14 CFR Ch. I (1–1–24 Edition) 

§ 36.1583 

(3) For rotorcraft, the noise level in-

formation must be one value for each 
takeoff, flyover, and approach as de-
fined and required by appendix H of 
this part, or one value for flyover as 
defined and required by appendix J of 
this part, at the maximum takeoff 
weight and configuration. 

(b) If supplemental operational noise 

level information is included in the ap-
proved portion of the Airplane Flight 
Manual, it must be segregated, identi-
fied as information in addition to the 
certificated noise levels, and clearly 
distinguished from the information re-
quired under § 36.1581(a). 

(c) The following statement must be 

furnished near the listed noise levels: 

No determination has been made by the Fed-
eral Aviation Administration that the noise 
levels of this aircraft are or should be ac-
ceptable or unacceptable for operation at, 
into, or out of, any airport. 

(d) For transport category large air-

planes and jet airplanes, for which the 
weight used in meeting the takeoff or 
landing noise requirements of this part 
is less than the maximum weight es-
tablished under the applicable air-
worthiness requirements, those lesser 
weights must be furnished, as oper-
ating limitations in the operating limi-
tations section of the Airplane Flight 
Manual. Further, the maximum takeoff 
weight must not exceed the takeoff 
weight that is most critical from a 
takeoff noise standpoint. 

(e) For propeller driven small air-

planes and for propeller-driven, com-
muter category airplanes for which the 
weight used in meeting the flyover 
noise requirements of this part is less 
than the maximum weight by an 
amount exceeding the amount of fuel 
needed to conduct the test, that lesser 
weight must be furnished, as an oper-
ating limitation, in the operating limi-
tations section of an approved Airplane 
Flight Manual, in approved manual 
material, or on an approved placard. 

(f) For primary, normal, transport, 

and restricted category helicopters, if 
the weight used in meeting the takeoff, 
flyover, or approach noise require-
ments of appendix H of this part, or the 
weight used in meeting the flyover 
noise requirement of appendix J of this 
part, is less than the certificated max-
imum takeoff weight established under 

either § 27.25(a) or § 29.25(a) of this chap-
ter, that lesser weight must be fur-
nished as an operating limitation in 
the operating limitations section of the 
Rotorcraft Flight Manual, in FAA-ap-
proved manual material, or on an FAA- 
approved placard. 

(g) Except as provided in paragraphs 

(d), (e), and (f) of this section, no oper-
ating limitations are furnished under 
this part.

§ 36.1583

Noncomplying agricultural 

and fire fighting airplanes. 

(a) This section applies to propeller- 

driven, small airplanes that— 

(1) Are designed for ‘‘agricultural air-

craft operations’’ (as defined in § 137.3 
of this chapter, effective on January 1, 
1966) or for dispensing fire fighting ma-
terials; and 

(2) Have not been shown to comply 

with the noise levels prescribed under 
appendix F of this part— 

(i) For which application is made for 

the original issue of a standard air-
worthiness certificate and that do not 
have any flight time before January 1, 
1980; or 

(ii) For which application is made for 

an acoustical change approval, for air-
planes which have a standard air-
worthiness certificate after the change 
in the type design, and that do not 
have any flight time in the changed 
configuration before January 1, 1980. 

(b) For airplanes covered by this sec-

tion an operating limitation reading as 
follows must be furnished in the man-
ner prescribed in § 36.1581: 

Noise abatement: This airplane has not 

been shown to comply with the noise limits 
in FAR Part 36 and must be operated in ac-
cordance with the noise operating limitation 
prescribed under FAR § 91.815.
