WASHINGTON: The National Transportation Safety Board issued an urgent safety recommendation Wednesday to address the possibility of smoke entering the cockpit or cabin of Boeing 737 MAX airplanes equipped with CFM International LEAP-1B engines.
The NTSB also recommended evaluating the potential for the same issue with LEAP-1A and LEAP-1C engines, which are used on some Airbus A320neo variants and COMAC’s Chinese-made C919 jets.
The recommendation comes after two incidents involving Southwest Airlines Boeing 737 MAX jets that experienced bird strikes in 2023. The NTSB wants the Federal Aviation Administration to ensure that operators inform flight crews of airplanes equipped with the affected engines.
Southwest said it is reviewing the recommendations and that it has mitigation procedures currently in place. Southwest notified its flight crews about the effects of certain bird strikes following two events that occurred in 2023, reiterating the importance of following established safety procedures.
CFM, the world’s largest engine maker by units sold, is co-owned by GE Aerospace and Safran.
