Incident Notification and International Cooperation On May 1, 2020, the government of the Republic of Korea notified the U.S. National Transportation Safety Board (NTSB) of an accident involving a Sikorsky S76 helicopter. In accordance with ICAO Annex 13, the NTSB appointed a U.S. Accredited Representative to assist the Korean government in its investigation of the incident. This appointment reflects the standard international framework for aviation safety investigations, where the state of occurrence leads the inquiry while other involved states may provide technical support. The NTSB's role in this case is limited to assisting the primary investigating authority, ensuring that the process adheres to established international standards. ## Information Release and Jurisdiction The source explicitly states that all investigative information related to this accident will be released by the government of the Republic of Korea. This underscores the principle that the state of occurrence retains primary responsibility for the investigation and the dissemination of its findings.

The focus remains on the formal notification and the appointment of the accredited representative to support the ongoing investigation.
