'Plotting the percentage of accidents versus the aircraft total time (Figure 3) produces some interesting results. About 6.2% of all homebuilt accidents occur on the first flight. About 19% of the total accidents occur before completion of the nominal 40-hour test period (which can be less for some aircraft)'

'the overall accident rate for U.S.-registered aircraft is about 0.61% per year, while the homebuilt rate is 0.87%. In other words, the homebuilt accident rate is about 44% higher.'

'But the most arresting result: Almost one quarter of first-flight accidents are due to builder error! Finally, see how close the four categories are in the Pilot Error–Failure to Control category. Yes, it’s a bit higher early on, but it stays surprisingly close to the percentage of the overall fleet.'

It was indeed. I'm pretty darn sure it was a Murphy Moose with an Allison 250 in it. They are highly regarded and well engineered. IIRC, the chief designer for Murphy was an ex-deHavilland engineer.
