§ 171.327 

§ 171.327 Operational records. 

The owner of the MLS facility or his 

maintenance representative must sub-
mit the following operational records 
at the indicated time to the appro-
priate FAA regional office where the 
facility is located. 

(a) 

Facility Equipment Performance & 

Adjustment Data (FAA Form 198). 

The 

FAA Form 198 shall be filled out by the 
owner or his maintenance representa-
tive with the equipment adjustments 
and meter readings as of the time of fa-
cility commissioning. One copy must 
be kept in the permanent records of the 
facility and two copies must be sent to 
the appropriate FAA regional office. 
The owner or his maintenance rep-
resentative must revise the FAA Form 
198 data after any major repair, mod-
ernization, or retuning to reflect an ac-
curate record of facility operation and 
adjustment. 

(b) 

Facility Maintenance Log (FAA 

Form 6030–1). 

FAA Form 6030–1 is per-

manent record of all the activities re-
quired to maintain the MLS facility. 
The entries must include all malfunc-
tions met in maintaining the facility 
including information on the kind of 

work and adjustments made, equip-
ment failures, causes (if determined) 
and corrective action taken. In addi-
tion, the entries must include comple-
tion of periodic maintenance required 
to maintain the facility. The owner or 
his maintenance representative must 
keep the original of each form at the 
facility and send a copy to the appro-
priate FAA regional office at the end of 
each month in which it is prepared. 
However, where an FAA approved re-
mote monitoring system is installed 
which precludes the need for periodic 
maintenance visits to the facility, 
monthly reports from the remote mon-
itoring system control point must be 
forwarded to the appropriate FAA re-
gional office, and a hard copy retained 
at the control point. 

(c) 

Technical Performance Record (FAA 

Form 6830 (formerly FAA Form 418)). 

This 

form contains a record of system pa-
rameters as specified in the manufac-
turer’s equipment manual. This data 
will be recorded on each scheduled visit 
to the facility. The owner or his main-
tenance representative shall keep the 
original of each record at the facility 
and send a copy of the form to the ap-
propriate FAA regional office.
