Narrative:

On sep/tue/05; I was assigned aircraft with a service check; chip detection #1 inspection; WX radar antenna doubler and MEL on standby rudder 'on' light. Having completed all work; I troubleshot the MEL to a bad R-21 relay on back of P-5 overhead flight control panel. Replacing the relay corrected the problem. I signed off and cleared the MEL (reference page X). Being unfamiliar with specific MEL; I did not know the flight force monitor breaker on P6-2 panel had been pulled and collared. The MEL sticker in logbook made no mention of sp-2 and maintenance control did not mention breaker when called to clear MEL. Also; there is no cockpit indication that would show breaker out during operations check. I released aircraft to service and not until nov/thu/05 did a crew call in the breaker.
