Unfallbericht:
The Boeing 747 operated on a cargo flight from Dubai to Düsseldorf on behalf of Emirates. The en route part of the flight was uneventful.
The flight crew established radio contact with Düsseldorf Radar at 05:43. The crew were told that runway 23L was in use.
Two minutes later the radar controller contacted flight 8995: "I just talked to the tower and ah for the time being braking action on all parts of the runway is supposed to be good. They are measuring again right now because it started to snow again and I'll keep you advised." The flight was then cleared to descend to FL80. The flight crew decided to set the autobrakes for landing on Medium, to account for the snow.
At 05:50 the radar controller again contacted the flight about the current weather circumstances: "...latest update on the weather situation ahm the friction tester has reported braking action to be good for the moment however as its continuing to snow they are ah afraid that it might worsen, so they are going to do another friction test right before you land."
In the following minutes the flight was given descent instructions and vectors for an approach to runway 23L.
At 05:54 the controller radioed: "weather update we now have a surface wind of three four zero degrees eleven knots, that's slight tail wind component by two knots. Visibility is down to one thousand five hundred meters, still in snow showers and ah cloud base is now five hundred feet only."
The flight was subsequently cleared for the approach.
At 05:57 the radar controller instructed the crew to contact Düsseldorf Tower. The Tower controller stated: "Good morning,... we are just waiting for the braking action values from the friction tester stand by a second. The surface wind is actually three three zero degrees one two knots."
Two minutes later the controller radioed: "... the braking action was measured to be medium at all parts. And ah the visibility dropped right now due to the heavy snow showers at the field ah. The RVR value at the touch down zone is presently nine hundred meters, at the mid-point one thousand one hundred meters and ah stop end one thousand one hundred meters." At that moment the flight was 3,5 nautical miles out. The flight was subsequently cleared to land.
The airplane touched down about 1700 ft (518 m) past the runway threshold. Ground spoilers and thrust reversers deployed and the autobrakes activated. Still the airplane did not decelerate as expected and the pilot applied manual braking. The airplane failed to stop and overran the runway end. It collided with ILS aerials, which caused a fire in engines no. 2 and no. 3.

The aircraft was withdrawn from use at Düsseldorf until being scrapped there in April 2006.

Probable Cause:

Ursachen:
Der Flugunfall ist darauf zurückzuführen, dass die an die Besatzung übermittelten Bremswerte nicht den Bedingungen entsprachen, die sich infolge des starken Schneefalls seit der letzten Messung auf der Piste ergeben hatten.
Zu dem Flugunfall haben beigetragen:
- die hohe Dynamik der Wetteränderung
- das Fehlen einer unter allen Wetterbedingungen zuverlässigen Messmethode für die Ermittlung von Bremskoeffizienten
