they all must be fungible with one
another. This fungibility (mixable) issue is
an important one and should be addressed
as fuel testing goes forward. Ultimately,
the market will determine how many fuels
can realistically compete in this space.
Moreover, most airports in the U.S. do
In short, the STC process is proprietary
by its very nature, and engine manufactures
and fuel distributors simply want to
learn more about the GAMI fuel. Although
there is no legal requirement for GAMI to
pursue an ASTM fuel specification, some
suggest it should do so. And while GAMI
has reported incorporating many ASTM
testing standards in pursuit of its FAA STC
approval, it remains hesitant to go through
such a cumbersome and complicated process
that could take years. I believe having
some type of industry consensus, not necessarily
an ASTM standard, would be very
helpful in moving the GAMI fuel forward.
Swift has also pursued the STC pathway
with its 100R unleaded fuel and is
seeking an ASTM specification. Swift has
indicated that it may receive FAA approval
for its fuel by the end of this year.

Whether through the STC process,

some type of industry consensus, any

not have the financial wherewithal to add
additional fuel tanks (or trucks). And for
those that do, there can be confusion in
having multiple tanks with multiple fuels
that may or may not mix with each other.
We at AOPA have been advocating
for a program that would provide
an opportunity for any FAA-approved
100-octane unleaded fuel to be demonstrated
in a way to help build industry
confidence. The demonstrations will
produce data on whether the fuel(s) will
reduce engine maintenance or any have
impact on spark plug fouling, valves, and
engine oil, and I am pleased the FAA has
agreed to make significant funds available
for this very purpose.
The EPA endangerment finding,
expected to be released in October, will
require the removal of lead from fuel,
something we've been focused on for
years. But please don't panic-100LL will
remain available at airports during this
transition. This endangerment finding
kicks off a regulatory process that will
require the FAA to develop a path forward
for removing lead from avgas.
I have the privilege of co-chairing
a government-industry partnership
called Eliminate Aviation Gasoline Lead
Emissions (EAGLE) that will be involved
in helping develop these regulations. At
the same time, it is important to reaffirm
the role of EAGLE: It's not to make fuel,
not to approve fuel, but rather to facilitate
information and communication among
those involved in the safe transition to
replace 100LL.
AOPA is working every day with a
sense of urgency. It will take the FAA,
fuel companies, engine manufacturers,
fuel distributors, FBOs, and every other
party in this issue to attain our safe and
smart transition to unleaded fuel by 2030.
I say, let's get this done as quickly and as
safely as possible.
