14 CFR Part 135 Commercial Aviation Operations
by Nick Clark | Published April 25, 2026
14 CFR Part 135 establishes FAA's commercial-aviation certification and operational rules for commuter, on-demand, and emerging UAM operations. Governed actuation provides architectural substrate for emerging eVTOL Part 135 certification.
Part 135 Frame
14 CFR Part 135 establishes operating rules for commuter and on-demand commercial aviation. Emerging eVTOL operations and emerging UAM business models increasingly engage Part 135 certification.
Architecture Implications
Part 135 certification for emerging eVTOL operations requires structural support for phase-decomposed flight, operator authority composition, and incident reconstruction.
Architectural Mapping
Stage-gated commitment supports flight-phase decomposition. Composite admissibility supports multi-authority operations. Operator-intent substrate supports operator-of-record authority.
Part 135 Evolution
Emerging eVTOL Part 135 certification and emerging UAM regulatory framework push toward structurally-supported architecture.
