This is again presupposing a design or maintenance instruction flaw.
There's a thousand of these aircraft, and they've each been through multiple D checks where all of this is completely disassembled and put back together; then there's other maintenance that causes disassembly and reassembly, too. In tens of thousands of opportunities, it looks like one time a wheel assembly was not fastened adequately.
It's possible procedures can be improved to make this even less likely. But maybe not: people make mistakes. Sometimes someone signs the line saying that something was torqued and didn't realize they had torqued something different.
- trklausss 3y agoI am not presupposing anything, I am laying out a _possible_ scenario (see all the ifs?). I am just doubting safety procedures where followed as they should, which is the same thing the FAA is doing and that’s why they are investigating. If they were sure everything was fine, they wouldn’t do it. Doubting, and scrutiny in safety-critical environments is not a bad thing, it is what makes things safer. I won’t defend Delta nor Boeing until the FAA sees the t’s crossed and the i’s dotted, and neither should you.
