NTSB performs a similar function to AAIB but they are not only
responsible for air accidents, but all accidents in the national
transportation system, which includes road and rail. They seem to
investigate major accidents thoroughly. Their investigation staff may
be spread too thin to investigate accidents that don't have a
significant impact on public safety. Just speculation of course but it
does seem consistent with the standard of investigation that I have seen
for accidents that I knew something about before the report was
published.

In the UK, we split the functions between the RAIB, AAIB and the police,
for railways, aviation and road transport respectively.

Both of the AIBs publish extensively documented, detailed reports, after
thorough investigations. I've tried, and failed, to find similarly
detailed reports on the NTSB web site. Are there any?
