## Discrepancy

THE CREW REPORTED THAT DURING THE POST FLIGHT CHECKS, THE STALL CHANNEL 1 AND 2 WILL NOT IDENT. TROUBLESHOOTING IDENTIFIED THE F3 FUSE AS BEING OPEN BECAUSE OF HIGH RESISTANCE IN THE RT AIRFLOW SENSOR PN 1703-12, SN 1569. THE AIRFLOW SENSOR AND THE FUSE WERE REPLACED. FUNCTIONAL CHECKS WERE SATISFACTORY.
