I’m not certain I understand your point. This incident happened back last February, the NTSB then began an investigation and investigations take time. Once they determined a preliminary cause, the actuator built by Collins they informed Boeing and Boeing’s response was a lackluster message saying at some point the actuator needs to change and then recommended a dangerous workaround.
The NTSB, already stating that the workaround had risks and seeing that Boeing wasn’t moving fast enough or the FAA wasn’t responding with any seriousness put out a safety notice. So where’s the criticism towards the NTSB? How are you seeing this from a political point of view.
If you’re finding fault, look no further than Boeing because when told of the issue not only failed to respond in an immediate fashion but it would seem fail to inform international carriers. I could see fault with the FAA for not pushing harder on Boeing. I’m not saying the NTSB is perfect, but their job is to investigate and inform, not enforce. If you have a problem with the lack of enforcement feel free to make complaints to the FAA and to Congress.
