Codes For Nondesignated Alaska Airports
Department of Transportation, Research and Special Programs Administration, Office
of Airline Statistics Number 186
Issue Date: 2/14/95
Effective Date: 4/1/95
Part: 298
This Accounting and Reporting Directives directs small certificated and commuter air
carriers to use the airport code ZZZ for landing areas in Alaska which do not have an
official IATA or DOT airport code.
The Office of Airline Statistics and its Alaskan Aviation Field Office have been
expending an increasing amount of time researching and assigning airport codes for
nondesignated landing areas. Frequently, on a scheduled flight, an Alaskan bush
carrier will divert from its scheduled routing to transport passengers to a nonscheduled
point, which may be a nondesignated landing area. For example, it may transport
sportsmen to a hunting lodge, or lumberjacks to their work sites. The directions
[Title 14 Code of Federal Regulations (14 C.F.R.) §298.61(f)(5)] to Form 298-C,
Schedule T-1 Report Qf Revenue Traffic by on-Ling origin and Destination instruct
carriers to assign their own airport code if there is no code found in the Official
Airline Guide (OAG). Often times the carrier has mistakenly assigned a code which
is already an official code for another airport. In the past, a single carrier
has made up as many as 20 codes in a single quarter for nondesignated airports.
The use of the ZZZ code will save scarce DOT resources with no additional burden to
air carriers.
We request carriers to combine passenger counts from the same designated airport to
different ZZZ points. For example, in a reporting quarter, a carrier transports
(on its scheduled service 11 passengers from Anchorage to a nondesignated hunting
lodge and 20 others from Anchorage to a nondesignated lumber camp. The carrier
would report 31 passengers carried from ANC-ZZZ on its Schedule T-1.
Please note, the data items reported on Schedule A-1 Report of Flight and Traffic
Statistics in Scheduled Passenger Operations will not be affected by the use of the
ZZZ code. Carriers will continue to compute mileage statistics based on the location
of the nondesignated landing area(s).
Commuter and small Certificated air carriers operating within Alaska will receive a
listing of the official airport codes in the State of Alaska.
If you have any questions concerning an airport code, please call Ms.Victoria Bradford
on (202) 366-4393 or Ms. Dianna Strain an (907) 271-5147.
This directive is issued under authority delegated by 14 C.F.R. 385.27(e).
