Sec. 91.203  Civil aircraft: Certifications required.

    (a) Except as provided in Sec. 91.715, no person may operate a 
civil aircraft unless it has within it the following:
    (1) An appropriate and current airworthiness certificate. Each U.S. 
airworthiness certificate used to comply with this subparagraph (except 
a special flight permit, a copy of the applicable operations 
specifications issued under Sec. 21.197(c) of this chapter, appropriate 
sections of the air carrier manual required by parts 121 and 135 of this 
chapter containing that portion of the operations specifications issued 
under Sec. 21.197(c), or an authorization under Sec. 91.611) must have 
on it the registration number assigned to the aircraft under part 47 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 
certificate having on it an assigned special identification number, that 
has been affixed to an aircraft, may only be obtained upon application 
to an FAA Flight Standards district office.
    (2) An effective U.S. registration certificate issued to its owner 
or, for operation within the United States, the second duplicate copy 
(pink) of the Aircraft Registration Application as provided for in Sec. 
47.31(b), or a registration certificate issued under the laws of a 
foreign country.
    (b) No person may operate a civil aircraft unless the airworthiness 
certificate required by paragraph (a) of this section or a special 
flight authorization issued under Sec. 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 airplane (domestic or foreign) 
into or out of an airport in the United States unless it complies with 
the fuel venting and exhaust emissions requirements of part 34 of this 
chapter.
