quirements of this subchapter as des-
ignated in § 21.17, or the applicable air-
craft noise, fuel venting, and exhaust 
emissions requirements of the State of 
Design, and any other requirements 
the FAA may prescribe to provide 
noise, fuel venting, and exhaust emis-
sion levels no greater than those pro-
vided by the applicable aircraft noise, 
fuel venting, and exhaust emission re-
quirements of this subchapter as des-
ignated in § 21.17; and 

(ii) The applicable airworthiness re-

quirements of this subchapter as des-
ignated in § 21.17, or the applicable air-
worthiness requirements of the State 
of Design and any other requirements 
the FAA may prescribe to provide a 
level of safety equivalent to that pro-
vided by the applicable airworthiness 
requirements of this subchapter as des-
ignated in § 21.17; 

(2) The applicant has provided tech-

nical data to show the product meets 
the requirements of paragraph (a)(1) of 
this section; and 

(3) The manuals, placards, listings, 

and instrument markings required by 
the applicable airworthiness (and 
noise, where applicable) requirements 
are presented in the English language. 

(b) A product type certificated under 

this section is considered to be type 
certificated under the noise standards 
of part 36 of this subchapter and the 
fuel venting and exhaust emission 
standards of part 34 of this subchapter. 
Compliance with parts 36 and 34 of this 
subchapter is certified under paragraph 
(a)(1)(i) of this section, and the applica-
ble airworthiness standards of this sub-

ty, with which compliance is certified 
under paragraph (a)(1)(ii) of this sec-

subchapter applicable to the product; 

(b) Information on dimensions, mate-

rials, and processes necessary to define 
the structural strength of the product;

(d) For primary category aircraft, if 

desired, a special inspection and pre-
ventive maintenance program designed 
to be accomplished by an appropriately 
rated and trained pilot-owner. 

(e) Any other data necessary to 

allow, by comparison, the determina-
tion of the airworthiness, noise charac-
teristics, fuel venting, and exhaust 
emissions (where applicable) of later 
products of the same type.
