[0002] Aircraft engine lifting point parts are divided into front lifting points and rear lifting points, which are composed of multiple lifting point single pieces. They are installed at the front and rear ends of aircraft engines and are used to connect aircraft engines to aircraft when they are hoisted on aircraft. At the same time, they transmit the thrust generated by aircraft engines to aircraft when the aircraft is flying. They are key components of aircraft engines. After long-term and multiple cycles of aircraft engines, due to the vibration of the engine and long-term stress, the engine lifting point parts need to be disassembled, inspected, repaired, worn and non-compliant parts replaced, and assembled to ensure that the engine lifting point parts can work normally and safely.
