Still I'd have to say the narrative I outlined above is more of an attempt to hang the crash around his neck than something that reflects the truth particularly well. Of course Trump for his part as always immediately tried to hang it around Biden's and Obama's necks (neatly skipping over his own prior administration) with no evidence, so turnabout is fair play. Now, whether the Muskification of the whole government will be the cause of problems going forward, that's another story.
I was writing something here about having great confidence in the NTSB to perform a thorough investigation and account for various factors if they're allowed to remain independent and operate without interference... and then I saw a post from the NTSB today that they'll no longer be sending out email to media and instead only posting updates to their Twitter account... so put a lot of emphasis on that "if."
The reality is that most of this either had no effect or not enough time to have an effect, but whether it has bite politically remains to be seen. My view on it is that it's an explicit attempt to use Trump's own tactics against him.
From what information is currently available, the actual investigation will likely blame pilot error on the part of the helicopter pilot, but also decades-old systemic problems with ATC understaffing, crowded and awkward airspace at DCA squeezed too much by increased traffic and no-fly zones, and years of "accepted practice" that normalized an unnecessarily dangerous situation, all of which are solidly bipartisan problems. (The Philadelphia crash I haven't read much about; I would guess it probably won't have as much in the way of broadly applicable takeaways for the aviation system, but it coming in such quick succession certainly helps build narratives.)
