HS code harmonization in NAFTA region

The HS code harmonization in NAFTA regionengine put white sugar (the engine soaked white sugar, the captain made an emergency landing!) A horrying aviation accident has recently attracted wide attention around the world. It is reported that a passenger plane carrying hundreds of passengers suddenly had an engine failure during the flight, and the captain had to make an emergency landing. However, what attracts attention is that the cause of the air crash is actually due to "sugar"! It is reported that the passenger plane belonged to a large international airline, which was operating flights from Beijing to New York at that time.Everything seemed very normal until the plane had been flying for nearly three hours, when the captain suddenly received an emergency warning that the engine had failed. At this time, the captain immediately organized the crew to deal with it and asked the aviation control center to arrange a landing. However, after some investigation, people knew that the root cause of the engine failure was that an unknown mechanic on the passenger plane actually added white sugar as lubricant when maintaining the engine. Because white sugar contains a large amount of sugar and moisture, the parts in the engine have been seriously damaged, which eventually leads to failure. The airline and the mechanic themselves were also very surprised by such a thing. In this regard, the relevant departments conducted an in-depth investigation and educated all staff about the mechanical knowledge and understanding of the aircraft in response to the incident.Throughout the incident, although there were no casualties, the aviation accident profoundly told us that safety is not a trivial matter, and uncertain factors should not be added to the complex mechanical system indiscriminately. In fact, for aircraft, the design of its shape, power, control and load is rigorous, and even a small change can lead to serious consequences. In order for the complex flight machinery system to operate normally, professional and technical personnel from all sides need to carry out rigorous inspection and maintenance. At present, with the improvement of domestic civil aviation, the flight safety problems of civil aircraft are gradually emerging. At this time, we need more technology, more innovation and stricter systems and standards to ensure the safety of aviation. Only by achieving strict quality control and technical supervision can we improve the controllability of flight safety and ensure the safe travel of the majority of passengers.Of course, in daily air travel, we also need to maintain awe and a high degree of vigilance. Even some small aspects, such as the choice of food and drink, need to be examined very carefully to avoid dangerous factors for normal flights. In a word, in the future, we need to pay more attention to the safety of civil aviation, and understand and be more aware of the harmfulness of the factors before the flight accident occurs, so as to respond accordingly. At the same time, the maintenance and overhaul of the mechanical system requires some conscientious and professional mechanics to maintain, so as to ensure the more stable and long-term development of the civil aviation passenger transportation industry.
