An aircraft was killed in the aircraft when the fan blade broke and caused part of the engine cover to hit the jet side. This broke one of the windows and the cabin quickly lowered. The crew managed to land the plane, but the woman sitting by that window was killed.
The National Transportation Safety Board investigating the accident recommended on Tuesday that Boeing redesign part of the aircraft's exterior jet engine cover to prevent it from taking off on the aircraft if the fan blade is released on a future flight. It states that all Boeing 737 Next Generation aircraft should be retrofitted with whatever Boeing is repaired.
Boeing has delivered about 6,700 of the 737 NG planes to airlines worldwide, but has stopped accepting new orders for them since moving to the 737 Max. It has less than 1
00 NG aircraft to be built and delivered.
Boeing 737 NG aircraft are unaffected by grounding the 737 Max after two fatal crashes. But the 737 NG had other safety issues, including cracks in some of the older planes of a part used to keep the wings in place. These cracks formed a handful of 737 NG.
The final decision on any amendment depends on the Federal Aviation Administration, not the NTSB, whose role is to investigate the causes of the crashes. But Boeing ( BA ) stated that he was already working to improve engine design to meet NTSB recommendations. And she says that until this check is done, checks on the fan blades will allow planes to operate safely.
"Our common goal is to help prevent such events from happening in the future," the release said.
NTSB blames neither Boeing ( BA ) nor Southwest ( LUV ) the fan blade is not detected and the risk of engine housing release is unknown prior to this incident.
But Boeing's shares fell by 2% as soon as the report was published, although it later recovered much of that loss.
