According to Saint Loup, a fuel consumption rule-of-thumb for this engine is approximately 5 gallons per 100 horsepower. “The maximum full power fuel consumption at sea level on an ISA standard day is 12.2 gallons per hour which is approximately half the fuel flow of the turbocharged engine it replaces,” says Saint Loup. This translates into big advances in range. Saint Loup cites figures showing that the SMA engine will beat the avgas engine in the T182T by 65 percent in range if both engines are flown at extremely high power (90 percent power setting). At more normal cruise power settings the number is around 40 percent.
Cessna should be applauded for bringing the Skylane JT-A to market. Small airplanes have always been vital in the growth of commerce. A “kerosene” burning airplane such as the Skylane JT-A will be the seed that sprouts small commercial aircraft service in countries that lack the avgas distribution and availability enjoyed by U.S. owners and operators.
Required maintenance plan
The SMA SR305-230E-C1 engine in the Cessna Skylane JT-A does present new maintenance challenges to A&P technicians. The Type Certificate Data Sheet (TCDS) is under Societe de Motorisation Aeronautiques.
1. Run up engine with laptop computer connected and record ECU data.
2. Change engine oil and filter.
3. Pull magnetic plug in sump check for metal — pictures in maintenance manual illustrate maximum allowable metal
4. Inspect oil filter — it’s not a spin on, you can’t cut it apart but the folds of the screen material can be spread for inspection and it can be back flushed into a coffee filter or paper towel.
