I think this use of phrase "in fact" in the article is a bit Russian or otherwise Slavic. This usage shouldn't be illegal in English but is less common. Electricity needs both positive and negative connections made between power source to equipment to work, but some old vehicles only ran the positive(sometimes only the negative) wires, and used the entire vehicle body the negative wire. Idea is that the electrons are gonna find its own way, the body's thick as it gets as a conductor, it's fine if you knew what you're doing, it saves lotta weight. In this case, one of such connections to the body was secured with a screw, which could loosen from vibration, which `in fact` did. It instantly caused electricity to look for an alternative way, which was through propeller feathering switch and feathering relays, which caused the airplane to needlessly stop flying.
