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.

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.

The FAA evaluated bird strike concerns on Boeing 737 MAX engines, opting not to require immediate action. The review board found no urgent issue, though further assessments and procedure amendments are being considered.

The Federal Aviation Administration plans to convene a corrective action 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 NTSB’s decision to open a formal investigation into a December 2023 bird strike involving a Southwest Airlines Boeing 737 MAX 8 will add scrutiny to the rarely needed safety device triggered during the incident that some FAA experts and pilots believe creates unacceptable risk.

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.
