The FAA didn’t mandate approved aircraft flight manuals (AFM) for all small aircraft until March 1979. Only those produced after that date were required to comply with that regulation. Now if the aircraft was certified under Part 23 prior to 1979 then there was a separate requirement. But most SE aircraft like the 172 were certified under CAR 3 which did not require emergency procedures and only required aircraft limitations and performance data to be listed in a manual. And if you go back far enough there are some older aircraft where the limitations and performance info is only found in the Aircraft Specifications/TCDS.
Technically, there is no regulatory requirement to update previous POH or AFM to the new standard.
Once the 1979 mandate hit most OEMs switched to the GAMA Spec 1, as mentioned above, which has an emergency procedure section, but there is no separate FAA requirement to use that format. However, by following the GAMA spec it made AFM approval very easy.
