7 Jan 2016 - 737-400, YR-BAS (27007/2367), FF 10/09/1992, operated by Blue Air overran the runway paved area at Cluj on 7 Jan 2016 by 20m after a long landing in snow.
The weather conditions were poor with snow and fog. The runway was wet with snow deposits and braking action medium.
LRCL 070630Z 08005KT 0700 R25/0900U SN FG SCT003 OVC008 00/00 Q0995 R07/590393
The Captain initiated the flare at 45ft which led to a prolonged float. The aircraft touched down about 700m past the runway threshold. Cluj Runway 25 LDA is 2040m. The captain deployed thrust reversers, and Autobrake 3 engaged normally. In the last part of the rollout the Captain applied manual brakes thereby disconnecting the autobrake, but was not able to slow the aircraft in time to avoid an overrun. The aircraft veered to the right and passed the runway end at 10 knots groundspeed.
The cause of the serious incident was an extended flare/float, that resulted in a touchdown 700 meters past the runway threshold.
Contributing factors were:
- Winds from 100 degrees magnetic at 5-10 knots
- Landing speed was 140 KIAS, 11 knots faster than computed according to AOM (129 KIAS)
- The flare was initiated at 45 feet AGL rather than 25 feet AGL as recommended by Boeing
- The runway was covered with wet snow up to 1cm, which covered 51-100% of the runway surface
- Insufficient visual cues
- Inconsistent brakes pressure on brake pedal operation
