Narrative:
On oct/xa/99 I replaced a central aural warning box as per maintenance control as a precautionary action to a problem that could not be duplicated, then performed a satisfactory operations check and made 1 entry in logbook stating same. As per maintenance procedures manual, I should have made 2 entries as worded in the manual due to component being part of a CAT system. On nov/xb/99 we informed maintenance control of the situation with the logbook entry. At this point we were advised to enter second entries that were needed, which we did accomplish. As a mechanic, some ideas that might help to prevent this problem from recurring would be some training on CAT system or placards to identify components that are part of any CAT system.
