Putty/epoxy cement for aero applications
Putty/epoxy cement for aero applications
(OP)
Hi all, recently i completed a project for a company who deals with planes. Unfortunately, there came a pit on the outer surface of the part.. The part is going to fly in air so aerodynamicaly its not acceptable. What i did was that i filled that pit with putty used for painting but the company engineer demands some tests to demonstrate that it will be safe during flight and some other assurances regarding its adhesion with metal which is aluminum obviously.
Is there any recommended test/ standard/ article/ practices which could guide me how to solve this problem? Any help will be highly appreciated.
Thank you in advance

What I'm less sure of is if at some point we'd qualified the filler in that application or if it was a case that if applied in accordance with the manufactures instructions it was qualified by their approval.

RE: Putty/epoxy cement for aero applications
The problem you have is that unless you have thorough documentation of everything involved in the rework process there is no practical way to prove the quality or properties of the repair. The only option would be to remove the existing patch and repair it again using a controlled/validated process and materials, plus documenting anything required for QA purposes. Once you have documentation that the repair was performed in accordance with a controlled process and using specific materials, you can demonstrate by analysis that this repair will have certain minimum properties.
