The only checklist that is authorised for any type is the one in the POH.
Yes, but what does that mean?
1) I must use the checklist as printed in the authorised flight manual
2) I must use a copy of the checklist as printed in the authorised flight manual
3) I must use a checklist that contains the items in the POH checklist (and only those items) but they may be reformatted
4) I must use a checklist that contains the items in the POH checklist (and only those items) but they may reformatted and reordered
5) I must use a checklist that contains the items in the POH checklist but they may reformatted and items may be added but not removed nor reordered
6) I must use a checklist that contains the items in the POH checklist but they may reformatted, reordered and items may be added but not removed
7) I must use a checklist that is substantially the same as the items in the POH checklist, with variations appropriate to operating procedures.
Thoughts?
