A technical review by the FAA decided the risk from an engine vulnerability does not warrant immediate action, contrary to an internal report last month.

The FAA Corrective Action Review Board reviewed the CFM LEAP-1B engine bird strikes which led to smoke entering two Boeing 737 MAX aircraft. The board determined the issue does not warrant immediate action and the FAA will follow its standard regulatory process to address it, the agency said.

An internal memo recommends a design change to fix an engine risk on the 737 MAX, in addition to informing pilots of the risk and changing takeoff procedures.

The FAA is considering new takeoff instructions for pilots of Boeing 737 Max jets to prevent smoke from entering the cabin if a bird flies into the engine.
