The FAA published its Modernization of Special Airworthiness Certification (MOSAIC) final rule on July 24, 2025. The first phase — the part that expanded sport pilot privileges — took effect October 22, 2025. The remaining certification and manufacturing provisions, including the new performance-based Part 22 framework replacing the old light-sport aircraft definition, completed the rollout on July 24, 2026.
For pilots flying out of Denton Enterprise Airport (KDTO), MOSAIC is the biggest practical change to the entry-level path into aviation in two decades. Below is a plain-language summary of what changed and what it means for a DFW pilot deciding between a sport pilot certificate and a private pilot certificate.
The headline: weight limits are gone, stall speed rules now
- The old 1,320 lb maximum takeoff weight limit for light sport aircraft is replaced by a clean stall speed limit of 59 knots CAS.
- Sport pilots may operate aircraft with up to four seats — but may still carry only one passenger.
- The previous 120 kt maximum speed cap for sport pilot operations was removed; new light sport designs are capped at 250 kcas under the new certification standards.
- Because the qualifying test is now stall speed and configuration, a number of familiar four-seat trainers may be eligible — but not all of them. Eligibility is aircraft-specific and must be verified model by model.
Why this matters if you're learning to fly in North Texas

A sport pilot certificate does not require an FAA medical certificate — a valid U.S. driver's license and self-certification of fitness to fly is the standard pathway. That removes the single most common source of delay and expense at the start of flight training. Combined with the wider range of eligible airframes under MOSAIC, sport pilot has moved from a niche certificate to a legitimate first step for a lot of Metroplex pilots.
| Question | Sport pilot | Private pilot |
|---|---|---|
| FAA medical required | No — driver's license standard | Yes — third class or BasicMed |
| Minimum FAA flight time | 20 hours | 40 hours |
| Passengers | One | Limited by aircraft seating |
| Night flight | Not permitted under sport privileges | Permitted with required training |
| Typical A4 path | Start in the Jabiru J170 | Start in the Jabiru, finish in the Cirrus SR20 |
How A4Flight Academy is handling it
- Our light sport trainer, N538J ("Jab", a Jabiru J170), remains the lowest-cost path to the left seat at KDTO and is available to members now.
- Every A4 aircraft record in the member portal carries the POH, weight and balance data, and inspection status, so eligibility questions get answered from documents rather than hearsay.
- Our Part 61 syllabus tracks FAA experience requirements per certificate, so a student who starts under sport pilot privileges and later moves to private doesn't lose credit for time already flown.
If you're weighing sport versus private, the honest answer usually depends on whether you want to fly at night, carry more than one passenger, and how your medical history looks. A discovery flight is the cheapest way to make that decision with real data instead of guesswork.
