Bad fuel or poor maintenance or both?
bad vaccine and mandates perhaps?
Good questions. If I had to guess, covid related maintenance (and bad judgement calls on worn out gear based on supply of replacement parts) and stressed out crew.
Many in this country are just damned stressed and out on the verge of snapping.
The stabs.
“Bad fuel or poor maintenance or both?”
You check your fuel before you fly.
Maybe the chickens are coming home to roost?!?
Perhaps the engine vibrations along with some other unknown but common factor induces C/V events that lead to pilot blackout or dizziness that results in the crashes. (The vibrations cause or knock loose clots or cause deep vein thrombosis. )
Or, you could be correct. Bad gas or maintenance. (Did the techs have the required race or gender sensitivity training? Lets hope!)
Rusty piloting skills, errors in judgement, foul weather, but probably not bad gas.
Winter weather
“Continued flight into IMC without qualification”
If your wings are traveling faster than you, you are already in a crash.
Without a break down into general aviation sub-sets where does one begin to even guess. Some very large differences between categories.

There’s a huge hospital/medical campus in my immediate area so medical helicopters are seen and heard all too frequently along with Emergency sirens.
A few years back there was a medflight helicopter circling a major multi-car accident a hal mile or so from me. The chopper sounded like a junker car missing badly, unlike any I had seen or flown in right seat or chartered for aerial surveys, so bad that I called local cops to see if they’d had a distress call...anwer, “nope it’s just X, we get callz all the time but the SOB keeps flying” Always kept an eye out for news about that crate going down.
This subject was brought up a few days ago, and I’m going to post what I did then. I look at Fight24 often. I also live in an area close to several military pilot training bases. I see these guys putting in tons of flight time. At Ft. Rucker Aviation Training Center you can see 30 or 40 Army helicopters in the air every weekday, all day. NAS Pensacola will have several T-38 Texans flying all day, pretty much every day. All of those pilots are vaccinated, but they are not falling out of the sky.
