context_page_description: The Boeing 767 is a wide-body airliner developed and manufactured by Boeing Commercial Airplanes.
  The airliner was launched as the 7X7 project on July 14, 1978, the prototype first flew on September 26, 1981, and it was certified on July 30, 1982.
  The original 767-200 entered service on September 8 with United Airlines, and the extended-range 767-200ER in 1984.
  It was stretched into the 767-300 in October 1986, followed by the 767-300ER in 1988, the most popular variant.
  The 767-300F, a production freighter version, debuted in October 1995.
  It was stretched again into the 767-400ER from September 2000.
  To complement the larger 747, it has a seven-abreast cross-section, accommodating smaller LD2 ULD cargo containers.
  The 767 is Boeing's first wide-body twinjet, powered by General Electric CF6, Rolls-Royce RB211, or Pratt & Whitney JT9D turbofans. JT9D engines were eventually replaced by PW4000 engines.
  The aircraft has a conventional tail and a supercritical wing for reduced aerodynamic drag.
  Its two-crew glass cockpit, a first for a Boeing airliner, was developed jointly for the 757 − a narrow-body aircraft, allowing a common pilot type rating.
context_section_description: As of February 2019, the Boeing 767 has been in 60 aviation occurrences, including 19 hull-loss accidents. Seven fatal crashes, including three hijackings, have resulted in a total of 854 occupant fatalities.
  The 767's first incident was Air Canada Flight 143, a 767-200, on July 23, 1983. The airplane ran out of fuel in-flight and had to glide with both engines out for almost 43 nautical miles (80 km) to an emergency landing at Gimli, Manitoba, Canada. The pilots used the aircraft's ram air turbine to power the hydraulic systems for aerodynamic control. There were no fatalities and only minor injuries. This aircraft was nicknamed "Gimli Glider" after its landing site. The aircraft, registered C-GAUN, continued flying for Air Canada until its retirement in January 2008.
  The airliner's first fatal crash, Lauda Air Flight 004, occurred near Bangkok on May 26, 1991, following the in-flight deployment of the left engine thrust reverser on a 767-300ER; none of the 223 aboard survived; as a result of this accident all 767 thrust reversers were deactivated until a redesign was implemented. Investigators determined that an electronically controlled valve, common to late-model Boeing aircraft, was to blame. A new locking device was installed on all affected jetliners, including 767s.
  On October 31, 1999, EgyptAir Flight 990, a 767-300ER, crashed off Nantucket, Massachusetts, in international waters killing all 217 people on board. The United States National Transportation Safety Board (NTSB) concluded "not determined", but determined the probable cause to be due to a deliberate action by the first officer; Egypt disputed this conclusion.
  On April 15, 2002, Air China Flight 129, a 767-200ER, crashed into a hill amid inclement weather while trying to land at Gimhae International Airport in Busan, South Korea. The crash resulted in the death of 129 of the 166 people on board, and the cause was attributed to pilot error.
  The 767 has been involved in six hijackings, three resulting in loss of life, for a combined total of 282 occupant fatalities. On November 23, 1996, Ethiopian Airlines Flight 961, a 767-200ER, was hijacked and crash-landed in the Indian Ocean near the Comoro Islands after running out of fuel, killing 125 out of the 175 persons on board; survivors have been rare among instances of land-based aircraft ditching on water. Two 767s were involved in the September 11 attacks on the World Trade Center in 2001, resulting in the collapse of its two main towers. American Airlines Flight 11, a 767-200ER, crashed into the North Tower, killing all 92 people on board, and United Airlines Flight 175, a 767-200, crashed into the South Tower, with the death of all 65 on board. In addition, more than 2,600 people were killed in the towers or on the ground. A foiled 2001 shoe bomb attempt that December involved an American Airlines 767-300ER.
  On November 1, 2011, LOT Polish Airlines Flight 16, a 767-300ER, safely landed at Warsaw Chopin Airport in Warsaw, Poland after a mechanical failure of the landing gear forced an emergency landing with the landing gear retracted. There were no injuries, but the aircraft involved was damaged and subsequently written off. At the time of the incident, aviation analysts speculated that it may have been the first instance of a complete landing gear failure in the 767's service history. Subsequent investigation determined that while a damaged hose had disabled the aircraft's primary landing gear extension system, an otherwise functional backup system was inoperative due to an accidentally deactivated circuit breaker.
  In January 2014, the U.S. Federal Aviation Administration issued a directive that ordered inspections of the elevators on more than 400 767s beginning in March 2014; the focus was on fasteners and other parts that can fail and cause the elevators to jam. The issue was first identified in 2000 and has been the subject of several Boeing service bulletins. The inspections and repairs are required to be completed within six years. The aircraft has also had multiple occurrences of "uncommanded esc
