True. That statement exists in 20-Q-4. However, the same paragraph also states...

"Without his concurrence, he shall not be required to perform a procedure not covered in Flight Manual Normal, Non-Normal or Supplemental procedures"

I would be very cautious about what MX is specifically asking you to do and or evaluate. Having run into this over the years; my postion has always been that if there isn't a checklist for what they want me to do, then it is outside of my training and job descrition. My job and ticket are far more valuble than 30 minutes of add pay.

Lastly, while the chances that something will go wrong are remote, a word of caution - without going into specifics, I have represented pilots in front of the NTSB. I can GAURANTEE that you will be asked and have to answer to why you didn't use a checklist or why you did not follow the reccomended safety policy of your own MEC (APU's, Generators, TCAS).
