14 CFR Ch. I (1–1–24 Edition) 

§ 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.
