I spent enough time in the airline engineering maintenance and defence aerospace industries to gain a little knowledge, and that included spending a great deal of time working out what had failed/worn out prematurely and what we should do about it. For example like the rotten sprag clutch in the Airresearch starter on F28 APUs. We went through Sixty starters at about Ten grand each. The pilots ended up running the Port engine during stopovers in case they couldn't get a start.
Here is a question for you: Have you ever seen a tread separation beat the shyte out of a set of flaps and the wheel well contents like flap motors, gearboxes, hydraulics and spoiler and aileron controls? I have.
An "unraisable landing gear" is only a joke after you are back in the terminal and the gear has been pinned.
