Welcome back to the our channel for a discussion about the process of producing, checking and retraining aircraft tires and how maintenance crews add to the overall passenger experience. Does confirm it can cost up to $6000 for a single commercial plane tyre and even less depending on which plane tyre. Seeing planes have between 6 to 18 tyres, it really adds up really fast. As an exercise in exacting design and manufacture, the landing gear mechanisms for large aircraft are things of beauty. Totally under appreciated by most of the flying public. That 777 main gear assembly seen at 07:37 is, in my view, a work of technological art. If you’ve ever landed in an airliner, thank the people who designed, and fabricated these marvels. It’s unreal the amount of force these tires have to endure during their short life. 300,000 flight hours on the 787 engine cannot be correct. Aircraft are typically retired at less than 100,000 hours. My guess is 40,000-60,000 hours top on an engine. We changed our engines every 20,000 hours or less.
