Badwater Bill

My point is that, if at that time, two Lancair Legacies were flying in Australia and one of them crashed; then that would have been a 50% loss. However, it would have been a meaningless statistic--which, regrettably, is not uncommon. Therefore, I have enquired as to whether the data was statistically significant. Yep. Several homebuilt types have similar annual US fleet accident rates as Lancairs (examples: Velocity, RANS, Zenair) but the sample sizes vary so much that one or two accidents more or less can make a real difference. I suspect the Aussie fleet is quite a bit smaller. We also have to consider our definition of "Lancair." Is it fair to lump a Lancair Legacy with a Lancair IVP? Is it fair to lump a Lancair ES with the original Lancair O-235 (which had a REALLY small tail)? If you don't...then your sample size gets a lot smaller and your data is less reliable. How many of those ten Lancairs in Australia were Legacies? That said, the original two-seat Lancairs did have trouble getting certified in Australia, way back when. They used to require flight testing of homebuilts just like production aircraft, and the government test pilots rejected the Lancair due to its handling qualities. Ron Wanttaja |
