    I don't want to get anybody upset or into a MY PLANE IS this & that war. This is Just the Facts, Mam', Just the Facts.

    Also, I don't have a dog in this fight.


    I was remarking to my CFI the other night that there seemed to be alot more Piper accidents for the number of planes built, compared to Cessna. (single engine piston) All I had at the time was anecdotal evidence. Well after a couple of hours of digging and adding from the FAA database, I now have proof.

    While you wait with baited breath for my all inspiring report, let me tell you the good news. Accidents & deaths per year are down significantly every decade for both, and GA in general.

    Piper has listed 50,213 single piston engine aircraft total.
    Cessna has 74,843, a 49% increase over Piper. This is my baseline for comparison.


    Deaths
    Decade:______Piper________Cessna
    70's_________ 1854________ 2196
    80's_________ 1318________ 1858
    90's__________ 905________ 1247
    00's__________ 549_________ 850

    Total:______4,626_______6,151

    Cessna increased only 33% VS. a 49% baseline.

    Accidents
    Decade:_____Piper_____Cessna
    70's_______10,474_____15,784
    80's________6,462_____11,624
    90's________4,087______7,585
    00's________2,444______4,579

    Total:____23,467____29,572

    Cessna increased only 26% VS. a 49% baseline.

    Basically, you have a 16% greater chance of dying in a Piper, and a 23% greater chance of being in an accident.

    My numbers are off slightly because I forgot to include the last 20 days of December in each decade, but since I did it to both the numbers hold up.

    I don't have a dog in this fight either, but I do have a major question. Doesn't your analysis assume that al Piper and Cessna single engine aircraft fly equal hours per year. In other words, what if the Piper fleet flys twice as many hours per aircraft than the Cessna fleet - doesn't that give you the opposite conclusion?

    Is there data for flight hours instead of just numbers of aircraft? How about even airworthy aircraft during the given statistical year?

    No dog here either, but ......

    Cessna and Piper, sell the same number of aircraft too??? and there is exactly the same number of each on the tarmac??

    Trouble with "The Facts, just the facts" is....
    "The Facts", can be made to report whatever the statistician wants them to.

    Careful now guy's .....
    We may be accused of just not wanting to hear the truth...

    At least that's what the statisticians say.... ;- )

    Considering how much more Cessna is flown for training (instruction and solo) and <100 hour pilots I find that a significant point.

    I did all my training in a Piper.

    I say there aren't enough facts in those facts.

    I'd like to know how many of those accidents are "pilot error" as opposed to something actually being wrong with the plane.

    The big question, if we accept the statistics at face value (always a dangerous thing to do), is _why_ the rates may be different.
