The City of Long Beach, California, is offering to pay piston aircraft operators to switch to unleaded fuel. Last week the city council of the Los Angeles suburb voted to have the city cover the $2-$4 per gallon difference between Swift Fuels and 100LL. In November, the city council voted to cover the cost of the STC needed for aircraft to legally use the fuel up to $300. Swift sells the STC for $100. The unleaded fuel has been at the Signature FBO at Long Beach since last August but hadn’t been selling well because it’s more expensive than standard avgas, so the city council stepped in. The $300,000 budget will come from airport operating revenues.
