(b) This verification shall: (1) be supported by documentation specifically intended to provide personnel responsible for safety oversight with guidance to perform their functions; (2) provide the aerodrome operators and providers of [apron](https://avioverse.aero/glossary/easa/apron) management services concerned with the results of safety oversight activity; (3) be based on audits and inspections, including unannounced inspections, where appropriate; and (4) provide the Competent Authority with the evidence needed in case further action is required, including the measures foreseen by ADR.AR.C.055. (c) The scope of oversight shall take into account the results of past oversight activities and the safety priorities identified. (d) The Competent Authority shall collect and process any information deemed useful for oversight, including unannounced inspections, as appropriate. (e) Within its oversight powers, the Competent Authority may decide to require prior approval for any obstacles, developments and other activities within the areas monitored by the [aerodrome operator](https://avioverse.aero/glossary/easa/aerodrome-operator) in accordance with ADR.OPS.B.075, which may endanger safety and adversely affect the operation of an aerodrome. (f) With regard to the certification and oversight of the organisation’s compliance with point ADR.OR.D.005A, in addition to complying with points (a) to (e) of this point, the competent authority shall review any approval granted under point IS.D.OR.200(e) of the Annex to Delegated Regulation (EU) 2022/1645 following the applicable oversight [audit](https://avioverse.aero/glossary/easa/audit) cycle and whenever changes are implemented in the scope of work of the organisation. IR · ADR.AR.C.005 — Regulation (EU) No 139/2014 · Regulation (EU) 2025/2293 · Aerodromes Easy Access Rules · EAR revision 13 Mar 2026 AMC Acceptable means of compliance ## AMC1 ADR.AR.C.005 Oversight GENERAL (a) The [Competent Authority](https://avioverse.aero/glossary/easa/competent-authority) should assess the [aerodrome operator](https://avioverse.aero/glossary/easa/aerodrome-operator), and monitor its continued competence to conduct safe operations in compliance with the applicable requirements and the certification basis. Similarly, the Competent Authority should monitor the continued competence of providers of [apron](https://avioverse.aero/glossary/easa/apron) management services. The Competent Authority should ensure that accountability for assessing and monitoring [aerodrome](https://avioverse.aero/glossary/easa/aerodrome) operators, as well as providers of apron management services, is clearly defined. This accountability may be delegated or shared, in whole or in part. (b) It is essential that the Competent Authority has the full capability to adequately assess the continued competence of an aerodrome operator, or a provider of apron management services by ensuring that the whole range of activities is assessed by appropriately qualified personnel. AMC · AMC1 ADR.AR.C.005 — Regulation (EU) No 139/2014 · ED Decision 2014/012/R · Aerodromes Easy Access Rules · EAR revision 13 Mar 2026 GM Guidance material ## GM1 ADR.AR.C.005 Oversight GENERAL (a) Responsibility for the safe operation of an [aerodrome](https://avioverse.aero/glossary/easa/aerodrome) lies with the [aerodrome operator](https://avioverse.aero/glossary/easa/aerodrome-operator). Under these provisions, a positive move is made towards devolving upon the aerodrome operator a share of the responsibility for monitoring the safety of operations. The objective cannot be attained unless aerodrome operators are prepared to accept the implications of this policy, including that of committing the necessary resources to its implementation. Crucial to success of the policy is the content of Part-ADR.OR which requires the establishment of a management system by the aerodrome operator. (b) The [Competent Authority](https://avioverse.aero/glossary/easa/competent-authority) should continue to assess the aerodrome operator’s or [apron management service](https://avioverse.aero/glossary/easa/apron-management-service) provider’s compliance with the applicable requirements, including the effectiveness of its management system. If their management system is judged to have failed in its effectiveness, then this in itself is a breach of the requirements which may, among others, call into question the validity of the certificate or declaration, if applicable. (c) The accountable manager is accountable to the Competent Authority as well as to those who may appoint him/her. It follows that the Competent Authority cannot accept a situation in which the accountable manager is denied sufficient funds, manpower, or influence to rectify deficiencies identified by the management system.
