Narrative:
Aircraft was in hangar for a mid visit. During this visit, a dent was found on fuselage skin r-hand side, approximately station 1500, at S-22 right. When called upon to inspect repair and give ok to install, I recommended an engineering revision authority/authorized, knowing that this repair differed from approved repairs in our srm. Engineering would not write an engineering revision authority/authorized and created an alternate method to address this repair with creative paperwork signoffs and convinced mechanic and eventually an inspector to sign off repair. I notified my analyst, my foreman, my manager and my auditor of the situation. All refused to take any action and passed the buck to higher auths who never took any action either. I requested assistance of auths outside of airlines, and knowing that this repair would be looked at and the fact it was not an 'immediate' airworthiness issue, I signed aircraft logbook when asked by my foreman to do so.
