 Far be it from me to tell others how to manage their own risk. As for me, I
 thought about all of this a long time ago, when flutter first came to the
 fore as a possible cause of the breakups. I see no particular reason to
 change my thinking now.
 
 I plan to keep flying my Zodiac unless and until the FAA or AMD issue orders
 to ground the aircraft. I do keep on top of my aileron cable tensions per
 the AMD service bulletin - though the NTSB letters reveal those tensions
 were developed on the CH2000 Alarus, not the Zodiac - and make sure there's
 tension on the cables during preflight; keep the airspeed within the green
 arc unless the air's absolutely glass smooth; and slow to maneuvering speed
 in anything more than slight turbulence. I believe these steps will minimize
 the risk of flutter until a permanent fix can be found.
 
 That fix is likely to be aileron mass balances. Every aeronautical engineer
 I've discussed the issue with has expressed surprise at the Zodiac's
 approach to flutter prevention, and said that it wouldn't likely be
 considered acceptable.
 
 Life is risk. Aviation is all about managing risk. Yes, I could die in my
 airplane tomorrow. I'm more likely to do it by doing something stupid that
 kills lots of pilots, rather than by having my airplane come apart around
 me. I'm even more likely to die in my car on the way to the airport, or in
 bed, or lots of other ways. I do what I can to manage risk, and then I quit
 worrying about it.
