Narrative:

I was assigned to work aircraft X and was instructed by my lead to address a particular log page with respect to moisture which had been under the floor board of the east&east compartment. Upon inspecting the area; I discovered 3 insulation blankets which were quite soaked. I removed the blankets and determined that they were not unusable; so I fabricated brand new ones using the old ones as templates. I dried the area thoroughly underneath the wet blankets I found. After fabricating the new blankets; I checked them for fit and installed them in their respective places. Another mechanic on shift reinstalled the floor board and I signed off the log page thinking that I had fixed the problem. The aircraft was scheduled for revenue flight and I worked through my break to get the problem resolved. Little did I know; there was a conditional inspection required after a galley leak of any kind according to maintenance manual. I did not perform the conditional inspection. Furthermore; I didn't make mention in the corrective action block that I had actually dried out the area beneath the wet blankets by removing any moisture (which I had accomplished). I honestly knew nothing of a conditional inspection.

Title: AFTER DRYING THE AREA AND INSTALLING NEW INSULATION BLANKETS IN THE LOWER BELLY OF THE E&E COMPARTMENT; MECHANIC IS INFORMED THAT A CONDITIONAL INSPECTION IS REQUIRED FOR THAT AREA OF THE LOWER E&E COMPARTMENT.

Narrative: I WAS ASSIGNED TO WORK ACFT X AND WAS INSTRUCTED BY MY LEAD TO ADDRESS A PARTICULAR LOG PAGE WITH RESPECT TO MOISTURE WHICH HAD BEEN UNDER THE FLOOR BOARD OF THE E&E COMPARTMENT. UPON INSPECTING THE AREA; I DISCOVERED 3 INSULATION BLANKETS WHICH WERE QUITE SOAKED. I REMOVED THE BLANKETS AND DETERMINED THAT THEY WERE NOT UNUSABLE; SO I FABRICATED BRAND NEW ONES USING THE OLD ONES AS TEMPLATES. I DRIED THE AREA THOROUGHLY UNDERNEATH THE WET BLANKETS I FOUND. AFTER FABRICATING THE NEW BLANKETS; I CHKED THEM FOR FIT AND INSTALLED THEM IN THEIR RESPECTIVE PLACES. ANOTHER MECH ON SHIFT REINSTALLED THE FLOOR BOARD AND I SIGNED OFF THE LOG PAGE THINKING THAT I HAD FIXED THE PROB. THE ACFT WAS SCHEDULED FOR REVENUE FLT AND I WORKED THROUGH MY BREAK TO GET THE PROB RESOLVED. LITTLE DID I KNOW; THERE WAS A CONDITIONAL INSPECTION REQUIRED AFTER A GALLEY LEAK OF ANY KIND ACCORDING TO MAINT MANUAL. I DID NOT PERFORM THE CONDITIONAL INSPECTION. FURTHERMORE; I DIDN'T MAKE MENTION IN THE CORRECTIVE ACTION BLOCK THAT I HAD ACTUALLY DRIED OUT THE AREA BENEATH THE WET BLANKETS BY REMOVING ANY MOISTURE (WHICH I HAD ACCOMPLISHED). I HONESTLY KNEW NOTHING OF A CONDITIONAL INSPECTION.
