Narrative:

I departed hpn at approximately XA00. ATIS information warned of low level windshear. I climbed to approximately 3000 ft and found smoother air, but over rising terrain and beneath clouds there was heavy turbulence and vertical winds and updrafts. I was monitoring new york approach on 126.4. 10-15 mi from pou, I tuned in pou ATIS. Winds were 280 degrees/16 KTS gusting to 20 KTS and runway 24 in use (ATIS). While descending, I was distraction by a gust and I continued to control the aircraft. It was my intention to switch frequencys to 124.0. I switched frequencys on a KX155, gave a position report and confirmed ATIS. I was given (or heard) 'squawk XXXX.' I entered that code and continued the approach to pou. As I continued a descending approach, I heard other aircraft over the radio. Then there was a great deal of static and then silence. Because of the turbulence, my first concern was to safely fly the aircraft. I continued my approach and continued to broadcast my position as I entered into a 45 degree angle to the downwind. I continued to look for air traffic and a light signal from the pou tower. Seeing no traffic or light signals, I continued my approach while calling my base and final legs. I landed on runway 24 and was able to stop by the first intersection, turned left and was directly in front of the tower. I called ground control on 121.8 and made contact and was given ground clearance and was asked to 'come to the tower.' I wondered why. I was greeted by a man who idented himself as the area supervisor of pou tower and the person on ground control when I landed. He told me that there was a pilot deviation and that 2 aircraft had landed on intersecting runways at the same time. I had landed on runway 24 and another aircraft had requested runway 33 for winds. He said that I was not in radio contact and the tower had tried to get me to 'go around.' failing to contact me, the other aircraft was told to 'go around' but did not respond either. There was the possibility of a collision. I told him about my listening to ATIS, getting a squawk code, losing radio contact and flying the broadcast approach to runway 24 in turbulent conditions. I returned to my aircraft and saw that the stored frequency I was transmitting on was not 124.0, but 126.4. I realized that during the turbulence my attention was diverted and I had not put in the frequency I thought I had.

Title: 2 ACFT LAND ON INTERSECTING RWYS AT POU, NY. ONE WAS GIVEN A GAR BY TWR, BUT DID NOT EXECUTE IT. THE OTHER WAS ON THE WRONG FREQ AND SAW NO LIGHT SIGNALS.

Narrative: I DEPARTED HPN AT APPROX XA00. ATIS INFO WARNED OF LOW LEVEL WINDSHEAR. I CLBED TO APPROX 3000 FT AND FOUND SMOOTHER AIR, BUT OVER RISING TERRAIN AND BENEATH CLOUDS THERE WAS HVY TURB AND VERT WINDS AND UPDRAFTS. I WAS MONITORING NEW YORK APCH ON 126.4. 10-15 MI FROM POU, I TUNED IN POU ATIS. WINDS WERE 280 DEGS/16 KTS GUSTING TO 20 KTS AND RWY 24 IN USE (ATIS). WHILE DSNDING, I WAS DISTR BY A GUST AND I CONTINUED TO CTL THE ACFT. IT WAS MY INTENTION TO SWITCH FREQS TO 124.0. I SWITCHED FREQS ON A KX155, GAVE A POS RPT AND CONFIRMED ATIS. I WAS GIVEN (OR HEARD) 'SQUAWK XXXX.' I ENTERED THAT CODE AND CONTINUED THE APCH TO POU. AS I CONTINUED A DSNDING APCH, I HEARD OTHER ACFT OVER THE RADIO. THEN THERE WAS A GREAT DEAL OF STATIC AND THEN SILENCE. BECAUSE OF THE TURB, MY FIRST CONCERN WAS TO SAFELY FLY THE ACFT. I CONTINUED MY APCH AND CONTINUED TO BROADCAST MY POS AS I ENTERED INTO A 45 DEG ANGLE TO THE DOWNWIND. I CONTINUED TO LOOK FOR AIR TFC AND A LIGHT SIGNAL FROM THE POU TWR. SEEING NO TFC OR LIGHT SIGNALS, I CONTINUED MY APCH WHILE CALLING MY BASE AND FINAL LEGS. I LANDED ON RWY 24 AND WAS ABLE TO STOP BY THE FIRST INTXN, TURNED L AND WAS DIRECTLY IN FRONT OF THE TWR. I CALLED GND CTL ON 121.8 AND MADE CONTACT AND WAS GIVEN GND CLRNC AND WAS ASKED TO 'COME TO THE TWR.' I WONDERED WHY. I WAS GREETED BY A MAN WHO IDENTED HIMSELF AS THE AREA SUPVR OF POU TWR AND THE PERSON ON GND CTL WHEN I LANDED. HE TOLD ME THAT THERE WAS A PLTDEV AND THAT 2 ACFT HAD LANDED ON INTERSECTING RWYS AT THE SAME TIME. I HAD LANDED ON RWY 24 AND ANOTHER ACFT HAD REQUESTED RWY 33 FOR WINDS. HE SAID THAT I WAS NOT IN RADIO CONTACT AND THE TWR HAD TRIED TO GET ME TO 'GO AROUND.' FAILING TO CONTACT ME, THE OTHER ACFT WAS TOLD TO 'GO AROUND' BUT DID NOT RESPOND EITHER. THERE WAS THE POSSIBILITY OF A COLLISION. I TOLD HIM ABOUT MY LISTENING TO ATIS, GETTING A SQUAWK CODE, LOSING RADIO CONTACT AND FLYING THE BROADCAST APCH TO RWY 24 IN TURBULENT CONDITIONS. I RETURNED TO MY ACFT AND SAW THAT THE STORED FREQ I WAS XMITTING ON WAS NOT 124.0, BUT 126.4. I REALIZED THAT DURING THE TURB MY ATTN WAS DIVERTED AND I HAD NOT PUT IN THE FREQ I THOUGHT I HAD.
