A single passenger was killed in the plane when a fan blade broke and a part of the engine cover hit the side of the jet. As a result, one of the windows was broken and the cabin quickly depressurized. The crew could land the plane, but the woman sitting next to that window was killed.
The National Road Safety Authority, which investigated the accident, recommended on Tuesday that Boeing rebuild a portion of the aircraft's engine cowlings to prevent them from flying into the aircraft if a fan blade detaches on a future flight. It was said that all Boeing 737 Next Generation aircraft should be retrofitted with any Boeing-equipped kit.
Boeing has delivered some 6,700 of the 737 NG jets to airlines around the world, but has not accepted new orders since it switched to the 737 Max. There are still fewer than 1
00 NG aircraft to be built and delivered.
Boeing 737 NG aircraft were not affected by two deadly crashes from grounding the 737 Max. However, the 737 NG had other safety issues, including the discovery of cracks on some of the older aircraft on a part used to hold the wings. These cracks have created a handful of the 737 NGs.
The final decision on a solution lies with the Federal Aviation Administration, not the NTSB, whose job it is to investigate the causes of accidents. Boeing ( BA ) stated, however, that it was already working on improvements to engine design to accommodate the NTSB's recommendations. And as long as the fault has not been rectified, inspections of the fan blades ensure safe operation of the aircraft.
"Our common goal is to prevent similar events from happening in the future".
The NTSB Neither Boeing  ( BA ) nor Southwest ( LUV ) is blamed for this Undetectable and the risk of breaking the motor housing was not known before this incident.
Immediately after the release of the report, Boeing's shares fell by up to 2%, although this loss was later largely offset.
