The Federal Aviation Administration said on Tuesday it will not require any immediate action after convening a review board to consider concerns about Boeing 737 MAX engines after two bird strike incidents on Southwest Airlines planes in 2023.

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.

US regulator the Federal Aviation Administration (FAA) will take no immediate action to address a smoke-related issue involving the CFM International Leap-1B engines that power the Boeing 737 Max.

The FAA Corrective Action Review Board, after reviewing the CFM LEAP-1B engine bird strikes, which eventually led to smoke entering the aircrafts, said that the issue does not warrant an immediate action. The agency will therefore follow standard regulatory processes to address them, Reuters reported.

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.

Boeing’s (BA) long, difficult year kicked off with a 737 Max door plug blowout, and now a new part is drawing scrutiny from federal investigators. Reuters reports that the Federal Aviation Administration is looking into problems with the planes’ engines after a pair of bird strikes last year aboard a pair of Southwest Airlines (LUV) flights.

The Federal Aviation Administration plans to convene a review board in the coming weeks to consider safety concerns about engines on Boeing 737 MAX airplanes after two bird strike incidents on Southwest Airlines planes in 2023.

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.
