发现直升机机尾传动轴上有一条加工刀痕，刀痕底部有一条裂纹。这个“疲劳源”不能长期承受正常载荷下的高循环，又逐渐想歪延伸成了大的裂痕，从而导致事故的发生。这一事故纯属制造质量问题。最终美国赔偿300万美元。

Answer 1

Found a helicopter tail drive shaft machining marks, there is a crack in the bottom marks. This "fatigue source" can not be under normal load for a long period of high cycle, but also gradually extended into a large crack, which led to the occurrence of accidents. The accident was a purely manufacturing quality problem. Eventually the United States $3 million compensation.

Answer 2

Found one on the helicopter tail drive shaft machining marks, marks has a crack on the bottom. This "fatigue crack source" cannot withstand high cycles under normal loads and gradually slanting extends into a large rift, which resulted in the accident. The accident is manufacturing quality problems. Final United States compensation of $ 3 million.

Answer 4

A score induced by trimming with a crackle at ——底部？底部是哪儿？一端吗？——an end of it was found on transmission shaft of the helicopter.Being unable to sustain persistent rotation at normal load, and resultingly expanded outwards, this has led to an accident, which is purely and totally a quality problem. As a result, America reimbursed 3,000,000 dollars.
