Boeing 767s need new landing gear after a grinder overheated a part

US aviation regulators are ordering all Boeing 767-200, -300, and -300F airplanes to replace a specific part of their main landing gear. This is because a maintenance error involving an overheating grinder caused heat damage to the outer cylinder of the landing gear, leading to a collapse.

This rule means airlines operating these specific Boeing 767 models must now inspect and replace a critical part of their landing gear. It highlights how even seemingly minor maintenance errors can lead to significant structural failures in aircraft. This type of directive ensures that a known safety risk is addressed across an entire fleet, preventing future incidents.
