I agree with you completely that scientific method needs skepticism. Super lab with a legion of white coated scientists sporting clip boards with access to HPLC and mass spec instrumentation would be great.
I would ask, where are the results from GAMI’s testing and research like that.
Since Mike first took this on due to results from the greatest lab of all (real world results), perhaps we can call his efforts a “first order analysis “. To me, at a minimum it then begs the question “what testing was done with G100 BEFORE announcing that is a fleet wide solution”.
My personal take away from these is Mike is making observations and asking “what’s going on here?”…
I also know the owner of the 421 in question. I’ve seen it in the maintenance hangar for pretty much every annual it’s had since its purchase. I saw it at the last annual inspection. In all these years, none of the brown staining or other such issues had been present before he put the G100 in the plane.
As with anything, when something changes on a system, the first question we ask is, “what changed”?
Best regards,
