Manufacturing issue put some Boeing 737 Max out of service

It was not until the end of last year that the Boeing 737 Max put back into service, but the long-struggling passenger jet ran into another problem. Through Reuters, U.S. airlines have temporarily grounded more than 65 737 Max jets after Boeing notified 16 carriers of a manufacturing issue that could affect the model’s standby power control unit.

The problem is not related to the Maneuver Characteristics Augmentation System (MCAS) software which grounded the 737 Max for nearly two years after being linked to two fatal crashes that killed 346 people. According to Reuters, the problem affects around 90 aircraft. Southwest Airlines has removed 30 of its 737 Max jets from its flight schedule, most of all US carriers. Boeing has reportedly told airlines that the refit of the affected plane could take anywhere from a few hours to a few days. “Boeing has recommended 16 customers resolve a potential electrical issue in a specific group of 737 Max aircraft before continuing operations,” the company said. said in a press release. “The recommendation is made to verify that a sufficient earth path exists for a component of the power supply system.”

An analyst Reuters spoke to suggested that the issue is unlikely to be a design oversight given that it appears to only affect a portion of all Max jets currently in service. Still, it’s another setback for an aircraft that has already had its share of high-profile problems.
