Narrative:
I authority/authorized flight crew at ind to defer maintenance of a leading edge slat indicating system which requires pulling (asymmetric mode) circuit breaker MEL 27L on jun/sat/94. Due to a flight crew refusal of aircraft at mco I had FBO mechanic accomplish an operational check of the leading edge slat indicating system and clear the deferred item. I failed to have FBO at mco reset the asymmetric mode circuit breaker. The aircraft flew in revenue service until a flight crew discovered pulled and collared circuit breaker.
