Narrative:
The copilot and I were both in the cockpit when the clearance was given and read back which assigned us the salt lake 3 departure. Both of us read the SID (attached) and agreed on the procedure we thought was correct. Since we were to depart on 34R, the procedure we thought was correct was to fly heading 340 to 7000 ft, then turn left to slc VOR, maintain 8000 ft, then expect vectors to assigned route. The altitude we were assigned in the clearance was 8000 ft, which agreed with that portion of our interpretation of the SID. We taxied out and executed a normal takeoff, then were instructed to contact departure. Departure control told us to maintain 8000 ft, and since that was all he told us, we concurred that we were to continue the SID. As we were climbing through about 6500, departure told us to maintain (I think) 16000. Upon reaching 7000, I started a left turn to the VOR. As I was passing through a heading of about 270 departure called us and asked what heading we were turning to. The copilot told him we were turning direct to the VOR. The controller came back and told us to turn immediately to 360. At this point I was in a 30 degree bank, at 250 KTS, climbing through about 8500, with a climb rate of 4000 to 5000 FPM. I immediately rolled the aircraft out of the left turn and rolled into a 30 degree right bank. The controller came back and told us to continue heading to 040 with a good rate of turn. The copilot acknowledged, then the controller told us to maintain 10000. At this point we were climbing through 9700 or 9800, so I jerked the power to idle and rolled the airplane into a 60 degree bank to attempt to comply. We ballooned to 10200 or 10300 and leveled at 10000. The controller asked us what procedure we were following and we replied that we were following the SID. He did not comment on that or explain the proper procedures, instead simply gave us a new altitude and handed us off to center. The rest of the flight continued normally.

Title: FLC OF SMT JET MISREAD DEP SID FROM SLC. DEP CTLR VECTORED THEM TO PROPER DEP.
Narrative: THE COPLT AND I WERE BOTH IN THE COCKPIT WHEN THE CLRNC WAS GIVEN AND READ BACK WHICH ASSIGNED US THE SALT LAKE 3 DEP. BOTH OF US READ THE SID (ATTACHED) AND AGREED ON THE PROC WE THOUGHT WAS CORRECT. SINCE WE WERE TO DEPART ON 34R, THE PROC WE THOUGHT WAS CORRECT WAS TO FLY HDG 340 TO 7000 FT, THEN TURN L TO SLC VOR, MAINTAIN 8000 FT, THEN EXPECT VECTORS TO ASSIGNED RTE. THE ALT WE WERE ASSIGNED IN THE CLRNC WAS 8000 FT, WHICH AGREED WITH THAT PORTION OF OUR INTERPRETATION OF THE SID. WE TAXIED OUT AND EXECUTED A NORMAL TKOF, THEN WERE INSTRUCTED TO CONTACT DEP. DEP CTL TOLD US TO MAINTAIN 8000 FT, AND SINCE THAT WAS ALL HE TOLD US, WE CONCURRED THAT WE WERE TO CONTINUE THE SID. AS WE WERE CLBING THROUGH ABOUT 6500, DEP TOLD US TO MAINTAIN (I THINK) 16000. UPON REACHING 7000, I STARTED A L TURN TO THE VOR. AS I WAS PASSING THROUGH A HDG OF ABOUT 270 DEP CALLED US AND ASKED WHAT HDG WE WERE TURNING TO. THE COPLT TOLD HIM WE WERE TURNING DIRECT TO THE VOR. THE CTLR CAME BACK AND TOLD US TO TURN IMMEDIATELY TO 360. AT THIS POINT I WAS IN A 30 DEG BANK, AT 250 KTS, CLBING THROUGH ABOUT 8500, WITH A CLB RATE OF 4000 TO 5000 FPM. I IMMEDIATELY ROLLED THE ACFT OUT OF THE L TURN AND ROLLED INTO A 30 DEG R BANK. THE CTLR CAME BACK AND TOLD US TO CONTINUE HDG TO 040 WITH A GOOD RATE OF TURN. THE COPLT ACKNOWLEDGED, THEN THE CTLR TOLD US TO MAINTAIN 10000. AT THIS POINT WE WERE CLBING THROUGH 9700 OR 9800, SO I JERKED THE PWR TO IDLE AND ROLLED THE AIRPLANE INTO A 60 DEG BANK TO ATTEMPT TO COMPLY. WE BALLOONED TO 10200 OR 10300 AND LEVELED AT 10000. THE CTLR ASKED US WHAT PROC WE WERE FOLLOWING AND WE REPLIED THAT WE WERE FOLLOWING THE SID. HE DID NOT COMMENT ON THAT OR EXPLAIN THE PROPER PROCS, INSTEAD SIMPLY GAVE US A NEW ALT AND HANDED US OFF TO CENTER. THE REST OF THE FLT CONTINUED NORMALLY.
