This flight is important because it shows that airports and operators in the Benelux are ready to adopt new, safer fuels. Swift 100R is designed to replace the old leaded Avgas 100LL, which has been used for decades but is now seen as a risk to people and the planet. The move is part of a wider push in Europe and around the world to get rid of lead in aviation.
What Is Swift 100R Fuel?
Swift 100R is a new type of aviation gasoline (avgas) made by Swift Fuels, a company based in the United States 🇺🇸. Unlike traditional avgas, which contains lead, Swift 100R is completely unleaded. It has a high octane rating (100), which means it can be used in many types of piston-powered aircraft, including those that need more powerful fuel.
Key features of Swift 100R:
– Unleaded: No lead, making it safer for people and the environment
– High-octane: Suitable for many aircraft engines that need strong fuel
– Direct replacement: Designed to be used instead of Avgas 100LL, with no major changes needed for approved aircraft
Current Status: Who Can Use Swift 100R?
Right now, Swift 100R is not available everywhere. It’s only allowed for use in certain aircraft that have received special approval from the Federal Aviation Administration (FAA) in the United States 🇺🇸. This approval is called a Supplemental Type Certificate (STC). Only aircraft and engine combinations listed in the STC can use Swift 100R, and only at airports that are part of the restricted rollout, like Antwerp Airport.
Certification and Regulatory Details:
– FAA STC Approval: As of September 6, 2024, Swift 100R is approved for Cessna 172 Skyhawk models R and S with Lycoming IO-360-L2A engines.
– ASTM International: The fuel is still being reviewed by ASTM International, which sets global standards for aviation fuels. Full approval is expected in 2025.
– Restricted Use: Only aircraft with the right STC can use Swift 100R, and only at certain airports.
For more information about FAA certifications and the STC process, you can visit the official FAA website.
Why Is This Change Happening?
The main reason for switching to Swift 100R is to get rid of lead in aviation fuel. Leaded avgas, like 100LL, has been linked to health problems, especially for children living near airports. It also harms the environment by polluting air and soil. Many countries have already banned lead in car fuel, but small airplanes have been one of the last places where lead is still used.
Benefits of Swift 100R:
– No lead emissions: Protects people’s health and the environment
– Meets high engine needs: Works in many powerful aircraft engines
– Supports global goals: Helps countries meet their promises to reduce pollution
Who Is Involved?
Several important groups are part of this change:
- Antwerp Airport: Hosting the first Benelux flight with Swift 100R, showing leadership in green aviation.
- Styl Aviation: Operated the first flight, helping test and prove the new fuel.
- Swift Fuels: The company that makes and supplies Swift 100R. Their CEO, Chris d’Acosta, believes 2025 will be the year Swift 100R becomes the main unleaded avgas.
- FAA and ASTM International: These organizations make sure the fuel is safe and works well in many types of aircraft.
As reported by VisaVerge.com, Swift Fuels is the only company right now working to get both FAA and ASTM approval for a 100-octane unleaded avgas, which is needed for wide use in the aviation industry.
How Does This Affect Aircraft Owners and Operators?
If you own or operate a small airplane, this change could affect you soon. Here’s what you need to know:
Step-by-Step: Using Swift 100R
- Check if your aircraft is eligible: Only certain aircraft and engines are approved for Swift 100R. You need to check the FAA STC list to see if yours is included.
- Register for use: Some airports may require you to register your aircraft before you can use Swift 100R.
- Follow fueling rules: Use the fuel only at approved airports and follow all safety instructions.
- Monitor your flights: Keep track of how your aircraft performs and report any problems. This helps with future approvals and safety.
What If Your Aircraft Isn’t Approved Yet?
If your aircraft isn’t on the approved list, you’ll need to wait until Swift Fuels and the FAA expand the STC to cover more models. Swift Fuels plans to add more aircraft, including turbocharged engines and piston helicopters, throughout 2025.
What Does This Mean for Airports and Fuel Suppliers?
Airports like Antwerp Airport are leading the way by offering Swift 100R. But this also means they need to make changes:
- Fuel storage: Airports may need new tanks or equipment to handle the new fuel safely.
- Training: Staff must learn how to handle and store Swift 100R.
- Inventory changes: Fuel suppliers will need to adjust their supply chains as more airports switch to unleaded avgas.
The Bigger Picture: Environmental and Health Benefits
Switching to Swift 100R is about more than just airplanes. It’s a big step for public health and the environment:
- No more lead pollution: Lead from avgas can get into the air, soil, and water, causing health problems, especially for children.
- Cleaner air: Removing lead means cleaner air around airports and in nearby communities.
- Supports climate goals: Many countries, including those in the Benelux, have promised to cut pollution. Switching to unleaded fuel helps meet these goals.
What’s Next? The Road to Full Approval
Swift 100R is currently only available on a restricted basis, but this is expected to change soon. Here’s what’s coming:
- ASTM International Approval: Full approval is expected in 2025. This will allow Swift 100R to be sold more widely.
- More aircraft approved: Swift Fuels plans to get approval for more types of aircraft, making the fuel available to more pilots.
- Market expansion: As more airports and aircraft switch to Swift 100R, it could become the standard fuel, replacing both UL94 and 100LL.
How Many Aircraft Could Benefit?
There are over 225,000 piston-powered aircraft in the United States 🇺🇸 alone that could eventually use unleaded avgas like Swift 100R. Swift Fuels aims for 100R to be usable by 75% of the piston-powered fleet by the end of 2025.
What About Competing Fuels?
Other companies are also working on unleaded avgas, like General Aviation Modifications Inc. (GAMI) with G100UL and LyondellBasell/VP Racing Fuels with UL100E. However, these fuels have not reached the same level of regulatory approval or industry support as Swift 100R.
What Do Stakeholders Say?
Airport Operators:
They see this change as a way to reduce pollution and get ready for future rules that may ban leaded fuel.
Aircraft Owners:
Many are happy about the move away from lead, but some worry about how long it will take for their aircraft to be approved and whether the new fuel will be easy to find.
Fuel Suppliers:
They need to plan for new storage and delivery systems as more airports switch to Swift 100R.
Regulators:
They stress the need for careful testing and agreement on standards to make sure the new fuel is safe for everyone.
Background: Why Was Lead Used in Aviation Fuel?
Leaded avgas was first used because it helped prevent engine knocking (a type of engine problem) and allowed engines to run at higher power. But over time, the dangers of lead became clear. Lead is a poison that can cause serious health problems, especially in children. Most car fuels have been unleaded for years, but small airplanes have been slower to change because they need high-octane fuel.
Swift Fuels first introduced UL94, an unleaded avgas for less powerful engines. Now, with Swift 100R, they are targeting more powerful engines, which make up a large part of the general aviation fleet.
