Ah yes, the unexplain "malfunction". I witnessed a guy take off in an R44 from a fairly remote Northern MN lake at 12:30 AM in low overcast and haze and watched him plow into the water no more than 200 yards off shore. He claimed an "unexplained" loss off power. Most of us call BS. His canopy was full of moisture and the horizon was barely distinguishable. He plain and simple flew into the lake. I suspect there is something more to this scenario than an "unexplained" pitch down. I find it hard to believe that the Zodiac 601 has a trim system, or autopilot for that matter, capable of generating enough of a nose down pitching moment to create enough force to punch a guy through the canopy. Not sure of any other malfunction that would result in a nose down pitching moment other than structural failure. I guess it wouldn't be the first time, http://www.eaa.org/n...2-25_zodiac.asp
