In its report on the accident, published in July 2002, the Aircraft and Railway Accidents Investigation Commission called on the International Civil Aviation Organization (ICAO) to make it clear that TCAS advisories should always take precedence over ATC instructions. A similar recommendation was made three months later by Germany's accident investigation body (the BFU) in light of the 2002 Überlingen mid-air collision. ICAO accepted these recommendations and amended its regulations in November 2003.Flight Safety Digest, March 2004 "Deadly Crossroads," Mayday
