Reportable Occurrences

 

A Reportable Occurrence is an operational event or hazard that meets the criteria defined by the State requiring documentation and/or investigation.

Data Collection

An organization collects factual occurrence information, such as:

  • Occurence type
  • Outcome

An organization collects occurrence causes, such as:

  • Direct Causes
  • Environmental Factors

An organization collects contributing factors, such as:

  • Narrative Data
  • Human factors

From multiple sources a domain collects risk-reduction data such as:

  • Safety recommendations
Data Analysis

An organization processes rate data to identify trends by occurrence type and outcome

A domain calculates the probability of an individual hazard leading to an occurrence

An organization processes data to:

  • Identify the frequency and rate of direct causes
  • Link direct causes to the occurrence outcome (what directly made this happen)
  • Identify the role of a domain in an occurrence (who or what was involved in the occurrence)
  • Begin the identification of risk by aggregating reportable occurrences to identify trends

An organization processes data to:

  • Identify the frequency and rate of contributing factors
  • Link contributing factors to direct causes and to the occurrence outcome (what increased the probability of this outcome)
  • Identify quantitative data relationships to develop a risk baseline (develop a detailed risk picture)
  • Identify qualitative data relationships to improve the understanding of quantitative relationships

An organization processes data to:

  • Proactively identify risk pathways through statistical tests (a set of direct and contributing factors that are likely to lead to a hazard)
  • Identify safety benefits (what preventative measures worked)
  • Develop corrective actions to address global issues
  • Develop and compare safety benchmarks
Data Collaboration

An organization collaborates exclusively within an affected department.

Within an organization the affected department collaborates with another internal department, such as the safety department.

All departments within an organization collaborate amongst one another.

Organizations within a domain collaborate with another organization in a similar or different domain to address global safety needs (e.g. CAST safety enhancement).

Air Accident Investigation Bureau - Singapore

The Air Accident Investigation Bureau - Singapore maintains a database of on-going and completed safety investigations. This link provides access to the investigation reports.

ICAO Accident / Incident Data Reporting (ADREP)

States have access to the ADREP system, which is operated and maintained by ICAO. This interactive database collects occurrence data (accident / incident), and provides users with the ability to exchange safety information. 

Reportable Occurrences - ICAO

ICAO requirements for incident reporting and reporting occurrences.

Mandatory Occurrence Reporting - USA

Mandatory occurrence reporting requirements in the USA are detailed within 14 CFR Part 121 and 49 CFR Part 830. Additionally, individual operators may have internal requirements that exceed regulatory minimums. Sample mandatory occurrence reporting requirements are: 121.565, 121.575, 121.703, 830.5

Immediately Reportable Matters - Australia

Immediately reportable matters are documented in the Transportation Safety Investigation (TSI) Regulations 2003. This information allows investigators the opportunity to preserve evidence, and to act quickly to identify the underlying factors that led to an occurrence. 

Mandatory Occurence Reporting - Singapore

In Singapore, mandatory occurrence reporting is guided by several Air Navigation Orders and guidance materials. Sample reportable occurrences are aircraft equipment malfunctions, procedural violations, or an incident that occurs during the course of training. Reporting and analyzing this information allows CAAS to employ a forward-looking approach to the identification of safety needs.
