FAA Proposes New Aircraft Certification Modernization Rules

The Federal Aviation Administration (FAA) has initiated a significant regulatory overhaul aimed at streamlining the approval process for new commercial aircraft. Through the Transport Airplane and Propulsion Certification Modernization (Docket No. FAA-2026-0430) Notice of Proposed Rulemaking (NPRM), the agency seeks to update Part 25 airworthiness standards. This initiative focuses on reducing the frequency of exemptions, special conditions, and equivalent safety findings that have historically complicated the certification landscape for transport category airplanes.

Driving Regulatory Harmonization

A primary goal of this proposal is to achieve greater EASA regulatory harmonization. By aligning its specifications with the European Union Aviation Safety Agency (EASA), the FAA aims to reduce redundant testing requirements for manufacturers. This shift toward a unified regulatory framework is expected to lower compliance costs and simplify the global certification process. The FAA has opened a 60-day public comment period for these proposed changes, which is scheduled to conclude on August 25, 2026.

Impact on Boeing 737 MAX Certification

While the agency works on long-term modernization, current programs remain under intense scrutiny. FAA Deputy Administrator Chris Rocheleau confirmed that the agency is in the final stages of certifying the Boeing 737 MAX 7 and MAX 10 variants. EASA Executive Director Florian Guillermet echoed this sentiment, stating that validating the MAX 10 remains a top priority. Guillermet noted that the agencies are nearing the closure of final actions, which would allow the industry to move forward from the prolonged oversight era that followed the 2019 grounding of the fleet.

Historical Context and Safety Oversight

This move toward modernization follows the precedent set by the 2017 FAA Part 23 rewrite, which successfully transitioned general aviation standards to a performance-based model. The current proposal represents a structural evolution of the reforms mandated by the 2020 Aircraft Certification, Safety, and Accountability Act. However, some safety advocates maintain that the FAA must balance efficiency with rigorous independent oversight. These groups argue that speeding up certification should not come at the expense of thorough design validation, urging the agency to maintain strict scrutiny despite the push for faster delivery cycles.

Stakeholder Implications

For commercial aircraft manufacturers, including Boeing, Airbus, and Embraer, the proposed harmonization offers a high-impact reduction in administrative complexity. Airlines and operators stand to benefit from more predictable aircraft delivery timelines, as streamlined certification processes minimize the risk of unexpected delays for new variants. Regulators, meanwhile, expect to see a more efficient allocation of resources by reducing the duplication of evaluation efforts across different international jurisdictions.

What Comes Next: Certification Milestones

The regulatory process remains active as the industry monitors key upcoming dates. The public comment period for the modernization NPRM is confirmed to close on August 25, 2026. Simultaneously, the FAA expects to finalize the type certification for the Boeing 737 MAX 7 during the summer of 2026, with the Boeing 737 MAX 10 certification anticipated for late 2026. These milestones represent the final steps in the current certification cycle before the proposed modernization framework potentially takes full effect for future programs.

Why This Matters for Global Aviation

This regulatory shift signals a strategic move toward a more integrated global aerospace market. By reducing the regulatory friction between the US and Europe, the FAA is positioning the industry to handle the next wave of fleet renewals with greater agility. For the broader aviation sector, the success of this harmonization effort will determine whether regulators can maintain high safety standards while providing the predictability required by manufacturers and airlines to manage long-term capital investments.
