That's not surprising. Also not surprising is that nobody trusts you.I don't trust most mechanics.
Your credibility and judgement, of which you openly brag (and post on the web) frequently make you an object of ridicule, like a signpost of mental density. There's something about the way you operate in which you just don't "get it." Most agree that given a little time, you'll nearly certainly be a smoking hole in the ground, or a splash in the water somewhere.
You seem to revel in your inexperience, celebrate your own ignorance...and then in true arrogance, ignore it completely.
Of course, as you're quite the expert on what's required to conduct the inspection...why aren't you doing them yourself. Oh, that's right. You're not qualified. How about that? Perhaps not such an expert after all.
You're performing all your preventative maintenance from current publications to which you hold a subscription, using calibrated tools, to the same standard required of any certificated mechanic?
