FAA Announces Final Mosaic Rule at EAA AirVenture Oshkosh Event - Aviation International News
FAA has finalized the Mosaic rule, modernizing pilot training and certification requirements, affecting Part 61, 91, 135, and 141 operations. The rule expands the use of flight simulators, updates medical certification, and introduces a new 'BasicMed' option for certain operations.
Aforeworn detected this change in the Aviation Maintenance & Airworthiness (FAA) space on July 28, 2026 and published this briefing so affected operators are forewarned rather than caught off guard. It is rated High urgency. Part 135/121 operators, flight schools, corporate flight departments, Part 145 repair stations (indirectly via training requirements) should confirm how it applies to their specific situation before acting. There is a time constraint attached: Effective 60 days after publication in Federal Register; compliance deadlines vary by provision (some immediate, others phased over 1-2 years).. Acting after that point can mean penalties, a lapsed licence, or lost eligibility — exactly the kind of surprise Aforeworn exists to prevent. Aforeworn monitors Aviation Maintenance & Airworthiness (FAA) continuously and turns every detected change into a plain-English briefing like this one, so you always know first. Forewarned is forearmed.
