Its happen in the past and probably will in the future
Its true Machines have come through lacking proper Lubrication or Bit and Adapters without Loc-Tite securing the set screws.
There have been several threads and post in the past about folks having Bits drop out or slide up and down in the adapters, along with set screw being loose, flying out of the machine, or jamming and damaging the Quick Chuck. As you mentioned, how important it is to inspecting your machine for loose parts or screws and proper lubrication, along with the use of Blue Loc-Tite on all set screws in the bit adapters. For my own peace of mind each of my bits has its own adapter, that has Loc-Tite on the set screws and bit, which I do not plan to remove until the bit is dull, damaged or broken. Even so I do periodically check all the machines screws and parts, and each bit and adapter before loading them in to my machine. This may sound excessive and possibly not be practical for everyone, But it’s worked for my so far.
