Subpart J—Special Airworthiness 




: Docket No. 6258, 29 FR 19202, Dec. 

31, 1964, unless otherwise noted. 

§ 121.211


(a) This subpart prescribes special 

airworthiness requirements applicable 
to certificate holders as stated in para-
graphs (b) through (e) of this section. 

(b) Except as provided in paragraph 

(d) of this section, each airplane type 
certificated under Aero Bulletin 7A or

meet the special airworthiness require-
ments in §§ 121.215 through 121.283.

ply with the requirements of §§ 121.285 
through 121.291. 

(d) If the Administrator determines 

that, for a particular model of airplane 
used in cargo service, literal compli-
ance with any requirement under para-
graph (b) of this section would be ex-

would not contribute materially to the 
objective sought, he may require com-
pliance only with those requirements 
that are necessary to accomplish the 
basic objectives of this part. 

(e) No person may operate under this 

part a nontransport category airplane 
type certificated after December 31, 
1964, unless the airplane meets the spe-
cial airworthiness requirements in
