Introduction to the Issue
The National Transportation Safety Board issued a rare, urgent security bulletin warning of potential problems with the jet engines on Boeing 737 Max aircraft. This recommendation was inspired by two incidents on flights from Southwest Airlines that encountered birds.
The Problem with Jet Engines
The NTSB found problems with CFM International Leap-1B engines, which can lead to smoke entering the ventilation system and ultimately the cockpit or passenger cabin. This is a significant concern because smoke in the cockpit is classified as an extreme danger in aviation, as it can overpower and incapacitate pilots.
Concerns and Recommendations
The NTSB is concerned that flight crews operating these aircraft may not be completely aware of the potential danger. As a result, the agency calls on the Federal Aviation Administration to ensure that operators inform aircraft crews with the engines concerned. The NTSB also recommends changes to the engine software to mitigate this risk.
Response from Boeing and GE Aerospace
Boeing has revised flight manuals for pilots, detailing steps to prevent smoke from entering the cockpit or cabin after such damage. GE Aerospace stated that it had already made changes in response to the NTSB’s recommendations. In a statement, Boeing expressed support for the NTSB recommendation, noting that CFM International and Boeing are working on a software design update.
Conclusion
The NTSB’s urgent security bulletin highlights the importance of addressing potential safety issues in the aviation industry. The responses from Boeing and GE Aerospace demonstrate a commitment to resolving the problem and ensuring the safety of passengers and crew.
