ATM/ANS.OR.A.065 Occurrence reporting

ANNEX III COMMON REQUIREMENTS FOR SERVICE PROVIDERS (Part-ATM/ANS.OR) · Regulation (EU) 2017/373 · EAR revision 12 Mar 2025

IRImplementing rule

ATM/ANS.OR.A.065Occurrence reporting

(a)As part of its management system, the ATM/ANS provider shall establish and maintain an occurrence-reporting system, including mandatory and voluntary reporting. ATM/ANS providers established in a Member State shall ensure that the system complies with the requirements of Regulation (EU) No 376/2014 and Regulation (EU) 2018/1139, as well as with the delegated and implementing acts adopted on the basis of those regulations.

(b)The ATM/ANS provider shall report to the competent authority and to any other organisation required to be informed by the Member State, where the ATM/ANS provider provides its services, any safety-related event or condition that endangers or, if not corrected or addressed, could endanger an aircraft, its occupants or any other person, and in particular any accident or serious incident.

(c)Without prejudice to point (b), the ATM/ANS provider shall report to the competent authority and to the organisation responsible for the design and/or maintenance of the ATM/ANS systems and constituents, if different from the ATM/ANS provider, any malfunction, technical defect, exceedance of technical limitations, occurrence, or other irregular circumstance that has or may have endangered the safety of services and has not resulted in an accident or serious incident.

(d)Without prejudice to Regulation (EU) No 376/2014 and the delegated and implementing acts adopted on the basis thereof, reports shall:

(1)be made as soon as practicable, but in any case within 72 hours after the ATM/ANS provider has become aware of the event or condition to which the report relates, unless exceptional circumstances prevent this;

(2)be made in a form and manner established by the competent authority;

(3)contain all pertinent information about the condition known to the ATM/ANS provider.

(e)For ATM/ANS providers that are not established in a Member State, initial mandatory reports shall:

(1)appropriately safeguard the confidentiality of the identity of the reporter and of the persons mentioned in the report;

(2)be made as soon as practicable, but in any case within 72 hours after the ATM/ANS provider has become aware of the occurrence, unless exceptional circumstances prevent this;

(3)be made in a form and manner established by the competent authority;

(4)contain all pertinent information about the condition known to the ATM/ANS provider.

(f)Without prejudice to Regulation (EU) No 376/2014 and its delegated and implementing acts, where relevant, a follow-up report providing details of actions the organisation intends to take to prevent similar occurrences in the future shall be made as soon as these actions have been identified; those follow-up reports shall:

(1)be sent to the relevant entities initially reported to in accordance with points (b) and (c); and

(2)be made in a form and manner established by the competent authority.

REPORTING RESPONSIBILITIES AND REPORTING PROCEDURES

(a)The ATM/ANS provider should assign one or more suitably qualified persons that has or have clearly defined authority and responsibility to coordinate actions on occurrences and to initiate any necessary further investigation and follow-up activity.

(b)If more than one person is assigned such responsibility, the ATM/ANS provider should identify a single person to act as the main focal point for ensuring a single reporting channel is established to the accountable manager. This should in particular apply to ATM/ANS providers that hold one or more additional organisation certificates within the scope of Regulation (EU) 2018/1139 and its delegated and implementing acts where the occurrence-reporting system is fully integrated with that required under the additional certificate(s) held.

(c)The ATM/ANS provider should establish procedures to be used for reporting to the competent authority and to any other organisation required, which include as a minimum:

(1)a description of the applicable requirements for reporting;

(2)the scope of reporting to other organisations, considering the service provider’s interfaces with other organisations, including organisations contracted in accordance with point ATM/ANS.OR.B.015;

(3)a description of the reporting mechanism, including reporting forms, means and deadlines;

(4)safeguards to ensure the protection of the reporter’s confidentiality and the protection of personal data;

(5)responsibilities of the organisation and personnel involved in the reporting; and

(6)a description of the mechanism and personnel responsibilities for identifying root causes, and the actions that may be needed to be taken to prevent similar occurrences in the future, as appropriate. Such procedures should be included in the organisation’s management system documentation.

MANDATORY REPORTING — GENERAL

(a)For ATM/ANS providers that have their principal place of operation and, if any, their registered office located in a Member State, Commission Implementing Regulation (EU) 2015/1018 of 29 June 2015 lays down a list classifying occurrences in civil aviation to be mandatorily reported according to Regulation (EU) No 376/2014. This list should not be understood as being an exhaustive collection of all issues that may pose a significant risk to aviation safety and, therefore, reporting should not be limited to the items listed in that Regulation and the additional items referred to in point ATM/ANS.OR.A.065(c).

(b)In addition to the reports referred to in point (a), ATM/ANS providers should report volcanic ash clouds, encountered by aircraft operators, of which they have become aware.

REPORTING BETWEEN ORGANISATIONS

(a)The reporting to the organisations defined in point ATM/ANS.OR.A.065 does not affect the need to report to other organisations with which the ATM/ANS provider interfaces, and which might be involved in or be affected by the reported event (e.g. other service providers, including contracted parties in accordance with point ATM/ANS.OR.B.015, involved in an occurrence, aerodrome operators, etc.).

(b)Any ATM/ANS provider that reports to the organisation responsible for the design of the air traffic management (ATM)/air navigation services (ANS) systems and ATM/ANS constituents should actively support any investigations that may be initiated by that organisation. Support should be provided by a timely response to information requests and by making available affected system components or constituents, for the purpose of the investigation, subject to an agreement with the respective system component or constituent owners.

(c)In addition to reporting to the organisation responsible for the design of the ATM/ANS systems and ATM/ANS constituents, if different from the ATM/ANS provider, the ATM/ANS provider may be required to report to the aerodrome operator, to other ATM/ANS providers or air operators.

(d)To ensure effective reporting between organisations, it is important that:

(1)an interface is established between the organisations to ensure that there is an effective and timely exchange of occurrence-related information; and

(2)any relevant safety issue is identified, and it is clearly established which party is responsible for taking further action, if required.

SYSTEMS AND CONSTITUENTS

(a)When determining which failures of systems and constituents are to be reported, a degree of practicality is required as it is not intended that every failure is reported. Only those that have or may have an impact on the safety of the provision of services are reported.

(b)When nothing is defined in European Union or national legislation, the determination of the failures of systems and constituents that need to be reported is done by the service provider and needs to be approved by the competent authority. This determination can be done as a result of an assessment of the installations or changes to the systems and constituents.

(c)The organisation responsible for the design of the systems and constituents may no longer exist or may no longer support the design. In this case, the service provider will have made arrangements to ensure that the safety of the systems and constituents can be assured by appropriate and practical means. In many cases, this means that the service provider has taken over the design responsibilities.

(d)Within the application of Regulation (EC) No 552/2004, the organisation responsible for the design of the constituent will be the entity that signs the Declaration of Conformity or Suitability for use. For systems and constituents which existed before the applicability date of Regulation (EC) No 552/2004, the service provider should identify the responsible organisation, otherwise the service provider should make appropriate arrangements.
