The final report on this accident was issued a couple of weeks ago after nearly 3 years.   Basically no new information was provided.  Continental reassembled the engine with some new parts that had been destroyed in the accident and it ran fine. We'll never find out what really caused this accident, but the only reasonable guess, since they couldn't find anything wrong with the engine, would be vapor lock.  I was coming back from MooneyMax 2019 that day and landed in Chandler a few hours b
