NTSB issues urgent safety bulletin about engines found in some Boeing 737 Max jets

The NTSB issued an urgent safety recommendation to modify CFM International LEAP-1B engines on Boeing 737 Max aircraft after two incidents where bird strikes triggered a load reduction device, damaging the engine oil system and causing smoke to enter the cockpit and cabin; the FAA and Boeing agreed with the recommendations and have alerted airlines, while CFM and Boeing are developing a software update to address the issue, impacting shares of Boeing (BA), GE Aerospace (GE), Safran (SAFRY), and Southwest Airlines (LUV).

Analysis

The National Transportation Safety Board (NTSB) has issued an urgent safety recommendation for modifications to CFM International LEAP-1B engines, predominantly found on Boeing 737 Max aircraft, following two incidents in 2023 involving Southwest Airlines planes where bird strikes triggered engine damage and subsequent smoke in the cockpit and cabin. The NTSB identified that a load reduction device, a safety feature in these engines, can inadvertently damage the engine's oil system after a bird strike, leading to oil release and smoke generation. This development, carrying a 'moderately negative' sentiment score of -0.5, contributed to a 1.26% decline in Boeing (BA) shares to $197.73 and a 0.80% drop in Southwest Airlines (LUV) shares to $31.17. The NTSB has also recommended evaluating CFM’s LEAP-1A and LEAP-1C engines, used in some Airbus A320neo and COMAC C919 jets, for similar vulnerabilities. Both the Federal Aviation Administration (FAA) and Boeing have concurred with the NTSB's findings, with Boeing and CFM (a joint venture of GE Aerospace and Safran Aircraft Engines) reportedly working on a software design update. Despite negative per-ticker sentiment for GE Aerospace (GE, -0.5) and Safran (SAFRY, -0.5), their shares saw modest gains, with GE up 0.11% to $235.92 and SAFRY up 1.12% to $75.03, possibly reflecting market parsing of long-term engine program value against near-term remediation costs. This situation compounds existing scrutiny on Boeing's manufacturing and safety protocols and indicates potential rectification costs and operational adjustments for affected entities.

Key Decisions for Investors

• Investors in Boeing (BA) should closely monitor the timeline and financial implications of the required engine modifications, as this adds further pressure to the company's ongoing operational and reputational challenges.
• Shareholders of GE Aerospace (GE) and Safran (SAFRY), as co-owners of CFM International, need to assess the potential costs associated with the engine fixes and any broader impact on the LEAP engine family's market perception.
• For Southwest Airlines (LUV), investors should consider potential near-term impacts including heightened maintenance expenses and possible, albeit temporary, aircraft availability issues related to its significant 737 Max fleet.
