of instrument flight rules and air traf-
fic control procedures related to those
facilities.

amended by Amdt. 171–2, 31 FR 5408, Apr. 6,

§ 171.3 Requests for IFR procedure.
(a) Each person who requests an IFR
procedure based on a VOR facility that
he owns must submit the following in-
formation with that request:
(1) A description of the facility and
evidence that the equipment meets the
performance requirements of § 171.7 and
is installed in accordance with § 171.9.
(2) A proposed procedure for oper-
ating the facility.
(3) A proposed maintenance organiza-
tion and maintenance manual that
meets the requirements of § 171.11.
(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 paragraph.
(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
facility for an in-service evaluation by
the FAA.

§ 171.5 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 VOR:
(1) The facility’s performance, as de-
termined by air and ground inspection,
must meet the requirements of § 171.7.
(2) The installation of the equipment
must meet the requirements of § 171.9.
(3) The owner must agree to operate
and maintain the facility in accord-
ance with § 171.11.
(4) The owner must agree to furnish
periodic reports, as set forth in § 171.13,
and must agree to allow the FAA to in-
spect 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.

§ 171.7 Performance requirements.
(a) The VOR must perform in accord-
ance with the ‘‘International Stand-
ards and Recommended Practices,
Aeronautical Telecommunications,’’
Part I, paragraph 3.3 (Annex 10 to the
Convention on International Civil
Aviation), except that part of para-
graph 3.3.2.1 specifying a radio fre-
quency tolerance of 0.005 percent, and
that part of paragraph 3.3.7 requiring
removal of only the bearing informa-
tion. In place thereof, the frequency
tolerance of the radio frequency carrier
must not exceed plus or minus 0.002
percent, and all radiation must be re-
moved during the specified deviations
from established conditions and during
periods of monitor failure.
(b) Ground inspection consists of an
examination of the design features of
the equipment to determine that there
will not be conditions that will allow
unsafe operations because of compo-
nent failure or deterioration.
