| Executive Summary: | On February 1, 1991, at 1807 Pacific standard time, USAir flight 1493, N388US, a Boeing 737-300, collided with Skywest flight 5569, N683AV, a Fairchild Metroliner (SA-227-AC) , while the USAir airplane was landing on runway 24 left at Los Angeles International Airport, Los Angeles, California. The Skywest Metroliner was positioned on the same runway, at intersection 45, awaiting clearance for takeoff. As a result of the collision, both airplanes were destroyed. Al l 10 passengers and 2 crewmembers aboard the Metroliner and 20 passengers and 2 crewmembers aboard the USAir airplane were fatally injured. The National Transportation Safety Board determines that the probable cause of the accident was the failure of the Los Angeles Air Traffic Facility Management to implement procedures that provided redundancy comparable to the requirements contained in the National Operational Position Standards and the failure of the FAA Air Traffic Service to provide adequate policy direction and oversight to its air traffic control facility managers. These failures created an environment i n the Los Angeles Air Traffic Control tower that ultimately led to the failure of the local controller 2 (LC2) to maintain an awareness of the traffic situation, culminating in the inappropriate clearances and subsequent collision of the USAir and Skywest aircraft. Contributing to the cause of the accident was the failure of the FAA t o provide effective quality assurance of the ATC system. The safety issues raised in this report include: o Air traffic management and equipment at Los Angeles International Airport. o Aircraft exterior lighting and conspicuity. o Pi lot situational awareness during takeoff and landing and operations on airport surfaces. o Air traffic controller workload, performance, and supervision. o Air transport accident survivability, evacuation standards and procedures, interior furnishing flammability standards, and survival devices. Recommendations concerning these issues were addressed to the Federal Aviation Administration. |
