Aviation 'checklists' are in several categories.
Emergency drills and procedures in the approved flight manual (AFM) must not be changed without approval from the manufacturer / regulator because they relate to the safety of the specific aircraft / systems. There are a few normal checklists in this category which relate to system checks and continued airworthiness.
Other checks and procedures are published in the flight crew operating manual. These may be customised, but prior agreement (no technical objection) with the manufacture is recommended.
The processes are deep inside certification requirements CS25, including part 25.1518 AFM
General web search, check histories; also consider medical checklist advice.
