Although the military plane successfully landed safely, the impact of the incident was very great, because the cause of the accident was not anything else. According to the investigation, it happened to be the engine of the aircraft.


    However, fortunately, the aircraft assembled in this accident was not produced by Tiangong technology, but was manufactured from a former Northern joining country and a later independent country. Most importantly, according to the data, it has been less than three years since the aircraft was manufactured.


    This made the superior very angry. After all, the engines purchased from this country were not one or two! But there are a whole batch of more than 200 sets.


    In addition to this batch of engines, the official also purchased several batches of engines from a motor engine manufacturing company in this country. It is obvious that now, due to the lack of funds and the loss of technology, the company''s engine manufacturing capacity is obviously declining, and the quality of the engines manufactured is also declining.


    ......


    At the scene of the accident, the forced landing fighter had been towed to a temporary apron at the edge of the runway. It was one of the latest main fighters in China. The engine was produced by a motor company in a country after the disintegration of a country in the north.


    At this time, the engine of the main fighter has been extinguished, and the experts of the base and the technicians of Tiangong technology are also analyzing the cause of the fire of the aircraft engine.


    Because the plane did not crash, plus the open fire had been extinguished, and the structure of the fire engine remained relatively intact, the search for the cause of the accident was very fast and the results were soon obtained.


    "Qiu Shi! After the inspection, the technicians of our company and the experts of your base unanimously determined that the quality of this engine did not meet the standard." after the inspection, Professor Zhang and the experts of the base reported to Qiu Shi.


    "What is really caused by the engine?" Qiu Shi replied. According to the video data during the fire before, the engine first vibrated violently, and then a lot of debris flew out. Finally, the engine exploded and then caught fire. Therefore, Qiu Shi has determined that there is a problem with the engine of the aircraft, and now the inspection finds that, Proved his prediction.


    "Qiu Shi! According to our inspection, the engine on the plane, where these faults occurred, was the bearing of the engine. Due to the serious wear of the bearing, the falling off of the bearing steel ball eventually triggered a series of chain reactions, which led to the fire and explosion of the engine.


    Fortunately, at this time, the plane has begun to land. Even if the engine power is lost, the success rate of the plane is relatively high.


    In other cases, if the engine has problems, the consequences will be serious.


    At the same time, according to our inspection, the bearing of another engine of the aircraft is also seriously worn. If this continues, similar faults will certainly occur in this engine in a short time.


    We seriously suspect that the bearing quality of this engine is not up to standard. We also suspect that in addition to the bearing quality of the engine bearing of this aircraft is not up to standard.


    There is a similar situation with engines in the same batch as this engine, which is just our guess. The specific situation can only be confirmed after checking other engines in the same batch, "said a military technician.


    After listening to the technician, Qiu also nodded and immediately asked someone to check the engine of the same batch of aircraft in the base.


    While we were discussing the engine of the aircraft, the roar of the engine came from a distance. Wang Bin, Professor Cha and others knew that the test flight of their phoenix-1 aircraft of Tiangong technology had been completed today. According to the task arrangement, after today''s test flight, the preliminary test flight of the aircraft had been basically completed. This aircraft, It will also be disassembled for inspection.


    If everything goes well, after the aircraft is reassembled, the aircraft will be handed over to Qiu division for test flight, and the subjects of test flight will no longer be these. At that time, the aircraft will be tested in various extreme weather and environment.


    For example, take-off, landing, transportation and other subjects in high altitude areas on the plateau, and test flights of bomber projects after installing some facilities, such as bomb dropping, loading large missiles and other test flights.


    For these subjects, Wang Bin and their Tiangong technology, in addition to sending the chief engineer and main technicians of the aircraft to participate, Wang Bin will not participate, and other technicians of Tiangong technology will not participate.


    On the same day, Qiu Shixian reported the accident and its causes to his superiors.


    At the same time, he also ordered their base to inspect all aircraft of the same type, especially those of the same batch.


    And the results came on the third day. After all, since the base has just been built, there are not many planes in the base, only 12. Among them, there are fewer planes of the same type as the accident plane, only three. As for the use of the same type of engine, there is only one other than the one that has had an accident.


    Mr. Qiu was shocked by the inspection results. As expected by Professor Zhang and others, there were more or less problems with the bearings of the same batch of engines. It was obvious that this was caused by the manufacturer''s problems.


    Subsequently, he reported the situation and also ordered to ground the aircraft using the same batch of engines first and wait for the new instructions from his superiors.


    However, what Wang Bin and Qiu Shi did not know was that after the situation on the shore of Qiu Shi was reported, the superior department attached great importance to it and issued an order to conduct a complete and thorough inspection of the main fighter engine.


    The result is also very surprising. There are more or less similar problems with the 100 engines in the same batch as the accident engine. As for the engines in other batches, the situation is better. As for the engines purchased from the northern Arctic country, the situation is very good without any problems.


    Wang Bin naturally didn''t know about this. However, when they finished manufacturing the second prototype of Tiangong technology, Qiu finally told him something. After all, Wang Bin''s identity is different from that before, so it doesn''t matter to tell Wang Bin about some things.


    What''s more, the engines of these aircraft with engine problems must be replaced. In addition to the manufacturers that previously provided the wholesale motivation and the same type of engines in Arctic countries, they can also choose the engine of Tiangong technology, while the superior departments and Qiu Shi prefer to use the engine of Tiangong technology.
