Who must act and who is affected

On an obligation the addressee is recorded separately from the party that is merely affected. That difference decides who a supervisory authority addresses and who has work to do without the duty resting on them.

What this object links to

Every relation appears below as a path: from the source with its locator, through the conditions and exceptions of the object carrying the relation, to the consequence. A locator belongs to a statement in the data and not to a relation, so the source is the source anchor of the carrying object.

What this object states

Official fact

Attributable to a named primary source, with a locator. Where they differ, the official source prevails.

Article 73 obliges providers to report serious incidents to the market surveillance authority: immediately after establishing the causal link and at the latest within 15 days, shortened to 10 days in the event of death and to 2 days for widespread infringement or serious disruption of critical infrastructure. Deployers inform the provider without delay.
- Locator: Article 73(1)-(11)praxikon:eu:ai-act:source:reg-eu-2024-1689Open official source
This provision is named in none of the three points of Article 113, third paragraph, and therefore falls under the general application date in the second paragraph: 2 August 2026. The move to 2 December 2027 and 2 August 2028 in point (c) concerns only Chapter III, Sections 1, 2 and 3, with the exception of Article 6(5). When a high-risk AI system that this provision addresses can practically exist is a second question: through Article 6(2) and Annex III that is 2 December 2027, and through Article 6(1) and Annex I 2 August 2028. That practical date sits in high_risk_regime_from and not in deadline_at. This is how decision D1 of 6 September 2026 is recorded; see data/ai-act/review/decision-d1-application-dates.json.

Our interpretation

Our own reading. It can change without the law changing, and it is not the position of a supervisory authority.

The deadlines are too short to design the process during the incident: those who decide who reports at the first incident will not make 15 days, let alone 2. This is the GDPR breach playbook, but for AI.
- Locator: Article 73(1)-(11)praxikon:eu:ai-act:source:reg-eu-2024-1689Open official source

Recommended step

A practical step we consider appropriate. Not an obligation following from the Regulation.

Connect the AI incident process to the existing breach and security process and add the AI-specific definitions and deadlines.

When this applies

1A serious incident occurs with a high-risk system: death or serious harm to health, serious and irreversible disruption of critical infrastructure, infringement of fundamental-rights protections or serious damage to property or environment.

When this does not apply

For systems under sectoral reporting regimes with equivalent duties, reporting may run through that regime to avoid duplication.
