1.5.1.2 The extent of the objectives should be directly related to the scope of the programme. Its scope could vary from a component defect monitoring system for a small M.A.Subpart G organisation, to an integrated maintenance management programme for a big M.A.Subpart G organisation. The manufacturer’s maintenance planning documents may give guidance on the objectives and should be consulted in every case.
1.5.1.3 In case of a MSG-3 based maintenance programme, the reliability programme should provide a monitor that all MSG-3 related tasks from the maintenance programme are effective and their perio-dicity is adequate.
6.5.2 Identification of items.
The items controlled by the programme should be stated, e.g. by ATA Chapters. Where some items (e.g. aircraft structure, engines, APU) are controlled by separate programmes, the associated procedures (e.g. indi-vidual sampling or life development programmes, constructor’s structure sampling programmes) should be cross referenced in the programme.
6.5.3 Terms and definitions.
The significant terms and definitions applicable to the Programme should be clearly identified. Terms are already defined in MSG-3, Part-145 and Part-M.
6.5.4 Information sources and collection.
6.5.4.1 Sources of information should be listed and procedures for the transmission of information from the sources, together with the procedure for collecting and receiving it, should be set out in detail in the CAME or MOE as appropriate.
6.5.4.2 The type of information to be collected should be related to the objectives of the Programme and should be such that it enables both an overall broad based assessment of the information to be made and also allow for assessments to be made as to whether any reaction, both to trends and to individual events, is neces-sary. The following are examples of the normal prime sources:
(a)
Pilots Reports.
(b)
Technical Logs.
(c)
Aircraft Maintenance Access Terminal / On-board Maintenance System readouts.
(d)
Maintenance Worksheets.
(e)
Workshop Reports.
(f)
Reports on Functional Checks.
(h)
Reports on Special Inspections
(g)
Stores Issues/Reports.
(i)
Air Safety Reports.
(j)
Reports on Technical Delays and Incidents.
(k)
Other sources: ETOPS, RVSM, CAT II/III.
6.5.4.3 In addition to the normal prime sources of information, due account should be taken of continuing airworthiness and safety information promulgated under Part-21
6.5.5 Display of information.
Collected information may be displayed graphically or in a tabular format or a combination of both. The rules governing any separation or discard-ing of information prior to incorporation into these formats should be stated. The format should be such that the identification of trends, specific highlights and related events would be readily apparent.
6.5.5.1 The above display of information should include provisions for “nil returns” to aid the examination of the total information.
6.5.5.2 Where “standards” or “alert levels” are included in the pro-gramme, the display of information should be oriented accord-ingly.
6.5.6 Examination, analysis and interpretation of the information.
The method employed for examining, analysing and interpreting the pro-gramme information should be explained.
6.5.6.1 Examination.
Methods of examination of information may be varied according to the content and quantity of information of individual pro-grammes. These can range from examination of the initial indica-tion of performance variations to formalised detailed procedures at specific periods, and the methods should be fully described in the programme documentation.
