§ 91.803
stages of noise levels, the terms used to
describe airplanes with respect to those
levels, and the terms ‘‘subsonic air-
plane’’ and ‘‘supersonic airplane’’ have
the meanings specified under part 36 of
this chapter. For purposes of this sub-
part, for subsonic airplanes operated in
foreign air commerce in the United
States, the Administrator may accept
compliance with the noise require-
ments under annex 16 of the Inter-
national Civil Aviation Organization
when those requirements have been
shown to be substantially compatible
with, and achieve results equivalent to
those achievable under, part 36 for that
airplane. Determinations made under
these provisions are subject to the lim-
itations of § 36.5 of this chapter as if
those noise levels were part 36 noise
levels.
(c) Sections 91.851 through 91.877 of
this subpart prescribe operating noise
limits and related requirements that
apply to any civil subsonic jet (tur-
bojet) airplane (for which an airworthi-
ness certificate other than an experi-
mental certificate has been issued by
the Administrator) with a maximum
certificated takeoff weight of more
than 75,000 pounds operating to or from
an airport in the 48 contiguous United
States and the District of Columbia
under this part, parts 121, 125, 129, or
135 of this chapter on and after Sep-
tember 25, 1991.
(d) Section 91.877 prescribes reporting
requirements that apply to any civil
subsonic jet (turbojet) airplane with a
maximum weight of more than 75,000
pounds operated by an air carrier or
foreign air carrier between the contig-
uous United States and the State of
Hawaii, between the State of Hawaii
and any point outside of the 48 contig-
uous United States, or between the is-
lands of Hawaii in turnaround service,
under part 121 or 129 of this chapter on
or after November 5, 1990.
(e) Sections 91.881 through 91.883 of
this subpart prescribe operating noise
limits and related requirements that
apply to any civil subsonic jet airplane
with a maximum takeoff weight of
75,000 pounds or less and for which an
airworthiness certificate (other than
an experimental certificate) has been
issued, operating to or from an airport
in the contiguous United States under
this part, part 121, 125, 129, or 135 of
this chapter on and after December 31,
2015.
