A Study of Accident Prevention through Controlled Flight into Terrain Accident

Byeon, Soon Cheol

Abstract

The purpose of this study was to make landmark efforts to prevent the major causes of commercial-aviation fatalities on controlled flight into terrain (CFIT) in approach-and-landing accidents. Major analysis for controlled flight into terrain (CFIT) of Guam accident, Mokpo accident and Gimhae accident in commercial transport-aircraft accidents from 1993 through 2002 was made. CFIT occurs when an airworthy aircraft under the control of the flight crew is flown unintentionally into terrain, obstacles or water, usually with no prior awareness by the crew. This type of accident can occur during most phases of flight, but CFIT is more common during the approach-and-landing phase. Key prevention for CFIT accident was education and training for flying crew and to upgrade for equipment such as EGPWS, and the need for more research by professional organizations of airlines.
