The only checklist that is authorised for any type is the one in the POH.
mmmm..... Authorised by whom precisely?
The ANO requires you to ensure that the flight can be made safely. This is a nice bit of catch-all legislation designed so the can get you any way they want. Would you care to specify where it says you have to use the checklist in the POH?
If you'd had equipment added and modified your check list to incorporate it would you be in the wrong?
