This area is NOT
a place for speculating
about recent accidents. It is a place to discuss probable cause documents once they have been published.
At this link, you can find over (650) RV probable cause documents published over the last quarter century: http://www.vansairforce.net/AccidentsAndSynopsis.htm
This list lays out the as-we-know-them facts, I whole-heartedly encourage you to discuss them here (using the PC as a starting point). Hopefully we can learn something to help us become safer RV pilots in the process. Please give the hobby the safety mindset it requires. It can be brutally unforgiving of inattention and/or recklessness.
If your post here doesn't start with the probable cause ID # and publish date, it will be deleted.
