South Korea Jeju air plane crash
- Thread starter bingham67
- Start date
A lot of iffyniss around this.
Probably persecuted by the people who couldn't look past the berm despite looking past the 40 other things that led to the plane being in that orientation in the first place. Sad.
Take that 175 passengers, pilots shouldn't have crashed in the first place.
Looks like they've identified similar issues at other Korean airports and will now take steps to rectify the designs.
Also, not sure if he has inside information, or if he is just speculating (after saying at the start of the vid he won't), but he seems pretty clear to be suggesting that the 4minutes of data from both recorders is likely deleted. If it has, I'm pretty sure the NTSB will know for the data recorder they had.
Surprised this is a controversial take you
It is starting to sound like suicide IMHO.
Based on what?

I'm not convinced, but could be, but either way there is an air of cover up to this now.
The catalogue of absolutely incredulous errors leading up to the no-gear landing, the recorders being wiped. I don't know enough how planes work, but given the importance of the data recorders in crash investigations, I find it laughable to think they aren't on some tertiary back-up power system that runs regardless of anything screwing up.
Edit: unless it is a bit like that sky diving pilot who off'ed himself when he cocked up that landing. Decided the wrath/cancellation of his career wasn't worth living for.

Panic in the cockpit is far more likely to me, maybe even Korean culture played a part like it has before.
Yeah I agree -- just super curious about the recorder situation. Is it common for pilots to turn them off if they have cocked something up?
I would be surprised if it was possible for the pilots to be able to disable the flight recorders, but not something I know about. Those that do (and I think a poster in the thread that works on aircraft maintenance also mentioned this) can't think of a scenario that would result in power loss to them - though that might just be from a bird strike/engine shutdown point of view, rather than malicious intent. Certainly I would be amazed if a pilot could just "pull fuses" from the cockpit. If data has been removed, from my understanding this would be apparent as the recorders are constantly overwriting old data, so while somebody might think they can just delete data and it would look like the power stopped, the device would actually have the equivalent of 4 minutes of blank data space. So it should be obvious to independent investigators if this had occurred. It will be interesting to see what scenario they come out with to explain it.
Edit:
In fact, from that video, pilots can indeed just turn the recorders off.

Yeah I agree. I just can't think how a fault would make it go dead though - seems a very big design oversight if an "issue" causes it to stop working. You'd expect it to want to work no matter what "issue" may occur. But you can't prevent against a breaker/fuse being pulled to totally kill the thing.
In the panic of the landing though, like sols said, probably no time to **** about with breakers to cover your tracks (unless that's what was taking up all their attention).
The experts have already said the time between bird strike and landing physically isn't enough time to even read the manual --- so could all come down to pure incompetence with "tracks" conveniently covered...
Watch the video!.... Or just skip to the wiring schematics.
They were operational only the last 4 minutes are missing.
Ah I missed that bit, apologies. In that case it could've been a million things that took them offline but pilot intent would be very far down my list of suspicions.
Yep - seems the design intent is to pull the breakers after an incident to stop them overwriting themselves.
Perhaps they pulled the breaker following the bird strike assuming it was the "incident" that needed to be saved.
Edit: Most likely is AC power lost though. Seems really daft that an engine out can stop the recorder - feels like recorders should have guaranteed power vs. single point of failure requiring intervention from a pilot?
P.S> Chuck Palaniuk wrote an epic book called Haunted about a voice recorder being the catalyst for escalation. Very much recommended.

Its not a single point of failure or one engine out, you need both engines down for it to happen and the APU not on. Obviously here it looks like both engines went down for whatever reason and no time to do anything else but try and land. Both engines going down resulting in a full loss of power in flight is incredibly rare.
Yeah, it does appear that one engine is still operating though on landing and I've seen it mentioned that they didn't have enough height to go around and land like they did without some thrust being provided.
