Narrative

CHKED WX WITH BUFFALO FSS FOR FLT FROM NIAGARA FALLS (IAG) NY; TO ST CATHERINES; ONTARIO; NO NOTAMS GIVEN BEFORE XING THE NIAGARA RIVER WE ANNOUNCED OUR INTENTIONS ON 119.00. ST CATHERINES IS A CTL ZONE IN OP XXF00-XXOO ACCORDING TO THE CURRENT DETROIT SECTIONAL. WE OVER FLEW THE ARPT; MIDFIELD AT 2500 MSL TO THE N AND PROCEEDED TO XWIND; DOWNWIND BASE AND FINAL AND DID A TOUCH AND GO. INTENTIONS BROADCAST ON EACH LEG. ON THE SECOND DOWNWIND LEG THE RWY LIGHTS WENT OUT. THERE IS NO *L HERE BUT I CLICKED THE MICROPHONE 5 TIMES THEN 7 TIMES. THIS BROUGHT A RESPONSE FROM THE TWR TO TUNE 123.45 WHICH I DID. TWR INFORMED ME I WAS IN VIOLATION OF THEIR AIRSPACE AND TOUCH AND GOES WERE ILLEGAL; ALSO THAT THE TWR WAS NO LONGER IN OP. HE THEN TURNED RWY LIGHTS BACK ON AND CLRED US FOR A TOUCH AND GO. MY RESPONSE WAS TO CONFIRM THAT THE CTL ZONE OPERATED FROM XF00-XX00 PER CURRENT DETROIT SECTIONAL AND IF TOUCH AND GOES WERE ILLEGAL WE WOULD PROCEED BACK TO NIAGARA; AND THAT I WOULD CERTAINLY PASS THIS INFO ALONG TO OTHER CFI'S AT NIAGARA. UPON LNDG AT NIAGARA; TWR INFORMED ME THAT ST CATHERINES HAD CALLED TO ADVISE OF THE NEW FREQ (123.45) AND TOUCH AND GOES ARE ILLEGAL UNLESS CLRED BY CUSTOMS AND SUGGESTED LOW APCHS WITH PRIOR PERMISSION. IN THE PAST WE HAVE USED THIS ARPT FOR TOUCH AND GOES DURING THE DAY WITH TWR CLRNC AND NEVER CLRED IT WITH CUSTOMS. ALSO AT NIGHT TIME; BY ANNOUNCING OUR INTENTIONS ON THE TWR FREQ. I HAVE TO QUESTION IF SOMEONE WAS IN THE TWR WHY THEY DID NOT QUESTION OUR INTENTIONS SOONER THAN THE SECOND PATTERN AROUND THE FIELD. WE WERE CERTAINLY VISIBLE WITH NAV; ANTI-COLLISION AND LNDG LIGHTS ALL WORKING AT THE TIME. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO. RPTR STATES COMPLETELY ASTOUNDED BY THESE PROCS. NO RESPONSE FROM TWR WHILE IN PATTERN; THEN TURNING OFF RWY LIGHTS AND ANNOUNCING TWR CLOSED. RPTR HAS NO IDEA WHO MADE THE COMMENTS. RPTR NOTICED NEW SECTIONAL CHART HAS A NOTE REF FSS TO CONTACT AND ARPT PICTURED AS UNCTLED; SO NEW PROCS ARE IN EFFECT. INTENDS TO FOLLOW UP WITH FAA AND GET CANADIAN CUSTOMS INFO. RPTR COULD FIND NO NOTAM INFO.
