Even a mug like me knows that there has to be " approved data" in black and white for everything and anything done to a certified aircraft. ALAEA Fed. Sec. is absolutely correct.
If reference can not be made to printed approved data, then you are flying an experimental aircraft, period. No ifs, no buts. You are your own test pilot.
This is at the core of the problem with engineering management. They see some engineer look at something and pass it, then make the wild assumption that the airline is paying far too much money for what they think of as a jumped up car mechanic.
