  • Service Bulletin 66

    Does anyone have a copy of Service Bulletin 66? It has to do with a safety device for the fuel valve.

    Is this the small spring loaded safty lever what has to be OVER the fuelvalve pullknob so you can not pull it insted of the carbheat.
    Several craches occured becuase some pilots shut the fuel off instead of pulling the carbheat on!
    It is a simple little spring loaded part made from sheat metal what I have to fold out of the way in order to pull the fuel off.
    is what I be of the fan stops!

        I was making them for a while from thin stainless. I stopped when the blood loss started making me dizzy. ;-)
        I have a drawing of the flat shape of the metal and these two pictures show what they are talking about. If there is interest I will try and scan the shape. It would be better from spring steel and it does NOT keep the knob in, it just lets you know it isn't the carb heat your fingers are on! Even the spring steel ones need to be bent tighter every once in a while and eventually crack and fall off (which is why so many planes don't seem to have them).
