Narrative:
On oct/xa/99 aircraft xyz arrived in ZZZ on flight XXX at XK45. During walkaround, found hydraulic service center drain mast missing -- knocked off from base. Informed mechanic in charge wxxyy of damage. Entered item in aircraft log and referred to MEL and cdl. Conferred with mechanic in charge and no references to drain mast in either MEL or cdl. By mistake I mco'ed and placarded missing component MEL/cdl not applicable. I thought about calling air carrier maintenance coordinator about maintenance carryover entered but, not being a critical system component, I didn't. In the future, whenever in doubt, I will call air carrier maintenance coordinator to verify the proper methods to follow. In which this case an engineering variation authority/authorized was necessary as informed by air carrier maintenance coordinator after aircraft had departed on schedule XM00.
