§ 171.23
§ 171.13 Reports.
The owner of each facility to which
this subpart applies shall make the fol-
lowing reports on forms furnished by
the FAA, at the times indicated, to the
FAA Regional office for the area in
which the facility is located:
(a)
Record of meter readings and adjust-
ments
(
Form FAA–198
). To be filled out
by the owner with the equipment ad-
justments and meter readings as of the
time of commissioning, with one copy
to be kept in the permanent records of
the facility and two copies to the ap-
propriate Regional office of the FAA.
The owner shall revise the form after
any major repair, modernization, or re-
turning, to reflect an accurate record
of facility operation and adjustment.
(b)
Facility maintenance log
(
FAA Form
6003–1
). This form is a permanent
record of all equipment malfunctioning
met in maintaining the facility, in-
cluding information on the kind of
work and adjustments made, equip-
ment failures, causes (if determined),
and corrective action taken. The owner
shall keep the original of each report
at the facility and send a copy to the
appropriate Regional office of the FAA
at the end of the month in which it is
prepared.
(c)
Radio equipment operation record
(
Form FAA–418
). To contain a complete
record of meter readings, recorded on
each scheduled visit to the facility.
The owner shall keep the original of
each month’s record at the facility and
send a copy of it to the appropriate Re-
gional office of the FAA.
(d) [Reserved]
(e)
VOR ground check error data
(
Forms FAA–2396 and 2397
). To contain
results of the monthly course accuracy
ground check in accordance with FAA

Instructions for VHF Omniranges’’.
The owner shall keep the originals in
the facility and send a copy of each
form to the appropriate Regional office
of the FAA on a monthly basis.

Subpart B—Nondirectional Radio
Beacon Facilities
§ 171.21 Scope.
(a) This subpart sets forth minimum
requirements for the approval and op-
eration of non-Federal, nondirectional
radio beacon facilities that are to be
involved in the approval of instrument
flight rules and air traffic control pro-
cedures related to those facilities.
(b) A nondirectional radio beacon
(‘‘H’’ facilities domestically—NDB fa-
cilities internationally) radiates a con-
tinuous carrier of approximately equal
intensity at all azimuths. The carrier
is modulated at 1020 cycles per second
for station identification purposes.

amended by Amdt. 171–2, 31 FR 5408, Apr. 6,
1966; Amdt. 171–7, 35 FR 12711, Aug. 11, 1970]
§ 171.23 Requests for IFR procedure.
(a) Each person who requests an IFR
procedure based on a nondirectional
radio beacon facility that he owns
must submit the following information
with that request:
(1) A description of the facility and
evidence that the equipment meets the
performance requirements of § 171.27
and is installed in accordance with
§ 171.29.
(2) A proposed procedure for oper-
ating the facility.
(3) A proposed maintenance arrange-
ment and a maintenance manual that
meets the requirements of § 171.31.
(4) A statement of intention to meet
the requirements of this subpart.
(5) A showing that the facility has an
acceptable level of operational reli-
ability and an acceptable standard of
performance. Previous equivalent oper-
ational experience with a facility with
identical design and operational char-
acteristics will be considered in show-
ing compliance with this subparagraph.
(b) After the FAA inspects and evalu-
ates the facility, it advises the owner
of the results and of any required
changes in the facility or the mainte-
nance manual or maintenance organi-
zation. The owner must then correct
the deficiencies, if any, and operate the
820
14 CFR Ch. I (1–1–24 Edition)
§ 171.25
facility for an in-service evaluation by
the FAA.
[Doc. No. 5034, 29 FR 11337, Aug. 6, 1964, as
amended by Amdt. 171–7, 35 FR 12711, Aug. 11,
1970]
§ 171.25 Minimum requirements for ap-
proval.
(a) The following are the minimum
requirements that must be met before
the FAA will approve an IFR procedure
for a non-Federal, nondirectional radio
beacon facility under this subpart:
(1) The facility’s performances, as de-
termined by air and ground inspection,
must meet the requirements of § 171.27.
(2) The installation of the equipment
must meet the requirements of § 171.29.
(3) The owner must agree to operate
and maintain the facility in accord-
ance with § 171.31.
(4) The owner must agree to furnish
periodic reports, as set forth in § 171.33,
and agree to allow the FAA to inspect
the facility and its operation whenever
necessary.
(5) The owner must assure the FAA
that he will not withdraw the facility
from service without the permission of
the FAA.
(6) The owner must bear all costs of
meeting the requirements of this sec-
tion and of any flight or ground inspec-
tions made before the facility is com-
missioned, except that the Federal
Aviation Administration may bear cer-
tain of these costs subject to budgetary
limitations and policy established by
the Administrator.
(b) If the applicant for approval
meets the requirements of paragraph
(a) of this section, the FAA commis-
sions the facility as a prerequisite to
its approval for use in an IFR proce-
dure. The approval is withdrawn at any
time the facility does not continue to
meet those requirements. In addition,
the facility may be de-commissioned
whenever the frequency channel is
needed for higher priority common sys-
tem service.

amended by Amdt. 171–6, 35 FR 10288, June

§ 171.27 Performance requirements.
(a) The facility must meet the per-
formance requirements set forth in the
‘‘International Standards and Rec-
ommended Practices, Aeronautical
Telecommunications, Part I, paragraph
3.4’’ (Annex 10 to the Convention on
International Civil Aviation), except
that identification by on-off keying of
a second carrier frequency, separated
from the main carrier by 1020 Hz plus
or minus 50 Hz, is also acceptable.
(b) The facility must perform in ac-
cordance with recognized and accepted
good electronic engineering practices
for the desired service.
(c) Ground inspection consists of an
examination of the design features of
the equipment to determine (based on
recognized and accepted good engineer-
ing practices) that there will not be
conditions that will allow unsafe oper-
ations because of component failure or
deterioration.
(d) Flight tests to determine the fa-
cility’s adequacy for operational re-
quirements and compliance with appli-
cable ‘‘Standards and Recommended
Practices’’ are conducted in accord-
ance with the ‘‘U.S. Standard Flight
Inspection Manual’’, particularly sec-
tion 207. The original test is made by
the FAA and later tests shall be made
under arrangements, satisfactory to
the FAA, that are made by the owner.

1970]
§ 171.29 Installation requirements.
(a) The facility must be installed ac-
cording to accepted good engineering
practices, applicable electric and safe-
ty codes, and FCC licensing require-
ments.
(b) The facility must have a reliable
source of suitable primary power.
(c) Dual transmitting equipment may
be required to support some IFR proce-
dures.
(d) A facility intended for use as an
instrument approach aid for an airport
must have or be supplemented by (de-
pending on the circumstances) the fol-
lowing ground-air or landline commu-
nications services:
(1) At facilities outside of and not im-
mediately adjacent to controlled air-
space, there must be ground-air com-
munications from the airport served by
the facility. Voice on the aid con-
trolled from the airport is acceptable.
