What I MEANT, and expressed without the necessary disclaimers and caveats, was that the FAA (also P&W, GE, Rolls, Lycoming, Continental, and the rest) do not want you to get creative with their approved engines in approved aircraft, and that any specific knowledge and experience of non-certified engines and aircraft an individual A&P mechanic acquires will have to come from outside of his work and his training for work. I didn't think I implied a lack of ability to be creative among A&Ps, many of whom I know and respect, many of whom do very interesting projects outside of their workplaces. I should have expected that someone will always make the unintended inference. I should have been a lawyer so I'd remember to cover myself against every possibility of offending anyone.
