The security authority of the United States and Airlines shakes Hong Kong forbidden fl

Ming Pao News Agency

The Boeing Guimei 737 MAX 8 passenger plane, in just half a year, encountered air crash, and temporarily stopped flying and banned the same passenger planes in all parts of the world. Even the American solid allies Canada also joined the ban on flying last night., Boeing and Washington's inextricable relationship became the focus.Aviation is not afraid of 10,000 in case. In the case, many countries have decided to floor flight, not because it is 100 % clear about the problem of the passenger plane, but it cannot be 100 % sure it is really no problem.The decision by the Federal Aviation Administration (FAA) is to the global criterion. The professional judgment of FAAs is believed to be a professional judgment of FAA. This time, many countries have issued a flying order.At first, the Hong Kong Civil Aviation Department was still looking at the FAA horse. The ban on the ban decided to take a half -shot and need to review it.

Countries forbidden Boeing MAX 8 American Singing Anti -Trowth Sanda

Following the Indonesian Lion Aircraft at the end of last year, a Boeing Max 8 passenger plane crashed in Ethiopian Airlines a few days ago.Afterwards, China took the lead in or ordered that mainland airlines were flying to the same passenger plane. After that, Singapore, Germany, France, Australia, the European Union, Canada, etc. also decided.The next day the United States FAA issued a notice of continuous airworthiness.Flying passenger planes are a high cost for airlines, but nothing is more important than passengers.In the past two decades, the number of deaths in the global aviation accidents continued to decline. In just half a year, two serious air crash occurred, and nearly 350 people were killed in total, which was unusual.This time, since the 1970s, the US Macao DC 10 passenger plane has been crashed one after another in such a short time.

China initially issued a suspension order. Some US media believed that it was related to the Sino -US trade war. It was questioned that Beijing wanted to use Boeing orders as a negotiating chip. As other countries joined the flight and ban, it showed that the aviation community in various places did have doubts about MAX 8.It reflects that Beijing's approach is reasonable, but the United States is getting more and more isolated.Looking back at the two MAX 8 air crash, there are many similarities. Shortly after the off -the -handed aircraft, the accident was suspected to have control problems. Many aviation experts would have a spearhead and point to the phone's mobility enhancement system (MCAS).

In 2010, the European Airbus launched a new generation of A320 models. Boeing hurriedly launched 737 MAX to face it. In just a few years, nearly 5,000 were sold. There have been 340 delivery so far. China is one of the main buyers.The United States also lobby Beijing to buy more aircraft.Boeing advertises the MAX 8 engine to be more oily. However, since the new engine is larger than the old model, after the design adjustment of the passenger aircraft, the head of the machine is easy to raise. It is used to driving the old 737 pilot.The competitive advantage was introduced to the MCAS system adjustment, emphasizing that the existing 737 pilots can also drive directly.

The original meaning of MCAS is to prevent the machine from raising to a dangerous angle. However, once the induction system fails to send an error signal, the head of the machine may be unexpectedly lowering and dive quickly down.Since the MCAS system preset is an overhead pilot, it means that even if the captain attempts to manually control it, it may not be able to stop the dive of the passenger plane. The investigation shows that the lion air is difficult to be related.There is an operation manual and did not mention how to turn off this automatic system.In 2013, the Boeing 787 Dream Passenger Aircraft suspected that due to the overheating of lithium batteries, FAA also ordered the grounding for 6 weeks. The then Minister of Transport Ladhide said that Boeing was also decided to not fly at that time.The Max 8 should also be grounded.Now that FAA, on the one hand, Boeing must improve the system before the end of next month, but insist on having no reason to fly, the outside world will inevitably suspect that the FAA is diluted.

The Hong Kong Civil Aviation Department's follow -up of the car is not enough to criticize independently

The proportion of Boeing Taoism means more than 10 %, and the full grounding must be fell to the US stocks. President Trump has always been close to the stock market trend. Of course, he does not want to see this situation.In addition to being one of the largest employers in the United States, Boeing is also a major arms supplier. It is closely related to Washington. The current actions of the Ministry of Defense Changsha Nahan are also former Boeing seniors.Boeing's influence is unusual. On the other hand, as the regulator of the US aviation industry, FAA has become more and more difficult in recent years. The White House has reduced FAA budget appropriations for two consecutive years.All these have made the outside world pay attention to FAA's supervision capabilities.

In the past few decades, the US aviation industry has called the world. All international airlines must comply with the FAA standards in the United States. The international community also believes that FAA's professional judgment.In the past, FAA would assign foreign experts to be responsible for aircraft safety standard certification. However, due to the tight finances, FAA changed the relevant system in 2005, allowing Boeing and other aircraft manufacturers to use their own employees as certification experts to certify themselves.Jim Hall, former chairman of the National Transport Safety Commission, pointed out that a major problem is that FAA is a regulator and has a close relationship with Boeing. As a result, the manufacturer actually serves as a supervisor.This time, Max 8 had an incident, and the outside world inevitably hoped that why FAA did not notice MCAS's hidden dangers that year, and still issued a security certification to MAX 8.

The leadership status is not to say it by themselves, but by others Xu Yu and accumulating for many years. When others find that the leaders are selfishly spending the interests of everyone, they will not follow.If other countries have questioned that Washington only escorts the interests of the US aviation industry, it is not for passenger safety first, and FAA may lose its global aviation security leadership in the long run.This time, various countries voted to Washington and FAA. They were a police sign for Trump, which emphasized the preferred interests of the United States, and the Hong Kong Civil Aviation Department should also reflect on whether this time was not independent enough.Hong Kong's slow half -shooting order in Hong Kong, such as the Mainland, Indonesia, Singapore, is not the biggest problem. The real problem lies in the mentality.After many countries decided to ban flying, the Civil Aviation Department first still said that the Max 8 was promoted in Hong Kong on the grounds of the United States that it was suitable for flying, and then hurriedly turned. This performance was certainly ideal.
