A Comparison of Malfunction-Related Accidents for General Aviation Aircraft Manufactured in 1970â•fi1984 and 2000â•fi2014

چکیده
The United States general aviation fleet is aging with aircraft manufactured 35–39 years ago representing the most prevalent group. Since older aircraft are more prone to airframe corrosion, fatigue, and brittle electrical wiring, the present study was undertaken to determine whether malfunction-related accidents for general aviation aircraft manufactured between 1970 and 1984 were elevated relative to airplanes produced more recently (2000–2014). The NTSB aviation accident database was used to identify piston-powered airplane accidents occurring over the 2005–2014 period. Aircraft manufacture year and fleet activity data were from the FAA. Statistical analyses employed contingency tables and Poisson

Causes and Trends in Maintenance-Related Accidents in FAA-Certified Single Engine Piston Aircraft
The accident rate for general aviation remains high. While most general aviation accident studies have been pilot-focused, there is little research on the involvement of aircraft maintenance errors. We undertook a study to answer this question. The Microsoft Access database was queried for accidents occurring between 1989 and 2013 involving single engine piston airplanes operating under 14CFR P...
متن کاملToxicological findings in fatally injured pilots of 979 amateur-built aircraft accidents.
BACKGROUND Specimens from aviation accident pilot fatalities are submitted to the Civil Aerospace Medical Institute (CAMI) for toxicological analyses. Trends of fatal amateur-built aircraft accidents and toxicological findings in the associated pilot fatalities have not been examined. METHODS Fatal amateur-built aircraft accidents that occurred during 1990-2009 were evaluated by retrieving in...
متن کاملThe Effects of Aircraft Certification Rules on General Aviation Accidents
The purpose of this study was to analyze the frequency of general aviation (GA) airplane accidents and accident rates on the basis of aircraft certification to determine whether or not differences in aircraft certification rules had an influence on accidents. In addition, the narrative cause descriptions contained within the accident reports were analyzed to determine whether there were differe...
متن کاملPilot-induced factors in fatal light aircraft accidents in the United Kingdom: 1969-1981.
The author reviews 52 personally investigated fatal light aircraft accidents involving 8 professional pilots and 44 private pilots. In 22 of the 52 accidents the presence of any pre-crash defect or malfunction of airframe, engine, or flying controls was definitely excluded. In the opinion of the author there was a "pilot-induced" factor in 35 (69.3%) of the 52 fatal accidents. The author discus...
