admittedly I didn't look too hard, so forgive me if it's already been
hashed-out here.

I was just reading the latest General Aviation News and ran across an
article on the Sport-Jet crash on June 22, 2006.

The jet was cleared for takeoff behind a Dash-8-200 "in violation of
mandatory seperation requirements." When the small jet encountered
wake turbulence upon rotation & liftoff, it rolled and crashed,
causing minor injuries.

Apparently the ATC manual says there must be a 3 minute seperation and
the NTSB "snapshot" put the Sport-Jet in the same area of the Dash-8 2
min & 11 sec. later. Arguments counter that there is no way that the
vorticies would be around after 2 minutes.

Anyway, at first my thought was; It's the pilot's responsibility to
decide whether or not his takeoff is too soon after a large plane's
departure. Personally, I have at least once requested a longer
"position & hold" time from ATC after a Southwest 737 took off in
front of me at Love Field (much to their frustration).
But I'm not so sure anymore. Truly, how many of us give consideration
about wake vorticies departing (or landing) behind larger aircraft?

Who do you think is at fault here?

The PIC who wasn't fulfilling his IC responsibility at the time.
