TITLE 14--AERONAUTICS AND SPACE
CHAPTER I--FEDERAL AVIATION ADMINISTRATION, DEPARTMENT OF TRANSPORTATION
PART 36--NOISE STANDARDS: AIRCRAFT TYPE AND AIRWORTHINESS CERTIFICATION--Table
of Contents
Subpart A--General
Sec. 36.1 Applicability and definitions.
(a) This part prescribes noise standards for the issue of the
following certificates:
(1) Type certificates, and changes to those certificates, and
standard airworthiness certificates, for subsonic transport category
large airplanes, and for subsonic jet airplanes regardless of category.
(2) Type certificates and changes to those certificates, standard
airworthiness certificates, and restricted category airworthiness
certificates, for propeller-driven, small airplanes, and for propeller-
driven, commuter category airplanes except those airplanes
[[Page 804]]
that are designed for ``agricultural aircraft operations'' (as defined
in Sec. 137.3 of this chapter, as effective on January 1, 1966) or for
dispersing fire fighting materials to which Sec. 36.1583 of this part
does not apply.
(3) A type certificate and changes to that certificate, and standard
airworthiness certificates, for Concorde airplanes.
(4) Type certificates, and changes to those certificates, for
helicopters except those helicopters that are designated exclusively for
``argicultural aircraft operations'' (as defined in Sec. 137.3 of this
chapter, as effective on January 1, 1966), for dispensing fire fighting
materials, or for carrying external loads (as defined in Sec. 133.1(b)
of this chapter, as effective on December 20, 1976).
(b) Each person who applies under Part 21 of this chapter for a type
of airworthiness certificate specified in this part must show compliance
with the applicable requirements of this part, in addition to the
applicable airworthiness requirements of this chapter.
(c) Each person who applies under Part 21 of this chapter for
approval of an acoustical change described in Sec. 21.93(b) of this
chapter must show that the aircraft complies with the applicable
provisions of Secs. 36.7, 36.9, or 36.11 of this part in addition to the
applicable airworthiness requirements of this chapter.
(d) Each person who applies for the original issue of a standard
airworthiness certificate for a transport category large airplane or for
a jet airplane under Sec. 21.183 must, regardless of date of
application, show compliance with the following provisions of this part
(including appendix B):
(1) The provisions of this part in effect on December 1, 1969, for
subsonic airplanes that have not had any flight time before--
(i) December 1, 1973, for airplanes with maximum weights greater
than 75,000 pounds, except for airplanes that are powered by Pratt &
Whitney Turbo Wasp JT3D series engines;
(ii) December 31, 1974, for airplanes with maximum weights greater
than 75,000 pounds and that are powered by Pratt & Whitney Turbo Wasp
JT3D series engines; and
(iii) December 31, 1974, for airplanes with maximum weights of
75,000 pounds and less.
(2) The provisions of this part in effect on October 13, 1977,
including the stage 2 noise limits, for Concorde airplanes that have not
had flight time before January 1, 1980.
(e) Each person who applies for the original issue of a standard
airworthiness certificate under Sec. 21.183, or for the original issue
of a restricted category airworthiness certificate under Sec. 21.185,
for propeller-driven, commuter category airplanes for a propeller driven
small airplane that has not had any flight time before January 1, 1980,
must show compliance with the applicable provisions of this part.
(f) For the purpose of showing compliance with this part for
transport category large airplanes and jet airplanes regardless of
category, the following terms have the following meanings:
(1) A ``Stage 1 noise level'' means a flyover, lateral or approach
noise level greater than the Stage 2 noise limits prescribed in section
B36.5(b) of appendix B of this part.
(2) A ``Stage 1 airplane'' means an airplane that has not been shown
under this part to comply with the flyover, lateral, and approach noise
levels required for Stage 2 or Stage 3 airplanes.
(3) A ``Stage 2 noise level'' means a noise level at or below the
Stage 2 noise limits prescribed in section B36.5(b) of appendix B of
this part but higher than the Stage 3 noise limits prescribed in section
B36.5(c) of appendix B of this part.
(4) A ``Stage 2 airplane'' means an airplane that has been shown
under this part to comply with Stage 2 noise levels prescribed in
section B36.5(b) of appendix B of this part (including use of the
applicable tradeoff provisions specified in section B36.6) and that does
not comply with the requirements for a Stage 3 airplane.
(5) A ``Stage 3 noise level'' means a noise level at or below the
Stage 3 noise limits prescribed in section B36.5(c) of appendix B of
this part.
(6) A ``Stage 3 airplane'' means an airplane that has been shown
under this part to comply with Stage 3 noise levels prescribed in
section B36.5(c) of
[[Page 805]]
appendix B of this part (including use of the applicable tradeoff
provisions specified in section B36.6).
(7) A ``subsonic airplane'' means an airplane for which the maximum
operating limit speed, Mmo, does not exceed a Mach number of
1.
(8) A ``supersonic airplane'' means an airplane for which the
maximum operating limit speed, Mmo, exceeds a Mach number of
1.
(g) For the purpose of showing compliance with this part for
transport category large airplanes and jet airplanes regardless of
category, each airplane may not be identified as complying with more
than one stage or configuration simultaneously.
(h) For the purpose of showing compliance with this part, for
helicopters in the primary, normal, transport, and restricted
categories, the following terms have the specified meanings:
(1) Stage 1 noise level means a takeoff, flyover, or approach noise
level greater than the Stage 2 noise limits prescribed in section
H36.305 of appendix H of this part, or a flyover noise level greater
than the Stage 2 noise limits prescribed in section J36.305 of appendix
J of this part.
(2) Stage 1 helicopter means a helicopter that has not been shown
under this part to comply with the takeoff, flyover, and approach noise
levels required for Stage 2 helicopters as prescribed in section H36.305
of appendix H of this part, or a helicopter that has not been shown
under this part to comply with the flyover noise level required for
Stage 2 helicopters as prescribed in section J36.305 of appendix J of
this part.
(3) Stage 2 noise level means a takeoff, flyover, or approach noise
level at or below the Stage 2 noise limits prescribed in section H36.305
of appendix H of this part, or a flyover noise level at or below the
Stage 2 limit prescribed in section J36.305 of appendix J of this part.
(4) Stage 2 helicopter means a helicopter that has been shown under
this part to comply with Stage 2 noise limits (including applicable
tradeoffs) prescribed in section H36.305 of appendix H of this part, or
