Columbus - Los Angeles

SKW5569, N683AV, had been cleared to runway 24L, at intersection 45, to position and hold. The local controller, because of her preoccupation with another airplane, forgot she had placed SKW5569 on the runway and subsequently cleared US1493, N388US, for landing. After the collision, the two airplanes slid off the runway into an unoccupied fire station. The tower operating procedures did not require flight progress strips to be processed through the local ground control position. Because this strip was not present, the local controller misidentified an airplane and issued a landing clearance. The technical appraisal program for air traffic controllers is not being fully utilized because of a lack of understanding by supervisors and the unavailability of appraisal histories.
