Narrative:
On jan/mon/00 at XA30, I was informed of an incident where the throttle 'bolt' fell out of an engine we changed on the jan/sat/00. The bolt in question was installed on the engine from the overhead shop. There was not a tag stating that this bolt was not safetied. (The nut is on the inboard side of the engine and not readily visible.)
