Tech News: Manufacturing issue has forced Boeing to pull some 737 Max planes from service.
It wasn’t until late last year that the Boeing 737 Max was put back into service, but the passenger plane that has been in trouble for so long has another problem. According to Reuters, US airlines temporarily grounded more than 65 737 Max aircraft after Boeing notified 16 airlines of a manufacturing issue that could affect the model’s reserve power control unit.
The problem is unrelated to the Maneuvering Characteristic Augmentation System (MCAS) software that 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 about 90 aircraft. Southwest Airlines has taken 30 of its 737 Max out of service, most of any US airline.
Boeing reportedly told airlines that retrofitting of affected planes could take anywhere from several hours to several days. “Boeing has recommended that 16 customers address a potential electrical problem in a specific group of 737 Max aircraft before continuing to fly,” the company said in a statement. “The recommendation is made to verify that there is a sufficient ground path for a component of the electrical power system.”
An analyst Reuters spoke to suggested the problem is unlikely to be a design flaw, as it appears to affect only a fraction of all Max jets currently in service. However, it’s another setback for an aircraft that has already had its share of high-profile problems.
