I've got only 16 accidents (1998 through 2014, inclusive) involving Team aircraft, including Mini-Max, Z-Max, and Hi-Max. No cases of structural failure, no cases of builder error. Pilot Miscontrol is a bit higher than average (47% vs. 38% overall) but the small sample size may be skewing the result. No other causes stand out.
Remember, though, my records are only for N-Numbered aircraft. It doesn't include any examples operated as Part 103.
