Narrative:

On may/sat/94, approximately XA30 local, 4 of us flying on an instrument flight plan from mlb to our destination, albert whittied (spg). We were cruising at an altitude of 6000 ft as we neared the east side of the tampa bay area. Tampa approach cleared us down to 3000 ft and, soon after, was trying to get us under the cloud layer for a visual approach. We were approximately 5 mi away from spg at 1600 ft for the visual to runway 36 when approach told us to contact tower (no frequency). I was working radios and had already put in standby 120.4 (published tower frequency). When I reported left base runway 36, nobody replied. After 3 tires, I told the PIC I could not contact tower and I felt we should contact approach again to let someone know of our situation (now approximately 3 mi east, 'no contact'). Approach quickly said tower changed to 124.4 and to call back, as soon as possible. We did and reached them. The tower operator said we had violated their airspace and cleared us to land -- being 'final traffic' (very unsafe condition). In all current published charts, facility, directory, and approach plates state the incorrect frequency, and as far as our WX briefings we remember no such mention of NOTAMS. My suggestion is print correct frequencys or make sure approach tells the correct frequency or tower needs to listen to both!

Title: INSTRUCTOR SAFETY PLT OF AN SMA SEL USED THE OLD WRONG TWR FREQ RESULTING IN ENTERING AN ATA WITHOUT CLRNC.

Narrative: ON MAY/SAT/94, APPROX XA30 LCL, 4 OF US FLYING ON AN INST FLT PLAN FROM MLB TO OUR DEST, ALBERT WHITTIED (SPG). WE WERE CRUISING AT AN ALT OF 6000 FT AS WE NEARED THE E SIDE OF THE TAMPA BAY AREA. TAMPA APCH CLRED US DOWN TO 3000 FT AND, SOON AFTER, WAS TRYING TO GET US UNDER THE CLOUD LAYER FOR A VISUAL APCH. WE WERE APPROX 5 MI AWAY FROM SPG AT 1600 FT FOR THE VISUAL TO RWY 36 WHEN APCH TOLD US TO CONTACT TWR (NO FREQ). I WAS WORKING RADIOS AND HAD ALREADY PUT IN STANDBY 120.4 (PUBLISHED TWR FREQ). WHEN I RPTED L BASE RWY 36, NOBODY REPLIED. AFTER 3 TIRES, I TOLD THE PIC I COULD NOT CONTACT TWR AND I FELT WE SHOULD CONTACT APCH AGAIN TO LET SOMEONE KNOW OF OUR SIT (NOW APPROX 3 MI E, 'NO CONTACT'). APCH QUICKLY SAID TWR CHANGED TO 124.4 AND TO CALL BACK, ASAP. WE DID AND REACHED THEM. THE TWR OPERATOR SAID WE HAD VIOLATED THEIR AIRSPACE AND CLRED US TO LAND -- BEING 'FINAL TFC' (VERY UNSAFE CONDITION). IN ALL CURRENT PUBLISHED CHARTS, FACILITY, DIRECTORY, AND APCH PLATES STATE THE INCORRECT FREQ, AND AS FAR AS OUR WX BRIEFINGS WE REMEMBER NO SUCH MENTION OF NOTAMS. MY SUGGESTION IS PRINT CORRECT FREQS OR MAKE SURE APCH TELLS THE CORRECT FREQ OR TWR NEEDS TO LISTEN TO BOTH!
