On April 10, 2010, about 0656 Coordinated Universal Time (UTC), a Tupolev Tu-154M, Tail Number 101, operated by the Polish Air Force as flight PLF101, crashed during approach to the Military Aerodrom Smolensk "Severnyi", Russia. All 89 passengers and 7 flightcrew were killed, including the President of Poland. The airplane was destroyed by impact and postcrash fire. Following the accident, the governments of the Russian Federation and the Republic of Poland concluded a bilateral agreement that the regional international independent safety investigation organization, the Interstate Aviation Committee (IAC), would conduct the investigation. Although the airplane was operated as a "state" aircraft, by the mutual agreement, the investigation was conducted following the guidance provided in ICAO Annex 13 Standards and Recommended Practices. As the United States was state of design and manufacture for the TAWS and FMS units, the NTSB was requested to support the investigation activity.
