A significant software issue in the Boeing 737 MAX has raised concerns regarding pilot safety and operational efficiency during critical flight manoeuvres. Specifically, the glitch could disrupt automated flight guidance when pilots execute a go-around, a necessary response during missed landings. Both Boeing and the Federal Aviation Administration (FAA) are currently collaborating on a solution, with the expectation of a permanent software update being implemented by early 2028.

Reports indicate that the problem arises after a missed approach when flight crews attempt to adjust their flight pathways. This malfunction compromises the autopilot system, compelling pilots to revert to manual control, which can be particularly taxing given the busy nature of flight operations. Industry insiders have noted the potential for distractions at a crucial moment in the flight, with one source expressing concern over the increased workload on flight crews during these critical scenarios.
In an official communication, the FAA confirmed its awareness of “potential issues” related to the software used in specific Boeing 737 MAX models. The agency stated that it is actively engaging with Boeing and airline operators to address this matter. The FAA plans to establish a Corrective Action Review Board (CARB) to evaluate the situation closely and will take prompt measures should any safety issues arise.
Boeing asserted that it first became aware of the glitch in November 2024, following feedback from one of its operators; however, it initially deemed the matter not significant enough for a safety review. After collecting further information from affected airlines, Boeing initiated a formal safety review this month and promptly shared its findings with the FAA. The company has committed to expediting the necessary software amendments.
The aerospace giant reassured stakeholders that existing pilot training equips them to land safely without reliance on the automated vertical navigation systems that have been impacted by this software issue. Boeing has also reiterated that it is working diligently on an update to rectify the glitch permanently. In an internal notice to operators in August, Boeing indicated that further guidance would be issued by November, with the comprehensive software fix anticipated to roll out by early 2028.
Despite the complications presented by this software flaw, airlines including Alaska, American, Southwest, and United have stated their fleets remain unaffected. Boeing has advised airlines to revert to a previous iteration of the software whilst the issue is being resolved. Industry experts have expressed that some carriers are reluctant to accept new deliveries of aircraft that may be equipped with this problematic software.
This development comes on the heels of the recent FAA certification of the 737 MAX 7, which permits Boeing to market this variant of their widely used aircraft. However, major carriers like Southwest and United Airlines, which have been awaiting their MAX 7 orders for some time, have reportedly communicated to Boeing their refusal to accept the deliveries if the planes are fitted with the flawed software.
The certification of the MAX 7 had previously faced delays following two catastrophic crashes of the MAX 8 model in 2018 and 2019, which tragically resulted in the deaths of 346 individuals. These incidents compelled the FAA to reassess and tighten the certification process for Boeing aircraft. In addition, the company has faced scrutiny following a significant mid-air incident in January 2024, where a cabin panel blew out on a new Alaska Airlines MAX 9.
As part of the revised certification requirements, the FAA mandated several key enhancements to the aircraft, encompassing updates to the flight control software and improvements to the flight crew alerting system. These modifications are designed to provide pilots with clearer information and to mitigate risks, such as overheating of engine inlets due to anti-icing systems.
Boeing is also seeking certification for the MAX 10, the fourth and largest variant in the MAX family. Reports indicate that the firm has already constructed 30 units of the MAX 7 and nine units of the MAX 10, with the MAX 10 comprising a substantial portion of Boeing’s outstanding orders.
As the situation continues to unfold, the collaboration between Boeing, airlines, and regulatory authorities remains critical in ensuring the safety and efficiency of the 737 MAX fleet. The industry’s focus now shifts towards expediting the software corrections and maintaining operational integrity amid ongoing service commitments.
