Previously, you completed the FAA PDF reading activity about the PEAR Model; A Model to Explain Human Factors in Aviation Maintenance by Dr. William B. Johnson. Now, read the NTSB Report ATL02FA175 (Links to an external site.)Links to an external site. and The PEAR Model: A Case Study fact list below about an actual accident which took place in Milton, Florida.

Apply what you learned from your research by creating a discussion post. In this discussion post, select an element of the PEAR Model that can assist with understanding the human failures in this real world case study. Explain possible human factors that may have led to the corroded cable being overlooked during the annual inspection. Do you believe human factors explain why there was there an unauthorized, undocumented part installed in this aircraft. Could the PEAR Model have prevented the cable failure, engine power loss, and the resulting death of the pilot? What other questions could the Pear Model help us analyze and prevent something like this from occurring again?

Your post must focus on explaining the maintenance and safety issues, and describe why and what documentation is required. You must use a minimum of 150 words and use proper grammar and spelling.

Comment on two posts of other students. Your reply must contain at least 50 words and use proper grammar and spelling.

The Discussion Rubric will be used to evaluate your posts in each module forum throughout the course. For more information, please review the Discussion Guidelines in the Course Specific Information area, as needed.

The PEAR Model: A Case Study

At 1830 hours, September 23, 2002, a Piper PA-28-140, registered as N8828N crashed into an old oak tree in Milton, Florida narrowly missing a home with people inside.

A student pilot, an active duty Marine was killed.

The Annual inspection was completed September 19 2002.

Although the fuel pump was found operational, it was not approved for aviation purposes. The accident report stated: “During the examination of the airframe fuel system, an unapproved part was found. An automotive electric fuel pump was found installed in the system. The electric fuel pump was labeled "automotive electric fuel pump" and "not recommended for use in aircraft applications.“ The log book did not show this fuel pump as having been replaced.

The final report showed that a mixture control cable was corroded due to severe wear. This cable sheared causing the engine to have a lack of power.

According to the FAA Report, "Examination of the engine cockpit controls found them in the cutoff position. The fuel selector valve handle was found at or near the off position. The airframe to engine controls were found in a deteriorated condition. The mixture control was found separated at or near the mounting bracket, adjacent to the carburetor. The inner cable strands appeared worn; the outer cable sleeve appeared corroded. The mixture control cable assembly was removed and sent to the NTSB Material Laboratory in Washington, DC for further examination. The airframe to engine carburetor heat control cable end was found separated from the control arm at the air box. During the examination of the airframe fuel system, an unapproved part was found. An automotive electric fuel pump was found installed in the system. The electric fuel pump was labeled "automotive electric fuel pump" and "not recommended for use in aircraft applications." The electric pump was removed and field tested by applying the aircraft's battery and fuel to the inlet. The pump pumped fuel out of the outlet. The pump was operational. The FAA took possession of the fuel pump. A review of the maintenance logs found no record of the electric fuel pump's replacement."

In Module 1, you submitted an abstract for your research paper on human factors in aviation maintenance. In this activity, you will prepare a Pecha Kucha presentation based on your topic proposal. Provide 10 slides, with a 20 second presentation for each slide either in audio or caption format. Be sure to properly cite and reference sources for all content.

Share your Pecha Kucha presentation in this forum. You may submit it in whatever format works best, whether it be a file upload, embedded HTML presentation, link to an external presentation, etc. Once you have shared your presentation, please view your peers' presentations. Replies are optional, but encouraged.

In the previous activity, you learned about identifying and documenting problems with an aging aircraft fleet. Now, use this discussion forum to share what you have learned. Consider any examples in the reading material where identification and documentation of aging aircraft inspections prevented an accident/incident/catastrophe. What differences in maintenance and recordkeeping philosophy (staying with aging aircraft) are there between general, commercial, and military aviation? What are the risks and benefits? What about maintenance costs, fuel efficiency, and emissions? Be sure to think beyond the questions posed here and consider all aspects of the aging aircraft in domestic and international aviation.

Previously, you were presented with two video examples of aircraft wiring failures and informative articles on aircraft wiring inspections. After reviewing the articles and videos pertaining to TWA Flight 800 and Swissair Flight 111, analyze the information to determine how AMTs can ensure safer aircraft wiring though proper inspections.
