Narrative:

Clear to taxi to runway 1 at mei. Possibly due to fatigue (6 leg day, 10+ hour duty period), I proceeded to runway 19. In the process, I crossed runway 4/22. Mei tower said it was not a problem and remainder of flight was uneventful. Perhaps shorter duty days or required breaks on lengthy duty days (since crew had no breaks this day) could prevent fatigue and pilot errors.

Narrative: CLR TO TAXI TO RWY 1 AT MEI. POSSIBLY DUE TO FATIGUE (6 LEG DAY, 10+ HR DUTY PERIOD), I PROCEEDED TO RWY 19. IN THE PROCESS, I CROSSED RWY 4/22. MEI TWR SAID IT WAS NOT A PROB AND REMAINDER OF FLT WAS UNEVENTFUL. PERHAPS SHORTER DUTY DAYS OR REQUIRED BREAKS ON LENGTHY DUTY DAYS (SINCE CREW HAD NO BREAKS THIS DAY) COULD PREVENT FATIGUE AND PLT ERRORS.
