U.S. air safety officials have asked Boeing Co to provide new analyzes and documents showing that many 737 MAX subsystems will not be affected by the first flagged electrical grounding problem. Of the three areas of the aircraft in April, two people familiar with the matter told Reuters.
Further analysis raises new uncertainty at the time that Boeing’s best-selling jetliner will be flown by the United States Aviation Administration (FAA).

Electrical problems have suppressed nearly a quarter of the 737 MAX fleet.
U.S. airlines said they expect Boeing to release a service statement as soon as this week, allowing them to fix and return the aircraft as soon as possible. But this latest issue is likely to push that time back.
“We continue to work closely with the FAA and our customers to resolve the impact of the 737s on land routes,”; a Boeing spokeswoman said.
Asked about the aircraft’s status, an FAA spokesperson said, “We are continuing to work with Boeing.”

The airline pulled several 737 MAX jets from service earlier this month after Boeing warned of production-related grounding issues in a spare power regulator located in the aircraft’s cockpit. Some ships that were just built
The issue, which also disrupted shipments of the new aircraft, was then found in two other locations on the flight deck, including a storage rack that holds the affected control unit and the pilot-facing instrument panel.
The glitch is the latest to plague the 737 MAX, which has been based for nearly two years, starting in 2019 after two fatal crashes.

Late last week, Boeing sent a service bulletin to advise airlines on how to tackle grounding or electrical routing issues designed to keep it safe in the event of a voltage surge.
The FAA has approved a service statement. But in ongoing discussions with Boeing has asked for further analysis on whether other jet subsystems will be affected by grounding issues, the sources said, the FAA will review Boeing’s analysis and Amendments required to the service bulletin before sending to the airline.
Boeing has proposed to add harnesses or cables that workers screw to two different surfaces to create a grounding path, the two said.
Boeing initially told the airline the fix could take hours or a few days on a single plane.
The grounding issue came after Boeing changed its manufacturing methods as it worked to speed up production of the jet, a third-party said. A fourth person said the change improves the hole punching process.

The FAA issued a new airworthiness directive last week that needed a fix before the jets flew on, saying the issue affected 109 aircraft serving the world, the source said, affecting the planes. More than 300 ships in Boeing inventory
