South Korea (?) Helicopter crash caused by bad parts made in France! (Translated by google.com)
On July 17, 2018, MUH-1 Marine on Pohang fell during a test flight, causing five Marines to die and one seriously injured.
The civilian accident investigation committee that investigated the accident reported the interim results.
It was judged that the cause of the accident was a problem on the manufacturing process of parts called rotor mast.
Manufactured by Airbus helicopter subcontractor, Peru de Barrera, France.
The rotor mast receives the engine power and is the central axis that rotates the main rotor of the helicopter.
It is said that defects have occurred due to the water-cooling type of the heat treatment process to be performed in the air-cooling type.
O Peru de Baru decided that there was no abnormality after the inspection and delivered it.
The Airbus helicopter was further inspected and handed over to the Korean Aerospace Industries (KAI), a marine on the manufacturing company.
KAI mounted the rotor mast on the marine on without checking, and each time it flew, the force concentrated on the rotor mast, which had cracked during the manufacturing process, eventually broke.
Although the KAI's omission is an internationally recognized practice, the accident investigation committee is in a position to seek reasons for omitting the inspection.
There are four rotor masts produced at the same time, one mounted at the time of the accident, two at the pickpocket, and one at the Airbus helicopter.
The same cracks were found in the pick-up on stage 2, but the flight time was short and the accident did not occur.
The military official decided to carry out the survey of three marine onboards and 90 pickpockets.

Korea's reaction
I think it is necessary to develop a helicopter and it is heartbreaking in the development process.
I hope the accident will not happen again until the end of development.
Without verification, the responsibility of assembling must be clearly defined where it is
I am glad that the cause of the accident has been revealed. I would like to localize the engine and parts.
If Korea makes it, it can make well. Good luck to the five soldiers who were sacrificed.
Hey, where's the system? I can not get out of it, but if I have an accident, it is all wrong.
The conclusion is that non-destructive verification of imported parts is also required.
I do not think it is a mistake. If we were wrong, we could not get the rotor mast verification right.
I can not believe it. Director of the Korea Aerospace Research Institute Take responsibility and resign.
I need an army that does not fight with North Korea. I'm afraid of war. I'm scared.
President Roh Moo-hyun started the repair itself.
If you are a foreign country, why do you think it is such a psychological problem?
I do not want to use American parts. I want to make the minimum number of US parts. The motor is made in the USA. The body is made in Europe.
Everything is wrong with the government in the participatory government that created the monsters.
I am requesting compensation from a parts supplier.
This is the perfect opportunity for accumulating technology.
It is also France's level of china in Europe. France is not surprised because there are already a number of criminal charges against the world of weapons related to weapons.
What's the best in the world? Grinders ................

Editing impressions (Japanese editor's thoughts)
It is natural that it becomes a story about who will be responsible if an accident occurs.
This time, however, there was a problem with the parts of the French company, so we could not find any problems with the verification process.
Unfortunately, it is unfortunate that this is a good story if you make a machine product, and that it has caused human injury.
It is difficult to make a complete product in a considerable time. The car has a lot of accumulation, but even that is bad.
Certainly, importing finished products has few problems, but we can not even accumulate technology or export weapons to Korea.
It is called development of domestic helicopter, but most of the major parts were made in overseas, and some manufacturers were combined, and new parts were needed.
The main part of the contract was due to the fact that it had to produce overseas only for the contract.
The goal of localization rate was 70%, but it seems to be about 50%. Regardless of whether the main power is mostly overseas.
It may be said that the technology transfer of the core technology was a failure business because it was hardly received.
Rather than the Korean domestic weapon, the expression "Euro spec" will be more accurate.
It is pointed out that the development schedule was so strict that it could not secure sufficient quality.
Police, firefighting, and the Forest Service also deliver, but once the problem was a part of the issue will be a glimpse.
There is no way to know what the contract will be, but it is a good idea to intervene with the reparations and introduce improved parts.
In the future, because we plan to export, we can positively say that we were able to erase one of our worries.
It seems that the President of the Philippines, Teruta, was also interested, but was there any contact after that?
Thank you for watching.
I would appreciate your evaluation of the video if you do not mind.
It is fortunate that you can give me a favorable rating, bad value, and no specifications.
