According to the FAA Website, the accident aircraft, N236BC, although having a valid registration, did not have a current airworthiness certificate.
Here's a link:

Judging by the appearance of the propeller blades in this frame (at 0:58) of one of the videos available, the engine was not producing power at the time of impact.
R.I.P.
