“I’m learning how to repair the opening mechanism of an aircraft door. Two weeks of training are set aside for this. The door I’m working on is in the training workshop. One of my instructors has installed a faulty component and I have to figure out what it is and repair it. A rattling noise indicates that there’s something wrong with the door’s gearing mechanism. Without it and its six cogwheels, the heavy door would be much more difficult to move. Wear and tear on the cogs causes the wheels to start rattling. That’s why I remove the gearing mechanism and inspect it for signs of wear using a flashlight, a mirror and a measuring instrument called a feeler gauge. Once I find the faulty cogwheel, I replace it with a new one. Then comes the moment of truth: Does the mechanism work perfectly again or have I made a mistake and installed the wrong component? If so, I have to begin the procedure all over again and spend another six hours searching for what’s wrong.”
