> The point of the investigation is to determine what went wrong before the crash became a certainty. That's the reason for starting the investigation. It is not the exclusive goal for it. Increasing safety for all future flights is a big part of why and how this is done. Bird strikes are inevitable. > Which for Jeju was the moment they lost both engines. It seems like you do not require any investigation at all. > should your commercial air liner lose both engines at 1000' in a descent the outcome will be crash The outcome will be a descent. You do see that the concern here is related to the fact that this failure happened very close to approach and even given this the pilots managed to successfully navigate it to the runway. With the gear up. I mean, if you touch down with the gear up, technically, I'll give you, that's a crash. If the gear was down it would look very much like a regular _landing_. What precisely went wrong considering the gear _had_ been down previously? So.. it's not hard to imagine how a working CVR and FDR here would help us answer that very question. Although, your investigation may have been this thorough, do you have the answer?

The biggest question for me, is what happened between the bird strikes and both engines shutting down? Why was the decision made to go around instead of continuing the approach? How quickly did both engines fail? > managed to successfully navigate it to the runway. With the gear up. Sadly they did not, well technically yes, they did physically locate the runway, however they were also traveling too high, too fast, and crashed. > If the gear was down it would look very much like a regular _landing_ It would have still been a very unstable landing half way down the runway with limited braking, no reversers, no spoilers, no flaps. It's very likely they would have still ended up off the end of the runway. > What precisely went wrong considering the gear _had_ been down previously? They chose to do a go-around, selected gear up, then with both engines failed the only way to lower the gear is manually, the handles are on the floor aft of the first officers seat. Their would not have been time to access them between when they had lost both engines and were on the ground while also flying the aircraft. I'm not saying I know what happened, I'm saying that the key to preventing future accidents like this will be in the moments before they lost both engines. After they lost both engines it's clear they aircrew tried to very quickly turn the plane around and land the runway, I have pretty serious doubts that there was any actions that could've made that a successful landing, and if there was, they'll be found in a simulator not on the FDR of the aircraft that DIDN'T make the successful landing.
