Narrative:

After landing, we turned off runway 10 at 'east' intersection (left turn off) and proceeded southeast on 'O'. We contacted ground and were cleared to general aviation. I had studied the airport diagram prior to landing and while taxiing I mistook runway 04/22 for taxiway 'O'. We entered the runway (which was notamed closed for landing traffic only) at 'P' intersection. At that point, ground instructed us to proceed on up the runway and clear at 'C' (the next available intersection), and proceed to general aviation. As we cleared the runway, I noticed an military small transport holding in position for a runway 22 departure. While this was the first time in 27 yrs that this has happened to me, I know of several other cases where it has happened. Of course, I did not see any markings on the taxiway, or I wouldn't have entered the runway. I feel the cause was due to a strange field and being unfamiliar with where I was or where I was going, except by the airport diagram. I feel like most airports are adequately marked; however, some aren't and perhaps that was contributory to my not noticing the runway markings.

Original NASA ASRS Text

Title: CPR TWIN JET MISSED TURN ON TXWY INADVERTENTLY TRANSGRESSED ACTIVE RWY.

Narrative: AFTER LNDG, WE TURNED OFF RWY 10 AT 'E' INTXN (L TURN OFF) AND PROCEEDED SE ON 'O'. WE CONTACTED GND AND WERE CLRED TO GENERAL AVIATION. I HAD STUDIED THE ARPT DIAGRAM PRIOR TO LNDG AND WHILE TAXIING I MISTOOK RWY 04/22 FOR TXWY 'O'. WE ENTERED THE RWY (WHICH WAS NOTAMED CLOSED FOR LNDG TFC ONLY) AT 'P' INTXN. AT THAT POINT, GND INSTRUCTED US TO PROCEED ON UP THE RWY AND CLR AT 'C' (THE NEXT AVAILABLE INTXN), AND PROCEED TO GENERAL AVIATION. AS WE CLRED THE RWY, I NOTICED AN MIL SMT HOLDING IN POS FOR A RWY 22 DEP. WHILE THIS WAS THE FIRST TIME IN 27 YRS THAT THIS HAS HAPPENED TO ME, I KNOW OF SEVERAL OTHER CASES WHERE IT HAS HAPPENED. OF COURSE, I DID NOT SEE ANY MARKINGS ON THE TXWY, OR I WOULDN'T HAVE ENTERED THE RWY. I FEEL THE CAUSE WAS DUE TO A STRANGE FIELD AND BEING UNFAMILIAR WITH WHERE I WAS OR WHERE I WAS GOING, EXCEPT BY THE ARPT DIAGRAM. I FEEL LIKE MOST ARPTS ARE ADEQUATELY MARKED; HOWEVER, SOME AREN'T AND PERHAPS THAT WAS CONTRIBUTORY TO MY NOT NOTICING THE RWY MARKINGS.
