Aircraft Accident/Incident Report
Portland, Oregon 97218

NTSB Narrative Summary Released at Completion of Accident
Shortly after landing, aircraft (acft) began veering slightly left, & 1st officer (F/O, flying pilot) applied rudder for control, then captain (capt) assumed control of acft (above 60 kts). Capt realigned acft to runway centerline & called for condition levers (CL) to minimum (min) at about 60 to 70 kts. At this time, acft began to veer left again. Capt was unable to maintain directional control as acft veered sharply left. Right wing tip & right propeller contacted runway. Acft then collided with a runway sign before stopping partially off runway. Horizon Air procedures indicated CL were to be positioned to maximum (max) when main landing gear touched down. After landing, CL were to be positioned to min at the capt's discretion. With CL in max position, the flightcrew had up to 10 deg of nose-wheel steering through the rudder pedals. With CL in min range, 60 deg of nose-wheel steering authority was available through the tiller. Dornier 328-100 Airplane Operating Manual stated under Standard Landing Procedures that at a 'safe speed,' the CL should be retarded to the min position. Shortly after the accident, Horizon Air changed its landing procedures to state acft must be at taxi speed (below 30 kts) before capt commands CL to min. No mechanical failure/malfunction found.
