GREAT BARRINGTON, Mass.—When American Airlines pilot Kent Wien goes flying for enjoyable, his routine features a lengthy detour: a 90-mile round-trip flight from his base in Poughkeepsie, N.Y., to this city within the Berkshires to purchase unleaded aviation gasoline.
Lead was banished from U.S. gasoline 25 years in the past, however it’s nonetheless present in almost all avgas, the gasoline for a lot of propeller planes. Great Barrington’s small touchdown strip is the one airport wherever round that sells a lead-free various.
The restricted availability of unleaded avgas has till now stored Mr. Wien, who prefers unleaded and makes the journey just a few instances a month in his sporty two-seater, an outlier amongst pilots. Now, rising opposition from airport neighbors on each coasts could assist spur a broader transition away from leaded gasoline that has been in a holding sample for years.

How can the aviation business speed up the elimination of lead from avgas? Join the dialog under.
The battle has already caught up with pilots within the San Francisco Bay Area, the place Santa Clara County this 12 months banned the sale of leaded gasoline at two small airports. The airport in East Hampton, N.Y., which bustles with jet-setters over the summer time, has additionally thought of a ban.
If guidelines like these proliferate across the nation earlier than unleaded gasoline turns into extra extensively accessible, non-public flying—often known as normal aviation—may very well be badly damage, in line with the Aircraft Owners and Pilots Association, an advocacy group. “General aviation would really struggle if we lost our ecosystem of public-use airports supplying fuel,” its president, Mark Baker, stated.
Greg Spades, a flight-school supervisor at Reid-Hillview Airport in San Jose, Calif., stated the Santa Clara ban has added a whole lot of {dollars} in prices to a few of his firm’s classes. Its high-performance planes now should make journeys to different airports to refuel.
Mr. Spades stated the rule is onerous and looks like deliberate interference by politicians. “They knew it would severely impact our business,” Mr. Spades stated.
Total avgas consumption has tailed off over time, monitoring a broader decline in general-aviation flying. In the mid-Nineteen Eighties, airports pumped greater than 30,000 barrels of avgas a day. By final 12 months, consumption had fallen to about 12,000 barrels a day, in line with the federal Energy Information Administration. Airliners with jet engines, just like the
Airbus
fashions Mr. Wien flies at work, use a special unleaded gasoline.
Studies have linked air pollution attributable to leaded gasoline to continual sickness and developmental issues. In the Bay Area, a county-commissioned report discovered that banning lead from avgas would enhance childrens’ well being. For a lot the identical purpose, lead’s use in automotive gasoline started fading throughout the Nineteen Seventies and was lastly banned within the U.S. by the Clean Air Act in 1996.
“We’ve made it clear that we don’t sell leaded avgas, and it’s incumbent upon pilots to plan accordingly,” stated Sylvia Gallegos, a deputy county govt for Santa Clara. She stated the county is proud that its leaded-fuel ban has raised consciousness nationally.
Many pilots, too, are cautious of leaded gasoline. Mr. Wien hates getting it on his arms and believes leaded gasoline is worse for his aircraft’s engine and the atmosphere. But technical and enterprise challenges have confined the unleaded various he makes use of to a small area of interest.
Engineers have been working for years to develop an unleaded gasoline that burns easily in even essentially the most demanding aviation engines.
Adding result in gasoline boosts its octane ranking, which may help forestall combustion issues in some engines. Many high-performance propeller planes want a higher-octane formulation.
Two corporations, Swift Fuels and General Aviation Modifications Inc., are amongst these making an attempt to roll out options.
Swift’s 94-octane unleaded avgas is on faucet at about 70 small airports throughout the nation, together with the fields in California the place lead is now banned. Still, that could be a fraction of the greater than 5,000 public airports within the U.S., most of which nonetheless promote leaded avgas solely.
Expanding additional is gradual as a result of most airports don’t have spare tanks prepared for the unleaded product, stated Chris D’Acosta, Swift’s chief govt. And the gasoline doesn’t have a excessive sufficient octane ranking to interchange normal 100-octane avgas for high-performance planes.
Mr. D’Acosta stated the corporate is engaged on a 100-octane unleaded gasoline that may very well be prepared inside three years.
The Federal Aviation Administration has but to grant any such product its approval. Earlier this 12 months, the company launched a partnership with commerce teams and gasoline makers aimed toward what then-FAA Administrator
Steve Dickson
referred to as a “safe and practical path to lead-free aviation.” The group’s aim is to transition to lead-free gasoline by 2030.
Meanwhile, some unleaded fuels can work in some propeller planes. But even the place it’s accessible, getting pilots to just accept unleaded avgas is a problem.
On a current Saturday morning, Mr. Wien had little firm when he reached for the unleaded pump on the Great Barrington airport’s filling station. More just lately, a few of his flying buddies have made the swap, however shopping for unleaded nonetheless requires regulatory paperwork and a scavenger hunt for the few airports that promote it.
Pilot schooling is one other hurdle. Many have been taught that avgas comprises lead for good purpose, and nobody needs to experiment and threat a midflight engine failure.
“There are a lot of old-wives’ tales floating around,” stated Mike Busch, a mechanic and piston-engine professional. “Aviation is remarkable in the resistance to change, particularly on the maintenance side.”
