When Are Allowables Conservative?

Abstract: Aircraft designers are legally required to treat manufacturing variability so as to minimize the probability of structural failure, pursuant to Code of Federal Regulations (CFR) 25.613. The usual design strategy employed for compliance with the regulations is the use of allowable values. However, allowables are not guaranteed to satisfy the regulations as written. In this work, we thoroughly investigate the use of allowables via a formal reliability analysis using quantile evaluation. We find that allowables a… Show more

“…These criteria have been in-use since at least the 1960's [2], but their limitations were only formally recognized recently. While prior work has thoroughly articulated the technical issues in these flawed design criteria [1], [3], the present work aims to support formal study of how engineers recognize and treat variability, with an eye towards understanding how the aforementioned flaws evaded notice for over a half-century.…”
