Whether maintaining a legacy airframe with decades of “lessons learned” or a 5th generation aircraft with advanced automated aircraft health management and troubleshooting systems, The Dirty Dozen affects everyone. This list is by no means all-inclusive, but it includes some of the most frequent elements that influence people in the maintenance community to make mistakes, and understanding these hazards will enable maintenance personnel to avoid costly and dangerous errors.
To better equip maintainers to combat the risks they encounter daily, AETC Safety is leveraging what one safety expert termed “The Dirty Dozen.” This list identifies 12 of the most common human error factors that lead to aircraft maintenance mishaps. “We will always have to deal with operational and fiscal constraints leading to aircraft availability challenges resulting in the all too familiar feeling of ‘do more with less.’ Additionally, dealing with an emerging near-peer threat and finding innovative ways to employ airpower will create challenges in both mishap prevention and aircraft maintenance’s mission success.” “In my 16-year career as a tactical aircraft maintenance technician, I can tell you aircraft maintenance isn’t a job that is going to get any less demanding,” Gessler stressed. In the mishaps that occurred, a common theme developed: shortfalls in “back-to-basics maintenance,” or as some would say, “Maintenance 101.” Clinton Gessler, AETC Safety Directorate flight safety NCO. In the first half of 2023 alone, Air Education and Training Command experienced more than $23 million in aircraft damage costs associated with maintenance, according to Master Sgt. In the span of one shift, maintainers may encounter the risks of running a turbine engine at thousands of RPMs, falling from the potentially fatal height of wing, or losing a finger to a hydraulically actuated control surface.
