Human Factors Ignored on the Maintenance Floor - Episode 133

An accident involving a Hughes 269C helicopter demonstrates the lack of depth in accidents attributed to maintenance errors. Once again, there is no analysis on the human factors involved among maintenance personnel.
The NTSB probable cause for this air crash points to an improperly installed mounting bracket on the engine. The supporting details and aviation insights are lacking.
“My frustration is that they go no further than to say this is a maintenance issue,” John Goglia says. “No human factors are explored although that is as important in maintenance as it is in the cockpit.”
John, Greg and Todd find many questions unanswered. They discuss the value in going deeper than “maintenance screwed up.”
They explore the many questions not investigated that could lead to information that people can learn from. They talk about why even the most benign accidents can result in aviation safety benefits. This accident report is among many that are a disservice to the aviation community because it is superficial.
Also in this episode, Greg retracts a Episode 131 statement that 50% of NTSB probably causes are wrong. He does not have sufficient documentation to support the statement. However, he stands by his statement that he is confident that at least half of NTSB reports are incomplete.

Greg and John you guys were who I looked up to in my youth , was a pleasure meeting you both as an Embry-Riddle student 20+ years ago - Now that I have grey hair , as someone outside of accident investigation,I really feel that the board is often "reading tealeaves" in determining probable cause

Like your looking into the background of accidents and deep-roorted causes... Have a great friend who is a Top bicycle mechanic, and awarded for his work and mechanical work on bicycles...He started to work on his Helicopter rating and sometimes pointed OUT that there was a mechanical deficiency and would not fly. Sometimes the flight school did not like his overview of looking at their aircraft... Seem sad that good mechanics are worth their weight in Gold to prevent mechanical breakdowns... Thank you for pointing out the two most important items of who/or how many did the work on it, as well as how long ( did it take ) and how many worked on it and how many shifts.
