4. ASSESSMENT METHODOLOGY

4.1 Assessment should result in sufficient information to address continued sustainment and operational capability for the remainder of the expected life of the antenna asset. A quality assessment should address areas pertaining to antenna performance, corrosion, concrete conditions that impact safety and structural integrity, and Grounding, Bonding, Shielding and Lightning

Protection (GBSLP).

4.2 Assessors shall use guidance from TIA-222-G, original equipment manufacture’s (OEM) manuals

(technical, installation, operations), FAA AC 70-7460-1L for instructions for Obstruction

Lighting/Marking, AFI 91-202 mishap/OSHA, MIL-STD-188-124B, MIL-HDBK-419A and antenna specific HFGCS Standard Drawings. The assessor shall also incorporate commercial best practice and commercial standards into his assessment such as American Standard for Testing and

Materials (ASTM) for corrosion and concrete integrity. Local ordinances shall also be addressed.

4.3 In performance of the assessment actions listed in this section, the assessor shall identify parts, materials, skillsets of required laborers, and an estimate of the labor hours of each skillset needed to perform the recommended corrective action (repairs) for each identified discrepancy.

4.4 All tables in this section (numbered 4.x) collectively provide the minimum set of assessment actions required to obtain the necessary information to provide a quality assessment of each stated antenna type/model. Each table addresses a particular antenna model or type of antenna. The assessor shall augment these tasks in order to substantiate recommendations and to ensure compliance with local ordinances.

4.5 Assessment of transmit and receive facilities are covered in each of the antenna checklists.

Grounding, compressor-dehydrator and other facility items are addressed on a per-antenna basis.

SECTION V

5. MAINTENANCE ASSESSMENT REPORT QUALITY

5.1 The quality of the maintenance assessment report will be gauged on addressing each of the elements listed in this section. This includes each of the elements within the tables of this section that apply to the each of the antennas models or types (e.g. TCI Model 521 is addressed in Table 5.1) being assessed. Tables in this section for antenna model or types not included in the set of antennas identified for assessment will not be used to gage maintenance assessment report quality.

5.2 The maintenance assessment report shall clearly address each element listed in this section whether or not it is found in an acceptable state. Acceptable elements for each antenna model/type may be discussed within the report in a consolidated format.

5.3 Identified discrepancies within the maintenance assessment report shall contain the following:

5.3.1 Each identified discrepancy shall contain sufficient basic information to justify the recommended repair. Photographic evidence shall be provided.

5.3.2 The maintenance assessment report shall identify parts, materials, skillsets of required laborers, and an estimate of the labor hours of each skillset needed to perform recommended corrective action (repair) for each identified discrepancy or group of discrepancies.

5.3.3 Discrepancies within transmit or receive facility shall be addressed on a per-antenna basis (e.g. compressor-dehydrator, coaxial cable grounding kits, surge suppression).

5.4 All tables in this section (number 5.x) form a basis of quality elements that shall be addressed within the assessment report. Each table addresses a particular antenna model or type of antenna, and only that particular table which matches the antenna models or types being addressed by the maintenance assessment report will be used to gage the quality of the maintenance assessment report with regards to that specific antenna.

NOTE: Identification (ID) numbers listed within tables of this section (Tables 5.x) coincide with the IDs listed in Section 4 (Tables 4.x). There are some purposely skipped IDs within this section that do not apply to gaging the maintenance assessment report quality, but consistency is maintained.
