Order 6000.15G, Change 1, General Maintenance Handbook for National Airspace System (NAS) Facilities.

Sites must now use electronic TPR (eTPR) Application in the Remote Monitoring and Logging System (RMLS) to collect and analyze technical performance information unless exempted.

Appendix C, Facility Maintenance Documentation Requirements lists all Facility Service Equipment Profile (FSEP) entities and indicates whether or not they require a TPR.

The following criteria are used to determine if a TPR is required: 1. We have published the entity in the FSEP. 2. The entity is a tangible element of the NAS producing or distributing communication, navigation, surveillance, automation, aeronautical information, power, or providing environmental support. 3. The entity has a maintenance handbook requirement to document the recurring measurement of parameters with variable readings. HQ personnel must review maintenance handbooks to determine TPR requirements.

Maintenance Handbook OPR must: 1. Establish a system specific eTPR Template for each specific class of system or subsystem defined by the Facility Identification Code (FIC) and Class codes in the FSEP if listed as requiring a TPR in Appendix D. 2. Publish update, and maintain eTPR Templates in RMLS for each system or subsystem class that requires a TPR. 3. Determine which parameters require tracking and analysis on an eTPR Template.

The Handbook OPR may use the following guidelines in making the determination for parameters requiring tracking and analysis on an eTPR Template: 1. Key Performance Parameters (KPP) that provide valuable data for trend analysis. 2. Performance parameters that provide valuable data for RCM analysis. 3. Certification parameters included in periodic measurements. 4. Parameters designated in the maintenance procedures as “measure and record” or similar verbiage.

Include parameters with non-numerical readings such as pass/fail or go/no go. Systems with only non-numerical parameters typically do require a TPR.

Maintenance personnel must record measured values of each parameter included in the eTPR Workbook on a periodic or on an as-needed basis as specified in the appropriate maintenance handbook.

The eTPR Application will store the eTPR entries in SAL.

Unless specifically required in the maintenance handbook, maintenance personnel must use standard rounded-off measurements to the least significant digit of the prescribed standard value or tolerance.

Maintenance personnel must coordinate all maintenance activities that may adversely affect the service provided by a commissioned facility with air traffic control operations personnel in advance through the Control Center or by local procedures.
