If you ignore the part about ANC-19, yes.... "All wood and plywood used in the repair of aircraft structures should be of aircraft quality (reference Army Navy Commerce Department Bulletin ANC-19,...)
Table 1-1 lists some
permissible variations in characteristics and properties of aircraft wood..."
This is a document from the goverment.... you must read it carefully and look at the key words... reference and some
I unfortunatly do not have ANC-19, so I cannot tell you what it says on the subject, and I do not believe it is available online... but it might be.
