Under no circumstances overlook that obsolescence is a challenge with  supplies which will current enormous substitution issues Sooner or later. Regards, Wil Taylor
In order to be grievance While using the Significantly regulation (product 23.613), one particular inexpensive process is to pick supplies in MMPDS that consist of both A- & B- Basis allowables which can be acknowledged inside the industry.

So even though I do not think the information can be that A great deal different, I do not know you can get FAA approval.  I'd be interested to hear usually.   Brian
GENOA MS- PFA GENOAÂ is really a longevity & harm tolerance, progressive failure, and dependability application that gives engineers with predictive computational technological know-how to characterize and qualify Innovative composite materials and structures.
