Diamond Eclipse Prop

I am a private pilot with 450hrs. Currently I own a grumman tiger and
have been looking to move into something newer. I have been looking at
the diamond c1 eclipse (2001-2002). Today I spoke to an A&P who informed
me of a strange phenomenon. One of the katana c1's at the flight school
had shed 2 props, one of them in flight! He said the sensenich prop was
wooden and that it expanded and contracted with the climate and could
loosen the prop bolts and therefore shed the prop in flight. The prop
bolts need to be retorqued every 50hrs and any time there is a
significant climate change.

Is anyone aware of this? If anyone owns an eclipse, I would love to hear
from you and perhaps speak with you before I make this purchase.

thanks
Scott
