Love the idea of a fully feathering prop, but I am afraid it ain't in
  the rage of affordable safety.
  It is insurance, but I doubt it is cheap insurance.
  Therefore, the next best thing is to set in place procedures which give
  the best option under extreme circumstances.

Dom,

I guess each of us looks differently at what is in the range of affordable
safety. If you look at the cost of  propellers for a TSIO-550, as listed on
the Lancair Web Site, you'll see the difference in cost of non feathering Vs
feathering is $1,170. I think that is cost effective.

Not to bring up bad memories, but when Shannon went down, I was prompted to
examine the prop issue with a view toward glide ratios. I bought a
feathering prop.

I hope Dave Morss will excuse me for this, but he feel strongly about this
subject. Dave told me, that after a few test flights in the Thunder Mustang,
he refused to make any more flights unless a feathering prop was installed.
After much wailing and gnashing of teeth one was installed. Shortly
thereafter, on take off, about 300 feet in the air, the engine quit. The
prop immediately feathered and Dave used that 300 feet to reverse course and
land on the runway from which he had just departed.

Had Dave not insisted on the change, he may not have survived the off
airport landing, but, certainly the Thunder Mustang program would have been
dead.

Yes, I'm convinced it is cheap insurance.

Regards,

Lynn
