ANNEX I - Continuing Airworthiness Requirements

CAA shall have a process in place to analyse findings for their safety significance.
(e) The CAA shall record all findings and closure actions.
(f) If during aircraft surveys evidence is found showing non-compliance with this Part or with
any other Part, the finding shall be dealt with as prescribed by the relevant Part.
(g) If so required to ensure appropriate enforcement action, the CAA shall exchange
information on non-compliances identified in accordance with point (f) with other
competent authorities.
M.B.303(a) AMC1 Aircraft continuing airworthiness monitoring (ACAM)
ACAM SURVEY PROGRAMME — SCOPE
1. The CAA should establish a programme covering in-depth surveys and ramp surveys.
2. The CAA’s survey programme should select aircraft and/or operators depending on the
number and complexity of aircraft on the national register, the diversity of aircraft types,
local knowledge of the maintenance environment and operating conditions, airworthiness
standards and past surveillance experience.
3. The programme should prioritise the operator/fleet/aircraft/key risk elements which are
causing the greatest concern.
4. The survey programme should also include a certain percentage of unannounced ramp
surveys.
5. The survey programme and changes thereto should be documented.
M.B.303(a) AMC2 Aircraft continuing airworthiness monitoring (ACAM)
ACAM SURVEY PROGRAMME — CREDITING
1. Where the ACAM survey can be linked to the oversight of an approved organisation, then
credit can be granted in the monitoring process of that approved organisation.
2. The CAA may take credit of aircraft airworthiness inspections qualifying for the ACAM
programme when these inspections are performed in accordance with the provisions of
Regulation (EU) 2018/1139 and its implementing and delegated acts.

COMBINED SURVEYS
In the interest of efficient use of CAA resources, aircraft inspection procedures may be established
covering the combined scope of various aircraft survey tasks performed by a CAA, such as but not
limited to:
- ACAM indepth survey;
- airworthiness review;
- permit to fly physical inspection;
- Export Certificate of Airworthiness inspection;
- product survey in accordance with M.B.704(c);
- product audit in accordance with Part145, PartCAO or PartM Subpart F;
- review under supervision for airworthiness review staff authorisation, provided it covers
the full scope of the physical survey in accordance with M.A.710(c); and
- ramp inspections performed in accordance with ARO.OPS [1] or ARO.RAMP [2].
Depending on which type of survey is required, any actual survey performed may cover a subset of
the combined scope.

SCOPE OF SURVEYS
1. The CAA 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).
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.
3. When performing a ramp survey, the inspector(s) should make all possible efforts to avoid
an unreasonable delay of the aircraft inspected.
4. The further information on ‘KEY RISK ELEMENTS’ can be found in Appendix III to GM1
M.B.303(b).
