MLG IS DISCOVERED TO HAVE FOD FROM BLUE ICE. NOT CERTAIN WHERE IT OCCURRED.

Narrative

AFTER LEG 1 (LNDG AT SMF) I NOTICED A BLUE WATER LEAK AND ICE BEHIND THE PANEL OF THE FORWARD LAVATORY SVC PANEL. A MECH WAS WITH ME. HE SAID IT WAS FROM THE INPUT LINE AND WAS VERY SMALL. HE REPLACED THE INPUT LINE CAP; ALTHOUGH THE LEAK APPEARED TO HAVE STOPPED EVEN BEFORE THE NEW CAP WAS PUT ON. SINCE THE ENG RAN WELL THROUGHOUT THE FLT; I DIDN'T THINK ABOUT HAVING THE MECH CHK THE ENG. HE ALSO DIDN'T THINK ABOUT THE ENG AND POTENTIAL FOR BLUE ICE FOD. NOTHING WAS ENTERED IN THE ACFT LOG. LEG 2 WAS UNEVENTFUL. AT THE COMPLETION OF LEG 2 I TOLD THE MECH RECEIVING THE FLT WHAT HAD TRANSPIRED AT SMF. I DON'T KNOW IF HE CHKED THE ENG OR NOT. IT DID RUN WELL ON LEG 2. THE MECH DRAINED THE FORWARD LAVATORY; BLOCKED IT OFF; AND MADE APPROPRIATE LOGBOOK ENTRY. LEG 3 WAS UNEVENTFUL; AND THE ENGS RAN WELL. BUT; DAMAGE TO THE #1 FAN WAS DISCOVERED DURING THE OVERNIGHT INSPECTION. MAYBE THE DAMAGE WAS DONE ON LEG 3; AND MAYBE IT WAS DONE ON LEG 1 OR 2. I DON'T KNOW. I DO THINK MY JUDGEMENT WAS FLAWED BECAUSE I DIDN'T ORDER A MECH TO INSPECT THE HARD TO ACCESS #1 ENG; AFTER THE FIRST OR SECOND LEG.
