But it hasn't been answered fully, at least not beyond a very general sense. We still don't know what caused the individual parts, of the individual examples, to fail. And what common thread lies therein, or threads. Each situation of how each crew got themselves where they did, and how each crewmember failed in their respective responsibility in terms of what convinced them at the moment of what they fully believed to be right? That can only come from sources within the investigation of each individual case that likely won't be released publically; and that is the crux of the repair in order to help patch the "system" as a whole. I agree there was a problem in these particular cases; do I necessarily agree that there is a breakdown in the system as a whole? Im not thoroughly convinced of that yet.
Orange Anchor and I had a long discussion about this before his passing.
All the questions you asked were asked during the "reset" at airways.
The thing is, looking at it from an investigator's standpoint, you'll never be able to hold a smoking gun. Because you'll say either "yes the crew followed procedures" or "no the crew didn't follow procedures". I'll bet in both of the latest high visibility incidents, the crews followed the procedure, making only a minor error.
You'd really have to go into a single company, evaluate the incident reports and look for a common hole. You have to see what isn't in the report. I'm not trying to get all new-age holistic, but that is the only way to solve this issue. Kind of like saying someone who's never been in a wreck is a great driver. Sure they speed, they eat, they text, don't use their indicators, but haven't wrecked. They obviously don't need to change.
When you review incident reports (asap is great for this) from the mundane to the severe, you start to see trends.
At my company, you very rarely, if ever, see a report that mentions a first officer intervening or suggesting or even providing information. If the FO is mentioned, it's either only to mention if they were flying or not, and if so what buttons they manipulated. So that relates back to @
Seggy's post.
Another place to see is post-incident changes on the company's part. Do they band-aid what they think is a solid procedure by adding a extraneous step to their perfect procedure (in a previous shop we ended up checking fuel about 5 times prior to takeoff), or do they, as part of the analysis of the incident, try to see if procedures as written will replicate the unwanted results? Do they ask questions of the procedures or give answers because of the procedures?
If you're not using your incidents to test the effectiveness of your procedures (most companies don't), it is cycling back to putting the pilots at fault and not looking for the hole.
It's an interesting thing, this hole, you can't ever point to it. The approach I'd to find the rim - which is the common gap in a company's culture that can only be found by looking for what's not there. So you can't say Southern jets had 15 altitude busts last week. The industry has a CRM problem.
However, what you can see is that Southern jets had the highest rates of altitude busts in their most automated jets, Beachball International landed at the incorrect airport the most times with their most automated jets. The ugly Eskimo had the most gnes with their most automated jets. Why does each airline seem to have basic errors with their fleet that allows the most SA and ability to monitor.
Sorry, that's the best I can attempt to convert what's in my melon. It's very conceptual that you're looking for what's the common omission versus hard evidence.
