Dear Hartzell/550 owners,
If this email looks garbled to you, set
your window as wide as you can.
We've been having this discussion about a
possible vibration problem but we haven't accumulated much data on
the incidence of the problem or especially
the incidence of a non-problem. To help us sort it out it would be
super helpful if everybody that has the
550/Hartzell combination could please add your information below.
It is just as important to send your info
if you DON't have a problem.
(Please use the fixed width font and spaces
not tabs). I volunteer to collect all the responses and publish
the result. If you would like to be
anonymous you can send your information directly to me and I will remove
We have 1000 lancairs or so we think are
flying and several hundred IV's with the 76" prop. It would be great to
get a couple hundred responses. It would
help even more if we could get this before or early into Oshkosh week.
thanks in advance,
Colyn
