Flying N611AS on Saturday as a passenger, looked out the window to see the following "notation" on the flap: http://i.imgur.com/Rr9wN.jpg
While I could see that it was a clean cut and too small to be a flight safety issue, the repair crew's method of communication didn't do a lot to instill confidence in their professionalism or general good sense.
Alaska's T w i t t e r support responded that it was a "permanent approved trim repair," but that the "method of communication was not appropriate."
Curious: By "trim repair," they mean trimming the break to a clean curve, and not something to do with the actual aircraft trim, right?
A stencil might be a better alternative to a Sharpie next time...
