Narrative:

I was PIC on this training flight in the student's own aircraft. We departed hpn, and because hpn was very busy decided to fly to stewart to do a series of lndgs there. After having asked for a frequency change from hpn tower, we contacted ny approach (126.4) and were assigned a discrete squawk code. We received advisories until approximately 10 mi south of stewart where we were advised that radar service was terminated. We then contacted stewart tower on 121.0. I understood that we were cleared for a straight in landing on runway 34. We acknowledged and proceeded to continue the approach to runway 34, and we landed uneventfully, coming to a full stop before crossing runway 9-27. Tower did not initiate a transmission and I then called tower, asking if we could taxi for a takeoff. Tower responded that we had not been cleared to land and instead were asked to report on 3 mi final. I apologized, tower then had us taxi to the beginning of runway 16, where we did a 360 degree turn, and were subsequently cleared for takeoff. Contributing factors: the plane we used is very noisy and the transmission was not understood at all. I did think that we were cleared to land. How this could have been avoided: use earphones, which we will do from now on. Also, the tower controller must have seen us for at least 3 mi out on a straight in approach that he told us to do. He could have easily stopped us from landing by making just 1 call to us.

Title: GA SMA UNAUTH LNDG DURING A TRAINING FLT.

Narrative: I WAS PIC ON THIS TRNING FLT IN THE STUDENT'S OWN ACFT. WE DEPARTED HPN, AND BECAUSE HPN WAS VERY BUSY DECIDED TO FLY TO STEWART TO DO A SERIES OF LNDGS THERE. AFTER HAVING ASKED FOR A FREQ CHANGE FROM HPN TWR, WE CONTACTED NY APCH (126.4) AND WERE ASSIGNED A DISCRETE SQUAWK CODE. WE RECEIVED ADVISORIES UNTIL APPROX 10 MI S OF STEWART WHERE WE WERE ADVISED THAT RADAR SVC WAS TERMINATED. WE THEN CONTACTED STEWART TWR ON 121.0. I UNDERSTOOD THAT WE WERE CLRED FOR A STRAIGHT IN LNDG ON RWY 34. WE ACKNOWLEDGED AND PROCEEDED TO CONTINUE THE APCH TO RWY 34, AND WE LANDED UNEVENTFULLY, COMING TO A FULL STOP BEFORE XING RWY 9-27. TWR DID NOT INITIATE A XMISSION AND I THEN CALLED TWR, ASKING IF WE COULD TAXI FOR A TKOF. TWR RESPONDED THAT WE HAD NOT BEEN CLRED TO LAND AND INSTEAD WERE ASKED TO RPT ON 3 MI FINAL. I APOLOGIZED, TWR THEN HAD US TAXI TO THE BEGINNING OF RWY 16, WHERE WE DID A 360 DEG TURN, AND WERE SUBSEQUENTLY CLRED FOR TKOF. CONTRIBUTING FACTORS: THE PLANE WE USED IS VERY NOISY AND THE XMISSION WAS NOT UNDERSTOOD AT ALL. I DID THINK THAT WE WERE CLRED TO LAND. HOW THIS COULD HAVE BEEN AVOIDED: USE EARPHONES, WHICH WE WILL DO FROM NOW ON. ALSO, THE TWR CTLR MUST HAVE SEEN US FOR AT LEAST 3 MI OUT ON A STRAIGHT IN APCH THAT HE TOLD US TO DO. HE COULD HAVE EASILY STOPPED US FROM LNDG BY MAKING JUST 1 CALL TO US.
