The FAA requires an experimental aircraft builder to keep a builders log to prove that they built the plane.
3/2/2006 - Crikey, now my wife's grandmother has died.
2/12/2006 - My wife's parents were killed in a fire, the project is on hold. Much more important things to worry about right now.
All due respect to the deaths in the family, but....does the FAA really CARE about that stuff?

Maybe a simple "Family issues, no time to work on aircraft"?
