Narrative:
Engineering authority/authorized rev B me-02 was set-up for ZZZ to rework the bonding capability of a ground stud bracket for the dc generator tru (transformer rectifier unit). Only part of the entire procedure was printed up when I worked the engineering authority/authorized on air carrier X oct/thu/04 and air carrier Y oct/fri/04 and I failed to read through the engineering authority/authorized paperwork completely. It was my interpretation at the time that we were just supposed to do the bonding/resistance check when in fact the ground bracket needed to be removed, cleaned, and reinstalled. This resulted in the engineering authority/authorized having to be reworked on these 2 aircraft.

Title: 2 B767-300 ACFT WERE DISPATCHED IN NON COMPLIANCE WITH PARTIALLY ACCOMPLISHED ENGINEERING AUTH PROJECTS.
Narrative: ENGINEERING AUTH REV B ME-02 WAS SET-UP FOR ZZZ TO REWORK THE BONDING CAPABILITY OF A GND STUD BRACKET FOR THE DC GENERATOR TRU (TRANSFORMER RECTIFIER UNIT). ONLY PART OF THE ENTIRE PROC WAS PRINTED UP WHEN I WORKED THE ENGINEERING AUTH ON ACR X OCT/THU/04 AND ACR Y OCT/FRI/04 AND I FAILED TO READ THROUGH THE ENGINEERING AUTH PAPERWORK COMPLETELY. IT WAS MY INTERP AT THE TIME THAT WE WERE JUST SUPPOSED TO DO THE BONDING/RESISTANCE CHK WHEN IN FACT THE GND BRACKET NEEDED TO BE REMOVED, CLEANED, AND REINSTALLED. THIS RESULTED IN THE ENGINEERING AUTH HAVING TO BE REWORKED ON THESE 2 ACFT.
