Stage 2 Waivers

FAR 91.873 Stage 2 Waivers

FAR 91.873 explains how U.S. and foreign air carriers could apply for waivers from the Stage 2 airplane prohibition, including filing deadlines and limits.

In Plain English

FAR 91.873 lets a U.S. or foreign air carrier apply for a waiver from the Stage 2 airplane prohibition in § 91.853, but only under tight conditions tied to the late-1990s noise transition.

Key points:

  • The carrier had to have at least 85% of its fleet serving the contiguous U.S. compliant with Stage 3 noise levels by July 1, 1999.
  • Applications were due to the Secretary of Transportation by January 1, 1999 (U.S. carriers) or April 20, 2000 (foreign carriers), and had to include a plan with firm orders to replace or modify remaining airplanes.
  • A new entrant U.S. carrier had to begin service by January 1, 1999 to be eligible.
  • The Secretary may grant the waiver only if it is in the public interest, considering effects on competition and small community air service.
  • No waiver may allow Stage 2 operation in the contiguous U.S. after December 31, 2003.
  • Waiver requests are published for public comment (normally at least 14 days).

For pilots, this matters because it explains why nearly all transport-category jets operating in the U.S. today are Stage 3 (or quieter) compliant.

Regulation Text
14 CFR § 91.873
§ 91.873 Waivers from final compliance. (a) A U.S. air carrier or a foreign air carrier may apply for a waiver from the prohibition contained in § 91.853 of this part for its remaining Stage 2 airplanes, provided that, by July 1, 1999, at least 85 percent of the airplanes used by the carrier to provide service to or from an airport in the contiguous United States will comply with the Stage 3 noise levels. (b) An application for the waiver described in paragraph (a) of this section must be filed with the Secretary of Transportation no later than January 1, 1999, or, in the case of a foreign air carrier, no later than April 20, 2000. Such application must include a plan with firm orders for replacing or modifying all airplanes to comply with Stage 3 noise levels at the earliest practicable time.
