This document summarizes data from three studies on approach and landing accidents between 1980-1997. It found that the most common types of accidents were controlled flight into terrain, loss of control, landing overruns, and unstabilized approaches. Common causal factors included procedural violations, lack of situational awareness, and continuing an unstabilized approach rather than initiating a go-around. The summary provides recommendations such as improving standard operating procedures, crew resource management, and flight operations management.
