Narrative:
Aircraft returned to gate because of a thrust reverser light overhead after engine start-up. When the captain called; I told him to cycle the thrust reverser 5 times and it would go away if it was only a stow fault. After captain accomplished this; the light was extinguished. This is per the fault isolation manual. The problem is that I didn't require the captain to enter this in his logbook. I took for granted that this procedure was ok to perform without an entry in the logbook because the captain can perform the procedure without maintenance involvement -- much like cycling circuit breakers to fix problems. I have been notified by my manager that we can no longer use this procedure to clear reverser lights and that I must have a logbook entry and have maintenance come out to reset the engine accessory unit. I do feel that this should be allowed in our program -- just like cycling breakers or reconfiguring the aircraft after takeoff warning.
