Engine Safety Enhancement
The NTSB revealed that CFM International engines on Boeing 737 Max planes can accidentally release oil into the hot engine, causing smoke in the cockpit or cabin after a bird strike triggers the safety feature.
Similar engines are used in Airbus A320neo and C919 planes, prompting the NTSB to advise European and Chinese regulators to assess these models for the same issue.
Response and Remediation
CFM, in partnership with Boeing, is developing a software update for the engines, aiming to mitigate the issue by the first quarter of next year, aligning with NTSB recommendations.
The FAA supports the NTSB's recommendations, requiring airlines to implement a permanent fix once available, and has updated pilot checklists to address the smoke issue.
