US carriers remove some 737 Max from service due to ‘power control unit’ issue By Jon Hemmerdinger9 April 2021 www.flightglobal.com/airframers/us-carriers-remove-some-737-max-from-service-due-to-power-control-unit-issue/143241.articleBoeing resumed 737 Max deliveries after the Federal Aviation Administration (FAA) lifted the type’s grounding in November 2020.
“Last night, Boeing notified us of a potential production issue with a component in the electrical power system on 17 of our most recently delivered Boeing 737 Max,” American says. “At Boeing’s direction, we have temporarily removed these 17 aircraft from service in order to complete necessary inspections and make any changes recommended or required by Boeing or the Federal Aviation Administration.”
Another 24 of American’s 737 Max “are not affected by this issue, as they were produced and delivered prior to the un-grounding”, American says. “We will continue to work with the FAA, Boeing and our union leaders and their safety teams as a thorough assessment of the issue is completed.”
Boeing disclosed on 9 April that it had recommended that 16 airlines “address a potential electrical issue in a specific group of 737 Max airplanes prior to further operations”.

Boeing wins FAA OK for 737 MAX electrical fix, notifies airlines www.reuters.com/article/us-boeing-737max-exclusive/boeing-wins-faa-ok-for-737-max-electrical-fix-notifies-airlines-idUSKBN2CU08EAn FAA official confirmed that the agency had approved the service bulletins and associated instructions. Boeing sent two bulletins to air carriers on Wednesday on the fixes. “After gaining final approvals from the FAA, we have issued service bulletins for the affected fleet,” Boeing told Reuters. “We are also completing the work as we prepare to resume deliveries.” Reuters reported on May 4 that the FAA asked Boeing to supply fresh analysis showing numerous 737 MAX subsystems would not be affected by electrical grounding issues first flagged in three areas of the jet in April. The electrical issue emerged after Boeing changed a manufacturing method as it worked to speed up production of the jetliner, a third person said. A fourth person said the change improved a hole-drilling process. Airlines pulled dozens of 737 MAX jets from service in early April after Boeing warned of the electrical problem, linked to a backup power control unit in the cockpit on some recently built airplanes. The problem, which also halted delivery of new planes, was then found in two other places on the flight deck, including the storage rack where the control unit is kept and the instrument panel facing the pilots.
The FAA said other carriers affected include Cayman Airways, Copa Airlines, GOL Linhas Aereas, Iceland Air, Minsheng Leasing, Neos Air, Shanding Airlines, SilkAir, Spice Jet, Sunwing Airlines, TUI, Turkish Airlines, Valla Jets Limited, WestJet Airlines and Xiamen Airlines.
