Trump fired a bunch of aviation safety and regulatory personnel as soon as he took office because they wouldn't kiss his a$$, and possibly to prevent his buddy Elon from being fined for multiple safety violations by SpaceX. Shazam, almost immediately a plane hits a military chopper over DC, and a medijet goes down over Philadelphia.
It's probably too soon to blame His Royal Orangeness for this, but deleting those people whose primary responsibility is air safety is NOT going to improve the situation.
