On January 25, 2002, at 0243 Alaska standard time, an Airbus Industrie A-340-300 airplane, B-18805, was cleared for takeoff on runway 32 from the Ted Stevens Anchorage International Airport, Anchorage, Alaska. The airplane, call sign Dynasty 011, subsequently departed from a taxiway. The airplane was being operated as an instrument flight rules (IFR) scheduled international passenger flight under Title 14, CFR Part 129, when the incident occurred. The airplane was operated as Flight 011, by China Airlines, Taiwan. The three cockpit crew members, 12 cabin crew members, and 237 passengers, were not injured. The airplane was not damaged. Visual meteorological conditions prevailed. An IFR flight plan was filed from Anchorage to the Chiang Kai-shek International Airport, Taipei, Taiwan.

The National Transportation Safety Board (NTSB) investigator-in-charge (IIC) was notified of the takeoff incident at 0800, by Federal Aviation Administration (FAA) personnel. Information received from the FAA indicated the incident airplane began to taxi for takeoff from the gate area of the north terminal for runway 32. The airplane proceeded southbound on taxiway Romeo, and made a right turn from Romeo onto taxiway Kilo.

The incident airplane was cleared for takeoff on runway 32 by the Anchorage Air Traffic Control Tower (ATCT) local controller as the airplane made the right turn from taxiway Romeo onto Kilo. The airplane should have continued west on Kilo to the approach end of runway 32. Instead, the airplane accelerated west on taxiway Kilo. The departure roll was noticed by the local controller and an Anchorage departure radar controller. A radio call to the crew to abort the takeoff was not made by either controller.

The available taxiway distance from Romeo to the end of Kilo is about 6,800 feet. After departure, main landing gear tire impressions were found in a snow berm at the end of taxiway Kilo.

The airplane proceeded to Taipei and landed without incident. The NTSB has requested crew statements, and airplane flight data recorder information from the government of Taiwan.

At 0253, an Aviation Routine Weather Report (METAR) at Anchorage was reporting in part: Wind, 030 degrees (true) at 5 knots; visibility, 10 statute miles; clouds and sky condition, clear; temperature, 3 degrees F; dew point, -13 degrees F; altimeter, 29.91 inHg.
