when it comes to 4s stores, the first thing that comes to mind is car 4s stores. where should an airplane go if it needs repair and maintenance?
next to shanxi taiyuan wusu international airport, there is a base that provides full-cycle services for aircraft. what is the difference between an aircraft 4s store and an ordinary car 4s store? how do maintenance personnel "maintain" an aircraft? follow the reporter to take a look.
cgtn reporter shi yehan:a maintenance hangar next to wusu airport in taiyuan, shanxi province is equivalent to a "4s shop" for aircraft. an airbus wide-body passenger aircraft is undergoing maintenance work here. aircraft maintenance engineers are about to polish and repaint the aircraft. what is the difference between an aircraft 4s shop and an ordinary 4s shop? let's take a look.
the first difference is that the "store" is large. this hangar dedicated to wide-body aircraft painting and maintenance is 125 meters long, 96 meters wide and 34 meters high. in addition, the base has two hangars for narrow-body aircraft painting and maintenance, plus hangars, aprons, constant temperature and humidity aviation material warehouses, and ancillary facilities. the base covers an area of 1,089 acres, which is roughly equivalent to the size of 100 standard football fields.
in such a large hangar, the work done by maintenance engineers is more delicate than repairing a car. for example, this plane is undergoing repair work on the surface of the fuselage. usually, small wear and tear on the exterior of a car only affects the appearance, but even a small corrosion spot of 1 square centimeter on the surface of an aircraft will affect the safety of high-altitude flight. this dent is 11 mm long, 9 mm wide, and about 3.3 mm deep. it is the largest dent on this plane and the focus of this repair.
aircraft maintenance engineer han fei:the first step is to measure the size of the pit, its length, width and depth, and perform high-frequency eddy current testing on it, and compare it with the data in the manual provided by airbus. if it exceeds the standard or other damage is detected, we will directly cut it out and repair it.
after repairing the surface of the aircraft, the next step is polishing. unlike polishing the paint on a car, the paint layer on the surface of the aircraft is harder and the situation is more complicated. the maintenance engineer needs to judge the degree of polishing by touch.
aircraft maintenance engineer guo yuhao:this area is a relatively complex area, so we have to sand it manually to feel whether it is smooth or not, and to meet our operation requirements.
although there are many requirements for aircraft maintenance, like a car, as a means of transportation, it can also come to such a large "4s store" to enjoy one-stop service.
the first phase of this aviation technology remanufacturing base was put into production in 2021. the reason why it chose to settle in taiyuan, shanxi, was mainly due to the unique geographical location and favorable support policies. taiyuan has a dry climate without strong winds and heavy rains, which is suitable for aircraft parking and maintenance. in addition, it is located in the central plains and has convenient transportation, which is convenient for various types of aircraft to dock and the flow of aviation talents. after learning about the company's intention to settle down, the shanxi provincial government actively contacted the company and obtained construction land for the company in the comprehensive bonded area adjacent to wusu international airport, making it very convenient for aircraft to enter and exit.
wang lin, deputy director of the transportation department of the shanxi provincial development and reform commission:we will make overall plans for transport aviation and general aviation, low-altitude economy and airport economy, and solidly promote the construction of a national general aviation development demonstration province. we will build transport airports, general airports, aviation flight camps, etc. according to local conditions to accelerate the cultivation of chain leaders and chain companies, and promote the expansion and strengthening of the entire industry chain.
in recent years, shanxi has introduced a series of policies, including "several measures for shanxi province to accelerate the development of low-altitude economy and the construction of a demonstration province for general aviation", to encourage aviation manufacturing companies to take root here. at present, shanxi province has 24 aviation industry companies of various types, and is constantly striving towards the dream of flying into the blue sky.
