    Subject: Really pissed off customer
    From: "Johnson, Greg" <gjohnson@cccglobal.com>
    I often get my annual done the same day I bring it in. Maybe you should rethink the possible options. I schedule it 3 months in advance. I have the wheel pants off. I have the access covers off. I have the interior empty and the seats removed. I have it in the shop at 7:30am and I work with the mechanic to complete the job in one day. Sometimes it takes part of the next day - like when we removed the canopy and replaced the track rails. I then put all the parts back on in my hangar. It can be done.

    Hi Gary, I didn't see this last night when I when I checked e-mails. We've been trying to fix this since the first time you worked on the plane and before the bird strike...2002 or 2003. I'm certain this isn't related to the bird strike. I'd love to fix it but don't have any suggestions. Let's keep talking about this and try a few more things like changing the aileron...I wanna get this sorted out.
