Investigation Reports

The RCAF / DFS has launched their newly restructured website, based on the Government of Canada’s Standard on Web Usability. We are striving to have the Investigation reports and other important Flight Safety information back online as soon as possible.  Until they are available, please contact DFS (dfs.dsv@forces.gc.ca) if you require any specific information.

Flight Safety reports are produced under the authority of the Minister of National Defence pursuant to Section 4.2 of the Aeronautics Act, and in accordance with A‑GA‑135‑001/AA‑001, Flight Safety for the Canadian Forces.

The FS reports are prepared solely for the purpose of accident prevention and shall not be used for legal, administrative, or disciplinary action. Although most investigations are performed at the wing level by the Wing or Unit Flight Safety Officer, more significant occurrences will be investigated by DFS, in accordance with regulations.

Information: Investigation Report Types

At the wing level, following the notification of a FS occurrence, Supplementary Reports are produced for minor or non-complex incidents, once the investigation by the Wing or Unit Flight Safety Officer is completed. Those reports are not made public and, therefore, not published on the DFS website.

In the case of occurrences investigated by DFS, the investigation will usually be classified as a Class I, or Class II, investigation depending on the aircraft damage level, the personnel casualty level, and the safety of flight compromise level.

DFS will document their investigation results in one of the following reports, depending on the class level:

  • For Class I or Class II level investigations (investigations of aircraft accidents and serious incidents): From the Investigator (FTI), Flight Safety Investigation Report (FSIR) and Epilogue;
  • For selected Class II or Class III level investigations (occurrences that are sufficiently complex to warrant a more thorough investigation than a normal Supplementary Report produced at the wing level, but that do not require the same degree of scrutiny that is required for Class 1): Enhanced Supplementary Report (ESR) and Epilogue.

From the Investigator (FTI)

The FTI summarizes information contained in the preliminary report issued by the investigation team after it completes the first phase of its work. Subject to the requirements for operations security, this summary will describe factual information and immediate safety actions taken, and provide an indication of the direction in which the investigation is proceeding.

The FTI is usually made public and posted on the DFS website within five weeks of the incident.

Flight Safety Investigation Report (FSIR)

Once the investigation is complete, the final FSIR is prepared. This is a comprehensive report on a specific flight safety occurrence that includes recommendations for preventive measures.  The report will contain all conclusions and recommendations associated with the occurrence. It contains four sections - facts, analysis, conclusions and preventive measures - and is released to the public under the authority of the Director of the DFS.

The report closely parallels the internationally accepted International Civil Aviation Organization (ICAO) format.

The Report’s recommended preventive measures are provided to the chain of command and applicable action organizations for their consideration.  DFS has no executive authority to direct the implementation of the preventive measures.  If the investigation team uncovers information that the aviation community needs to be made aware of immediately, this information is communicated without delay.

The FSIR is usually posted on the DFS website within 12 to 18 months of the incident, depending on the complexity of the investigation.

Epilogue

The Epilogue summarizes the information contained in the FSIR. The Epilogue is made public and usually posted on the DFS website at the same time as the FSIR.

Enhanced Supplementary Report (ESR) and Epilogue

The ESR is to be used for Class II or selected Class III level investigations. The reporting requirements are the same as for the Supplementary Report (30 days) except that the investigation paragraph will be more detailed. This report will not be released to the public.

Once the Class II level investigation is closed, an Epilogue will be made public and posted on the DFS website, usually within six to 12 months from the incident.
