U/IAM/FAA has a program where the mech can admit his wrong doing and educate the mech force usually with little or no action against the mechanic.I'm not saying the AMT gets fined or time off if the card is wrong but, the FEDS will still put him on the "hot seat" and call him to the office for a chat. Even if he follows all procedures. Again it depends on the location and what FAA office is involved.
of course the severity has bearing also....before someone jumps off the bridge here.
