Narrative:
I was trunnioning the lpc [low pressure compressor]. The balance arbor became detached from the lpc during the trunnion process and fell to the floor damaging 12 each 2.3 blades. The tooling work bolts used to attach the arbor to the lpc were provided by egat and were too short. Suggestion to add a caution to the jic [job instruction card] stating the minimum size bolts to use when attaching the arbor to the lpc.
