What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Mr. Mason made final check/verification of fuel flow valve using his foot, without visual confirmation (valve located under cockpit control panel. The valve does not have a hard stop, so the potential for the valve to go beyond, or short of "full open" is very possible without the operator ensuring this visually. The possibility that, under full power load requirements, the a/c experienced partial fuel starvation, is likely due to the fact that the valve may well have been in a position other than "full open".
