMING UP. I GOT OUT THE CHART AND NOTICED R6602-ABC. I IMMEDIATELY HEADED E AND TUNED IN THE LVL VOR. IT CTRED ON ABOUT A 210 DEG HDG TO THE STATION. THE DME READ 11 NM. I BELIEVE I PROBABLY WENT THROUGH R6602B. I LEARNED TODAY TO NOT RELY ON GPS WITHOUT BACKING IT UP WITH GOOD PILOTAGE AND DEAD RECKONING WHEN IN SUCH GOOD VMC. I NEEDED TO KEEP UP WITH MY PROGRESS WITH THE CHARTS.
