## Discrepancy

THE PILOT HAD HAD “DUCT 1 OVERHEAT” MESSAGE, THEY SELECTED THE AIR SOURCE FROM BOTH TO #2 THEN SHORTY AFTER GOT A “DUCT 2 OVERHEAT”. WE HAD A A TECHNICIAN DISPATCHED FROM WEST STAR AVIATION WORK THE ISSUE AND DURING TROUBLESHOOTING FOUND THE RAM AIR DOOR CRACKED BLOCKING AIRFLOW. DEFECTIVE PART IS BEING REPLACED BY WEST STAR IN ABQ. PHOTOS AVAILABLE IF NEEDED.
