Narrative:

I received a letter from the FAA stating that I did not comply with engineering order. To the best of my knowledge and abilities I did comply with the steps signed for in the engineering order. That morning; crew chiefs and management were wanting power on the airplane; so pressure was on to get the job completed. As for the discrepancies; steps 2.B.(8)(B) and 2.B(17)(B) were accomplished using the carrier repair manual. Sealant was applied in step 2.B.(6); directly under the lip of the rib the bracket was attached to. The remaining bracket covered this applied sealant so as to appear it was not sealed. In step 2.B.(15) was fillet sealed; using a process of applying it with my finger because of a tight working area; giving it a concave look. Finally; I did identify the lower bracket part number on step 2.B.(11)(B) using a fine tip permanent marker; paint was slightly wet. Throughout this challenge of reading and figuring the paperwork and trying to make sense of the steps; my lead mechanic repeatedly checked on my progress to see if they could apply power. Thus; heightening the stress factor. I strive to be a team player and keep the aircraft on schedule; putting pressure on myself to complete the tasks during my shift. I recommend the engineering order come with placards ready to be installed and parts painted with the final finish ready to be drilled and installed. The engineering order was worded in a confusing manner; and with practices not in the norm of routine maintenance. Supplemental information from acn 802421: the engineering order requires installing a bracket in the main east&east bay. Some steps are difficult because of accessibility. I found it difficult to reach when attempting to locate and seat the bracket. Some tooling to locate the bracket in the proper position would have prevented any location issues. Engineering order written poorly some; tasks not real specific. Location of bracket hinders ability to perform all steps perfectly.

Title: TWO MECHANICS REPORT ABOUT THE DIFFICULTIES IN FOLLOWING AN ENGINEERING DOCUMENT TO SEAL AND PROPERLY LABEL A TRANSFORMER RECTIFIER UNIT GROUND BRACKET REWORK ON THEIR B767-300'S.

Narrative: I RECEIVED A LETTER FROM THE FAA STATING THAT I DID NOT COMPLY WITH ENGINEERING ORDER. TO THE BEST OF MY KNOWLEDGE AND ABILITIES I DID COMPLY WITH THE STEPS SIGNED FOR IN THE ENGINEERING ORDER. THAT MORNING; CREW CHIEFS AND MGMNT WERE WANTING PWR ON THE AIRPLANE; SO PRESSURE WAS ON TO GET THE JOB COMPLETED. AS FOR THE DISCREPANCIES; STEPS 2.B.(8)(B) AND 2.B(17)(B) WERE ACCOMPLISHED USING THE CARRIER REPAIR MANUAL. SEALANT WAS APPLIED IN STEP 2.B.(6); DIRECTLY UNDER THE LIP OF THE RIB THE BRACKET WAS ATTACHED TO. THE REMAINING BRACKET COVERED THIS APPLIED SEALANT SO AS TO APPEAR IT WAS NOT SEALED. IN STEP 2.B.(15) WAS FILLET SEALED; USING A PROCESS OF APPLYING IT WITH MY FINGER BECAUSE OF A TIGHT WORKING AREA; GIVING IT A CONCAVE LOOK. FINALLY; I DID IDENT THE LOWER BRACKET PART NUMBER ON STEP 2.B.(11)(B) USING A FINE TIP PERMANENT MARKER; PAINT WAS SLIGHTLY WET. THROUGHOUT THIS CHALLENGE OF READING AND FIGURING THE PAPERWORK AND TRYING TO MAKE SENSE OF THE STEPS; MY LEAD MECH REPEATEDLY CHKED ON MY PROGRESS TO SEE IF THEY COULD APPLY PWR. THUS; HEIGHTENING THE STRESS FACTOR. I STRIVE TO BE A TEAM PLAYER AND KEEP THE ACFT ON SCHEDULE; PUTTING PRESSURE ON MYSELF TO COMPLETE THE TASKS DURING MY SHIFT. I RECOMMEND THE ENGINEERING ORDER COME WITH PLACARDS READY TO BE INSTALLED AND PARTS PAINTED WITH THE FINAL FINISH READY TO BE DRILLED AND INSTALLED. THE ENGINEERING ORDER WAS WORDED IN A CONFUSING MANNER; AND WITH PRACTICES NOT IN THE NORM OF ROUTINE MAINT. SUPPLEMENTAL INFO FROM ACN 802421: THE ENGINEERING ORDER REQUIRES INSTALLING A BRACKET IN THE MAIN E&E BAY. SOME STEPS ARE DIFFICULT BECAUSE OF ACCESSIBILITY. I FOUND IT DIFFICULT TO REACH WHEN ATTEMPTING TO LOCATE AND SEAT THE BRACKET. SOME TOOLING TO LOCATE THE BRACKET IN THE PROPER POS WOULD HAVE PREVENTED ANY LOCATION ISSUES. ENGINEERING ORDER WRITTEN POORLY SOME; TASKS NOT REAL SPECIFIC. LOCATION OF BRACKET HINDERS ABILITY TO PERFORM ALL STEPS PERFECTLY.
