Narrative:

Took off from salt lake municipal #2 to the south and requested to transit salt lake class B to the north to logan. Was told to squawk discrete code and turn east to pick up highway, then head north along highway. Handed off to second controller. Controller advised to maintain at or below 8500. After passing abeam salt lake international we turned toward northwest to pass west of hill AFB. Controller asked for heading then said he had told us to stay east of hill AFB. We turned to pass east of hill AFB then exited the class B airspace. Two things contributed to this event. The first was that I was checking out a pilot in his newly acquired mooney and the radio intercom had a tremendous amount of static. I simply did not hear the instruction to stay east of hill AFB. The second item was that after the controller advised us to resume normal navigation we turned northwest to follow the shoreline west of hill AFB since the personnel at the municipal airport indicated that this was a good way to remain clear of the airspace at hill AFB. In retrospect, it was not a good idea to take the student into such busy airspace when the radio intercom combination was not working correctly and was full of static. A contributing factor was that we had briefed our flight route on the ground before takeoff and were expecting to fly west of hill AFB.

Original NASA ASRS Text

Title: MOONEY ACFT TRANSITING CLASS 'B' AIRSPACE WAS INSTRUCTED BY ATC TO REMAIN E OF HILL AFB. RPTR ISTR DIDN'T HEAR THOSE INSTRUCTIONS, OSTENSIBLY DUE TO RADIO STATIC, AND ERRONEOUSLY ENTERED CLASS 'D' AIRSPACE.

Narrative: TOOK OFF FROM SALT LAKE MUNICIPAL #2 TO THE S AND REQUESTED TO TRANSIT SALT LAKE CLASS B TO THE N TO LOGAN. WAS TOLD TO SQUAWK DISCRETE CODE AND TURN E TO PICK UP HIGHWAY, THEN HEAD N ALONG HIGHWAY. HANDED OFF TO SECOND CTLR. CTLR ADVISED TO MAINTAIN AT OR BELOW 8500. AFTER PASSING ABEAM SALT LAKE INTERNATIONAL WE TURNED TOWARD NW TO PASS W OF HILL AFB. CTLR ASKED FOR HEADING THEN SAID HE HAD TOLD US TO STAY E OF HILL AFB. WE TURNED TO PASS E OF HILL AFB THEN EXITED THE CLASS B AIRSPACE. TWO THINGS CONTRIBUTED TO THIS EVENT. THE FIRST WAS THAT I WAS CHECKING OUT A PLT IN HIS NEWLY ACQUIRED MOONEY AND THE RADIO INTERCOM HAD A TREMENDOUS AMOUNT OF STATIC. I SIMPLY DID NOT HEAR THE INSTRUCTION TO STAY E OF HILL AFB. THE SECOND ITEM WAS THAT AFTER THE CTLR ADVISED US TO RESUME NORMAL NAVIGATION WE TURNED NW TO FOLLOW THE SHORELINE W OF HILL AFB SINCE THE PERSONNEL AT THE MUNICIPAL AIRPORT INDICATED THAT THIS WAS A GOOD WAY TO REMAIN CLR OF THE AIRSPACE AT HILL AFB. IN RETROSPECT, IT WAS NOT A GOOD IDEA TO TAKE THE STUDENT INTO SUCH BUSY AIRSPACE WHEN THE RADIO INTERCOM COMBINATION WAS NOT WORKING CORRECTLY AND WAS FULL OF STATIC. A CONTRIBUTING FACTOR WAS THAT WE HAD BRIEFED OUR FLT ROUTE ON THE GND BEFORE TKOF AND WERE EXPECTING TO FLY W OF HILL AFB.

Mooney aircraft transiting class 'B' airspace was instructed by ATC to remain east of hill AFB. Reporter instructor didn't hear those instructions, ostensibly due to radio static, and erroneously entered class 'D' airspace.
