Narrative:

During the approach phase, we were being vectored for an ILS approach to runway 32. We advised ATC that the prevailing wind was too strong for landing on runway 32. We were then cleared for an ILS to runway 32, with a circle to land to runway 14. The circling maneuver did not specify a direction, so during the approach briefing, we decided on a l-hand circle. About 4 mi from the airport, we became visual and was cleared for a visual approach to runway 14. Because of the prior briefing, I decided to continue on a left pattern, and joined on a left downwind, and eventual landing. After landing, I realized that the traffic pattern to runway 14 should have been to the right, not to the left. Factors that contributed to this were, a quick descent, thunderstorms in the vicinity, not examining the airport diagram in more detail, a last min switch from an instrument procedure to a visual procedure.

Original NASA ASRS Text

Title: FLC OF AN LTT JET USED THE WRONG TFC PATTERN FOR A VISUAL CIRCLE TO LAND OUT OF AN ILS APCH DUE TO NO ATC INSTRUCTIONS FOR WHICH WAY TO MAKE THE TURN, AND A LACK OF REVIEWING THE ARPT CHART.

Narrative: DURING THE APCH PHASE, WE WERE BEING VECTORED FOR AN ILS APCH TO RWY 32. WE ADVISED ATC THAT THE PREVAILING WIND WAS TOO STRONG FOR LNDG ON RWY 32. WE WERE THEN CLRED FOR AN ILS TO RWY 32, WITH A CIRCLE TO LAND TO RWY 14. THE CIRCLING MANEUVER DID NOT SPECIFY A DIRECTION, SO DURING THE APCH BRIEFING, WE DECIDED ON A L-HAND CIRCLE. ABOUT 4 MI FROM THE ARPT, WE BECAME VISUAL AND WAS CLRED FOR A VISUAL APCH TO RWY 14. BECAUSE OF THE PRIOR BRIEFING, I DECIDED TO CONTINUE ON A L PATTERN, AND JOINED ON A L DOWNWIND, AND EVENTUAL LNDG. AFTER LNDG, I REALIZED THAT THE TFC PATTERN TO RWY 14 SHOULD HAVE BEEN TO THE R, NOT TO THE L. FACTORS THAT CONTRIBUTED TO THIS WERE, A QUICK DSCNT, TSTMS IN THE VICINITY, NOT EXAMINING THE ARPT DIAGRAM IN MORE DETAIL, A LAST MIN SWITCH FROM AN INST PROC TO A VISUAL PROC.
