Boeing may need to redesign 7,000 jets after a fatal crash last year



A single passenger was killed on the plane when a fan blade broke and caused part of the engine cover to reach the side of the jet. This broke one of the windows and the cabin quickly depressurized. The crew managed to land the plane, but the woman sitting by the window was killed.

The National Transportation Safety Council, which investigated the crash, recommended on Tuesday that Boeing redesign part of the aircraft's jet engine's outer cover to prevent it from flying into the plane if a fan came off on a future flight. . He said that all Boeing 737 Next Generation Series aircraft must be adapted with any correction Boeing may make.

Boeing delivered about 6,700 of the 737 NG jets to airlines around the world, but stopped receiving new orders for them when it moved to 737 Max. It still has fewer than 100 NG planes to be built and delivered.

Boeing 737 NG aircraft were unaffected by the grounding of the 737 Max following two fatal accidents. But the 737 NG had other safety issues, including cracking some of the older planes, in a part used to keep the wings in place. These cracks landed a handful of 737 GN.
The final decision on any correction rests with the Federal Aviation Administration, not the NTSB, whose function is to investigate the causes of the accidents. But Boeing (BA) said it is already working on engine design improvements to meet NTSB recommendations. And until this correction is applied, fan blade inspections will allow aircraft to operate safely.

"Our common goal is to help prevent similar events from happening in the future," he said.

NTSB didn't blame Boeing (BA) nor South-west (LUV), saying that the crack in the fan blade was undetectable and that the risk of the engine casing breaking free was unknown prior to this incident.

But Boeing shares fell as much as 2% immediately after the report was released, although it later recovered much of that loss.
