Action required: a) States or International Organizations (IOs) with no member of OVSG to nominate a member or a Point of Contact; b) States or IOs with an existing member to verify their membership
Sir/Madam,
1. I have the honour to advise you of some new developments for the International Civil Aviation Organization (ICAO) Occurrence Validation Study Group (OVSG). The OVSG was formerly known as the Safety Indicators Study Group (SISG) that was established in 2001. Using the ICAO accident/incident data reporting (ADREP) taxonomy, the OVSG reviews and validates the ADREP reports submitted by States in accordance with the reporting requirements in Annex 13 — Aircraft Accident and Incident Investigation. The work of the group is focusing on commercial air transport to produce an agreed dataset of global accidents and serious incidents with validity, reliability and quality.
2. The deliverables of the OVSG enables the Organization to measure the progress made towards the achievement of the goals and targets presented in the ICAO Global Aviation Safety Plan (GASP). It also contributes to the contents in the ICAO Annual Safety Report; and data-driven decision- making such as, the prioritization of the Universal Safety Oversight Audit Programme (USOAP) activities and the development of Standards and Recommended Practices (SARPs) by other ICAO expert groups.
3. The OVSG conducts its work through annual in-person meetings in February and teleconferences at other times, if and when deemed necessary. The post-meeting verification of data and information identified during the validation process at the meetings is conducted through the OVSG members and the Points of Contact (PoC) nominated by States of Occurrence as defined in Annex 13.
4. During its last annual meeting, held in Montreal from 11 to 13 February 2025, the study group agreed to expand the current validation scope from a maximum mass of over 5 700 kg to 2 250 kg, in alignment with the Annex 13 reporting requirements in Chapter 4. Notification and Chapter 7.

ATTACHMENT A to State letter AN6/42 – 25/19 (English only)
TERMS OF REFERENCE FOR THE OCCURRENCE VALIDATION STUDY GROUP (OVSG)
Background
AIG Divisional Meeting/1999 (Recommendation 2/1 – ADREP1 data analysis) recommended establishing a group of experts to develop safety indicators and analyze accident data. It was agreed that one group of experts would carry out both tasks.
Accordingly, the Safety Indicators Study Group (SISG) was established in 2001.
During initial meetings, a general agreement was reached to produce an agreed dataset of accidents and serious incidents. In the SISG/20 meeting in 2020, it was agreed that the name of the group be changed to Occurrence Validation Study Group (OVSG) to better reflect the deliverables of the group.
In support of the Global Aviation Safety Plan (GASP), the validated accident data have been used for safety statistics and safety risk analysis in the ICAO annual safety report. The data are also used in the ICAO Regional Annual Safety Report and other sources, and support other ICAO Export Groups upon request.
Scope The OVSG reviews the minimum data fields including classification, registration, aircraft type, State/area of occurrence, aircraft damage, injury level, number of fatalities, operation type, schedule type and categorization of Annex 13 reportable accidents from the previous year involving airplanes of a maximum mass of MTOW over 5700 2 250 kg, according to ICAO ADREP and CAST/ICAO Common Taxonomy Team (CICTT) taxonomies2.
As available, the OVSG will reviews and classify Annex 13 reportable serious
incidents involving airplanes of a maximum mass of over 2 250 kg. associated with GASP High Risk Categories and will It also updates classification and categorization of accidents during prior years that were previously categorized as UNKNOWN but have subsequently resulted in a final report or an interim report with additional information.
As applicable, the OVSG will cover future-type commercial air transport
operations.
Desired Expertise The group will be composed of experts involved in accident investigation, air safety investigation, safety analysis, safety intelligence, safety reporting system, data science, safety data management and operational safety.
1 Accident and Incident Data Reporting (ADREP) 2 Additional details of the data attributes and classification categories are including in the OVSG operational guidance document.
A-2
Deliverables The OVSG will provide expert support and summary analyses of State reported accident data, and serious incident data as available to other ICAO expert groups, including:
1) Dataset of validated accidents from prior year, along with relevant factual
details for each accident, to be made available through the ICAO ADREP database;
2) Dataset of reviewed serious incidents from prior year to be made available
through the ICAO ADREP database. 3) Summary reviews of completed ADREP report data, if such data is
available;
4) Feedback to ICAO, and to States through ICAO Regional Officers and OVSG Members, regarding the completeness of ADREP reporting and the accuracy of data provided in ADREP reports.
Timelines and working methodologies
The OVSG meets annually in February. The OVSG may, if and when deemed necessary, conduct preliminary reviews of datasets by teleconferences.
Membership The members of the OVSG are nominated by States and international organizations. Members may be assisted by advisers.
Principal references
1. ADREP database; 2. ADREP taxonomy; and
3. CICTT taxonomies
Review and update
The OVSG will periodically review and revise these terms of reference as needed to support use of State reported ADREP data by ICAO Panels and expert user groups.
ATTACHMENT B to State letter AN6/42 – 25/19 (English only)
ICAO ADREP TAXONOMY
The ADREP taxonomy is a set of definitions and descriptions specifically used during the gathering and reporting of accident/incident data to ICAO in accordance with Annex 13 — Aircraft Accident and Incident Investigation reporting requirements. The detail information about ICAO ADREP taxonomy can be found on the ICAO website (https://www.icao.int/safety/airnavigation/AIG/Pages/ADREP-Taxonomies.aspx).

Ref.: AN2/30 – 25/42 15 April 2025 Subject: Launch of the ICAO Accident/Incident Data Reporting (ADREP) System on the new European Coordination Centre for Accident and Incident Reporting System (ECCAIRS 2) Action required: State to a) notify ICAO of ADREP reporting option and b) nominate a focal point and alternate by 10 June 2025 Sir/Madam,
1. I have the honour to inform you of the launch of the International Civil Aviation Organization (ICAO) Accident/Incident Data Reporting (ADREP) System on the new European Coordination Centre for Accident and Incident Reporting System (ECCAIRS 2). This advanced digital platform is designed to assist aviation stakeholders in collecting, reporting and sharing, as well as analyzing, safety data and information to enhance aviation safety worldwide.
2. Annex 13 — Aircraft Accident and Incident Investigation requires States to notify accident and incidents and submit ADREP reports to ICAO. The safety data and information from the ADREP reports supports ICAO with data-driven decision-making on its development of safety initiatives and Standards and Recommended Practices (SARPs). Additionally, the information contributes to the achievement of the goals and targets presented in the ICAO Global Aviation Safety Plan (GASP). The ADREP information is also available to States to assist them in their accident and incident investigation practices, techniques and prevention efforts.
3. ICAO has transitioned the ADREP Reporting System from the retired ECCAIRS 1 to the new web-based ECCAIRS 2 platform. In addition, “ICAOReporting” on the ICAO Secure Portal has been discontinued. This new system offers:
a) user-friendly interface and easy access: simplifies the reporting process with an intuitive design and use of ADREP taxonomy;
b) exclusive view: each State has privacy and control over its own reports;

c) version history: any changes made by ICAO or a State are traceable; and
d) free of charge: no cost for States to use the ICAO ECCAIRS 2 platform for submitting the initial notification and ADREP reports to ICAO.
4. To assist States in meeting the reporting requirements outlined in Annex 13, ICAO offers the following three options for initial notification and submitting ADREP reports:
a) completing the form: submit ADREP reports to ICAO online at https://eccairs.icao.int. This option is free of charge and for reporting to ICAO only;
b) automated transferring: States opting for full ECCAIRS 2 will have their own accident/incident database. This option will require formalizing a Service Agreement between the State and European Union Aviation Safety Agency (EASA); and
c) bridging from a proprietary system to the ICAO ECCAIRS 2: for States with proprietary systems, programmatic translation and connectivity to ECCAIRS 2 taxonomy is possible via built-in ECCAIRS 2 Application Programming Interface (API). This option will require the State to contact EASA for technical support.
5. I kindly invite you, by 10 June 2025, to send your reply to the ICAO Accident Investigation (AIG) section by email to [email protected]:
a) informing which option, as described in paragraph 4, your State prefers; and
b) nominating a focal point and an alternate focal point who will be responsible for managing and submitting ADREP reports through the ECCAIRS 2 platform. Please submit the name, telephone number, email address and a brief description of their background and current position.
Accept, Sir/Madam, the assurances of my highest consideration.

TERMS OF REFERENCE FOR THE OCCURRENCE VALIDATION STUDY GROUP (OVSG)
Background
AIG Divisional Meeting/1999 (Recommendation 2/1 – ADREP1 data analysis) recommended establishing a group of experts to develop safety indicators and analyze accident data. It was agreed that one group of experts would carry out both tasks.
Accordingly, the Safety Indicators Study Group (SISG) was established in 2001.
During initial meetings, a general agreement was reached to produce an agreed dataset of accidents and serious incidents. In the SISG/20 meeting in 2020, it was agreed that the name of the group be changed to Occurrence Validation Study Group (OVSG) to better reflect the deliverables of the group.
In support of the Global Aviation Safety Plan (GASP), the validated accident data have been used for safety statistics and safety risk analysis in the ICAO annual safety report. The data are also used in the ICAO Regional Annual Safety Report and other sources, and support other ICAO Export Groups upon request.
Scope The OVSG reviews the minimum data fields including classification, registration, aircraft type, State/area of occurrence, aircraft damage, injury level, number of fatalities, operation type, schedule type and categorization of Annex 13 reportable accidents from the previous year involving airplanes of a maximum mass of MTOW over 5700 2 250 kg, according to ICAO ADREP and CAST/ICAO Common Taxonomy Team (CICTT) taxonomies2.
As available, the OVSG will reviews and classify Annex 13 reportable serious
incidents involving airplanes of a maximum mass of over 2 250 kg. associated with GASP High Risk Categories and will It also updates classification and categorization of accidents during prior years that were previously categorized as UNKNOWN but have subsequently resulted in a final report or an interim report with additional information.
As applicable, the OVSG will cover future-type commercial air transport
operations.
Desired Expertise The group will be composed of experts involved in accident investigation, air safety investigation, safety analysis, safety intelligence, safety reporting system, data science, safety data management and operational safety.
1 Accident and Incident Data Reporting (ADREP) 2 Additional details of the data attributes and classification categories are including in the OVSG operational guidance document.
A-2
Deliverables The OVSG will provide expert support and summary analyses of State reported accident data, and serious incident data as available to other ICAO expert groups, including:
1) Dataset of validated accidents from prior year, along with relevant factual
details for each accident, to be made available through the ICAO ADREP database;
2) Dataset of reviewed serious incidents from prior year to be made available
through the ICAO ADREP database. 3) Summary reviews of completed ADREP report data, if such data is
available;
4) Feedback to ICAO, and to States through ICAO Regional Officers and OVSG Members, regarding the completeness of ADREP reporting and the accuracy of data provided in ADREP reports.
Timelines and working methodologies
The OVSG meets annually in February. The OVSG may, if and when deemed necessary, conduct preliminary reviews of datasets by teleconferences.
Membership The members of the OVSG are nominated by States and international organizations. Members may be assisted by advisers.
Principal references
1. ADREP database; 2. ADREP taxonomy; and
3. CICTT taxonomies
Review and update
The OVSG will periodically review and revise these terms of reference as needed to support use of State reported ADREP data by ICAO Panels and expert user groups.

ICAO ADREP TAXONOMY
The ADREP taxonomy is a set of definitions and descriptions specifically used during the gathering and reporting of accident/incident data to ICAO in accordance with Annex 13 — Aircraft Accident and Incident Investigation reporting requirements. The detail information about ICAO ADREP taxonomy can be found on the ICAO website (https://www.icao.int/safety/airnavigation/AIG/Pages/ADREP-Taxonomies.aspx).

Ref.: AN2/30 – 25/42 15 April 2025 Subject: Launch of the ICAO Accident/Incident Data Reporting (ADREP) System on the new European Coordination Centre for Accident and Incident Reporting System (ECCAIRS 2) Action required: State to a) notify ICAO of ADREP reporting option and b) nominate a focal point and alternate by 10 June 2025 Sir/Madam,
1. I have the honour to inform you of the launch of the International Civil Aviation Organization (ICAO) Accident/Incident Data Reporting (ADREP) System on the new European Coordination Centre for Accident and Incident Reporting System (ECCAIRS 2). This advanced digital platform is designed to assist aviation stakeholders in collecting, reporting and sharing, as well as analyzing, safety data and information to enhance aviation safety worldwide.
2. Annex 13 — Aircraft Accident and Incident Investigation requires States to notify accident and incidents and submit ADREP reports to ICAO. The safety data and information from the ADREP reports supports ICAO with data-driven decision-making on its development of safety initiatives and Standards and Recommended Practices (SARPs). Additionally, the information contributes to the achievement of the goals and targets presented in the ICAO Global Aviation Safety Plan (GASP). The ADREP information is also available to States to assist them in their accident and incident investigation practices, techniques and prevention efforts.
3. ICAO has transitioned the ADREP Reporting System from the retired ECCAIRS 1 to the new web-based ECCAIRS 2 platform. In addition, “ICAOReporting” on the ICAO Secure Portal has been discontinued. This new system offers:
a) user-friendly interface and easy access: simplifies the reporting process with an intuitive design and use of ADREP taxonomy;
b) exclusive view: each State has privacy and control over its own reports;

c) version history: any changes made by ICAO or a State are traceable; and
d) free of charge: no cost for States to use the ICAO ECCAIRS 2 platform for submitting the initial notification and ADREP reports to ICAO.
4. To assist States in meeting the reporting requirements outlined in Annex 13, ICAO offers the following three options for initial notification and submitting ADREP reports:
a) completing the form: submit ADREP reports to ICAO online at https://eccairs.icao.int. This option is free of charge and for reporting to ICAO only;
b) automated transferring: States opting for full ECCAIRS 2 will have their own accident/incident database. This option will require formalizing a Service Agreement between the State and European Union Aviation Safety Agency (EASA); and
c) bridging from a proprietary system to the ICAO ECCAIRS 2: for States with proprietary systems, programmatic translation and connectivity to ECCAIRS 2 taxonomy is possible via built-in ECCAIRS 2 Application Programming Interface (API). This option will require the State to contact EASA for technical support.
5. I kindly invite you, by 10 June 2025, to send your reply to the ICAO Accident Investigation (AIG) section by email to [email protected]:
a) informing which option, as described in paragraph 4, your State prefers; and
b) nominating a focal point and an alternate focal point who will be responsible for managing and submitting ADREP reports through the ECCAIRS 2 platform. Please submit the name, telephone number, email address and a brief description of their background and current position.
Accept, Sir/Madam, the assurances of my highest consideration.
