Applicability
Integration requirements for powered-lift and multicopters within the standard's light-sport scope; FAA acceptance is narrower.
Status
Published / FAA acceptance limited to powered-lift
Plain-English Explainer
F3840-26 organizes requirements for a light-sport powered-lift or multicopter within F3851-26 and its referenced standards.
The FAA accepts F3840-26 as a means of compliance for powered-lift light-sport category aircraft, subject to its published limitations. The word multicopter in the ASTM title does not extend that acceptance to every multicopter.
The FAA table's simplified-flight-control limitation remains material. This entry is based on public official scope and acceptance material; the full paid standard has not been reproduced or reviewed clause by clause.
