That's nothing. Talk to the owner/operator of your average Thielert Diesel and/or Robin/Alpha aircraft with planes grounded, lacking a certain spare part which cannot be obtained from the company (in receivership) or through any other means.
In our case (R2160), it was a little aluminium plate, about 3x5 cm with one 90-degree angle and three holes. Would take a skilled metalworker about five minutes to manufacture. But as this forms part of the rudder hinge assembly, it needs to be a certified item. In the end it took us seven weeks to get it delivered from New Zealand, and we were considered lucky!
