text: 1. In AMC M.B.303 (b), now AMC1 M.B.303(b), the order of the subparagraphs is changed and the text is amended as follows: AMC1 M.B.303(b) Aircraft continuing airworthiness monitoring (*) SCOPE OF SURVEYS 2.1. The competent authority should undertake sample product surveys of aircraft on its register to verify that: (a) the condition of an aircraft as sampled is to a standard acceptable for the Certificate of Airworthiness/Airworthiness Review Certificate to remain in force, (b) the operator/owner’s management of the airworthiness of the aircraft is effective, (c) the approvals and licenses granted to organisations and persons continue to be applied in a consistent manner to achieve the required standards. A physical inspection of the aircraft is necessary during each ACAM survey (ramp or in-depth). 1.2. Sample product surveys of aircraft include: (a) in-depth surveys carried out during extensive maintenance that fully encompass selected aspects of an aircraft’s airworthiness, (b) ramp surveys carried out during aircraft operations to monitor the apparent condition of an aircraft’s airworthiness. (c) in-flight surveys, as deemed necessary by the competent authority. 3. When performing a ramp survey, the inspector(s) should make all possible efforts to avoid an unreasonable delay of the aircraft inspected. 2. A new AMC2 is added for M.B.303(b), it incorporates elements from AMC M.B.303(d), which is deleted. AMC2 M.B.303(b) Aircraft continuing airworthiness monitoring IN-DEPTH SURVEY 1. An ACAM in-depth survey is a sample inspection of the key risk elements (KREs) and should be performed during scheduled/extensive maintenance. Appendix III to GM 1 to M.B.303(b) provides guidance on KREs that can be used for planning and/or analysis of the inspections. 2. The survey should be a ‘deep cut’ through the elements or systems selected. 3. The record of an ACAM inspection should identify which KREs were inspected. 3. A new AMC is added for M.B.303(b): AMC3 M.B.303(b) Aircraft continuing airworthiness monitoring* KEY RISK ELEMENTS 1. The following KREs should be used for aircraft continuing airworthiness monitoring: (a) Type design and changes to type design (b) Airworthiness limitations (c) Airworthiness Directives

text: Annex to ED Decision 2013/005/R

text: (d) Aircraft documents (e) Flight Manual (f) Mass & Balance (g) Markings & placards (h) Operational requirements (i) Defect management (j) Aircraft Maintenance Programme (k) Component control (l) Repairs (m) Records 2. These KREs and their detailed components should be adapted to the complexity of the aircraft type being surveyed by retaining only those items that are applicable and relevant for the particular aircraft type. 4. New GM is added for M.B.303(b): GM1 M.B.303(b) Aircraft continuing airworthiness monitoring* KEY RISK ELEMENTS The KREs define the scope of continuing airworthiness. The list of KREs is intended to provide the basis for planning and control of the ACAM survey programme. It will ensure that the programme covers all aspects of continuing airworthiness. While it is not required to cover all KREs during a given inspection, the ACAM survey programme needs to ensure that there is no omission, i.e. certain KRE are never inspected. * See Appendices to Part-M - Appendix III to GM 1 M.B.303(b) 5. AMC M.B.303(d) is deleted, it is replaced by the new AMC2 to M.B.303(b) and new GM 1 to M.B.303(b). AMC M.B.303 (d) Aircraft continuing airworthiness monitoring 1. Appendix III to this AMC is an example format for an annual in depth survey programme. A sample of the 14 key risk airworthiness elements identified on the example should be assessed during each survey and the survey should include the aircraft as the product sample. The survey should be a ‘deep cut’ through the elements or systems selected and all findings should be recorded. Surveyors/inspectors in conjunction with the owners, operators and maintenance organisations should identify the root cause of each confirmed finding. 2. In addition, an annual ramp survey programme should be developed based on geographical locations, taking into account airfield activity, and focusing on key issues that can be surveyed in the time available without unnecessarily delaying the aircraft. 3. Surveyors/inspectors should be satisfied that the root cause found and the corrective actions taken are adequate to correct the deficiency and to prevent re-occurrence. 4. Where the aircraft continuing airworthiness monitoring survey visit can be linked to the oversight of an approved organisation then credit can be taken in the monitoring process of that approved organisation. 6. Appendix III to AMC M.B.303(d) is renumbered ‘Appendix III to GM1 M.B.303(b)’ and replaced by the following document:

text: C.3 Repairs All repairs and unrepaired damage/degradations need to comply with the instructions of the appropriate maintenance manual (e.g. the SRM, the AMM, the CMM) . With the exception of repairs contained in the certification specifications referred to in Part 21 point 21A.90B or 21A.431B of the Annex (Part 21), all repairs not defined in the appropriate maintenance manual need to be appropriately approved and recorded with the reference to the approval. This includes any damage or repairs to the aircraft/engine(s)/propeller(s), and their components.

Sample embodied repairs to The repair status should identify the repair file reference, the check their conformity against the repair files (physical survey). repair classification, the repaired item (i.e. aircraft/engine/propeller/component, and a precise location if necessary), and the date and total life in FH/FC accumulated by the item at the time of repair or finding of the un-repaired damage/degradations. Cross-reference to the aircraft maintenance programme should also be included, as necessary. Depending on the product State of Design, Bilateral Agreements and/or Agency Decisions on acceptance of certification findings exist and should be taken into account for the determination of acceptable data for repairs.
