    Default PA-17 Weight and Balance

    Bless me father, for I have sinned.
    I've owned my PA-17 for almost a year, and I confess I've never done a weight and balance.
    Why bother? It's never been anyone but me, full fuel and 10 lbs in the baggage compartment.
    The plane is in for annual and my mechanic calls me and tells me the information on my weight and balance is bogus.
    As in incomplete, incorrect and yeah. You get the idea.
    There is a piece of paper with a side view of the airplane with the numbers 50" 63" and 155" and nothing else is legible.
    Can someone send me a copy of a completed/calculated W&B for their PA-17 while we go through the process of measuring and weighing everything?
    Thanks

    My original factory report used 64.6” aft of the datum but does not show any calculations.
    I did a weight and balance several years ago and used 67”. I think that was to the axle on the tailwheel even the the report says it was the spring attach bolt. More confusion.

    Thanks to everyone who replied here and by PM.
    I now have a legible copy of the original drawing with dimensions.
    Once I have the new numbers, W&B will be doable and accurate.

    If yours is a standard Vag, with only a single fuselage fuel tank I have a handy Excel W&B spreadsheet you can have.
    Allows you enter in variable weight items to see how your C of G varies with payload..

    Tony, Thanks. It's kind of you to offer.
    Once I got a drawing with readable numbers I was able to do the calculations.
    Then I created a LibreCalc spreadsheet.
    Everything works just fine now.
    Except my plane, which is still in annual.
