Geez.
The Cherokee 180 that I fly just came out of a 100 hr inspection today, and she's covered in greasy hand prints.
All over the cowling, the wheel pants, and just about everywhere else our mechanics worked.
When I was working at a larger FBO as a mechanic, that was a big no-no. ANY time a smudge or any sort of mark
was left on a surface in the course of my work, it was removed immediately (not later, when it had baked in). Company
policy, no questions... just keep that airplane clean. I was happy with this rule, as it was just another way to show the
customer that we were careful with their plane, and paid attention to details.
At the current airport, I'm sure our guys are decent mechanics, but they've gotten lazy in that they'll leave a customer's
airplane all smudged and greasy with the idea that the line guys will eventually get to washing it before it's returned to the
customer. Our own planes don't even get that much respect... though I try to keep 'em clean when I get the time.
Maybe it's just me, but if a mechanic isn't going to bother washing his hands before putting the cowl back on, or won't bother
cleaning up his greasy paw-prints... I have to wonder what *other* shortcuts he's taking.
