Narrative:

I was on a VFR flight from ft wayne to independence, mo, with a planned fuel stop along the way. As I was approaching the quincy area, the WX started to deteriorate, so I decided to stop at quincy (uin). I called the unicom and was given winds and runway and proceeded to land. After I was on the ground, a departing aircraft informed me that I had landed at an airport with a control zone below VFR minimums. After looking at the sectional chart again, I realized this. In retrospect, I didn't expect to see a control zone at an uncontrolled airport and so I didn't notice it on the chart. I am much the wiser now.

Title: SMA LANDS AT UNCTLED ARPT NOT REALIZING AN ACTIVE CTL ZONE EXISTS THERE.

Narrative: I WAS ON A VFR FLT FROM FT WAYNE TO INDEPENDENCE, MO, WITH A PLANNED FUEL STOP ALONG THE WAY. AS I WAS APCHING THE QUINCY AREA, THE WX STARTED TO DETERIORATE, SO I DECIDED TO STOP AT QUINCY (UIN). I CALLED THE UNICOM AND WAS GIVEN WINDS AND RWY AND PROCEEDED TO LAND. AFTER I WAS ON THE GND, A DEPARTING ACFT INFORMED ME THAT I HAD LANDED AT AN ARPT WITH A CTL ZONE BELOW VFR MINIMUMS. AFTER LOOKING AT THE SECTIONAL CHART AGAIN, I REALIZED THIS. IN RETROSPECT, I DIDN'T EXPECT TO SEE A CTL ZONE AT AN UNCTLED ARPT AND SO I DIDN'T NOTICE IT ON THE CHART. I AM MUCH THE WISER NOW.
