“We have scheduled a mechanic to determine the cause of the leak coming from the left wing of the Baron, which should happen in the next few days,” AOPA senior vice president for media Kollin Stagnito told AVweb. “We are not yet sure what the substance is, nor where it is coming from.”

Word of the stains has been a hot topic on various forums, and speculation is rampant as to their cause.

GAMI chief engineer George Braly told AVweb the cause is most likely a faulty or improperly installed fuel cell bladder or patch inside the bladder. Braly said the bladders in the Baron may be more than 40 years old. He said G100UL has been tested for compatibility with the bladder material and there were no problems. He also added that fuel bladder leaks are a relatively common issue with Barons.

SAF is an alternative to conventional jet fuel designed to be more environmentally friendly than fossil fuel. Created from renewable resources, such as reclaimed cooking oil and feed stocks, it can reduce carbon emissions by up to 85 percent on a lifecycle basis, according to Neste. SAF can be used in unmodified aircraft engines and fuel delivery systems

United is a chief advocate for legislation to grow the SAF market. The airline has been instrumental in helping secure SAF tax credits in Illinois, as well as Washington, Colorado, and California that encourage airports to purchase SAF.

United is one of the founders of the SAF Coalition, which is described as a consortium of more than 40 airlines, aircraft operators, agricultural enterprises, aircraft and aircraft equipment manufacturers, airports, technology developers, labor unions, and biofuel producers. Its mission is to expand the use of SAF and reduce the reliance on fossil fuels.

In addition to Chicago, the airline has now purchased SAF for airports in Los Angeles, San Francisco, London, and Amsterdam.

“I’m pleased to see United Airlines making this significant move forward by using sustainable aviation fuel daily in flights from O’Hare,” U.S. Senator Tammy Duckworth (D-Ill.) said in a statement. “One of the most important things we can do to make American aviation more sustainable is increase the supply of SAF. At the federal level, I’ve been pushing for the increased use of SAF, and I’m going to keep pushing to increase the supply of American-grown, American-made SAF, a true win-win solution that supports domestic farmers and blenders while reducing our nation’s carbon footprint.”

Illinois Governor J.B. Pritzker echoed the enthusiasm, noting that KORD is one of the busiest hub airports in the United States.

“Illinois’ position as a hub of innovation with some of the most connected airports in the country perfectly aligns with the work of companies like United to build a more sustainable future for travel and reach our shared goal of zero emissions,” Pritzker said.

United Airlines president Brett Hart said tax incentives in Illinois made SAF availability at the airport possible.

“While the market for SAF is still in its infancy, there is a huge opportunity today for airlines and policymakers to work together to support its continued growth,” Hart said.

SAF purchased for United’s fleet is paid for in part through the company’s Eco-Skies Alliance, which allows participating companies to share the “green premium,” or the cost associated with purchasing lower-emission fuels. Since 2021, the alliance has collectively contributed toward the purchase of more than 10.5 million gallons of SAF, according to the company.

During the public comment period after formal presentations, Tim Roehl, president of General Aviation Modifications Inc. (GAMI), challenged a couple of points made during the presentations of members and support staff from the End Aviation Gasoline Lead Emissions. He told the crowd—smaller than in previous years—that contrary to assertions made during the formal part of the forum, GAMI’s G100UL is indeed ready for distribution and sale.

Eliminate Aviation Gasoline Lead Emissions (EAGLE) initiative member Pete Bunce, president of the General Aviation Manufacturers Association (GAMA), stood up and dismissed Roehl’s assertion.

“I totally disagree, but that’s a discussion for another day,” said Bunce.

In earlier comments, Bunce said his organization remains adamant that any new fuel will be approved through “transparency and a peer reviewed process,” which has traditionally been done through ASTM International.

“Transparency is so absolutely vital for us,” said Bunce.

Refiner Vitol Aviation has 1.3 million gallons of G100UL in tanks in Louisiana and says it has been completely vetted as ready for sale through its supplemental type certificate (STC). GAMI and Vitol have consistently said the FAA approval of an STC covering all gasoline engines on the agency’s registry satisfies all the regulatory and safety requirements to begin retail distribution of the fuel, but there are critics who contend it needs a consensus standard determined by an independent organization like ASTM to satisfy concerns about materials compatibility.

Aircraft Owners and Pilots Association (AOPA) president Mark Baker said his organization is using G100UL in a Beech Baron it operates and, based on the 200 hours of experience with the fuel, “GAMI is as good or better” than 100LL. He also said the process has to “move forward” to get the correct fuel.

The balance of the meeting was a reiteration of the stated goals of EAGLE, which increasingly has become focused on maintaining the supply of 100LL. The existence of the commercial quantity of G100UL has prompted politicians in California and Colorado to try to ban 100LL in favor of filling airport tanks with G100UL. Legislative and legal initiatives in both states are moving through their respective processes.

Meanwhile, testing of the last remaining candidate under the congressionally mandated Piston Aviation Fuel Initiative (PAFI) is slowly progressing at the FAA’s Atlantic City, New Jersey, test facility.

About 23 percent of materials compliance testing, 25 percent of durability testing, and a few percent of several other categories have been done on Lyondell/Basell/VP Racing’s entry. It’s also been fully tested on the airframe of a Lancair Legacy and on a Continental TSIO 550K engine.

SAF is made from sustainably sourced, 100 percent renewable waste and residue raw materials, such as used cooking oil, and feedstocks. Neste MY SAF meets ASTM D-1655 specification for conventional jet fuel and performance standards under all operating conditions.

Industry officials note this makes SAF an optimum solution for reducing greenhouse gas emissions from air travel without requiring new investments or modifications to aircraft or fuel infrastructure.

Embraer began using SAF in its operation at KMLB in 2021 when Avfuel would deliver one 8,000-gallon truckload of Neste MY SAF per quarter to Sheltair, the executive level FBO that supports Embraer operations.

• READ MORE: Boeing Ready to Buy 7.5 Million Gallons of SAF

“Sheltair is excited to support Embraer by handling and storing these SAF deliveries, ” said Leonel Rivera, senior vice president of FBO operations for Sheltair. “This collaboration between Sheltair, Embraer, and Avfuel shows our commitment to reaching the industry’s goal of net-zero carbon emissions by 2050. By combining our knowledge and resources, we will be able to handle and store weekly fuel deliveries of SAF.”

According to a statement from Embraer, the once-a-week delivery began in April. The extended partnership is expected to result in a total of 240,000 U.S. gallons of SAF delivered to Embraer in 2024, representing a significant increase when compared to previous years. According to the company, each truckload will provide a 19 metric ton reduction in carbon emissions, resulting in a 570 metric ton reduction in carbon emissions for the year.

With its fleet of business aircraft including the Phenom 100EX, Phenom 300E, and the Praetor 500 and the Praetor 600, Embraer has been serving the needs of the corporate traveling community for more than 50 years.

Oscar, well-known for his affinity for trash, has been dubbed United’s chief trash officer and is helping the airline educate the public about sustainable aviation fuel (SAF). 

SAF is made primarily of waste products, such as used cooking oil and agricultural waste feedstocks. According to United, it can be used in combination with conventional fuel in aircraft in accordance with current blending requirements, resulting in lower carbon dioxide emissions.

“SAF is one of the ways we’re planning to reduce our carbon footprint across United’s fleet,” the company said. “Investing in and using more SAF across the entire airline industry will help fly us all toward a lower carbon future.”

Since SAF is basically created from garbage, it made sense to have a trash expert like Oscar to be the company spokesperson for the effort.

United has several short videos starring Oscar the Grouch, beginning with one that shows how he saw a newspaper advertisement for a chief trash officer. With his 30-plus years of experience, how could he miss?

In other videos he plays opposite actual United employees who are excited about the use of SAF at the airline. He interacts with flight crews, sends junk mail to everyone in the world to let them know about United’s plans to power its airplanes on fuel made from waste materials. In another, he has a Zoom meeting with a Generation Z coworker with a sunny and upbeat disposition who wants to know how to spread the word that United is committed to lowering its carbon emissions by using SAF.

The campaign marks the latest SAF initiative for the airline. In February, Embraer announced it would join United Airlines Ventures’ Sustainable Flight Fund, an investment program aimed at increasing the supply of SAF through investment in related startup companies. The airline and its 22 corporate partners have committed more than $200 million to invest in companies working to decarbonize air travel.

“This is a transformative time for Signature, and our partnership with Neste is helping us take another significant step towards net zero by providing a 100 percent supply of blended SAF at our Los Angeles location,” said Derek DeCross, chief commercial officer at Signature Aviation. “This collaboration exemplifies how we’re working together with both our guests and our partners to accelerate the adoption of environmentally friendly practices and paving the way for a more sustainable future in aviation.”

• READ MORE: Boeing Ready to Buy 7.5 Million Gallons of SAF

The blended SAF offering provided by Signature at its LAX location includes 30 percent of Neste MY SAF and 70 percent conventional jet fuel, enabling partners to achieve a 24 percent decrease in greenhouse gas (GHG) emissions from air travel. SAF is approved for use blended up to 50 percent with conventional jet fuel.

Neste’s SAF is made from sustainably sourced, 100 percent renewable waste and residue raw materials, such as used cooking oil and animal fat waste. 

Signature and Neste have been in a partnership since 2020 designed to help accelerate the industry’s adoption of SAF. Signature plans to expand the availability of Neste MY SAF to the rest of its California locations. Neste is expanding its SAF production capability to 515 million gallons of SAF annually in 2024 to meet the growing demand.

Signature said it recently passed the 30 million-gallon mark in terms of total SAF delivered throughout its network, describing it as a substantial leap toward reducing carbon emissions and helping the aviation industry reach net zero by 2050.

• READ MORE: Business Aviation Industry Groups Aim to Speed Adoption of SAF

“We are proud to continue expanding our collaboration with committed partners like Signature Aviation, who recognize the key role sustainable aviation fuel can play in reducing GHG emissions from air travel,” said Carrie Song, senior vice president of commercial renewable products at Neste. “Offering blended Neste MY Sustainable Aviation Fuel to all of its customers at LAX is a shining example of how the business aviation community can work together with fuel producers to accelerate SAF adoption and emission reductions.”

The transition to SAF at KLAX was completed on April 1. It is the second location on the West Coast to offer the more environmentally friendly fuel. The first Signature location to provide SAF was San Francisco International Airport (KSFO).

In addition, the growth in SAF availability at Signature LAX will also expand the location’s role as a key component in Signature’s book-and-claim program. Under the program, travelers and operators are able to purchase SAF in areas where it isn’t physically available.

“When an operator utilizes book and claim, they are able to claim the environmental benefit, while the physical SAF is provided for different aircraft at Signature LAX,” Signature said.

The corn is now used to make ethanol, which is added to gasoline, but the move to electric cars will diminish that market. Ethanol can be turned into jet-A, however, and will cut the carbon footprint of jet fuel.

• READ MORE: Boeing Ready to Buy 7.5 Million Gallons of SAF

The administration is proposing subsidies from $1.25 to $1.75 a gallon for farmers but only if they meet some conditions.

The farmers will have to use “climate-smart” farming practices, including the use of approved fertilizers. The resulting fuel must cut greenhouse gas emissions by at least half compared to jet-A made from fossil fuels.

• READ MORE: Business Aviation Industry Groups Aim to Speed Adoption of SAF

The measures were met with approval from the farm community, but environmentalists are less enthusiastic. They are concerned a flood of ethanol-based SAF will hinder development of fuels that are even greener that the corn-based product.

In an online forum Tuesday, GAMA provided an industry update on the initiative to Eliminate Aviation Gasoline Lead Emissions, or EAGLE.

The forum included representatives from the FAA and GAMA.  Eric Blinderman, senior director of communications for the Aircraft Owners and Pilots Association (AOPA), acted as moderator, introducing the co-chairs of the EAGLE initiative that represent supply chain infrastructure and deployment; research, development and innovation; unleaded fuel evaluation and authorization; regulation policy; and programmatic activities.

• READ MORE: EAGLE Initiative Shows Measured Progress, Fuel Contenders Say at Oshkosh

Curt Castagna of the National Air Transportation Association (NATA) said fulfilling the EAGLE initiative will require a continued effort to educate users and other stakeholders— including the FAA—”to work as fast and as safely as we can.” Castagna said the goal is “to eliminate the use of leaded aviation fuels for piston engine aircraft in the United States by the end of 2030 without adversely impacting the general aviation fleet.”

Several speakers noted that the safety considerations and liability involved with the production of aviation fuel dictates that a considerable amount of testing be involved in the creation of unleaded (UL) products.

The UL100E unleaded fuel testing protocols include:

• Determining fuel compatibility with materials used in aviation, from the metal of the wings to fuel bladders, hoses, aircraft sealants, and elastomers.
• Determining engine performance for rated power as compared to the same engines running on 100LL and determining if detonation is a factor. The tests involve hundreds of engines. The impact of vibration of the aircraft propellers attached to those engines is also being studied.
• Determining the durability of the fuel and its effect on engine parts, especially testing for deposits that may form after hundreds of hours of operation.

The fuel tests will take place both on the ground and in the air under a variety of conditions, including cold soak and high temperatures and humidity.

The testing will involve multiple engines and multiple aircrafts. According to a graphic provided during the stakeholder meeting, this work has just begun, with the exception of the testing involving a Continental TSIO-550K.

“After testing, the engines are torn down to look for damage,” said Tim Owen, who has spent several years in product development at Continental Motors Inc. and been part of the Piston Aviation Fuels Initiative (PAFI).

Supply Chain

In addition to the development of a replacement fuel for 100LL, a seamless transition to UL fuel must also be developed. A support policy and regulatory proposal for maintaining 100LL availability is also needed, as are safety measures to prevent improper fueling during the transition.

Stakeholders noted during the meeting that many FBOs are already looking into means to accommodate both 100LL and UL fuels, such as acquiring a fuel truck for UL. In addition, there will be more training required for line crew and placards in aircraft to prevent accidental misfueling.

• READ MORE: The EAGLE Has Launched to Get Lead Out of Avgas

Discussions are underway with FBOs in remote areas, such as in Alaska, Hawaii, and Puerto Rico, to determine how fuel can be economically delivered to these locations.

It is still incumbent on the FAA to authorize the use of a new unleaded fuel in GA aircraft.

That can be done one of two ways: through the fleet authorization process established by Congress and in conjunction with the PAFI, or through the FAA’s traditional aircraft type certification/supplemental type certification (STC) process.

In March 2023, the FAA issued a Fleet Authorization Policy Statement, which describes the process to obtain a fleet authorization of a qualified unleaded fuel candidate.

“The FAA anticipates that approximately 68 percent of the [GA] fleet will be eligible to use UL 94/UL 91 fuels,” according to the EAGLE industry partnership.

Stakeholders also noted that the adoption of unleaded fuels will likely require extra placards on aircraft and extra pages in the pilot’s operating handbook (POH) to advise pilots of the changes, but that is likely years away.

The FAA is expected to issue a notice of proposed rulemaking (NPRM) and accept industry comments before EAGLE becomes law.
