Converting the 172 Skyhawk

Conduct your flight training in a Skyhawk 172 retrofitted with a Continental Aerospace Technologies GmbH Diesel Engine and significantly reduce your operating costs. With over 60 retrofits to date, Africair, Inc. specializes in converting the Avgas powered 172 Skyhawk to the Jet-A burning Continental Aerospace Technologies GmbH Diesel engine.

Benefits of the Diesel Engine Conversion

  • Less fuel consumption, significantly reducing operational costs.
  • Jet-A is readily available most anywhere in the world unlike costly and scarce Avgas.
  • Continental Aerospace Technologies GmbH Diesel engines have logged over 3 million flight hours.
  • The 155hp CD-155 & 135hp CD-135 engines are turbocharged.
  • At high elevation airfields, the Continental Diesel engines outperform 160hp Avgas engines.

Continental Aerospace Technologies GMBH CD-135 Engine

Continental Aerospace Technologies GmbH offers with CD-135 a jet fuel piston engine for general aviation with a take off power of 99 kW (135 hp). The CD-135 is a turbo charged 4-cylinder in-line engine which is EASA certified since August 2006 and FAA certified since October 2006.

The CD-135 is certified for the use of both jet fuel and diesel (DIN EN590) and is running with the two fuels in any mixture ratio. The engine has a time between replacement (TBR) of 1,500 hrs.
