CHAPTER I--FEDERAL AVIATION ADMINISTRATION, DEPARTMENT OF TRANSPORTATION 
                               (CONTINUED)
 
PART 121_OPERATING REQUIREMENTS: DOMESTIC, FLAG, AND SUPPLEMENTAL OPERATIONS--
 
                       Subpart T_Flight Operations
 
Sec. 121.590  Use of certificated land airports in the United States.

carrier and no

pilot being used by an air carrier may operate, in the conduct of a 
domestic type operation, flag type operation, or supplemental type 
operation, an airplane at a land airport in any State of the United 
States, the District of Columbia, or any territory or possession of the 
United States unless that airport is certificated under part 139 of this 
chapter. Further, after June 9, 2005 for Class I airports and after 
December 9, 2005 for Class II, III, and IV airports, when an air carrier 
and a pilot being used by the air carrier are required to operate at an 
airport certificated under part 139 of this chapter, the air carrier and 
the pilot may only operate at that airport if the airport is classified 
under part 139 to serve the type airplane to be operated and the type of 
operation to be conducted.
    (b)(1) An air carrier and a pilot being used by the air carrier in 
the conduct of a domestic type operation, flag type operation, or 
supplemental type operation may designate and use as a required 
alternate airport for departure or destination an airport that is not 
certificated under part 139 of this chapter.
    (2) Until December 9, 2005, an air carrier and a pilot being used by 
the air carrier in the conduct of domestic type operations and flag type 
operations, may operate an airplane designed for more than 9 but less 
than 31 passenger seats, at a land airport, in any State of the United 
States, the District of Columbia, or any territory or possession of the 
United States, that does not hold an airport operating certificate 
issued under part 139 of this chapter, and that serves small air carrier 
aircraft (as defined under ``Air carrier aircraft'' and ``Class III 
airport'' in Sec. 139.5 of this Chapter).
    (c) An air carrier and a pilot used by the air carrier in conducting 
a domestic type operation, flag type operation, or supplemental type 
operation may operate an airplane at an airport operated by the U.S. 
Government that is not certificated under part 139 of this chapter, only 
if that airport meets the equivalent--
    (1) Safety standards for airports certificated under part 139 of 
this chapter; and
    (2) Airport classification requirements under part 139 to serve the 
type airplane to be operated and the type of operation to be conducted.
    (d) An air carrier, a commercial operator, and a pilot being used by 
the air carrier or the commercial operator--when conducting a passenger-
carrying airplane operation under this part that is not a domestic type 
operation, a flag type operation, or a supplemental type operation--may 
operate at a land airport not certificated under part 139 of this 
chapter only when the following conditions are met:
    (1) The airport is adequate for the proposed operation, considering 
such items as size, surface, obstructions, and lighting.
    (2) For an airplane carrying passengers at night, the pilot may not 
take off from, or land at, an airport unless--
    (i) The pilot has determined the wind direction from an illuminated 
wind direction indicator or local ground communications or, in the case 
of takeoff, that pilot's personal observations; and
    (ii) The limits of the area to be used for landing or takeoff are 
clearly shown by boundary or runway marker lights. If the area to be 
used for takeoff or landing is marked by flare pots or lanterns, their 
use must be authorized by the Administrator.
    (e) A commercial operator and a pilot used by the commercial 
operator in conducting a domestic type operation, flag type operation, 
or supplemental type operation may operate an airplane at an airport 
operated by the U.S. Government that is not certificated under part 139 
of this chapter only if that airport meets the equivalent--
    (1) Safety standards for airports certificated under part 139 of 
this chapter; and
    (2) Airport classification requirements under part 139 of this 
chapter to serve the type airplane to be operated and the type of 
operation to be conducted.
    (f) For the purpose of this section, the terms--
    Domestic type operation means any domestic operation conducted 
with--
    (1) An airplane designed for at least 31 passenger seats (as 
determined by the aircraft type certificate issued by a

[[Page 870]]

competent civil aviation authority) at any land airport in any State of 
the United States, the District of Columbia, or any territory or 
possession of the United States; or
    (2) An airplane designed for more than 9 passenger seats but less 
than 31 passenger seats (as determined by the aircraft type certificate 
issued by a competent civil aviation authority) at any land airport in 
any State of the United States (except Alaska), the District of 
Columbia, or any territory or possession of the United States.
    Flag type operation means any flag operation conducted with--
    (1) An airplane designed for at least 31 passenger seats (as 
determined by the aircraft type certificate issued by a competent civil 
aviation authority) at any land airport in any State of the United 
States, the District of Columbia, or any territory or possession of the 
United States; or
    (2) An airplane designed for more than 9 passenger seats but less 
than 31 passenger seats (as determined by the aircraft type certificate 
issued by a competent civil aviation authority) at any land airport in 
any State of the United States (except Alaska), the District of 
Columbia, or any territory or possession of the United States.
    Supplemental type operation means any supplemental operation (except 
an all-cargo operation) conducted with an airplane designed for at least 
31 passenger seats (as determined by the aircraft type certificate 
issued by a competent civil aviation authority) at any land airport in 
any State of the United States, the District of Columbia, or any 
territory or possession of the United States.
    United States means the States of the United States, the District of 
Columbia, and the territories and possessions of the United States.
    Note: Special Statutory Requirement to Operate to or From a Part 139 
Airport. Each air carrier that provides--in an aircraft (e.g., airplane, 
rotorcraft, etc.) designed for more than 9 passenger seats--regularly 
scheduled charter air transportation for which the public is provided in 
advance a schedule containing the departure location, departure time, 
and arrival location of the flight must operate to and from an airport 
certificated under part 139 of this chapter in accordance with 49 U.S.C. 
41104(b). That statutory provision contains stand-alone requirements for 
such air carriers and special exceptions for operations in Alaska and 
outside the United States. Nothing in Sec. 121.590 exempts the air 
carriers described in this note from the requirements of 49 U.S.C. 
41104(b). Certain operations by air carriers that conduct public charter 
operations under 14 CFR part 380 are covered by the statutory 
requirements to operate to and from part 139 airports. See 49 U.S.C. 
41104(b).
