Its shenyang. What do u expect?
Lets not just blame Shenyang, all mechanics who drill too large a hole, fill them with a bigger screw, really, how would you like to go tell the boss, sorry boss, "I just jacked our 60 million dollar prototype and threw our whole plan into the dumpster by using too large of a drill bit". Much better to throw in the larger screws, and hope for the best, been there and done that. Then when it breaks you can blame the next guy, "he told me to". Really, it happens everyday, on every planet in the solar system, and yes I have been paid to work on real airplanes, and I have been chewed out by Klem, when I messed something up. No, really, and yes I have flown those same airplanes that I worked on, most of the time thats the recommended fix, so until we get more details, lets lighten up on Shenyang!
