The Federal Aviation Regulation that regulates ultralight flying is called Part 103. These are the legal rules we fly by; they are the most lenient rules in the world. Our privileges, however, carry responsibilities.
Part 103 defines an ultralight as:

  • 1-seat
  • 254 pounds max. empty weight (powered)
  • 155 pounds max empty weight (unpowered)
  • 5 gallons max. fuel capacity
  • 55 knots max. full power speed
  • 24 knots max power off stall speed

If the aircraft has more than 1-seat or exceeds any of the above criteria, is not an ultralight, and not eligible for operation under Part 103.
