For your reference: MIL-HDBK-516B which is a nice summary

Interesting. However, I would call that specs or a standard. Certification in any industry has a very clear meaning/definition. It is a process in which a third party judges if a product or a service meets a (industry) standard. If it does, the third party will certify it. That MIL-HDBK-516B is certainly such a standard/spec, but nothing is certified unless a third party has assessed it and – certified it. The military cannot certify it’s own items after it’s own standard and call them certified, nobody cn do that. It would be like Lufthansa certified Boeing aircraft. The key for certification is a third party. Nothing wrong with calling the standard/specs for certification criteria though

“It would be like Lufthansa certified Boeing aircraft.”
Lufthansa might have been more independent in scrutinizing the Max than the FAA. :-(

A good point actually, and you could be right. Certification is only as good as the weakest link in the certification body. There is no law of nature that say the end user is not the best entity at verifying the performance and quality of the equipment directly with the producer. The main thing certification does is to free the end users for the necessary competence to do exactly that.

There is also another dimension to that: one can design a product for certifiability from the outset, but it does not necessarily mean an actual certification process will (or needs to) be conducted. Conversely, one can design a product minimalistically and then keep adapting it to squeeze it into the certification requirements.

Raptor crash-landed in a cornfield. The pilot/builder survived. I hope he comes to his senses with respect to his engine choice…

Very interesting, In a way I’m pleased it’s out of action with no one harmed, as it does seem to be a bit of a bodge all round.

He appears to have gone for a gear down landing, with both pretty feeble landing gear, and a high approach speed. Although with it’s shape and weight maybe snapping the gear off would just help shed energy.

WOW ! Glad nobody was hurt
