We orderd the throttel from Webco and there is no trouble with putting

the log book. DONE go fly(hs and IA also)



Yes, I don't even remember anything about the paperwork. It was a
non-event for me, the owner. The shop took care of everything, and had
no trouble with the FAA doing it.

Where are you located? I need a new shop to work on my airplane, and I
saw in one of your earlier posts that yours "does lots of Comanches".
That makes a difference.
