## Discrepancy

DURING TRANSIT CHECK, FIRE ALARMS IN BOTH ENGINES DID NOT OPERATE AND ONLY LIGHTS TURNED ON.  DURING REVISION DETECTED FIRE WARNING AURAL SWITCH OPERATED CORRECTLY.

AIRCRAFT SENT TO HANGAR, PT7 & PT2 LEAK CHECK PERFORMED, PRBC LINES TIGHTENED, ACCELERATION CHAMBER AND ANTI SURGE VALVES WERE LUBRICATED, RUDDER PT2 UNION REPLACED AND REMOTE CONTROL TRIM PERFORMED, TESTED CORRECT.
