NEW YORK: US regulators said they continue to work with Boeing to assess an electrical problem that has grounded more than a hundred 737 MAX planes, as airlines expressed hope for a speedy resolution. The problem, which surfaced during Boeing’s manufacturing process, has so far not significantly affected airlines given the still-lackluster travel volume during Covid-19, but demand is expected to pick up significantly this summer. The Federal Aviation Administration (FAA) described the problem as “an electrical bonding and grounding issue,” according to an agency notice to civil aviation authorities.
