I had a client took his plane to a shop at another airport in the DC area, and they handed him a discrepancy list of like $25,000 worth of stuff, but looking at the list it looked to be about 4000 bucks of stuff. When he showed him, the documentation that a few of the write ups were trivial and actually allowed by the manufacturer, or how you could treat the corrosion on the rear wing attached fitting without pulling the wing off, the shop rolled his plane outside told him to go F himself and then faxed the discrepancy list to the Washington FSDO and told him the plane had to leave on a trailer. I fixed the three discrepancies that were legitimate on the ramp and then we ferried it over to my shop and fixed the rest. The FSDO guy said he’s not giving a ferry permit, even though I had inspected the aircraft, so we got the DER that he hired to engineer the wing skin crack repairs to state that it was safe for not more than 100 hours of flight time. Then he called the FSDO and got into a fight with the inspector because he still refused to give a ferry permit saying it was unairworthy, even though the DER says you don’t get to tell me that it’s not airworthy because I’m actually a designated engineering representative of the FAA and I’m telling you that it is. But it was really crazy how that went.
