EC130 Technician reported disagreement and confusion over the correct procedures for signing off an MEL that was not corrected and was reapplied to the aircraft to extend the time for repair.

Narrative

DATE. While I was in ZZZ1 working at the [Company]; my lead mechanic told me the regional maintenance manager; NAME; and NAME1 were in ZZZ2 working on Aircraft X. They were trying to fix a MEL and needed parts. He asked me to drive to ZZZ2 and bring them what they needed. I called NAME1 in ZZZ2 to go over the parts and tools needed. When I arrived at the ZZZ2 base; they had ceiling panels removed from the [aircraft] while trying to fix the Tracking System. I brought in the tools and parts and assisted them with troubleshooting the tracking system. After troubleshooting; we narrowed it down to the tracking antenna. I asked my RMM if they had that part and he replied 'no.' Then I asked NAME how many days were left on the MEL. To which he replied; 'It expires today.' I stated; so are you going to request an extension? NAME replied; you cannot extend a category 'A' MEL. I replied; so will the aircraft be grounded? NAME replied; no we can sign it off. I looked perplexed and said 'I didn't think you could sign off an MEL without fixing it?' He assured me that we could. My confusion increased. We were on the Heli-Pad when this conversation took place. I then put the chopper spotter underneath the aircraft to move it back to the hanger. When in the hanger; NAME asked me if I could start working on the MEL paperwork. This question caught me off guard because until two hours ago; I didn't even know this MEL existed. NAME and NAME1 were the two mechanics working on this MEL. Why would he ask me to sign it off? He is an A&P and the one working on the aircraft. For the second time I asked; are you sure you can sign off an MEL when the item is not fixed. I don't know what to write for something like that. I wasn't understanding what he was saying. With frustration; NAME assured me that it could be done and that I needed to look at our company's GOM. I told NAME I didn't have my laptop with me because I thought I was just bringing parts. He told me I could use his. I then attempted to navigate his laptop and access the GOM. After reading through the MEL portion of the GOM; I couldn't find any instructions to sign off an MEL that had not been fixed. I thought; maybe I am missing something and asked NAME for clarification. I approached NAME for the third time on this topic and asked 'NAME; I don't know how you sign off an MEL in the corrective action section of the logbook when the MEL wasn't corrected.' NAME looked at me; visually frustrated; and with a raised voice said; 'I will just fucking do it myself.' and stormed off to the log book. This response shocked me because his demeanor towards me was so angry. I felt threatened. I was only trying to make sure we were correcting the MEL properly. After asking multiple times if we could sign the MEL off the way NAME was describing; I began to doubt myself. I thought; maybe I am wrong? He is my superior and has told me this is the correct way to sign it off. Even to the point where he was cursing mad. As he started to look through the logbook; his frustration grew. He started to yank out supplemental log book pages that were not properly stapled to the log page. NAME turned to me and asked 'Why haven't you fixed this?' I hesitantly replied; this is not my aircraft or logbook (My home base is in ZZZ1.). This is the first time I have looked at this logbook. With frustration in his voice he said; it doesn't matter why it's wrong. It's just wrong. That's the problem with the mechanics in this company. No one wants to do their job. After aggressively stapling the SUPP sheets to the log sheets; he verbally told me how to sign off the MEL in the physical log book while he signed it off in [Software Company]. I hastily reacted; and signed it off stating that I trouble shot the tracking system ops check failed. NAME told me as long as we attempted to fix it; that it could be signed off and then re-opened for an additional 20 days. So that's what I did. Looking back; I wish I would have listened to my A&P knowledge and what I thought was the right way to handle the MEL. Instead; because I felt manipulated and bullied; I signed off the MEL as my superior requested. He had created a hostile work environment and even though I had the choice to say no; I felt like I didn't. In addition; Maintenance Control approved the logbook sign off so I assumed it was the correct way. However; after the fact; I still felt uneasy with the decision I made. I decided to speak with several A&P mechanics who assured me that an MEL could not be signed off that way. This is when I was positive I had made a mistake. I allowed myself to be bullied into making a decision I was not confident in. I take my job very seriously and want to be the first to admit I made a mistake. In the future I will do my due diligence to not be swayed by others.
