Narrative:

Aircraft xyz arrived at gate with the 'center autoplt disconnected' write-up. The last flight report on the mcdp (maintenance control display panel) showed the center FCC had failed. Avionic technical center was called to issue an MEL for the center autoplt and down-grading the aircraft for CAT approach. The MEL procedures were followed and the special procedures accomplished in writing in the corrective action block the MEL numbers and verbiage, I became concerned to note the center FCC had failed. After entering this I entered the CAT status required item and down-graded the aircraft to CAT ii/IIIA per MEL. I read the sign off asked another person to check if it was correct. Satisfied with my work and sign off I released the aircraft. The next morning on my way to work I realized I forgot to enter in the action block the verbiage 'complied with specification procedure XXXX.' the special procedure consisted of checking the FCC's for sensor data on the mcdp, checking the circuit breakers are in, and then pulling and collaring of the failed FCC servo circuit breaker. The next maintenance ron (routine overnight check) the FCC was replaced, a satisfactory R-5 card test relative to the FCC and autoplt system accomplished and the aircraft certified for CAT ii/IIIA/IIIB and MEL removed.
