Narrative:

Parts ordering support would not be in on wkends. I pulled up the projected night's work. In doing so, several items came to my attention: 1) a delaminated turbo fan duct with 14 hours left. 2) a fuel flow problem. 3) a #1 engine thrust reverser problem. I concluded that the thrust reverser needed an lvdt or aeec and ordered those parts. Upon reporting to work later that evening, I noticed that indeed the aircraft was present at ZZZ and that maintenance had since updated the item, drawing the same conclusions from the meter that I had. Even though I had never been trained B757 general familiarization or otherwise nor worked a B757 thrust reverser problem before. Based on the one and one half hour research of the system and the same conclusion that I had drawn with maintenance, I was both eager and confident that my efforts would result in a successful system repair. Although the #1 thrust reverser proved to be svcable, a successful repair did not result. During the deactivation and activation of the #1 thrust reverser automatic speed brake, I apparently did not reset a circuit breaker which caused the throttle to stop short of full movement upon takeoff from ZZZ. The safety of the crew, passenger, and equipment that were consequently jeopardized by my oversight concerns me greatly.

Title: A B757 MADE AN EMER DIVERSION DUE TO #1 ENG THROTTLE RESTR.

Narrative: PARTS ORDERING SUPPORT WOULD NOT BE IN ON WKENDS. I PULLED UP THE PROJECTED NIGHT'S WORK. IN DOING SO, SEVERAL ITEMS CAME TO MY ATTN: 1) A DELAMINATED TURBO FAN DUCT WITH 14 HRS LEFT. 2) A FUEL FLOW PROB. 3) A #1 ENG THRUST REVERSER PROB. I CONCLUDED THAT THE THRUST REVERSER NEEDED AN LVDT OR AEEC AND ORDERED THOSE PARTS. UPON RPTING TO WORK LATER THAT EVENING, I NOTICED THAT INDEED THE ACFT WAS PRESENT AT ZZZ AND THAT MAINT HAD SINCE UPDATED THE ITEM, DRAWING THE SAME CONCLUSIONS FROM THE METER THAT I HAD. EVEN THOUGH I HAD NEVER BEEN TRAINED B757 GENERAL FAMILIARIZATION OR OTHERWISE NOR WORKED A B757 THRUST REVERSER PROB BEFORE. BASED ON THE ONE AND ONE HALF HR RESEARCH OF THE SYS AND THE SAME CONCLUSION THAT I HAD DRAWN WITH MAINT, I WAS BOTH EAGER AND CONFIDENT THAT MY EFFORTS WOULD RESULT IN A SUCCESSFUL SYS REPAIR. ALTHOUGH THE #1 THRUST REVERSER PROVED TO BE SVCABLE, A SUCCESSFUL REPAIR DID NOT RESULT. DURING THE DEACTIVATION AND ACTIVATION OF THE #1 THRUST REVERSER AUTO SPD BRAKE, I APPARENTLY DID NOT RESET A CIRCUIT BREAKER WHICH CAUSED THE THROTTLE TO STOP SHORT OF FULL MOVEMENT UPON TKOF FROM ZZZ. THE SAFETY OF THE CREW, PAX, AND EQUIP THAT WERE CONSEQUENTLY JEOPARDIZED BY MY OVERSIGHT CONCERNS ME GREATLY.
