NTSB issues rare safety bulletin about potential issues with Boeing 737 Max engines

The National Transportation Safety Board (NTSB) has issued a rare and urgent safety bulletin concerning potential hazards associated with the jet engines on Boeing 737 Max aircraft. This recommendation was prompted by two separate incidents involving Southwest Airlines flights that collided with birds, leading to damage in the CFM International LEAP-1B engines. The NTSB's investigation revealed that such damage can allow smoke to infiltrate the aircraft's ventilation system, ultimately reaching the cockpit or passenger cabin. This situation poses an extreme danger in aviation, as smoke can incapacitate pilots, thus compromising flight safety. The NTSB expressed concern that flight crews may not be fully aware of the risks associated with these engine issues and has urged the Federal Aviation Administration (FAA) to take action to ensure that operators inform their flight crews about the potential hazards. Additionally, the NTSB has recommended modifications to the engine software to mitigate these risks.

In response to the NTSB’s findings, Boeing has revised its flight manuals to include specific procedures for pilots aimed at preventing smoke from entering the cockpit or cabin following engine damage. GE Aerospace has also confirmed that it is collaborating closely with Boeing and the NTSB to implement these recommendations, stating that enhancements to the system are already in progress. Boeing has publicly supported the NTSB's recommendation, indicating that its partnership with CFM International is focused on developing a software design update to address these critical safety concerns. The proactive measures being taken by both Boeing and GE Aerospace highlight the industry's commitment to ensuring the safety of the Boeing 737 Max aircraft and its passengers, following the alarming findings of the NTSB.
