[Explanation] Recently, in the regular inspection hangar of Zhongchuan Airport in Lanzhou, Gansu, female engineers Chai Zongjing and Li Rongzheng sat cross-legged in the narrow "rear cargo hold" to perform line modification work.
On the entire control panel in front of them, the circuit "nerve lines" from various parts of the aircraft were densely covered, which was quite spectacular.
The lines vary in thickness, some are neatly combed, knotted and tied, and some are scattered on one side and twisted into several balls.
Chai Zongjing told reporters that the maintenance department is equivalent to the "inpatient department" of the aircraft. This thin line is like the nerve of the aircraft. Every time the maintenance and modification work is done, the tens of thousands of "fine nerves" are checked and classified and modified according to the picture. , And then bundle up, and connect the wiring accurately and accurately into each pore of the aircraft module.
Sometimes the lines will be staggered and entangled as soon as they are too many. It requires a lot of patience. Slowly combing one by one, just like unwrapping a ball of wool when you were a child.

These lines come from different parts of the aircraft, for example, some come from the cockpit, and some come from our electronic cabin.
Mainly this kind of thread is coiled together at the beginning, and then when you pull it, it will shrink to one piece, and it will be particularly easy to get tangled together, so the first step in making the thread should be Straighten our line, and then proceed with the wiring.
[Explanation] Girls are very scarce in the maintenance industry. In the Gansu branch, there are more than 150 people on the front line of maintenance, and only two of them are female maintenance personnel.
Since their job is to deal with airplanes every day, the question most asked by family and friends is "Can girls still repair airplanes?"

The advantage is that our minds will be more careful, and there must be certain disadvantages. The disadvantage is that our strength is insufficient, because some things, such as the batteries that we usually change planes, weigh up to 50 kg, and we have to move from the electronic cabin. Going down is indeed more strenuous.
[Explanation] Li Rong pointed to the sesame-sized letter while illuminating the plug-in hole with his headlight and told reporters that the letter next to the plug-in hole corresponds to each thread. As long as there is no corresponding one, the plane will Will "report failure".
After the modification is completed, many inspections will be carried out to ensure that the various systems of the aircraft that are handed over are foolproof.

The characters are very small, and sometimes it’s not very clear when printed on it, and some characters are especially easy to mix up, such as this 8, sometimes you can’t see the other side by accident, it’s a 3, so you have to turn it over Look at it carefully.
After everything is done, there will be a test run. Our test run is to simulate the state of our take-off. Then, for example, which system is faulty, it will jump out of this system failure, and then we will conduct troubleshooting.
[Explanation] Chai Zongjing said that this job of maintenance requires 100% seriousness and a sense of responsibility. Omissions in any step may cause serious consequences. Strictly implement "see one, do one, sign one", and sometimes work continuously for a day. , There is a thread in front of me.
After repairing an airplane, I will take a picture as a souvenir, full of sense of accomplishment.
