- The airline is registered in the U.S.
- The specific aircraft involved is registered in the U.S.
For instance, if a Boeing aircraft crashes abroad, given that Boeing is based in the U.S., the NTSB will participate. This also applies to foreign operators with planes registered in the U.S., or if a U.S.-registered airline experiences an accident overseas.
In these cases, provided that the foreign state where the accident occurred is a signatory of the Chicago Convention, it must notify the NTSB to initiate its participation. However, during such investigations, "the foreign state remains the primary authority," controlling information release.
The NTSB appoints an 'Accredited Representative' and technical advisors for these investigations. These advisors may include members from entities like GE Aerospace or other relevant bodies such as South Korea's Aviation and Railway Accident Investigation Board (ARAIB), as seen after Jeju Air flight 7C2216's crash.
The responsibilities of NTSB representatives include identifying "safety deficiencies" affecting U.S. interests and integrating safety lessons to prevent future accidents domestically while facilitating "credible and comprehensive" investigations.
Under ICAO regulations, appointed representatives are entitled to several privileges during their involvement in a foreign investigation: visiting accident scenes, accessing evidence promptly, participating in technical briefings and progress meetings, obtaining witness information, receiving document copies, and making media statements.
States with affected citizens can appoint experts who can visit accident scenes and receive updates if fatalities or serious injuries occur among their nationals.
Air crash investigations involve collecting evidence, analyzing it thoroughly over months or years due to their complexity before compiling final reports with safety recommendations aimed at improving industry practices globally.
The NTSB operates with nearly $150 million annually from federal funding supporting around 400 employees across various offices nationwide.
