## Discrepancy

AIRCRAFT RETURNED TO PLATFORM DUE TO SMOKE IN THE CABIN. MAINTENANCE DETECTED A SHORT CIRCUIT IN THE LT ENGINE SYS (A) IGNITION SWITCH, SO BREAKERS K-26 AND L26 WERE PULLED OUT AND AC WAS SENT TO THE HANGAR. AT HANGAR, SWITCH S1-35 WAS DETECTED BURNED SO IT WAS REPLACED IAW MM 74-30-02, TESTED CORRECT.
