My interpretation of the evi= dence (I have seen the Chelton data from this flight) indicates the fuel flo= w was set up too high to begin with.

The NTSB's probable caus= e report is now out on Dave Hickman's accident:

The National Transportation Safet= y Board determines the probable cause(s) of this accident as follows:
The pilot's failure to maintai= n sufficient airspeed after takeoff to preclude a stall, which resulted in a= loss of control and an inadvertent stall. Factors associated with the accid= ent are the inadvertent stall, the loss of engine power due to the pilot's i= nadvertent activation of the high pressure auxiliary fuel pump, and the pilo= t's failure to abort the takeoff after receiving abnormal engine and fuel fl= ow warnings on the primary flight display.
