FAA approves unleaded fuel for piston fleet

The FAA signed on September 1 supplemental type certificates that allow General Aviation Modifications Inc.’s 100-octane unleaded fuel (G100UL) to be used in every general aviation spark-ignition engine and every airframe powered by those engines. The move was hailed by the industry as a major step in the transition to an unleaded GA future. The FAA’s approval of the use of G100UL fuel in all piston aircraft satisfies a longstanding goal of finding a solution that can be used for the entire GA piston fleet.

“I’m proud of GAMI, the industry team, and the FAA for persevering over the long term and getting a fuel that the FAA has recognized as a viable alternative to low lead,” AOPA President Mark Baker said. “It’s vital that we find solutions to what has been plaguing general aviation since the seventies. It’s certainly the biggest issue I have dealt with in my time at AOPA. This is a big deal,” Baker added, “but there is a lot of work yet to be done.”

In 2021 the FAA approved STCs for GAMI covering a smaller number of Cessna 172 engines and airframes, and then expanded the approved model lists (AML) to include essentially all lower-compression engine and airframe combinations. Though that was seen as an encouraging step forward in the yearslong path to supply unleaded aviation fuel to the piston aircraft fleet, the STCs did not include aircraft needing the higher-octane fuel that accounts for 60 to 70 per cent of avgas consumption. This latest announcement by the FAA addresses the needs of those higher-compression engines.

GAMI cofounder George Braly said, “This is a big day for the industry. It means that for a lot of our general aviation communities, and especially for a high fraction on the West Coast, relief is on the way. And it means that our industry will be able to go into the future and prosper, and provide the essential infrastructure for this country for everything from Angel Flights to critical training of our future airline pilots.” Braly thanked AOPA and the GA community for their support through this long process. “Without it we couldn’t have gotten this done,” he said. Braly has said that Ann Arbor, Michigan-based fuel supplier Avfuel is standing by to manage the logistics and distribution of G100UL, and said he is open to partnerships. “Our arrangement is that any qualified refiner or blender of existing aviation fuels will be eligible to produce and sell it subject to the quality assurance requirements that the FAA has approved,” he said.

When will G100UL reach airports and aircraft tanks?
The timing for when G100UL will reach airports is still uncertain. “It’s going to take a while to manage the infrastructure” including manufacturing and distribution, Braly said. The supply chain “is still a very wounded infrastructure and that’s not going to make the process any easier, but we have a handle on how to do this, and with the support of the major players I think we can do that. It’s going to be limited, to begin with, but it can be ramped up rapidly,” he said. Baker said it’s important to get any fuels approved for use in the California market as soon as practical, in light of the fact that some municipalities have prematurely banned the sale of leaded avgas and threatened a safe and smart transition to unleaded fuel. “It is a politically charged issue there, and this will help keep our airports open with fuel that works with all aircraft.” AOPA will also purchase a number of unleaded fuels to use in its fleet of piston aircraft used for GA travel and flight training, showing members it has full confidence in FAA approval pathways and processes.

What will G100UL cost?
While the cost of the fuel has not been determined, Braly said the small-batch production process that will initially earmark the arrival of G100UL at airports means that the fuel will cost slightly more than leaded avgas. “Small volume batches cost money,” he said. “Until we can get [production] revved up that we’re making millions of gallons at a time, there will be an incremental [additional] cost,” he said. “It’s not going to be unreasonable,” he said. “Pilots in America will not be paying what they’re paying for avgas in Europe today.” And while they may pay a little more at the pump, owners can expect to see engines that operate more efficiently. “I think the days of cleaning spark plugs every 50 hours are going to be behind us for good,” Braly said.

Swift Fuels Inc., an Indiana-based company, has received FAA approval for its 94-octane unleaded fuel and has expanded its distribution, particularly to the West Coast. Swift Fuels’ 94-octane fuel meets some, but not all, of the demand of aircraft with low-compression engines. The company is developing a 100R unleaded fuel with more than 10 per cent renewable content. In addition, two fuel candidates are currently in the Piston Aviation Fuels Initiative testing process. AOPA continues to encourage all fuel manufacturers to follow through with their own formulations, Baker said. “We’d like to see several fuels available that all work together and blend together. Competition is always a good thing for the markets.” Source: ‘AOPA‘.

FAA ermittelt gegen Harrison Ford

Nach einem Zwischenfall auf einem kalifornischen Flugplatz ermittelt die US-Flugaufsichtsbehörde FAA gegen Hollywoodstar Harrison Ford. Die Maschine des Schauspielers überquerte eine Start- und Landebahn, auf der ein anderes Flugzeug gerade das Landen mit sofortigem Wieder-Durchstarten übte, wie die FAA am Mittwoch erklärte. Der 77-jährige Star aus Filmen wie „Indiana Jones“ und „Star Wars“ war vom Tower aufgefordert worden zu halten, hatte die Ansage aber offenbar falsch verstanden. „Entschuldigen Sie, Sir, ich dachte genau das Gegenteil. Es tut mir furchtbar leid“, sagt der Schauspieler in einem aufgezeichneten Funkspruch. Beide Maschinen waren bei dem Zwischenfall auf einem Flugplatz im Landkreis Los Angeles am Freitag rund einen Kilometer voneinander entfernt, niemand kam zu Schaden. Ein Sprecher des Schauspielers sagte der Nachrichtenagentur AFP, bei dem Vorfall habe „zu keiner Zeit die Gefahr eines Zusammenstoßes“ bestanden. Es ist nicht das erste Mal, dass der begeisterte Pilot Ford Ärger wegen seines Hobbys hat. 2017 entging er knapp einer Strafe, nachdem er auf einem anderen kalifornischen Flughafen die Lande- mit einer Rollbahn verwechselt hatte und mit seinem Kleinflugzeug dicht über eine Boeing 737 mit 116 Insassen hinweggeflogen war. Zwei Jahre zuvor musste er mit einem Oldtimer-Flugzeug nach einem Triebwerksausfall auf einem Golfplatz notlanden und erlitt dabei mehrere Knochenbrüche. Quelle: ‘Stuttgarter Zeitung‘.

FAA Warns Customers Away From Aircraft Ride Share Apps

The FAA is warning potential customers of aviation ride sharing apps likened to “Uber for airplanes,” that their trip might not meet the normal standards for fly-for-hire journeys. “If you pay for a charter flight you are entitled to a higher level of safety than is required from a free flight from a friend,” the agency said in an unusually pointed public statement. “Among other things, pilots who transport paying passengers must have the required qualifications and training, are subject to random drug and alcohol testing, and the aircraft used must be maintained to the high standards that the FAA’s charter regulations require.” At the same time it sent a letter to San Francisco-based BlackBird saying that its pilots must meet the terms of Part 119 operations. Throughout its website promotion material and its legal fine print, BlackBird insists that it is not an air carrier by matching passengers with available seats or aircraft. The FAA isn’t buying it, however, particularly when it comes to its stable of pilots. “We have little trouble concluding that the pilots listed on BlackBird’s pilot database selected by the user are transporting persons or property, from place to place, for compensation. Despite BlackBird’s assertion that the pilots are not transporting persons or property, it is clear that they are being hired for that very purpose.” BlackBird did not immediately respond to an email request for comment and its website remains active.

Zivile Drohnen für die Luftfahrt keine Gefahr.

Wissenschaftler der George Mason University haben das Risiko, welches von zivilen Drohnen für die Luftfahrt ausgeht, untersucht. Das Ergebnis: Statistisch ist das Risiko so gering, dass es nur einmal in 187 Millionen Jahren Flugzeit zu einem tödlichen Unfall kommt. Die Wissenschaftler haben für ihre Berechnung durch die US-Flugaufsichtsbehörde FAA gemeldete Vogelschläge der letzten 25 Jahre ausgewertet. Diese wurden ins Verhältnis zu den etwa zehn Milliarden Vögeln in den USA gesetzt. Zudem wurde berücksichtig, dass nicht jeder Vogelzusammenstoß zu Schäden am Flugzeug oder gar zu einem Absturz führt. Die FAA registrierte in den vergangenen 25 Jahren 160.000 Kollisionen mit Tieren – davon waren lediglich 14.000 Zusammenstöße, die zu einer Beschädigung des Flugzeuges führten. Bisher ist nur ein einziges Mal ein Passagierflugzeug durch einen Vogelschlag verunglückt. Dies geschah im Jahr 2009, wo der US-Airways-Flug 1549 im Hudson River in New York notwassern musste. Die Zahlen zeigen zudem, dass es in den letzten 25 Jahren in den USA nur zwölf Zusammenstöße mit Flugzeugen und Tieren (Vögel, Hirsche, etc.) gab, bei denen Menschen starben.
