E199 - The Dirty Dozen

In this episode of Behind the Prop, hosts Bobby Doss and Wally Mulhearn dive into the Dirty Dozen, a set of twelve human factor traps that can affect pilots and mechanics alike. Originally released by the FAA around 2011 or 2012 as a poster for mechanics, these traps apply equally to pilots and can lead to serious situations if not recognized. The discussion covers everyday traps like complacency and distraction that bite on routine flights, as well as decision-making and awareness issues. Bobby and Wally share personal anecdotes, including stories about fuel checks during checkrides, the dangers of expectation bias, and real-world incidents like the Eastern Airlines Flight 401 crash caused by a distraction over a light bulb. They emphasize how these factors, including fatigue, pressure, lack of communication, and normalization of deviation, can cascade into problems for even experienced aviators. To combat these traps, the hosts offer practical defenses such as setting personal minimums, chair flying, using checklists effectively, and maintaining situational awareness. They stress the importance of being prepared, honest with oneself, and continuously learning to avoid the Swiss cheese model of accidents. Listeners are encouraged to review the Dirty Dozen poster linked in the show notes.
