Fault or Functional Hazard Analysis (FHA) takes Failure Mode and Effects Analysis (FMEA) by determining the effect of a component failure on a system, subsystem, or personnel. This week’s discussion is based upon the video Seconds From Disaster United Airlines Flight 232 (Links to an external site.) (YouTube/45:46) On July 19, 1989, the tail-mounted No. 2 engine of United Airlines Flight 232 exploded, causing serious damage to the aircraft's hydraulic systems and leaving the flight controls unusable. As you watch the video identify hazards relating to the failed aircraft system. In your initial post use the risk assessment format in Chapter 11 pgs. 141-142 of the textbook to explain: Hazard Risk Risk Assessment Control Approach In responses to classmates provide a recommendation for mitigating one hazard identified based on system safety precedence provided in Chapter 2 pgs. 20-21 of the textbook. Explain why the mitigation method was chosen. Please meet the following criteria for discussion posts: 1. Post should be a minimum of 200-300 words grammatically sound. 2. Initial post by the fourth day of the Module. 3. Your main response should be an in-depth analysis or interpretation. 4. Please reply and respond with a substantive post to at least two of your classmates by the last day of this module. 5. To ensure that all students receive feedback, reply first to any students who have not yet received replies from other students. Hazard Risk: Improper engine inspection Risk Assessment: The United Airlines technicians had done a routine inspection of the fan disk just sixteen months before the crash. The fatigue crack was on the fan disk surface at the time of the inspection and was also of a detectable size. Even though the report states that the inspection procedures at United Airlines complied with regulations and were up to industry standards, the fact remains that the poor engine inspection did not discover a fatigue crack on the fan disk surface that was sizable.
