b.
Analysis and interpretation of trends.
c.
The evaluation of repetitive defects.
d.
Confidence testing of expected and achieved results.
e.
Studies of life-bands and survival characteristics.
f.
Reliability predictions.
g.
Other methods of assessment.
6.5.6.3 The range and depth of engineering analysis and interpretation should be related to the particular programme and to the facilities available. The following, at least, should be taken into account:
a.
Flight defects and reductions in operational reliability.
b.
Defects occurring on-line and at main base.
c.
Deterioration observed during routine maintenance.
d.
Workshop and overhaul facility findings.
e.
Modification evaluations.
f.
Sampling programmes.
g.
The adequacy of maintenance equipment and publications.
h.
The effectiveness of maintenance procedures.
i.
Staff training.
j.
Service bulletins, technical instructions, etc.
6.5.6.4 Where the M.A. Subpart G organisation relies upon contracted maintenance and/or overhaul facilities as an information input to the programme, the arrangements for availability and continuity of such information should be established and details should be included.
6.5.7 Corrective Actions.
6.5.7.1 The procedures and time scales both for implementing corrective actions and for monitoring the effects of corrective actions should be fully described. Corrective actions shall correct any reduction in reliability revealed by the programme and could take the form of:
Rev 0, dated 2nd March, 2010
136
Section 2 CAR M
a. Changes to maintenance, operational procedures or techniques.
b. Maintenance changes involving inspection frequency and content, function checks, overhaul requirements and time limits, which will require amendment of the scheduled maintenance periods or tasks in the approved maintenance programme. This may include escalation or de-escalation of tasks, addition, modification or deletion of tasks.
c. Amendments to approved manuals (e.g. maintenance manual, crew manual).
d. Initiation of modifications.
e. Special inspections of fleet campaigns.
f. Spares provisioning.
g. Staff training.
h. Manpower and equipment planning.
Note: Some of the above corrective actions may need the DGCA approval before implementation.
6.5.7.2 The procedures for effecting changes to the maintenance programme should be described, and the associated documentation should include a planned completion
date for each corrective action, where applicable.
6.5.8 Organisational Responsibilities.
The organisational structure and the department responsible for the administration of the programme should be stated. The chains of responsibility for individuals and departments (Engineering, Production, Quality, Operations etc.) in respect of the programme, together with the information and functions of any programme control committees (reliability group), should be defined. Participation of the DGCA should be stated. This information should be contained in the CAME or MOE as appropriate.
6.5.9 Presentation of information to the DGCA.
The following information should be submitted to the DGCA for approval as part of the reliability programme:
