Résumé : |
This article explains the process of creating an interface loads certification report and its required contents. This report provides the loads the airframe will experience at the attachment points of the interior unit depending on the various aircraft loadcases.
For new graduate engineers, it is worth noting that this industry is always looking for certification stress engineers. |
