14 CFR Part 22, effective July 24, 2026 under the MOSAIC final rule, created a light-sport powered-lift category that operates on manufacturer self-certification. The FAA issues no type certificate and conducts no bilateral MOC negotiation. The manufacturer signs a statement of compliance (FAA Form 8130-15) attesting conformance with FAA-accepted ASTM consensus standards.
The battery qualification standard in this lane is ASTM F3830-26, Electrical Energy Storage Systems, published June 2026, covering design, installation, and qualification of rechargeable lithium propulsion EESS. The FAA's powered-lift MOC table maps F3830-26 to five Subpart B requirements: §22.125, §22.130, §22.135, §22.145, and §22.155.
The accepting-authority structure is what matters for DVP work. F3830-26 does not satisfy a showing under AC 21.17-4. DO-311A and EASA MOC-3 do not satisfy a Part 22 SOC. These are different regulatory instruments accepted by different authorities, and citing across them is unresponsive to the lane you are actually qualifying in. F3830-26 is four pages and paywalled; at that length it almost certainly delegates test parameters to referenced standards, which means clause-level thresholds require chasing those references before any value enters a DVP.
Part 22 vs. AC 21.17-4 — Lane Comparison
| Part 22 (Light-Sport) | AC 21.17-4 (Type Cert) | |
|---|---|---|
| Basis | 14 CFR Part 22 (MOSAIC) | 14 CFR 21.17(b) |
| Certificate | Special airworthiness | Type certificate |
| Battery std | ASTM F3830-26 | DO-311A + EASA MOC-3 + applicant MOC |
| Accepting authority | Manufacturer (SOC signatory) | FAA |
| EASA equivalent | None established | SC-VTOL / VCA |
Key facts:
- Effective: July 24, 2026
- Integration std: ASTM F3840-26 references ~30 functional standards including F3830-26
- F3830-26 length: 4 pages — expect heavy reliance on referenced standards for test parameters
- Open gap: §22.180 (simplified flight controls) has no accepted consensus standard; compliance cannot be declared
- Weight limit: 1,320 lb gross weight reported for powered-lift (Tier 3 — verify against §22.100 controlled text)
