Could someone fill me in on the Aerostar fuel system? The one in
question is a 602P. IIRC, Ted Smith designed it as a "Leave it alone and burn all the fuel in the airplane" type system. But wasn't there a lawsuit over one years ago? Al G |

Cheyenne, WY I seem to remember, a looooong time ago, perhaps right after Piper resumed building Aerostars that an AD came out that required separate fuel gauges to be installed. The result was the three fuel gauges now seen at the top and center of Aerostar panels. Now . . . I could be completely wrong, and if I am, I hope someone with a lot more Aerostar knowledge will add to this thread. Take care . . . John |

Just found this . . . see http://www.planecheck.com/aerostar.htm
"The Aerostar's fuel system has been the subject of some criticism over the years. The aircraft has three tanks - one in each wing and a central fuselage tank mounted mid-way up behind the rear cabin bulkhead. The system holds 165.5 gallons of useable fuel. The intention was to use tank vents to maintain an equal level of fuel throughout the system. As the wing tanks depleted however, fuel feed would come from the fuselage. It is important to always have fuel in the central tank and although the system is designed to accommodate this, a number of accidents have followed simultaneous engine failure caused by uneven feeding. The number of Aerostar incidents caught the attention of the FAA who issued an airworthiness directive mandating the use of a low fuel warning light for the central tank. In 1979, the FAA issued a further AD forcing owners to install a triple fuel gauge - one for each tank. The AD also called for fuel cap inspections as it was suspected that negative pressure was responsible for restricting fuel flow causing premature depletion of the fuselage tank " Take care . . .

John Thanks, I was asking because a friend got killed in one Friday, from apparent fuel starvation. http://www.ntsb.gov/ntsb/brief.asp?e...13X01789&key=1 I originally thought that it would be hard to burn the thing dry on a 508nm trip. With headwinds and a short fuel load to begin with, it becomes more plausible. Al G |

Similar situation in Super Vikings... There it has a gauge for each
tank and the gauges read the tanks in use... The problem was that the unselected tanks would show some reading, not having anything to do with the actual fuel in them because the gauge was unpowered when the tank was not selected and the needles would drift wherever they would... The pilots manual was clear on this, but some folks can't be bothered to read... So, guys would look at the aux tank gauges and it says 2/3 full and they would take off... But the tanks were not near full and the reading was spurious until the gauge was powered by selecting that tank... More than one Super Vike bought the farm because some pilot didn't understand his machine... denny |

How damn hard would it have been to just power the guages all the time? |

I am not saying it's not worth it, but I wonder if you can discern a real difference by looking. It seems like it could be hard especially on an unlevel surface. IIRC the Aerostar POH specifically cautions against fueling on uneven surfaces. take care . . . John |
