You need to convince the FAA of the many errors of their ways.
Like when they and the other xAAs signed off the DC10 cargo-door design.........
Like they etc signed off the CFM56 not requiring testing "on the wing"...........
Like they signed off the 737/300-500 EFIS as suitable for airline use..............
Like they signed off the dreadful "Eros" O2 masks as suitable...........
Like they signed off the MD11 IFE cableworks...............
Like they permit 2/2 engines to have critical work performed at the same time........
Like they signed off the V2500 engine cowl fastening design..................
Like they signed off the A330 pitot tube design & continued use til..................
Like they will sign off the latest FTLs under industry pressure.............
Like they signed off the multitude of Airbus quirks ad nauseam.............
Like they signed off Li-Ion batteries as primary DC supplies........................
Like they signed off cross-wireable engine fire extinguisher systems...............
And so on, doubtless other contributors wll be able to add to the *hit list?

Unless you aren't particularly interested in a proper job being done in the first place?
