Narrative:

Departed C09 for a local training flight to 1c5. Prior to departure; called ikk FSS for a brief. Described to briefer an XA00 local time departure for a VFR flight to 1c5. I was given a standard brief and NOTAMS for C09 and 1c5. En route to 1c5; I decided to do a landing at lot. I announced my intentions on lot's unicom; 122.8; from 6 miles southeast of the field and continued inbound. I made position calls on 122.8 as I entered the pattern; turned downwind; turned base and again on final. After touchdown; I noticed green flashing lights from a building north of runway 9/27. After turning off the runway I figured out there was a temporary tower in operation; next I listened to the AWOS frequency 118.525; and found the information for tower ground frequencys. Once on the ground frequency I apologized for landing without contacting the temporary tower and was given clearance to depart runway 27. I also used a flight planner prior to my flight to look for tfr's and did not see this temporary airspace. My corrective action for future flts will be to ask for NOTAMS at all airports surrounding my destination during the flight brief. With that said I also believe flight service should have informed me of the temporary tower during my brief. I clearly asked for a brief for C09 to 1c5. This route of flight could easily get me into the temporary class D airspace at lot. The briefer did inform me of some activity to avoid near gary; indiana; and that is much further from 1c5 than lot. I also do not understand why the temporary tower did not answer my position calls on the CTAF 122.8 and inform me of the temporary class D. They were monitoring the frequency and I did make my first position call at a point where I was clear of the class D airspace.

Title: A DA20 PILOT ENTERED AND LANDED IN THE TEMPORARY CLASS D LOT TOWER AREA WITHOUT CLEARANCE; AT LEAST PARTLY BECAUSE OF AN INCOMPLETE BRIEFING FROM FSS.

Narrative: DEPARTED C09 FOR A LOCAL TRAINING FLT TO 1C5. PRIOR TO DEP; CALLED IKK FSS FOR A BRIEF. DESCRIBED TO BRIEFER AN XA00 LOCAL TIME DEP FOR A VFR FLT TO 1C5. I WAS GIVEN A STANDARD BRIEF AND NOTAMS FOR C09 AND 1C5. ENRTE TO 1C5; I DECIDED TO DO A LNDG AT LOT. I ANNOUNCED MY INTENTIONS ON LOT'S UNICOM; 122.8; FROM 6 MILES SE OF THE FIELD AND CONTINUED INBOUND. I MADE POSITION CALLS ON 122.8 AS I ENTERED THE PATTERN; TURNED DOWNWIND; TURNED BASE AND AGAIN ON FINAL. AFTER TOUCHDOWN; I NOTICED GREEN FLASHING LIGHTS FROM A BUILDING N OF RWY 9/27. AFTER TURNING OFF THE RWY I FIGURED OUT THERE WAS A TEMPORARY TWR IN OPERATION; NEXT I LISTENED TO THE AWOS FREQ 118.525; AND FOUND THE INFO FOR TWR GND FREQS. ONCE ON THE GND FREQ I APOLOGIZED FOR LNDG WITHOUT CONTACTING THE TEMPORARY TWR AND WAS GIVEN CLRNC TO DEPART RWY 27. I ALSO USED A FLT PLANNER PRIOR TO MY FLT TO LOOK FOR TFR'S AND DID NOT SEE THIS TEMPORARY AIRSPACE. MY CORRECTIVE ACTION FOR FUTURE FLTS WILL BE TO ASK FOR NOTAMS AT ALL ARPTS SURROUNDING MY DEST DURING THE FLT BRIEF. WITH THAT SAID I ALSO BELIEVE FLT SVC SHOULD HAVE INFORMED ME OF THE TEMPORARY TWR DURING MY BRIEF. I CLEARLY ASKED FOR A BRIEF FOR C09 TO 1C5. THIS RTE OF FLT COULD EASILY GET ME INTO THE TEMPORARY CLASS D AIRSPACE AT LOT. THE BRIEFER DID INFORM ME OF SOME ACTIVITY TO AVOID NEAR GARY; INDIANA; AND THAT IS MUCH FURTHER FROM 1C5 THAN LOT. I ALSO DO NOT UNDERSTAND WHY THE TEMPORARY TWR DID NOT ANSWER MY POSITION CALLS ON THE CTAF 122.8 AND INFORM ME OF THE TEMPORARY CLASS D. THEY WERE MONITORING THE FREQ AND I DID MAKE MY FIRST POSITION CALL AT A POINT WHERE I WAS CLEAR OF THE CLASS D AIRSPACE.
