RNF Iceland: fatigue factor in B 737-800 runway excursion at Keflavik
11 February 2009

The Icelandic Aircraft Accident Investigation Board (RNF) released their final investigation report regarding the serious incident involving a Boeing 737-800 at Keflavík, Iceland. The airplane operated a subcharter fight from Antalya, Turkey to Iceland. The flight crew made an unscheduled fuel stop in Edinburgh before continuing on the last leg to Keflavik. An approach was set up for runway 02 at Keflavik International Airport. The aircraft contacted the runway and then bounced up into the air again before full runway contact was made with the main landing gear tires followed by the nose landing gear tire.
The aircraft was not decelerated enough when nearing the runway end so the pilot flying attempted to turn the aircraft onto taxiway November at the end of the runway. The aircraft skidded off the taxiway and came to rest parallel to the taxiway with the nose landing gear and the right main landing gear off the paved surface.
It was amongst others concluded that the flight crew was likely fatigued and this had a degrading effect on their performance. The rest facilities and cockpit environments were less than optimal for sleep and decreased the likelihood that rest periods would help to reduce the risk of fatigue related errors.
On approach, the information on the runway and taxiway conditions the pilot flying received led him to expect that no extra precautions would be necessary during the landing. Upon landing there was absence or very little flare before touchdown which resulted in a hard bounced landing. The pilot flying did not use reverse thrust and braking to its maximum effectiveness and applied brake pressure late. (RNF)
