The research team at Embry-Riddle Aeronautical University (ERAU) conducted a series of analyses to find patterns and associations among general aviation (GA) accidents. This research is intended to provide the Federal Aviation Administration (FAA) with analyses of Fatal, Serious, and Minor/None GA accidents by examining the National Transportation Safety Board (NTSB) database for each region. The analyses shown in this report focuses mainly on examining GA accidents that occurred between 1982 and 2009 for each FAA region. According to the NTSB coding manual, there are more 320 codes that are used to identify the sequence of events leading to an aviation accident. However, a major portion of Fatal, Serious, and Minor/None GA accidents can be attributed to the ten most frequent initiating causes. The team provided comprehensive analyses of these initiating causes for all nine regions. This report provides exploratory statistics for accidents resulting in Fatal, Serious, and Minor/None injuries based on month, time of day, phase, and purpose of the flight. This report also explores the role of top the ten initiating causes and, in particular, attempts to find associations between GA accidents and experience of pilots. Furthermore, the report explores the role of aircraft complexity (based on engine horsepower) in Fatal, Serious, and Minor/None GA accidents. |
