NTSB issues CV-580 safety recommendations on fuel crossfeed operations
17 May 2006

In the light of the fatal August 2004 accident involving an Air Tahoma Convair CV-580, the NTSB issued three safety recommendations:

Issue a flight standards information bulletin to all
principal operations inspectors of Convair 580 operators
that familiarizes operators with the circumstances of the
Air Tahoma flight 185 accident, including the importance of
closing the fuel tank shutoff valve for the tank not being
used during fuel crossfeed operations. (A-06-39, to the FAA)

Require Convair 580 operators to set the left and right fuel boost pump output pressure settings on their airplanes to the same setting. (A-06-40, to the FAA and A-06-41, to Transport Canada)
