14 CFR Ch. I (1–1–24 Edition)

§ 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.

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.’’.

utility or acrobatic category that (A)
has a type certificate issued under this
chapter, (B) has a standard airworthi-
ness certificate issued under this chap-
ter, (C) has not undergone an acous-
tical change from its type design, (D)
