• Improve safety by enabling more flexibility for safety-enhancing designs; establishing new design, production, and airworthiness standards; and positioning LSA as a more attractive alternative to aircraft that are lower on the AVS safety continuum.
• Improve ruggedness, cabin space, seating capacity, fuel capacity, and performance.
• Allow new types of LSA such as gyroplanes, rotorcraft, and powered-lift.
• Allow new types of propulsion, including turbine engines and electric motors.

• Expand what aircraft sport pilots can operate. See new 14 CFR § 61.316. No longer limited to 14 CFR Part 1.1 "light-sport aircraft" definition.
• Enable operations of aircraft with retractable landing gear, airplanes with manual controllable pitch propellers, high performance airplanes, and complex airplanes with training and instructor endorsements.
• Allow new night privileges with training and endorsements. Requires FAA medical or BasicMed medical qualification for night operations.
• Add new helicopter class privilege. Limited to LSA helicopters with the simplified flight controls (SFC) designation.

Expand the privileges of LSR to: 

• Perform maintenance on all aircraft within the expanded light-sport category, including new aircraft types and designs that will qualify as LSA under MOSAIC. 
• Conduct the condition inspection on experimental amateur-built aircraft.

• Reduce owner burden by allowing minor repairs and minor alterations to be performed in accordance with Part 43 maintenance standards without requiring manufacturer approval.
• Allow voluntary compliance by aircraft owners and operators with manufacturer-issued safety directives and service information.

• Enable certain aerial work operations with LSA.
