No endorsement required for the 207-900, but you need a twin endorsement for the 207-900T which is, you guessed it, the twin engine version. It has two IO 470s up front, one behind the other. The rear one drives by 2 gears to a shaft over the top of both engines, which turns a left handed prop (the gears reverse direction of rotation), and the forward engine uses a hy-vo chain to drive a hollow shaft concentric with the other. This has a right handed prop just behind the LH one, so you end up with contra-rotating props and no P-factor to worry about. The beauty of it is, you can shut down the front engine (NB. it drives the
rear prop!) in the cruise, feather the prop, and get really good fuel burn figures. To re-start is simplicity itself, you just un-feather the rear prop and the wash from the front one spins the engine up! This is known to old -900T drivers as "getting a blow job!"
We didn't get the S.N.A.K.E. Certificate as it was a lot of paperwork for just a one-off job, and we were only
importing.
Cheers, Sailing.
