Background to the development of the Swift 100R
Swift Fuels, a US company with its registered office in West Lafayette, IndianaAfter around 15 years of research, the first Supplemental Type Certificate (STC) for the unleaded avgas fuel Swift 100R received. The suffix "R" in the name stands for Renewablewhich emphasises the intention to increasingly rely on renewable energies and environmentally friendly fuels in aviation. The fuel is too ten per cent is made from renewable components and is completely free of the toxic lead additive tetraethyl lead (TEL), which is used in Avgas 100LL.
The approval of Swift 100R represents a lead-free alternative for the avgas types used in many aircraft and thus offers a solution to the impending ban on avgas 100LL in Europe. A similar step was already taken in 2021 with the FAA approval of GAMI G100ULanother lead-free aviation fuel. Swift 100R now offers another option to meet the requirements of the future.
Technical details and advantages of the Swift 100R
Like the conventional Avgas 100LL, the new Swift 100R fuel has a Number of motor octaves from 100which means that it can be operated under the same conditions as leaded avgas. This is a decisive advantage, as no extensive modifications to the engines or the airframe are necessary. According to Swift Fuels, the new fuel is also compatible with already approved avgas grades. misciblewhich makes it easy to switch to the new fuel.
In addition, Swift Fuels emphasises that no damage to aircraft surfaces is to be expected if the fuel is used improperly. This is a further safety advantage over conventional avgas. However, before using Swift 100R, aircraft owners must complete an individual Release for your aircraft to ensure that the specific requirements of your aircraft are met.
Future plans and international expansion
Swift Fuels is already working closely with the FAA to Other engines and aircraft models for the use of Swift 100R. The aim is to publish a Approved Model List (AML)which lists all aircraft that can use the fuel without modifications. This is an important step towards making the fuel more widely usable throughout general aviation.
The next challenge now is to ensure that the European Aviation Safety Agency EASA also recognises the approval of the fuel. This process is already underway and it is expected that Swift 100R will soon be available for use in Europe. In Europe, Swift Fuels is recognised by the German limited liability company based in Saarbrücken, headed by the chemist and pilot Dr Thomas Albuzat. Distribution in Europe is handled by Bollinger Aviation a company based in Egelsbach and Oberursel.
Challenges for the future of aviation fuels
The introduction of unleaded alternatives such as Swift 100R is becoming increasingly urgent as the future of leaded avgas in the EU is increasingly in doubt. As early as April 2022, the EU Commission a change in the REACH Regulation which regulates the handling of hazardous chemicals. A central topic of this regulation is the ban on Tetraethyl lead (TEL)one of the main components of leaded avgas. This ban is to take effect from 1 May 2025 would come into force, which would make the production of Avgas 100LL illegal in the EU.
While some avgas manufacturers have applied for exemptions, it is still unclear whether these will be approved by the EU. This means that general aviation in Europe faces an uncertain future when it comes to the availability of fuels.
Another problem that Bollinger Aviation emphasises concerns the EU Regulation 1907/2006, which private users of aviation fuels additional hurdles. In addition to the ban on lead, the use of Cumeneanother chemical found in some aviation fuels, is affected by regulation. The introduction of Swift 100R could solve these problems and provide a greener, safer and long-term option for general aviation.
Conclusion: A path to a lead-free future
The approval of Swift 100R for the Cessna 172 R and S by the FAA marks a decisive step towards more environmentally friendly and sustainable aviation. While unleaded fuels are becoming increasingly important and the use of Avgas 100LL will soon be restricted, Swift 100R offers a practical alternative for pilots and aircraft owners. However, it remains to be seen how quickly these and other lead-free fuels will become established in Europe and what regulatory hurdles still need to be overcome. One thing is clear: the transition to lead-free alternatives is not only ecologically necessary, but also unavoidable in order to lead general aviation into the future.
