Re CINDAS ASMH -- By Cindas' own disclaimer, the data presented is 'typical' and not 'statistically derived design data' (ie, A- or B-basis data) and as such is a complement/supplement to the likes of MIL-HDBK-5. And while they also attempt to provide references to testing methods, etc., they also state some sources may be non-verifiable.
In my opinion, there is a considerable amount of data contained in the volumes usable for initial material selection, but mechanical properties data for detailed safety-of-flight design analysis is lacking.
As a DER I would highly prefer use of MIL-HDBK-5, MMPDS or ANC-5 before approving structure based on ASMH.
