MOBILE, Ala. — Continental Motors‘ IO-360-AF (alternative fuel) engine model has received type certification from the FAA.
The 6-cylinder IO360-AF is certified for standard 100LL as well as unleaded 91UL avgas now available in several countries. Flight Design is expected to take delivery of the first certified engine in the second quarter of the year for its four-seat aircraft, the C4.
The IO-360-AF is the first in its class to be certified for alternative fuels, benefitting markets where 100LL avgas is relatively expensive that also has 91UL available, according to company officials.
The lightest of all Continental’s six-cylinder aircraft powerplants, the IO-360-AF offers a maximum power output of 195 horsepower at 2800 RPM and a 2,200 hour Time Between Overhaul (TBO).
Flight Design will use the IO-360-AF engine de-rated to 180 horsepower as required for the C4, producing power at a reduced 2550 RPM, resulting in quieter operation, Continental officials noted.
