Narrative:

Was brought to my attention that the throttle lockout and stow switches were installed incorrectly on aircraft. The key washers were installed backwards and on the wrong side of the mounting bracket and the switches were incorrectly clocked.our mechanic was the mechanic on the job had never done the job before; I don't know if any leads were helping him that I saw. I got with him at the start and showed him were to start and to measure the inside stop nut for reference of where to start for rigging the stow switch. I visually checked once installed and checked the measurements and were correct per amm 78-37-01. I did make him re-safety because it was incorrect. Operations test was good. The throttle lock out switch was removed to get access at the stow switch and not to move the inside stop nut for ease of rigging; measurements good and operations checks good.need to have a trainer on the floor helping and instructing of jobs. I as an inspector I'm not supposed to train or help do the job.
