Theres no doubt that RMA's relieve the workload on LAE's. The LAE can get on with more serious matters without having to worry about the brake unit change or the boiler that wont brew. Just the paperwork side of things in my company often takes longer than the job. When I first joined my present employ, the RMA's had to carry out some of my tasks because I did not have electrical extension. I had full A & C inc ground run, boro etc but I couldn't certify a reading light change....the mechanic could?
