The place i rent from has a Duchess, and they require 250TT, Commercial and Instrument rating, and 25 multi. No make and model requirement. One of the neat things is the fact that since we have a Dir. of Ops, and such, our insurance company allows our FLight School manager to waive any of the HOURLY requirements. I got my Multi-Commercial yesterday, and i have like 11.5 multi, and i am allowed to fly it. We used to have a Be-58 that required 500TT, 150 Multi, 15 Make and Model, as well as a 340 with the same requirements.
