Had a new guy one time that was working a discrepancy list. One was "Brakes are excessively noisy". So, this guy attaches a tow bar to the plane, and moves the plane back and forth, listening for the "noise". Sure nuff, the brakes are squeaky, making that chirp-chirp noise brake pads do, when they are worn down to the rivets........He greased the brake disc :shock: Well, they didn't squeak anymore. :lol2:
Then there was the guy who was repairing a leaky oil pan (aluminum pan). His plan was to weld the cracked pan without removing the pan from engine, or engine from aircraft. So, he was aware that he would need to drain the oil, and necessarily clean the area good enough to weld. His method (He did this on his lunch break, while everyone including myself was away), involved filling the crankcase/oil pan with solvent, then draining. He repeated this several times. He then removed the oil dipstick from the oil filler neck, and poked a solvent sprayer down into the case (atomized solvent). He removed sprayer, and sat the dipstick (not him; the oil dipstick), back on the neck. His problems began when he realized that solvent was weeping out the crack he intended to weld, and opted for a propane torch to "dry out the crack". He was still shaking when I got there, the dipstick punched a hole in the roof of the hangar, the cracked oil pan was now a bulging oil pan, and we would later learn that numerous engine gaskets leaked. Who knew?

A guy goes to the tool room for a soldering iron. There are 2 to choose from, both 110v electric. They are identical. But he knows one of them doesn't work, and is heard mumbling something about how he "always picks out the bad one" as he walks from the tool room. Well, he did pick the bad one, and instead of just tagging it "INOP", or even throwing it in the trash, he desides on a permanent solution; he cut the cord with wire cutters, while it was still plugged in :shock: . We called an ambulance on that one. I don't know what it is about 110v, some people just can't handle it.
I blame myself
