MOSAIC is here.
Bristell is ready.

MOSAIC (Modernization of Special Airworthiness Certification) is the FAA’s final rule, published in the Federal Register on July 24, 2025. It retires the 2004 Light Sport Aircraft weight limit and replaces it with a performance-based standard built around stall speed — opening the door to a far more capable class of light aircraft.

In two phases. Expanded Sport Pilot privileges have been in effect since October 22, 2025. The framework for certificating new light sport aircraft takes effect July 24, 2026.

Think of MOSAIC as the Light Sport category you already know — with the limits lifted. The old 1,320 lbs (600 kg) weight cap is gone, replaced by how slowly an aircraft flies: a clean stall speed of 61 knots (70 mph) or below. That one change unlocks higher gross weights and useful load, top speeds up to 250 KCAS (288 mph), retractable landing gear, constant-speed propellers, and advanced avionics — capability the old LSA rules never allowed.

Yes — that is exactly what MOSAIC opened up. To fly an aircraft under Sport Pilot privileges it must have a clean stall speed of 59 KCAS (68 mph) or below, carry no more than one passenger, and be flown day VFR. Bristell configures B23M variants to meet the Sport Pilot envelope — tell us your mission and our US team will confirm which one fits your certificate. A higher certificate unlocks more of each airframe’s capability.

No new certificate. MOSAIC did not change your Sport Pilot certificate — it expanded what that certificate lets you fly. You keep flying day VFR with one passenger. A qualifying aircraft’s added capabilities, such as a constant-speed propeller or retractable gear, simply need a short instructor endorsement, and stepping into a roomier, faster airframe is worth a few hours of transition training.

Yes — you can order now. The Bristell B23-912 is FAA Part 23 certified and available today, and the B23M is engineered MOSAIC-ready for the expanded envelope. The FAA’s framework to certificate new light sport aircraft opens July 24, 2026; order now to be first in line, and our US team will match your order to the right certification path. Book a demo flight and we’ll walk you through options, availability, and delivery timing.

Night: yes — with additional training, an instructor endorsement, and a medical or BasicMed, Sport Pilots can fly at night under MOSAIC. IFR is different: a MOSAIC aircraft can be equipped with IFR-capable avionics, but Sport Pilots still fly VFR only. A higher certificate is needed to fly IFR.

A MOSAIC light sport airplane can be built with up to four seats. A Sport Pilot, however, may still carry only one passenger (two occupants total). Pilots holding higher certificates can use the additional seats.

It is built for it. One airframe can carry a student from their first lesson under Sport Pilot rules through to higher certificates — same panel, same handling, fewer checkouts. Up to 661 lbs (300 kg) of useful load means a full-size instructor, a full-size student, and real fuel without trading one for the other, and the Garmin G3X Touch glass panel is what students want to train on. With Rotax efficiency and a new airframe, the cost per hour works hard against an aging fleet. Ask our US team for a flight-school and fleet quote.

The B23 is our type-certified airframe — EASA CS-23 in Europe and FAA Part 23 in the US (certified as the B23-912, with further variants in progress) — flown in more than 30 countries. The B23M is the MOSAIC configuration of that same airframe, adapted for the US market — the proven structure and build quality, set up for the expanded MOSAIC envelope, with a maximum takeoff weight 1,653 lbs (750 kg) and up to 661 lbs (300 kg) of useful load.
