The Frederick-Ames EOS-SFA was a single-seat sports aircraft designed in the United States in the 1970s with the intention of marketing it for homebuilding. It was a highly-streamlined low-wing cantilever monoplane with swept flying surfaces and retractable tricycle undercarriage. Its construction was of metal throughout. Originally named simply the Eos (for the Greek goddess of the dawn) it was shown at the 1973 EAA Fly-in at Oshkosh Wisconsin albeit in incomplete form.
