The FAA issued an update June 4, 2018,

on its evaluation of unleaded fuels for

general aviation, noting the completion of

the testing is now expected in late 2019.

According to agency officials, Phase

Two of the testing continues, reaching the

two-and-a-half year mark since the two

finalists in the Piston Aviation Fuels Ini-

tiative (PAFI) replacement unleaded fuels

program were chosen.

The flight test program of the fuels from

Shell and Swift Fuels is about one-third

complete, while the engine test program

is about halfway complete.

Differences in the two fuels compared

to 100LL are being evaluated for impacts

and mitigations, FAA officials said.

“While these issues are assessed, PAFI

flight testing and some engine testing

have been halted,” the update notes.

Both fuel producers, Shell and Swift,

are evaluating options to mitigate the im-

pacts that these differences will present in

fuel production, distribution, and opera-

tion in the GA fleet, FAA officials said in

the update.

“These evaluations will take time and

ultimately affect the schedule of the test

program,” officials said. “Based on cur-

rent projected activities and timelines, the

testing completion date for the PAFI pro-

gram will be December 2019.”

That’s a full year from the previous

predicted completion date of December

2018.

According to FAA officials, they are

interested in pursuing “all alternatives”

while the PAFI testing continues, so they

have invited companies that are develop-

ing unleaded avgas outside of the pro-

gram to “bring their data to the FAA for

evaluation and consideration for possible

detonation, operability, and performance

testing at the FAA’s William J. Hughes

Technical Center.”

“Fuel producers offering alternatives

determined to have potential viability as

an unleaded replacement for 100LL will

be invited to participate in a Cooperative

Research and Development Agreement

with the FAA, which will be conducted

on a non-interference basis with the PAFI

program,” FAA officials said.

“Corinne’s log revealed that two of the

tail numbers recorded in her log book

matched those in Kennedy’s flight log,

and in one instance, she flew the same

aircraft on the same day as JFK,” Mont-

gomery said.

With all the evidence in hand, Mont-

gomery contacted Presidential historian

Douglas Brinkley. After examining the

documents, Brinkley was convinced the

Kennedy flight logbook was authentic

and that it proved Kennedy had indeed

trained with Embry-Riddle.

Thanks to a small handful of people

at Embry-Riddle, and a 1944 flight log

from alumna and seaplane pilot Corinne

Smith, a decades-long legend has been

confirmed.
