On most of Boeing’s next-generation narrowbody aircraft, a new problem has arisen. Boeing recommended that 16 customers temporarily park some Boeing 737 MAX aircraft earlier this month pending inspections and rectifications involving an electrical power system part. Although the problem was unexpected, it only affected a small number of MAX jets. However, according to some industry reports, it can affect more jets than previously thought and may spread to other parts of the plane.
According to industry sources, more Boeing 737 MAX aircraft would need to undergo checks than originally expected in order to look for any deficient products that need to be fixed. According to the most recent update, other areas of the 737 MAX aircraft are experiencing electrical system grounding problems. The issue, while not complicated and certainly not to the extent that caused the plane to be grounded for so long, would necessitate some time on the ground. The biggest concern is ensuring that segments of the electrical power grid have ground paths.
Boeing suggested to 16 customers last week that they ground those Boeing 737 MAX aircraft from operations. Customers were instructed to inspect and make any required adjustments to ensure that a part of the electrical power system had a proper ground path. Following Boeing’s announcement, many airlines grounded MAX aircraft from their fleets while waiting for more details. Boeing is working with the Federal Aviation Administration (FAA) in the United States to resolve the issue, which Boeing described as a production issue.
According to Boeing’s phrasing, it’s not a given that the aircraft listed aren’t properly grounded where they should be. As a result, some aircraft would just need to spend some time on the ground for inspection before returning to service. The risk of an electrical failure is not insignificant. This is why Boeing has issued an alert to MAX customers who might be affected. As Boeing and the FAA assess the situation, more information will become available. At this time, the exact number of planes affected by the problems is unclear.
