A UPS United Parcel Service McDonnell Douglas MD-11, registration N277UP performing freight flight 5X-61 from Seoul (South Korea) to Anchorage,AK (USA) with 4 crew, was accelerating for takeoff from Seoul Incheon Airport's runway 33L at about 22:40L (13:40Z) when the crew needed to reject takeoff at high speed. The aircraft overran the end of the runway, broke through the approach lights and the localizer antenna and came to stop about 350 meters past the end of the runway on soft ground, the nose gear collapsed. The crew evacuated the aircraft, one crew member received minor injuries. The aircraft received substantial damage.

On Jun 8th 2016 the FAA reported on crew remember received minor injuries when the aircraft went off the runway during a rejected takeoff and came to stop with the gear collapsed.

In June 2019 South Korea's ARAIB released their final report in Korean only (Editorial Note: (Editorial note: to serve the purpose of global prevention of the repeat of causes leading to an occurrence an additional timely release of all occurrence reports in the only world spanning aviation language English would be necessary, a Korean only release does not achieve this purpose as set by ICAO annex 13 and just forces many aviators to waste much more time and effort each in trying to understand the circumstances leading to the occurrence. Aviators operating internationally are required to read/speak English besides their local language, investigators need to be able to read/write/speak English to communicate with their counterparts all around the globe). The report concludes the probable causes of the accident were:

The crew rejected takeoff at high speed at/slightly above V1 due to tyre and drag brace defects at the body gear, the aircraft overran the runway.

Contributing factors were:

- limited time and information available to the captain to assess the situation

- difficulty for the captain to determine the aircraft's in flight performance and the dynamic instability of the body gear drag brace following the defect

- decline in braking performance due to the rupture of a hydraulic pipe

The aircraft was accelerating on runway 33L when at about V1 a body gear tyre burst causing damage to the body gear, at about the same time the pilot monitoring called V1 (which was not acknowledged by the pilot flying). As result the acceleration of the aircraft sharply reduced prompting the captain, pilot flying, to reject takeoff due to structural damage. About 3.3 seconds after accelerating through V1 the engines begin to spool down, the aircraft had reached a maximum of 182 KIAS and was 4635 feet before the runway end at that time (the ARAIB annotated that at the nominal V1 of 169 KIAS the distance to stop needed was computed at 5385 feet). The body gear indication changed to unlocked and unsafe. The right brakes 1R hydraulic line ruptures causing the loss of the associated hydraulic system and brakes. The aircraft overran the end of the runway and came to a stop 485 meters/1590 feet past the end of the runway. The nose gear collapsed, one member of the flight crew received minor injuries.

Should an English version of this report ever become available, we'll provide further summary of the factual and analysis portion of the report.
