Not to step on any EGOs or to burst anyones bubble, but you should really stop calling Maintenance or specifically Mechanics, as Engineers. The guys/gals are far removed from being one or engineering these or any aircraft. When my aircraft breaks or I think it is broken, I want a mechanic to repair and or Fix it. And I would prefer the Engineer to remain in a comfy office somewhere designing a mo better Acft system. And BTW, I was an acft mechanic and I in no way ever thought of engineering anything, I just fixed it when it was broken.
