I worked on air traffic control radios, about a third of the time the entry in the maintenance log was "could not duplicate problem".
The fun entries were "adjusted relays with screwdriver". Now, for those who don't know, relays generally don't have a screw adjustment, but if you tap on the outside casing, they often unstick.
Good 'ol percussive maintenance.
The true key to percussive maintenance, knowing where to hit and how hard.
I've seen people try to replicate good percussive maintenance and fail due to not knowing where and how hard to hit things. Those were expensive mistakes.
