四月份V-22坠毁的原因查明，系飞行员操作失误

The 11 April, 2012, crash of a Bell-Boeing MV-22B Osprey tilt-rotor in Morocco belonging to the US Marine Corps's VMM-261 squadron was not due to a mechanical failure or and other safety defect.

Instead, the aircraft, which was participating in an exercise called African Lion alongside Moroccan forces, crashed due to pilot error. Two marines were killed in the accident, while the two USMC pilots flying the aircraft were severely injured.

Lt Gen Robert Schmidle Jr, the Marines' deputy commandant for aviation, says the aircraft took-off vertically with the wind coming from directly head-on relative to the aircraft. The aircraft climbed vertically to about two dozen feet into the air when the pilots decided to execute a pedal-turn to the right in order to avoid overflying some Marines on the ground.

As the pilots executed that turn, the wind was now coming from behind the aircraft. Moreover, the pilots had started to use a thumb-wheel on the MV-22's throttle/collective to rotate the aircraft's engine nacelles forward. That, Schmidle says, caused the Osprey's center of gravity to shift forward.

In the configuration, the pilot's control column did not have enough control authority to move the nose up. The aircraft subsequently flew into the ground, Schmidle says. An investigation found that the aircraft may not have crashed had the pilots kept the aircraft in helicopter mode.

Schmidle says that pilots were flying in a condition where the MV-22 Naval Air Training and Operating Procedures Standardization (NATOPS) manual advises caution-but there is no explicit prohibition on flying in that part of the envelop. But the manual could be clearer and it will be amended, he adds.

The MV-22 pilot community will also receive enhanced training and academics to better learn to recognize and avoid a similar situation if they should encounter the same conditions, the general says.

The MV-22 is a "solid, safe" aircraft, Schmidle emphasizes.

4月11日，2012年，贝尔 - 波音公司的MV-22B鱼鹰在摩洛哥属于美国海军陆战队的VMM-261中队的倾斜旋翼的崩溃并不是由于机械故障或其他安全缺陷。

相反，这是在参加演习的飞机，被称为非洲狮子旁边摩洛哥军队，坠毁因飞行员错误。两名海军陆战队员在事故中丧生，而飞机飞行两个美国海军陆战队飞行员严重受伤。

中将罗伯特Schmidle JR，海军陆战队航空副校长，说垂直风了小康飞机从头部直接相对飞机。飞机垂直攀升到空气中大约两打脚时，飞行员决定执行踏板转的权利，以避免飞越一些海军陆战队员在地面上。

作为飞行员执行，反过来，风正从飞机后面。此外，飞行员已经开始使用的MV-22的油门/集体向前旋转飞机的发动机舱上一个拇指轮。这，Schmidle说，造成的鱼鹰的重心前移。

在配置上，飞行员的控制列没有足够的控制权将鼻子。随后到地面飞行的飞机，Schmidle说。一项调查发现，这架飞机可能已坠毁，飞行员保持飞机在直升机模式。

schmidle说，飞行员在飞行条件的MV-22的海军航空兵训练与标准化作业流程（NATOPS）手册建议谨慎，但没有明确禁止在飞行的一部分，信封。他补充说，但手册可以更清晰，将修订。

MV-22的试点社区也将获得加强培训和学者，以更好地学会识别和避免类似的情况，如果他们遇到同样的条件，一般的说。

的MV-22是“牢固，安全”的飞机，Schmidle强调。The 11 April, 2012, crash of a Bell-Boeing MV-22B Osprey tilt-rotor in Morocco belonging to the US Marine Corps's VMM-261 squadron was not due to a mechanical failure or and other safety defect.
