Air transportation safety concerns and advisories

Safety concerns provide a marker to the industry and the regulator that the Board has identified a safety deficiency for which it does not yet have sufficient information to make a recommendation. As more data and analysis becomes available, and if the safety deficiency is found to be systemic and not redressed, the safety concern may lead to a recommendation. Safety concerns are usually communicated in final investigation reports.

Safety advisory letters are concerned with safety deficiencies that pose low to medium risks, and are used to inform regulatory or industry stakeholders of unsafe conditions. A safety advisory letter suggests remedial action to reduce risks to safety.
