Narrative:
A radar altimeter was removed from 1 of our aircraft for repair. It was placarded and written up in the logbook as deferred for 10 days per our MEL. The expiration of this 10 day deferral was overlooked and was overflown by 5 days, at which time the radar altimeter was replaced. In the future all maintenance items which are deferred will be displayed on our shop maintenance schedule board in plain view of all maintenance personnel. We believe this will prevent a reoccurrence of this type of situation.
