Narrative:

Landed at trenton - robbinsville airport to get a flight plan to enter the ny tfr. Received flight plan and took off to activate in the air. Had trouble speaking with approach control, but finally got them and received transponder code, was told I was already inside the 30 mile tfr. Then proceeded at 3500 ft over nj, towards the hudson river. Was told to stay at 3500 ft to clear teb air traffic. Was handed over to another controller, which I could not understand. I heard the other aircraft, but not the controller too well. At this point, I was told to call a number when I landed. I was told that my transponder was not working the last 6 miles going toward the river. I finally landed at my seaplane base 6n6 (evers seaplane base) on the water. They couldn't understand that I was landing in the water even though I told them I was a seaplane. Have been told that the lake amphibian transponder antenna is located on a bad spot on the wing and sometimes it does not send a good signal (blocked by wing float) in certain conditions. I knew I was wrong after entering the tfr, but the controller said to keep going on a heading and I thought I was ok after that until he told me to call the FAA when I landed. I hope to change to a different transponder set so this will not happen again. Also I'm mainly a seaplane pilot and have little experience in this type of flight plan tfr. I probably should have received some instruction before I tried to do this. Was just trying to get home.

Title: A VFR DEP LA-4 LAKE PVT PLT EXPERIENCED AN UNAUTH TFR PENETRATION OF THE NY TFR AT 2000 FT, 30 SW OF EWR, NJ AND A MALFUNCTION OF HIS XPONDER AFTER PASSING TEB, NJ.

Narrative: LANDED AT TRENTON - ROBBINSVILLE ARPT TO GET A FLT PLAN TO ENTER THE NY TFR. RECEIVED FLT PLAN AND TOOK OFF TO ACTIVATE IN THE AIR. HAD TROUBLE SPEAKING WITH APCH CTL, BUT FINALLY GOT THEM AND RECEIVED XPONDER CODE, WAS TOLD I WAS ALREADY INSIDE THE 30 MILE TFR. THEN PROCEEDED AT 3500 FT OVER NJ, TOWARDS THE HUDSON RIVER. WAS TOLD TO STAY AT 3500 FT TO CLR TEB AIR TFC. WAS HANDED OVER TO ANOTHER CTLR, WHICH I COULD NOT UNDERSTAND. I HEARD THE OTHER ACFT, BUT NOT THE CTLR TOO WELL. AT THIS POINT, I WAS TOLD TO CALL A NUMBER WHEN I LANDED. I WAS TOLD THAT MY XPONDER WAS NOT WORKING THE LAST 6 MILES GOING TOWARD THE RIVER. I FINALLY LANDED AT MY SEAPLANE BASE 6N6 (EVERS SEAPLANE BASE) ON THE WATER. THEY COULDN'T UNDERSTAND THAT I WAS LNDG IN THE WATER EVEN THOUGH I TOLD THEM I WAS A SEAPLANE. HAVE BEEN TOLD THAT THE LAKE AMPHIBIAN XPONDER ANTENNA IS LOCATED ON A BAD SPOT ON THE WING AND SOMETIMES IT DOES NOT SEND A GOOD SIGNAL (BLOCKED BY WING FLOAT) IN CERTAIN CONDITIONS. I KNEW I WAS WRONG AFTER ENTERING THE TFR, BUT THE CTLR SAID TO KEEP GOING ON A HDG AND I THOUGHT I WAS OK AFTER THAT UNTIL HE TOLD ME TO CALL THE FAA WHEN I LANDED. I HOPE TO CHANGE TO A DIFFERENT XPONDER SET SO THIS WILL NOT HAPPEN AGAIN. ALSO I'M MAINLY A SEAPLANE PLT AND HAVE LITTLE EXPERIENCE IN THIS TYPE OF FLT PLAN TFR. I PROBABLY SHOULD HAVE RECEIVED SOME INSTRUCTION BEFORE I TRIED TO DO THIS. WAS JUST TRYING TO GET HOME.
