Two years ago, there was a fatal crash in Fredericksburg, VA in which 6 people died in a Beech 95-B55. For some reason, the story struck me, and I wrote a note to myself to follow up on it.
The NTSB published a preliminary report 12 days after the crash (on 8/24/2016) but has not published any report since then. Do investigations sometimes end at preliminary reports, or will they someday follow up with a final report?
The NTSB case is ERA16FA288. I searched the NTSB's "Aviation Accident Database & Synopses" page for all events in Virginia on 8/12/2016 (as well as googling the airplane's tail number), and couldn't find anything after that preliminary report.
