Narrative:

On sep/xa/98, I was on an IFR flight from san antonio, tx, to harlingen, tx. I was vectored to the ILS final approach course and performed an ILS. Conditions at the time were VMC and I was cleared to announce my position on the CTAF. (Tower was closed.) I landed safely and taxied in. What I forgot to do, however, was close my IFR flight plan with approach. Apparently they closed the airport for an unspecified amount of time. I discovered my mistake when a friend of mine called me at home later in the morning. I attribute this incident to fatigue. My work schedule requires an XA00 departure, and I guess I was tired. To prevent this from happening again, I will add this to my after landing checklist.

CONDITIONS AT THE TIME WERE VMC AND I WAS CLRED TO ANNOUNCE MY POS ON THE CTAF. (TWR WAS CLOSED.) I LANDED SAFELY AND TAXIED IN. WHAT I FORGOT TO DO, HOWEVER, WAS CLOSE MY IFR FLT PLAN WITH APCH.
