Boeing commits to NTSB safety fixes on thousands of 737 NG jets after deadly Southwest engine blast
Boeing on Tuesday said it plans to revamp parts for thousands of 737s after federal safety officials investigating last year’s deadly engine blast on Southwest Airlines flight called for a redesign that would better withstand engine failures in flight...
...Boeing said it commended the NTSB for its investigation and said it is “committed to working closely with the FAA, engine manufacturers, and industry stakeholders to implement enhancements that address the NTSB’s safety recommendations.”
It said “enhancements are being introduced” to inlet and fan cowls to improve “their ability to withstand an engine fan blade out event as well as to increase the overall capability of these structures.”
