Narrative:

We approached salt lake municipal airport (salt lake #2), which is U42. As we approached U42 from the north, approach was working with us as we passed over slc international in the salt lake class B airspace. Nearing the southern edge of the airspace we were cleared for a visual approach to U42 and approach informed us we would be clear of the class B as we left 6000 ft MSL. As we passed through 500 ft, I canceled our IFR and we set up for a straight-in to runway 16 at U42. As we neared the airport another aircraft was departing 16, so we went overhead and entered the downwind to the west of U42. After some confusion as to whether we were at the right airport, we turned base and final for runway 16 and landed uneventfully. After landing, I looked at the IFR area chart closer, and realized that while the class B floor is 6000 ft MSL, over U42, it is down to the ground just to the north around slc international. We departed about 15 mins later and worked with salt lake approach again and they did not say a word. At the same time we were concerned that our approach may have brought us back into the salt lake class B airspace as we flew over base and final to runway 16. As best I can remember we flew about a 3 - 3 1/2 mi final. The area chart does not give any distance information on how far the class B airspace is to the north of U42. I think we were probably ok, but we had to have been close to re-entering the class B airspace. This could have been avoided if we had reviewed the area chart closer before approaching the airport.

Title: A FALCON 50 FLT CREW EXPERIENCES AN UNPLANNED RE-ENTRY INTO THE CLASS B AIRSPACE OF SLC, UT.

Narrative: WE APCHED SALT LAKE MUNICIPAL ARPT (SALT LAKE #2), WHICH IS U42. AS WE APCHED U42 FROM THE N, APCH WAS WORKING WITH US AS WE PASSED OVER SLC INTL IN THE SALT LAKE CLASS B AIRSPACE. NEARING THE SOUTHERN EDGE OF THE AIRSPACE WE WERE CLRED FOR A VISUAL APCH TO U42 AND APCH INFORMED US WE WOULD BE CLR OF THE CLASS B AS WE LEFT 6000 FT MSL. AS WE PASSED THROUGH 500 FT, I CANCELED OUR IFR AND WE SET UP FOR A STRAIGHT-IN TO RWY 16 AT U42. AS WE NEARED THE ARPT ANOTHER ACFT WAS DEPARTING 16, SO WE WENT OVERHEAD AND ENTERED THE DOWNWIND TO THE W OF U42. AFTER SOME CONFUSION AS TO WHETHER WE WERE AT THE RIGHT ARPT, WE TURNED BASE AND FINAL FOR RWY 16 AND LANDED UNEVENTFULLY. AFTER LNDG, I LOOKED AT THE IFR AREA CHART CLOSER, AND REALIZED THAT WHILE THE CLASS B FLOOR IS 6000 FT MSL, OVER U42, IT IS DOWN TO THE GND JUST TO THE N AROUND SLC INTL. WE DEPARTED ABOUT 15 MINS LATER AND WORKED WITH SALT LAKE APCH AGAIN AND THEY DID NOT SAY A WORD. AT THE SAME TIME WE WERE CONCERNED THAT OUR APCH MAY HAVE BROUGHT US BACK INTO THE SALT LAKE CLASS B AIRSPACE AS WE FLEW OVER BASE AND FINAL TO RWY 16. AS BEST I CAN REMEMBER WE FLEW ABOUT A 3 - 3 1/2 MI FINAL. THE AREA CHART DOES NOT GIVE ANY DISTANCE INFO ON HOW FAR THE CLASS B AIRSPACE IS TO THE N OF U42. I THINK WE WERE PROBABLY OK, BUT WE HAD TO HAVE BEEN CLOSE TO RE-ENTERING THE CLASS B AIRSPACE. THIS COULD HAVE BEEN AVOIDED IF WE HAD REVIEWED THE AREA CHART CLOSER BEFORE APCHING THE ARPT.
