National Transportation Safety Board (NTSB) issued an immediate security recommendation on Wednesday to revise the jet engine Boeing’s 737 Max Airplanes to prevent smoke from entering the cockpit or cabin in some scenarios.
Warning comes after two incidents Southwest Airlines CFM-equipped planes equipped with International Leap-1B engines that experience bird attacks in 2023.
NTSB stated that these CFM engines have a safety facility, called a load reduction device, once active after a bird strike can inadvertently damage the oil system of engines. As a result of the damage, the hot oil released in the engine can create smoke and ultimately enter the ventilation system and the cockpit or passenger cabin.
NTSB investigated an incident in December 2023 that included a south -west airlines aircraft that hit a bird flying from New Orleans. The aircraft landed quickly after “white white smoke” and filled the cockpit and was so fat that the captain said that the instrument panel was difficult to see.

Nine months ago, another incident was associated with similar engine damage, which took place from Havana in Cuba and on a South -West flight, when the birds were included in an engine immediately after the takeoff, resulting in the smoking cabin.
In both cases, flights landed safely, and no one was injured.

NTSB also recommended to evaluate the capacity for the same issue with CFM’s Leap-1A and Leap-1C engines, which have been used by the Commercial Aircraft Corporation on some Airbus A320NEO aircraft and C919 jet. China,
CFM is owned by Ge Aerospace and Safran aircraft engine.

The FAA said, “We advised the operators to evaluate their processes and the training of the crew to address this possible issue.” “When the engine manufacturer develops a permanent mitigation, we will need to apply it to operators within a reasonable time frame.”
