The FAA Just Ordered Crack Inspections on 471 American 737 Max Jets. Not One Max Has Actually Cracked.

The Federal Aviation Administration issued an airworthiness directive Thursday requiring operators to inspect hundreds of Boeing 737 Max jets for cracks in a structural reinforcement near the forward galley door, a fix prompted not by anything found on a Max but by cracks discovered on the older 737 models the Max was derived from.

The directive covers the 737-8, 737-9 and 737-8200 — the models sold as the Max 8, Max 9 and Max 8200 — and reaches an estimated 471 aircraft registered in the United States and 1,429 worldwide, according to the FAA. Published in the Federal Register, the order takes effect September 10, 2026, and requires an inspection of the fuselage skin for existing repairs, along with follow-on work depending on what inspectors find.

The part at issue is the "bear strap," a strip of structural reinforcement that frames doorways and emergency exits and carries load around the cutout in the fuselage. Cracks have turned up at the forward upper corner of the forward galley door cutout, on the right side of the airplane. The mechanism is straightforward fatigue: every takeoff and landing pressurizes and depressurizes the cabin, and stress concentrates at door corners. The FAA wrote that the cracking could lead to "the inability of the principal structural element to sustain limit loads" and could compromise the structural integrity of the airplane.

No cracks have been reported on a 737 Max. The findings that triggered the directive came from the 737 Next Generation fleet, the previous-generation jets that entered service starting in the late 1990s and have far more pressurization cycles on them. Boeing said it first notified operators of its 737 Next Generation planes of the issue in 2019, and in 2024 "extended the inspections to 737 MAX airplanes as the model shares a similar design and build process." Thursday's directive converts that voluntary guidance into a legal requirement.

Airlines moved quickly to signal that passengers should not expect disruption. Southwest Airlines, which flies the largest 737 fleet in the world, said it will "accomplish the inspections on the affected airplanes according to the schedule specified by the FAA." United Airlines said the checks would be folded into already-scheduled maintenance and added, "We don't anticipate any impact to our operations in the near term."

The directive lands on a company that has spent seven years cycling through structural and manufacturing scrutiny — the two fatal crashes and 20-month grounding that began in 2018, the door plug that blew off an Alaska Airlines Max 9 in January 2024, and the production caps the FAA imposed afterward. This one is different in kind: it is preventive, driven by fatigue data from an older fleet rather than by an in-flight failure, and the FAA is acting before a Max has shown the defect rather than after.
