§ 36.103 

§ 36.103

Noise limits. 

(a) For subsonic transport category 

large airplanes and subsonic jet air-
planes compliance with this section 
must be shown with noise levels meas-
ured and evaluated as prescribed in ap-
pendix A of this part, and dem-
onstrated at the measuring points, and 
in accordance with the test procedures 
under section B36.8 (or an approved 
equivalent procedure), stated under ap-
pendix B of this part. 

(b) Type certification applications 

between November 5, 1975 and Decem-
ber 31, 2005. If application is made on or 
after November 5, 1975, and before Jan-
uary 1, 2006, it must be shown that the 
noise levels of the airplane are no 
greater than the Stage 3 noise limit 
prescribed in section B36.5(c) of appen-
dix B of this part. 

(c) Type certification applications 

between January 1, 2006, and the date 
specified in paragraph (d) or (e) of this 
section, as applicable for airplane 
weight. If application is made on or 
after January 1, 2006, and before the 
date specified in paragraph (d) or (e) of 
this section (as applicable for airplane 
weight), it must be shown that the 
noise levels of the airplane are no 
greater than the Stage 4 noise limit 
prescribed in section B36.5(d) of appen-
dix B of this part. If an applicant chose 
to voluntarily certificate an airplane 
to Stage 4 prior to January 2006, then 
the requirements of § 36.7(f) apply to 
that airplane. 

(d) For airplanes with a maximum 

certificated takeoff weight of 121,254 
pounds (55,000 kg) or more, type certifi-
cation applications on or after Decem-
ber 31, 2017. If application is made on or 
after December 31, 2017, it must be 
shown that the noise levels of the air-
plane are no greater than the Stage 5 
noise limit prescribed in section 
B36.5(e) of appendix B of this part. 
Prior to December 31, 2017, an appli-
cant may seek voluntary certification 
to Stage 5. If Stage 5 certification is 
chosen, the requirements of § 36.7(g) 
will apply. 

(e) For airplanes with a maximum 

certificated take-off weight of less 
than 121,254 pounds (55,000 kg), type 
certification applications on or after 
December 31, 2020. If application is 
made on or after December 31, 2020, it 

must be shown that the noise levels of 
the airplane are no greater than the 
Stage 5 noise limit prescribed in sec-
tion B36.5(e) of appendix B of this part. 
Prior to December 31, 2020, an appli-
cant may seek voluntary certification 
to Stage 5. If Stage 5 certification is 
chosen, the requirements of § 36.7(g) 
will apply.

§ 36.105

Flight Manual Statement of 

Chapter 4 equivalency. 

For each airplane that meets the re-

quirements for Stage 4 certification, 
the Airplane Flight Manual or oper-
ations manual must include the fol-
lowing statement: ‘‘The following noise 
levels comply with part 36, Appendix B, 
Stage 4 maximum noise level require-
ments and were obtained by analysis of 
approved data from noise tests con-
ducted under the provisions of part 36, 
Amendment 36 (insert part 36 amend-
ment to which the airplane was certifi-
cated). The noise measurement and 
evaluation procedures used to obtain 
these noise levels are considered by the 
FAA to be equivalent to the Chapter 4 
noise level required by the Inter-
national Civil Aviation Organization 
(ICAO) in Annex 16, Volume I, Appen-
dix 2, Amendment 7, effective March 21, 
2002.’’.
