Japan Airlines Flight 123, Boeing 747-SR100, JA8119 China Airlines Flight CI611, Boeing Model 747, B-18255 American Airlines Flight 191, McDonnell Douglas DC-10-10, N110AA This case study explores aircraft maintenance, inspection, repair, or alteration flaws, often involving errors or faulty assumptions during the maintenance process. Feel free to explore each of the accident descriptions to help you decide if there is a particular accident you wish to study over the other two. As you study and research the accident you chose, be sensitive to discover what the flaws, errors and faulty assumptions were. You will analyze this case study in terms of mechanical and structural factors and provide a technical report which analyzes this accident case study (usually five or more pages including a title page and reference page). This written assignment will be formatted as a research paper, using Times-New-Roman, 12-point font and double-spacing between lines of text. All sources should be cited using the American Psychological Association (APA) current edition style and format. Papers must be grammatically sound and free of spelling errors. 

The case study analysis must include the following sections, sequentially: Title or Cover Page - Include title, activity number, course number, and your name at a minimum. Introduction or executive summary - include a brief paragraph to introduce your reader to your approach to this analysis and what to expect. Primary Causal Factor(s) of the Accident - Include one to two paragraphs identifying the probable cause(s) of the accident. Usually, it is hard to narrow an accident event down to a single cause, especially if two related or intertwined systems or system components are involved simultaneously, referred to as 'coupling' in the context of safety analysis. This content must be evidence-based and factual in nature. Contributing Factors to the Accident - Include two to four paragraphs identifying what the contributing factors were causal to the accident. These factors contributed to the accident, even though they weren't primary. These factors could be links in the 'accident chain' of events leading up to the mishap. These factors may reduce or exacerbate the accident conditions and resulting severity. A thorough analysis in this section should aid you in formulating potential risk mitigation or reduction strategies in a subsequent section. This content must be evidence-based and factual in nature. Structural and Mechanical Factors Related to the Accident - Include two to four paragraphs identifying the structural and mechanical factors involved in this accident. This portion should entail the bulk of your analysis. Use this section to detail any strengths and weaknesses of the applicable aviation system(s), whether aircraft design, construction, maintenance, component reliability, etc. This content must be evidence-based and factual in nature. Relevant Human Factors and/or Organizational Factors Related to the Accident - Include two to four paragraphs identifying what the relevant human/organizational factors were involved in this accident. Be sure to include how these deficiencies led to or exacerbated the situation. This content must be evidence-based and factual in nature. Outcomes of the Accident - Include two to four paragraphs stating what happened subsequent to the accident (this may be months or years later). Although a bulleted list of outcome items may be provided, there should be sufficient explanations to describe any disparities between the investigation board's proposed solutions (i.e., recommendations) versus 'real-world' eventual actions by the various governmental and industry groups. Examples may include possible airworthiness directives (ADs) issued, new regulations or rules adopted or amended, redesign standards, etc. Consider which recommendations were suggested by the investigation board. Were these recommendations followed or complied with? What recommendations were left unheeded? If so, why? This content must be evidence-based and factual in nature. Risk Mitigation or Reduction Strategies - Include two to four paragraphs explaining, from your analysis, any risk mitigation or reduction strategies or methods that you believe may have either prevented this accident or lessened its severity. This is your opportunity to demonstrate and integrate your knowledge learned up to this point of the course and apply learned facets in analyzing this accident. This is where you can interject your opinions, suggestions, any differences you may have regarding investigation board results, and any differences toward eventual outcomes related to this accident.
