Boeing discovered another problem in some of its 737 fuselages that could delay deliveries of about 50 aircraft in the latest quality gaffe to plague the manufacturer.
Improperly drilled holes were discovered by Spirit AeroSystems, a major supplier that provides Boeing with fuselages, according to a letter from Stan Deal, CEO of Boeing’s commercial airplanes division.
“While this potential condition is not an immediate safety issue and all 737s can continue operating safely, we currently believe we will have to perform rework on about 50 undelivered planes,” Deal said in a letter to employees shared Monday.

Boeing and Spirit AeroSystems face intense scrutiny over the quality of their work after an Alaska Airlines 737 Max 9 was forced to make an emergency landing on Jan. 5 when a panel called a door plug blew out of the side of the plane shortly after takeoff from Portland, Oregon.

Alaska Airlines and United Airlines, the only other U.S. airline flying the Max 9, reported finding loose hardware in door plugs of other planes they inspected after the accident. The FAA grounded all Max 9s in the U.S. the day after the blowout. Two weeks later, the agency approved the inspection and maintenance process to return the planes to flying.

Boeing, based in Arlington, Virginia, said last week it withdrew a request for a safety exemption needed to certify a new, smaller model of the 737 Max airliner. Boeing asked federal regulators late last year to allow delivery of its 737 Max 7 airliner to customers even though it does not meet a safety standard designed to prevent part of the engine housing from overheating and breaking off during flight.
