Update:
I called this morning in hopes of finding out the status, and received an emailed quote back this afternoon. Their quote came in $1000 cheaper than my COPA insurance was in 2010.
Answering some questions before they come up:
1. Hull value, liability limits, number of seats, and deductibles, are all the same as my COPA coverage, with one exception i've been able to find: Baggage liability. COPA is $5000 per passenger, $100 deductible. EAA is $5000 total, no indication what the deductible is. I've asked the EAA insurer for a copy of the policy document to make a more complete comparison.
2. When I insured at the beginning of the year with COPA, I had a grand total of 10 hours of RV time, and about 325 hours total time. Renewing this year, i've put 50 hours on the RV in one year, and am now just under 400 hours total time. Maybe the lower rate reflects more experience with the plane?
3. There's no mention in EAA's coverage that i've seen (yet) about recreational aerobatics, nor formation flying, both of which are covered explicitly by COPA's Gold Wings package.
I'll update further if I get more info from the EAA provider.
