NASA Tech Inspection Form

[Rojoryu]

For anyone with experience running with NASA, who do you have sign the tech form or do you sign it yourself? I ask because I have been having a local shop inspect and sign and a co-worker who runs with NASA says he signs it himself. NASA's website just says that any qualified mechanic can sign but it doesn't specify what "qualified" means. Have I been wasting time and a few bucks by not signing off on it myself?
