§ 171.151 Scope. 

This subpart sets forth minimum re-

quirements for the approval and oper-
ation of non-Federal DME facilities 
that are to be involved in the approval 
of instrument flight rules and air traf-
fic control procedures related to those 
facilities. 

§ 171.153 Requests for IFR procedure. 

(a) Each person who requests an IFR 

procedure based on a DME 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 § 171.157 
and is installed in accordance with 
§ 171.159. 

(2) A proposed procedure for oper-

ating the facility. 

(3) A proposed maintenance organiza-

tion and maintenance manual that 
meets the requirement of § 171.161. 

(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 Federal Aviation Ad-

ministration inspects and evaluates 
the facility, it advises the owner of the 
results and of any required changes in 
the facility or the maintenance manual 
or maintenance organization. The 
owner must then correct the defi-
ciencies, if any, and operate the facil-
ity for an in-service evaluation by the 
Federal Aviation Administration.
