Percussive maintenance is a real thing!

If it’s stupid and it works, it’s still stupid but at least it worked.

I can only imagine the euphoric mixture of dread and excitement that the engineer who came up with that one must have had right before presenting it to the rest of the team. The realization that all hope for normal solutions had been lost and abnormal solutions were needed, combined with the requirement of absolute confidence in these facts to present this to managers. I am jealous, this is a feeling most engineers only get a few times in their careers.

Not a bad option. A service call from the NASAA would take over a week. Easily.
