That’s a really good starting point. I’ve done about a dozen aircraft so far, and we started with the template available on that site, then built them out for our operation.They have a boiler plate that gives a good example of hoe to make a good SAFA checklist. Just cut their stuff out of it and paste your info in and you'll be all set. It took me a couple of days working on it to complete my SAFA checklist.
