Narrative:

Just prior to approach, flight director became erratic and therefore, autoplt became unusable. During efforts to set up for the approach while hand flying the airplane, including descent, incorrectly set the HSI course indicator to 10 degrees instead of 100 degrees. Therefore, I made left turns to intercept localizer twice instead of to the right as was correct. Thus, I had to be vectored around twice for re-intercept. Landed without incident. This problem could have been avoided if I had rechked the HSI course indicator as is my usual procedure. I should not have let the extra workload of an erratic primary NAVAID distract me from normal procedures.

Title: PVT PLT OF A BEECH BARON BE58P (BE58) FLEW THROUGH THE FINAL LOC COURSE TWICE DUE TO INCORRECTLY SETTING THE HSI COURSE INDICATOR FOR THE WRONG COURSE.

Narrative: JUST PRIOR TO APCH, FLT DIRECTOR BECAME ERRATIC AND THEREFORE, AUTOPLT BECAME UNUSABLE. DURING EFFORTS TO SET UP FOR THE APCH WHILE HAND FLYING THE AIRPLANE, INCLUDING DSCNT, INCORRECTLY SET THE HSI COURSE INDICATOR TO 10 DEGS INSTEAD OF 100 DEGS. THEREFORE, I MADE L TURNS TO INTERCEPT LOC TWICE INSTEAD OF TO THE R AS WAS CORRECT. THUS, I HAD TO BE VECTORED AROUND TWICE FOR RE-INTERCEPT. LANDED WITHOUT INCIDENT. THIS PROB COULD HAVE BEEN AVOIDED IF I HAD RECHKED THE HSI COURSE INDICATOR AS IS MY USUAL PROC. I SHOULD NOT HAVE LET THE EXTRA WORKLOAD OF AN ERRATIC PRIMARY NAVAID DISTRACT ME FROM NORMAL PROCS.
