What is an ELOS finding?

An Equivalent Level of Safety finding allows a project to deviate from a specific 14 CFR requirement when the alternative is shown to provide equivalent safety. Project-specific — not a precedent for other applicants.

14 CFR sections deviation applies to

  • § 21.21
  • § 23.1143
  • § 23.1147
