Narrative:
On a flight from lga to jac, we had descended to 14000 ft approaching the dnw VOR. We were asked which approach we would like, and said the ILS to runway 18. We were VFR at the time and being the first time for me into jac, I thought we would use the localizer to line us up with the runway. Shortly before reaching the dnw VOR, we were cleared to the approach to ILS runway 18 via the dnw transition. Around that time, xmissions were becoming intermittent. After passing dnw VOR, we intercepted the 267 degree radial and descended to 12000 ft. Shortly after that, we acquired the airport and intercepted the localizer inbound. After intercepting the localizer inbound, ZLC came up and said, for your information we were supposed to do the procedure turn. At that time we canceled the IFR and continued in visually. Nothing else was said. The peculiar thing about this was this approach was featured in the april issue of pro pilot magazine. And it goes to show you, if you do not do full procedure ILS approachs all the time, and you are used to being vectored for approachs, and you see the field, the tendency is to turn for the field. I also feel there was a breakdown of CRM due to the confusion over the transition which was assigned with the approach clearance.

Title: FLC OF G3 CPR ACFT FAIL TO INCLUDE THE PROC TURN IN THEIR ILS APCH. SIGHTING THE RWY THEY TURN DIRECTLY TOWARD IT.
Narrative: ON A FLT FROM LGA TO JAC, WE HAD DSNDED TO 14000 FT APCHING THE DNW VOR. WE WERE ASKED WHICH APCH WE WOULD LIKE, AND SAID THE ILS TO RWY 18. WE WERE VFR AT THE TIME AND BEING THE FIRST TIME FOR ME INTO JAC, I THOUGHT WE WOULD USE THE LOC TO LINE US UP WITH THE RWY. SHORTLY BEFORE REACHING THE DNW VOR, WE WERE CLRED TO THE APCH TO ILS RWY 18 VIA THE DNW TRANSITION. AROUND THAT TIME, XMISSIONS WERE BECOMING INTERMITTENT. AFTER PASSING DNW VOR, WE INTERCEPTED THE 267 DEG RADIAL AND DSNDED TO 12000 FT. SHORTLY AFTER THAT, WE ACQUIRED THE ARPT AND INTERCEPTED THE LOC INBOUND. AFTER INTERCEPTING THE LOC INBOUND, ZLC CAME UP AND SAID, FOR YOUR INFO WE WERE SUPPOSED TO DO THE PROC TURN. AT THAT TIME WE CANCELED THE IFR AND CONTINUED IN VISUALLY. NOTHING ELSE WAS SAID. THE PECULIAR THING ABOUT THIS WAS THIS APCH WAS FEATURED IN THE APRIL ISSUE OF PRO PLT MAGAZINE. AND IT GOES TO SHOW YOU, IF YOU DO NOT DO FULL PROC ILS APCHS ALL THE TIME, AND YOU ARE USED TO BEING VECTORED FOR APCHS, AND YOU SEE THE FIELD, THE TENDENCY IS TO TURN FOR THE FIELD. I ALSO FEEL THERE WAS A BREAKDOWN OF CRM DUE TO THE CONFUSION OVER THE TRANSITION WHICH WAS ASSIGNED WITH THE APCH CLRNC.
