Dirty Dozen 

The activity I have chosen for a team to perform is an engine change. The scenario, which is a real life scenario, the aircraft is needed the next day to make a flight and you are installing the engine. There is so many human factors that play into this scenario but I just want to touch on one that I have experienced. Human factors is a situation of life that distracts physically or emotionally from the job at hand and can lead to you making a poor decision. The owner in this scenario who will be called MR. A has come down and said he doesn't care what it takes the aircraft must be ready by tomorrow, the pressure is on now. 

"Communication, written, verbal, and nonverbal other than written" (Johnson, 2016). I know that all human factors can intertwine with each other, yet I think communication is a large umbrella that en-captures most of the human factors issues. Pressure can come from how your boss communicated too the norms are communicated and can be accepted as tribal knowledge. 

Lack of communication plays an obvious vital role in aircraft maintenance. Communication can change due to slang and sometimes even education. For example while installing an engine you are about to hit something vital and possibly cause damage, You say stop, or maybe whoa, and even hold on. They all mean the same essentially yet the hoist operator may not stop. In my scenario I believe I said holdup and the operator didn't  and I now have an accessory gearbox jammed into the engine mount. 

What I learned from this experience is when working on a team insure you brief your teammates with a word that will halt the operation. If your not the one in charge then ask to clarify the proper commands giving during the maintenance operation you are performing.
