Data Quality

The quality and content of the occurrence reports is determined by Article 7 of Regulation (EU) No 376/2014.

To ensure the quality of occurrence reports and their completeness, before sending them to the CAA, make sure that:

  1. the occurrence reports include at least all of the relevant information as listed in Annex 1 to Regulation (EU) No 376/2014 - LIST OF REQUIREMENTS APPLICABLE TO THE MANDATORY AND VOLUNTARY OCCURRENCE REPORTING SCHEMES:
    • common mandatory data fields (Headline, Responsible Entity, File Number, Occurrence Status, UTC Date, State/Area of Occurrence, Location of Occurrence, Occurrence Class, Occurrence Category, Narrative Language, Narrative, Event Type, Risk classification);
    • specific mandatory data fields.

In case one of the mandatory data is not available for the final results, quote "UNKNOWN" in the field; however, if the data is irrelevant for a specific event, the value "NOT APPLICABLE" shall be quoted in the field.

Sometimes reporting entities are unable to provide all relevant information within the 144 hour (72 + 72) timeframe. Therefore, additional information may be forwarded to us along with the first results of the analysis that you are required to provide within 30 days of the day the reporter sends an occurrence report to its organization or together with the final results of the analysis you are required to provide us with as soon as they are available, but in principle no later than three months after the date of the initial notification of the occurrence.

Check the quality and consistency of the data at all stages of the reporting, during the internal investigation of the event, etc.
