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.

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.

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.

In March 2023, a Southwest Airlines aircraft was forced to turn back to Havana José Martí International Airport (HAV). The 737 MAX 8 , registered as N8792Q, operating flight WN3923, suffered a bird strike and had to return to Havana.
