Narrative:

I was on a visual descent into mhk from the southwest. I noted restr airspace to the west of the airport on the en route chart, but did not feel it would conflict with my visual approach into the airport. Approximately 2-3 mi southwest of the airport, I reported that I was on a right downwind for runway 21. I was less than 1 mi west of the extended centerline, tracking parallel to the runway. At this time, tower informed me I was in restr airspace and should turn right immediately. I complied with the instructions and continued with left traffic to landing. Once on the ground, I had the opportunity to review a sectional of the area (an area I am not familiar with). The class D airspace surrounding the airport is severely limited to the west by the restr airspace. This was not as apparent on the en route chart. Had I had a sectional for review prior to the approach, I would have accomplished my visual approach from the southwest around to the southeast. A proper and thorough review of the surrounding airspace and landmarks prior to the approach would have prevented this incursion. Factors contributing to this incursion include: severe clear, resulting in a lax briefing of the approach and surrounding airspace, reliance on data that was not the best source of information, less than full examination of the information that was available, running behind schedule and in a hurry. Although proper inspection of available information would have prevented this incursion, a reminder by ATC at the initiation of the visual would have been helpful, given the extreme closeness of the restr area to the airport.

Title: A C182 CFI ENTERS THE R3602B SECTOR OF FORT RILEY WHEN MAKING A VISUAL APCH, R DOWNWIND TO MHK, KS.

Narrative: I WAS ON A VISUAL DSCNT INTO MHK FROM THE SW. I NOTED RESTR AIRSPACE TO THE W OF THE ARPT ON THE ENRTE CHART, BUT DID NOT FEEL IT WOULD CONFLICT WITH MY VISUAL APCH INTO THE ARPT. APPROX 2-3 MI SW OF THE ARPT, I RPTED THAT I WAS ON A R DOWNWIND FOR RWY 21. I WAS LESS THAN 1 MI W OF THE EXTENDED CTRLINE, TRACKING PARALLEL TO THE RWY. AT THIS TIME, TWR INFORMED ME I WAS IN RESTR AIRSPACE AND SHOULD TURN R IMMEDIATELY. I COMPLIED WITH THE INSTRUCTIONS AND CONTINUED WITH L TFC TO LNDG. ONCE ON THE GND, I HAD THE OPPORTUNITY TO REVIEW A SECTIONAL OF THE AREA (AN AREA I AM NOT FAMILIAR WITH). THE CLASS D AIRSPACE SURROUNDING THE ARPT IS SEVERELY LIMITED TO THE W BY THE RESTR AIRSPACE. THIS WAS NOT AS APPARENT ON THE ENRTE CHART. HAD I HAD A SECTIONAL FOR REVIEW PRIOR TO THE APCH, I WOULD HAVE ACCOMPLISHED MY VISUAL APCH FROM THE SW AROUND TO THE SE. A PROPER AND THOROUGH REVIEW OF THE SURROUNDING AIRSPACE AND LANDMARKS PRIOR TO THE APCH WOULD HAVE PREVENTED THIS INCURSION. FACTORS CONTRIBUTING TO THIS INCURSION INCLUDE: SEVERE CLR, RESULTING IN A LAX BRIEFING OF THE APCH AND SURROUNDING AIRSPACE, RELIANCE ON DATA THAT WAS NOT THE BEST SOURCE OF INFO, LESS THAN FULL EXAMINATION OF THE INFO THAT WAS AVAILABLE, RUNNING BEHIND SCHEDULE AND IN A HURRY. ALTHOUGH PROPER INSPECTION OF AVAILABLE INFO WOULD HAVE PREVENTED THIS INCURSION, A REMINDER BY ATC AT THE INITIATION OF THE VISUAL WOULD HAVE BEEN HELPFUL, GIVEN THE EXTREME CLOSENESS OF THE RESTR AREA TO THE ARPT.
