The FAA rewrote these rules in 2025 and most of what you will read elsewhere is out of date. The Modernization of Special Airworthiness Certification final rule appeared at 90 FR 35034 on 24 July 2025. Most of the rule took effect on 22 October 2025; a second set of amendments — including removal of the § 1.1 light-sport aircraft definition and the new light-sport airworthiness requirements in 14 CFR part 22 — took effect on 24 July 2026. Both sets are in force today, which means the old 1,320 lb weight limit no longer governs what a sport pilot may fly.
The definition of a light-sport aircraft that used to sit in 14 CFR 1.1 has gone with it. What a sport pilot may fly is set instead by 14 CFR 61.316, and the aircraft must have met every criterion since its original certification: a stall speed (VS1) of no more than 59 knots CAS for airplanes, measured at maximum certificated takeoff weight and the most critical center of gravity; a maximum seating capacity of four; a non-pressurised cabin; fixed landing gear; and a fixed, ground-adjustable or automated controllable-pitch propeller. There is no weight criterion at all. 14 CFR 61.316(b) then opens two more doors: an aircraft with retractable landing gear, or an airplane with a manual controllable-pitch propeller, once you have completed the training and received the endorsement required by 14 CFR 61.331. An automated controllable-pitch propeller needs no endorsement.
Night flying opened up as well. 14 CFR 61.329 now permits it after three hours of night flight training, a night cross-country landing at an airport at least twenty-five nautical miles away, ten night takeoffs and landings to a full stop, and an instructor endorsement. Read the rest of that section before you plan around it: night also requires an FAA medical certificate issued under part 67, or BasicMed under the conditions in 14 CFR 61.113(i). If skipping the medical was your reason for choosing sport, night stays closed.
One endorsement that is easy to miss sits in 14 CFR 61.327, and it is keyed to the aircraft rather than to the weather. It asks for a logbook endorsement based on VH, the maximum speed in level flight with maximum continuous power: one endorsement covers airplanes with a VH of 87 knots CAS or less, and a separate one covers aircraft above 87 knots, each with its own ground and flight training. Most of the standard-category airplanes MOSAIC brought within reach sit above that line, so for anyone moving up from a Cessna 162 this is routine rather than an edge case.
Nothing changed about the passenger limit, the ten-thousand-foot ceiling, the three-mile visibility requirement or the ban on flying for compensation or hire. And 14 CFR 61.23(c)(1)(ii) still accepts a valid United States driver license in place of a medical certificate for daytime sport flying, which is why this program exists at all.
The honest caveat we will give you at the consultation: whether a particular airplane now falls inside 14 CFR 61.316 depends on its published VS1 at maximum certificated takeoff weight, the FAA has published no list of eligible types, and 61.316(a) requires the aircraft to have met the criteria since its original certification, so nothing can be modified into compliance. The number is in the flight manual and on the type certificate data sheet. We will look it up with you rather than guess at it.
