§ 91.203

Civil aircraft: Certifications 

required. 

(a) Except as provided in § 91.715, no 

person may operate a civil aircraft un-
less it has within it the following: 

(1) An appropriate and current air-

worthiness certificate. Each U.S. air-
worthiness certificate used to comply 
with this subparagraph (except a spe-
cial flight permit, a copy of the appli-
cable operations specifications issued 
under § 21.197(c) of this chapter, appro-
priate sections of the air carrier man-
ual required by parts 121 and 135 of this 
chapter containing that portion of the 
operations specifications issued under 
§ 21.197(c), or an authorization under 
§ 91.611) must have on it the registra-
tion number assigned to the aircraft 
under part 47 or 48 of this chapter. 
However, the airworthiness certificate 
need not have on it an assigned special 
identification number before 10 days 
after that number is first affixed to the 
aircraft. A revised airworthiness cer-
tificate having on it an assigned spe-
cial identification number, that has 
been affixed to an aircraft, may only be 
obtained upon application to the re-
sponsible Flight Standards office. 

(2) An effective U.S. registration cer-

tificate issued to its owner or, for oper-

ation within the United States, the 
second copy of the Aircraft registra-
tion Application as provided for in 
§ 47.31(c), a Certificate of Aircraft reg-
istration as provided in part 48, or a 
registration certification issued under 
the laws of a foreign country. 

(b) No person may operate a civil air-

craft unless the airworthiness certifi-
cate required by paragraph (a) of this 
section or a special flight authoriza-
tion issued under § 91.715 is displayed at 
the cabin or cockpit entrance so that it 
is legible to passengers or crew. 

(c) No person may operate an aircraft 

with a fuel tank installed within the 
passenger compartment or a baggage 
compartment unless the installation 
was accomplished pursuant to part 43 
of this chapter, and a copy of FAA 
Form 337 authorizing that installation 
is on board the aircraft. 

(d) No person may operate a civil air-

plane (domestic or foreign) into or out 
of an airport in the United States un-
less it complies with the fuel venting 
and exhaust emissions requirements of 
part 34 of this chapter.
