The Tupolev Tu-154 (Russian: Tyполев Ту-154; NATO reporting name: "Careless") is a three-engine medium-range narrow-body airliner designed in the mid-1960s and manufactured by Tupolev. A workhorse of Soviet and (subsequently) Russian airlines for several decades, it carried half of all passengers flown by Aeroflot and its subsidiaries (137.5 million/year or 243.8 billion passenger km in 1990), remaining the standard domestic-route airliner of Russia and former Soviet states until the mid-2000s. It was exported to 17 non-Russian airlines and used as a head-of-state transport by the air forces of several countries.
With a cruising speed of 850 kilometres per hour (530 mph) the Tu-154 is one of the fastest civilian aircraft in use and has a range of 5,280 kilometres (3,280 mi). Capable of operating from unpaved and gravel airfields with only basic facilities, it was widely used in the extreme Arctic conditions of Russia's northern/eastern regions where other airliners were unable to operate. Originally designed for a 45,000-hour service life (18,000 cycles) but capable of 80,000 hours with upgrades, it was expected to continue in service until 2016, although noise regulations have restricted flights to western Europe and other regions.
Since 1968 there have been 39 fatal incidents involving the Tu-154, most of which were caused either by factors unrelated to the aircraft, incorrect maintenance, or by its extensive use in demanding conditions. Few of the Tu-154 accidents appear to have involved technical failure.
