UL 91 Avgas
Posted: Mon Oct 01, 2012 9:06 am
I missed this earlier in the year. http://www.generalaviationnews.com/2012 ... ded-avgas/. Notable is that all the engines for the 235 hp Maules and possibly the 260hp (V series) are going to be included. (The 360 series were already covered.)
"The latest models to be approved include the large installed base of (I)O- 320-B, D; LIO-320-B; O-540-A, D, E, F, G, H, J; and IO-540-C, D, N, T, V, W, AF, AB engine models"
An almost comical statement from the Lycoming spokesperson; "If your engine is approved on this fuel then your airframe is automatically approved ... in the EU. In the U.S., if the engine is approved, you may still need approval for the airframe."
A bit of common sense prevailing in the US and not Europe for a change.
SO...where and when does someone go about buying ASTM D7547 UL 91 unleaded avgas in the US. Looks like it is on market in the EU. Just have to make sure your airframe is approved. As far as I know it isn't available in the US yet. Anyone know differently?
