Cessna C337 SID

[Skymaster337B]

At last year's IA seminar the head FAA maintenance guy told this to the group, "that the only required maintenance manual is the one at the time of production." This is very applicable to much older airplanes certified under CAR, like the Skymaster was. The key word is "required" that doesn't stop any one from using new data however. I'm sure the reference was in an FAA or NTSB ruling, but since you asked I guess I'll have to search for it.
