If I remember correctly, the progon m that crashed in 2013 did have at least some of those design features for the accelerometers, but the mechanics just hammered the sensors “in place” as the wouldn’t um “properly fit” turned out they were upside down ...
- WalterBright 8y agoI heard horror stories at Boeing about mechanics who were sure the instructions were wrong, and would go so far as to use adapters to hook things up backwards. This is why the design tries to make it as hard as possible, plus making it easy to inspect and determine if it is wrong, plus adding it to the preflight checklist.

Therefore, if you can't get them together again, there must be a reason. By all means, do not use a hammer. > -- IBM maintenance manual, 1925 More seriously, there need to be strong cultural norms against hammering the components, and against making components which need to be hammered.
- userbinator 8y agoI have a few automotive service manuals with similar warnings --- with the exception of parts which are press-fit, brute force is not necessary to assemble components. It seems more like another instance of "build an idiot-proof system and the world builds a better idiot."
