SMA Sporting The SR-305e Engine

By Dan Billingsley

Is an alternative engine in your future? SMA, a Subsidiary of the Safran Group would like to think so as they are showing the SR-305e here at Oshkosh. Geared for the general aviation market, this 4 stroke, boxer engine is designed to run on Jet A fuel and has already proven its dependability with an accumulated 30,000+ hours. They have been put through "real life" operating conditions throughout the world on 182 Skylanes, TB20s, Maules, and various other airframes. An STC was secured for the Skylane in 2003 for EASA and 2006 for FAA.

SMA SR 350 Engine

This is a turbocharged, direct injected, four cylinder engine that produces 230 hp at 2200 RPM. While burning Jet A, the engine will allow aircraft to reach 20,000 feet with a rated altitude at 10,000 feet. Climb rate is notably fast in reaching desired altitudes.

Luc Pelon

"This engine works for the needs of the GA world" says Luc Pelon, Chairman and CEO for Safran SMA. The primary point here was to bring to the forefront in everyone's mind that Av Gas and 100LL will not be around forever. While many are looking for an alternative fuel to use in the current worldwide fleet of aircraft, Pelon asks the question; "Why invest in the development of a new fuel when we already have a proven fuel that works?"

While this is somewhat a valid viewpoint, the question was asked about the cost of the SR-305e. A dollar amount was never given as Pelon talked about the long term savings. He indicated that if you are a pilot that files less than 40 hours per year, this engine should not be considered. The fuel or the engine is a question to ponder, however. If a new fuel breakthrough doesn't occur… what will you do?
