About IORS

The Internal Occurrence Reporting System is the system that the Agency uses to process all safety related occurrences reported to EASA.
In general, IORS brings no changes to obligations and responsibilities of reporting entities/organisations (e.g. certificate or approval holders) and the Member States (National Aviation Authorities (NAA)). They retain the same responsibilities to act and make follow-up actions on occurrences as before.
As there is no change in the legislation due to the introduction of the IORS, there is no change in the scope of occurrences that shall be reported to the Agency.
However, there have been some technical changes in the manner in which reports are delivered to the Agency. Basically, these changes have involved the establishment of data bridges for top reporting organisations and electronic reporting forms for all other reporting entities and NAAs. For further information on reporting obligations please consult the FAQ tab. To access IORS Report Forms please click here.

Other texts of interest concerning occurrence reporting:

Other reporting obligations exist (not for reporting to EASA) like Directive 2003/42, implemented by Regulation 1321/2007 and Regulation 1330/2007. According to Regulation 996/2010 EASA is entitled to access that information

Notifying accidents and serious incidents:

Regulation 996/2010 states obligations to notify accidents and incidents to EASA (transposing ICAO Annex 13 standards and recommended practices related to notification).

The IORS management system:

The IORS management system is established via Internal Occurrence Reporting System policy and it defines the roles and main tasks within the Internal Occurrence Reporting System for the IORS Department, Certification, Approvals & Standardisation, Rulemaking Directorates, and the Information Services Department.
