Here’s why I think its an accident and not some kind of gear malfunction the pilot knew about.
1) Short final… my guess is he would have had a longer approach, used more runway.
2) No radio communications from what I heard, they are talking about golf? “I went back there the day after to swap my clubs and everything…”
3) No spectators, usually someone would be out watching the event if they knew it was going to happen, cant see anyone or any vehicles waiting on the ground.
My analysis, but I could be completely wrong.
