FAA/EASA Ultimate Test 3 seconds requirements : What is the rationale behind it!
FAA/EASA Ultimate Test 3 seconds requirements : What is the rationale behind it!
(OP)
What is rationale behind holding structures under Ultimate load test for 3 seconds accroding to FAR 25 or EASA CS25 Aircraft certification requirements? In terms of structural failures, what is the 3 seconds no failure at ultimate load testing requirement meant to demonstrate? I have asked this question from 'seasoned' Airframers and no satisfactory response was provided, so I am hoping someone out there perhaps can give more insight behind this requirement.

I have always thought that was the main reason but I thought there was more justification behind the 3 seconds.
