Ceramic conductor blocks ITD0053 and ITD0054 were replaced on TM2. Initially, only ITD0053 was to be replaced but after removing it it was noticed that ITD0054 (the larger conductor block behind it) was also broken, fractured through the helicoil that retained ITD0053 (see attached picture).
Both the old 53 and 54 fell into multiple pieces upon removal (see attached photo).
Fasteners holding 53 and 54 to the mounting plate and each other had loose washer on them. I have never seen this done before and, after checking drawing ITA3560 (extraction column Assembly) and confirming they have not been called out, I removed them before reinstalling.
