## Discrepancy

WITH BLEEDS OFF, CREW WAS GETTING AIRFLOW INTO CABIN THAT SMELLED OF SMOKE.  CREW FOLLOWED PROCEDURES AND LANDED AT THE NEXT STATION, WHICH WAS THE CLOSEST.  IT WAS SUSPECTED THAT A FLOW CONTROL VALVE STUCK OPEN, THE ENVIRONMENTAL AIR DUCTING GOT HOT, WHICH CAUSED SMOKE.  REPLACED THE FLOW CONTROL VALVE, SYSTEM OPS CHECKED GOOD.  (M)
