Narrative:

I was conducting a line check on a qualified airbus captain. As per company procedure, I was off VHF #1 and on company frequency confirming our gate information and other data. When I came back on VHF #1 we were crossing runway 21R/3L. (Active runways were 27). Several mins later, I asked the captain when he had received crossing clearance. He stated that he never did. I showed him the printed ATIS and asked him if runway 21R/3L indicated closed. It did not. I asked him if he realized he crossed an active runway, he did not. So I stressed, 'taxi in -- unless specifically cleared to cross or cleared to the gate -- to cross an active runway, even if it is not presently in use, requires a clearance. Ground control never said a word. I don't think they even realized it.

Title: RWY INCURSION WHEN AN A320 PIC CROSSES AN ACTIVE RWY WITHOUT CLRNC WHILE THE CHK CAPT, ACTING FO, WAS ON COMPANY RADIO AT DTW, MI.

Narrative: I WAS CONDUCTING A LINE CHK ON A QUALIFIED AIRBUS CAPT. AS PER COMPANY PROC, I WAS OFF VHF #1 AND ON COMPANY FREQ CONFIRMING OUR GATE INFO AND OTHER DATA. WHEN I CAME BACK ON VHF #1 WE WERE XING RWY 21R/3L. (ACTIVE RWYS WERE 27). SEVERAL MINS LATER, I ASKED THE CAPT WHEN HE HAD RECEIVED XING CLRNC. HE STATED THAT HE NEVER DID. I SHOWED HIM THE PRINTED ATIS AND ASKED HIM IF RWY 21R/3L INDICATED CLOSED. IT DID NOT. I ASKED HIM IF HE REALIZED HE CROSSED AN ACTIVE RWY, HE DID NOT. SO I STRESSED, 'TAXI IN -- UNLESS SPECIFICALLY CLRED TO CROSS OR CLRED TO THE GATE -- TO CROSS AN ACTIVE RWY, EVEN IF IT IS NOT PRESENTLY IN USE, REQUIRES A CLRNC. GND CTL NEVER SAID A WORD. I DON'T THINK THEY EVEN REALIZED IT.
