Executive Order 14304

Leading the World in Supersonic Flight

In simple terms

This executive order directs the FAA to repeal the 50-year ban on overland supersonic flight within 180 days and establish interim noise-based certification standards. It also mandates rulemaking for permanent supersonic aircraft noise standards within 18-24 months, coordinates federal R&D through OSTP, and directs international engagement to align global supersonic regulations.

Mechanisms

LicensingSubsidy / incentive

Role pressure

  • ProtectiveDomestic producer — US-based supersonic aircraft developers (Boom, Lockheed Martin Skunk Works) gain path to certify and operate overland, unlocking domestic market potential
  • MixedDownstream manufacturer — Engine and airframe suppliers benefit from new market but face compressed R&D timeline and uncertain final noise standards
  • ProtectiveProject developer — Commercial supersonic programs gain regulatory clarity and removal of fundamental market barrier, though certification uncertainty remains until final rule

Key directives

  • FAA Administrator shall repeal 14 CFR 91.817 prohibition on overland supersonic flight within 180 days
  • FAA Administrator shall establish interim noise-based certification standard and modify 14 CFR 91.818 within 180 days
  • FAA Administrator shall immediately repeal 14 CFR 91.819 and 91.821
  • FAA shall issue NPRM for supersonic noise certification under 14 CFR Part 36 within 18 months
  • FAA shall issue final rule within 24 months
  • OSTP Director shall coordinate supersonic R&D through National Science and Technology Council
  • Secretary of Transportation/FAA shall engage ICAO and foreign partners for regulatory alignment
  • FAA shall seek bilateral aviation safety agreements with foreign authorities

Who is ordered

What to expect

Immediate

  • FAA begins steps to repeal 14 CFR 91.819 and 91.821 immediately
  • OSTP begins coordinating interagency R&D council

Near term (90d)

  • FAA must repeal overland supersonic flight prohibition (14 CFR 91.817) and establish interim noise-based certification standard within 180 days

Long term

  • FAA must issue NPRM for permanent noise certification standard within 18 months
  • FAA must issue final rule within 24 months
  • OSTP to provide R&D results to inform future regulations
  • International engagement through ICAO and bilateral agreements ongoing

Risks & tensions

  • Community noise opposition may challenge 'community acceptability' criterion in rulemaking
  • Interim standard without full RDT&E data could create regulatory uncertainty for manufacturers
  • 18-24 month rulemaking timeline is aggressive for complex aerospace certification standards
  • Environmental groups may litigate over sonic boom environmental impacts not explicitly addressed
  • International alignment through ICAO may lag US domestic timeline, creating market fragmentation
  • 'Subject to availability of appropriations' clause may limit R&D coordination if budgets constrained
