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.

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 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.

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 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 FAA is weighing new takeoff instructions for Boeing 737 MAX pilots to avoid a risk of smoke in the cabin or flight deck if an engine is hit by a bird.
