Narrative:
On approach (ILS runway 32) into pln close to minimums, I noticed just as I broke out of the overcast the localizer deflected to the right after being stable for the entire approach. I saw the runway nearly at the same time, also to the right. I maneuvered and made a safe landing within the first third of the runway. I also noticed an aircraft waiting to take off at the 'hold short' lines. I wondered if his aircraft possibly blocked or disrupted the ILS. In hindsight, I should have abandoned the approach and gone missed.

Title: A BE58 PLT NOTICES THE CDI NEEDLE DEFLECT TO THE R JUST AS HE BREAKS OUT OF A LOW OVCST LAYER ON AN APCH INTO PLN.
Narrative: ON APCH (ILS RWY 32) INTO PLN CLOSE TO MINIMUMS, I NOTICED JUST AS I BROKE OUT OF THE OVCST THE LOC DEFLECTED TO THE R AFTER BEING STABLE FOR THE ENTIRE APCH. I SAW THE RWY NEARLY AT THE SAME TIME, ALSO TO THE R. I MANEUVERED AND MADE A SAFE LNDG WITHIN THE FIRST THIRD OF THE RWY. I ALSO NOTICED AN ACFT WAITING TO TAKE OFF AT THE 'HOLD SHORT' LINES. I WONDERED IF HIS ACFT POSSIBLY BLOCKED OR DISRUPTED THE ILS. IN HINDSIGHT, I SHOULD HAVE ABANDONED THE APCH AND GONE MISSED.
