## Discrepancy

FLT#1303, BOS-PHX. (AIRCRAFT DECLARED AN EMERGENCY) ' SLATS FAILED PRIOR TO LANDING. ECL FAILED TO CORRECT THE FAILURE. DURING APPROACH WE DISCOVERED THE FLAPS EXTENDED NORMALLY BUT THE SLATS NEVER DEPLOYED. NORMAL LANDING WITH REF + 15; REF TASK BD500-A-K05-50-27-02AAA-310A-A FOR INSP. PERFORMED VISUAL INSP. OF SLAT ACTUATORS TORQUE LIMITERS ON LH WING AND RH WING. FOUND LH WING SLAT ACTUATOR TORQUE LIMITER TRIPPED. RESET MANUALLY & PERFORMED OPS CHECK OF FLAP AND SLAT SYS PER AMP BD500-A-J27-50-00-01AAA-320A-A. THE OPS CHECK IS GOOD. NO TRIPS WERE NOTED ON SLAT #3. A/C IS OKAY FOR CONTINUED SERVICE.
