Narrative:

About XA00 on may/sat/02 I landed on runway 17 at azo, mi. I exited the runway with a right turn onto runway 27 and then turned right up taxiway a, as instructed by the tower. I thought that we had been cleared to the gate and crossed runway 23 after clearing right and left. After crossing runway 23, ground instructed us to call the tower. The tower supervisor informed me that runway 23 had been active and an aircraft had been coming in for landing when we had crossed. He apologized that no one had tried to stop us until after we were crossing, but said the blame would be placed on me for lack of proper separation. I'm not sure why I thought we had been cleared to the gate. Contributing factors to this incident were an early show that morning and the resulting fatigue from getting only about 4 hours sleep. My first officer had also slept little the night before and had just returned recently from about a 6 month furlough. Later we also discovered that his headset was broken and at times cut out and caused static. At the time of the incident the tower was very busy with student pilot traffic. Supplemental information from acn 547589: captain thought we were cleared to the ramp. We never received a hold short instruction so we crossed runway 5/23. Bad crew communication.

Title: AN LTT CREW, AFTER LNDG AT AZO, CROSSED AN ACTIVE RWY WITHOUT A CLRNC.

Narrative: ABOUT XA00 ON MAY/SAT/02 I LANDED ON RWY 17 AT AZO, MI. I EXITED THE RWY WITH A R TURN ONTO RWY 27 AND THEN TURNED R UP TXWY A, AS INSTRUCTED BY THE TWR. I THOUGHT THAT WE HAD BEEN CLRED TO THE GATE AND CROSSED RWY 23 AFTER CLRING R AND L. AFTER XING RWY 23, GND INSTRUCTED US TO CALL THE TWR. THE TWR SUPVR INFORMED ME THAT RWY 23 HAD BEEN ACTIVE AND AN ACFT HAD BEEN COMING IN FOR LNDG WHEN WE HAD CROSSED. HE APOLOGIZED THAT NO ONE HAD TRIED TO STOP US UNTIL AFTER WE WERE XING, BUT SAID THE BLAME WOULD BE PLACED ON ME FOR LACK OF PROPER SEPARATION. I'M NOT SURE WHY I THOUGHT WE HAD BEEN CLRED TO THE GATE. CONTRIBUTING FACTORS TO THIS INCIDENT WERE AN EARLY SHOW THAT MORNING AND THE RESULTING FATIGUE FROM GETTING ONLY ABOUT 4 HRS SLEEP. MY FO HAD ALSO SLEPT LITTLE THE NIGHT BEFORE AND HAD JUST RETURNED RECENTLY FROM ABOUT A 6 MONTH FURLOUGH. LATER WE ALSO DISCOVERED THAT HIS HEADSET WAS BROKEN AND AT TIMES CUT OUT AND CAUSED STATIC. AT THE TIME OF THE INCIDENT THE TWR WAS VERY BUSY WITH STUDENT PLT TFC. SUPPLEMENTAL INFO FROM ACN 547589: CAPT THOUGHT WE WERE CLRED TO THE RAMP.
