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.’’ [Incorporated by reference, see
§ 36.6].
