NTSB issued an urgent safety recommendation to address the possibility of smoke entering the cockpit or cabin of airplanes equipped w/
$GE CFM International LEAP-1B engines & issued additional recommendations to evaluate the potential for the same issue w/ LEAP-1A & -1C engines.
CFM LEAP engines are used on variants of Airbus A320neo &
$BA 737 Max jets
The NTSB found that the engine load reduction device (LRD), a safety feature designed to reduce the severity of vibrations transmitted from a damaged engine to the airframe, can result in damage to the engine oil system. Such a condition can allow smoke from hot oil to enter the ventilation system & ultimately the cockpit or passenger cabin
The recommendations stem from the NTSB’s investigation into a Dec 2023 incident in which smoke entered the airplane after a bird was ingested into the left engine of a
$LUV Boeing 737-8 shortly after departing New Orleans. A similar engine damage event occurred in March 2023 on another Southwest flight
