FAA Confirms Structural Cracking in Airbus Cargo Doors — Validating Earlier Warnings by QA Expert and Boeing Shareholder Daryl Guberman

FAA's New Airworthiness Directive Confirms the Exact Structural Door Weakness Guberman Identified in Earlier Public Warnings

The Federal Aviation Administration has issued a new Notice of Proposed Rulemaking (NPRM) addressing structural cracking in the upper forward and aft corners of Airbus A320/A321 bulk cargo doors, confirming the exact type of fatigue‑related failure long identified by aerospace quality expert Daryl Guberman.

The proposed Airworthiness Directive (Federal Register Document No. 2026‑08594 (https://www.federalregister.gov/documents/2026/05/04/2026-08594/airworthiness-directives-airbus-sas-airplanes ) cites fatigue‑test findings showing cracks forming around fastener holes in the cargo‑door structure — a door assembly composed primarily of aluminum with localized reinforcement, consistent with Guberman's prior public analysis of door‑plug vulnerabilities across the industry.

Guberman previously published findings related to the January 5, 2024 Alaska Air door‑plug failure, identifying manufacturing performed in an uncertified environment and highlighting the systemic risks of weakened oversight across both Boeing and Airbus supply chains.

"This is precisely what I warned about — aluminum door structures under cyclic stress (on going vibration) will crack, and the regulators are now acknowledging it," said Guberman.

The FAA's NPRM- mandates conditional repairs, and potential cold‑working (strengthening the metal by squeezing it) of fastener holes to restore structural integrity. The agency notes that unaddressed cracking could compromise the aircraft's structural safety envelope.

"This new FAA action validates the core issue: when certification systems fail, metal fatigue wins — and passengers pay the price," Guberman added.

Historical FAA Notifications Warning Airbus About Fastener‑Hole Fatigue Cracking (2000–2024)

The newly proposed 2026 directive is only the latest in a long chain of FAA warnings issued to Airbus over more than two decades. These directives repeatedly identified fatigue cracking around fastener holes, frame feet, and fuselage structural joints on A319/A320/A321 aircraft:

• 2000 — FAA AD 2000‑12‑04
• 2014 — FAA AD 2014‑15‑16
• 2022 — FAA AD 2022‑14‑10
• 2024 — FAA AD 2024‑05‑02
• 2025–2026 — FAA Proposed AD 2025‑01379 / 2026‑08594

These FAA notifications demonstrate a clear, documented pattern:

Airbus was warned in 2000, 2014, 2022, 2024, and now again in 2025–2026 about fatigue‑related cracking around drilled fastener holes.

SECTION: Boeing Oversight and Structural‑Integrity Implications

As part of this broader industry‑wide structural‑integrity discussion, Boeing must also be addressed. As a Boeing shareholder and long‑time quality professional, Daryl Guberman emphasizes that the FAA's newly proposed Airbus directive is not an isolated event — it is part of a systemic pattern across the entire aerospace sector where fatigue‑critical structures, drilled fastener holes, and aging airframes continue to reveal vulnerabilities. This includes heat treatment and welding which are flight critical processes.

Boeing has faced its own series of FAA actions over the past decade involving structural fastener‑hole cracking, manufacturing deviations, and quality‑system breakdowns, including:

• 2019 — 737NG pickle‑fork cracking
• 2020–2021 — 787 fuselage join nonconformities
• 2024 — FAA oversight findings following the Alaska Airlines door‑plug separation

Each of these events involved structural interfaces, fastener‑hole stress concentrations, or quality‑system lapses — the same categories of risk now highlighted in the Airbus cargo‑door cracking directive.

The Accreditation Collapse Affecting Both Boeing & Airbus

Guberman stated:

"Airbus is now facing the same physics Boeing faced — and still faces. When you drill holes into aluminum or composite structures and then subject them to vibration, pressurization, and cyclic:(on going vibration) loading, fatigue is inevitable unless oversight is airtight. Boeing's history shows what happens when oversight weakens. Airbus is now learning the same lesson." Guberman sent a warning letter to Airbus in September 11, 2025.

He added:

"As a Boeing shareholder, I expect Boeing to treat this Airbus directive as a mirror — not a shield. This is not the time for competitive relief. It is the time for structural honesty."

Closing Statement

"I've said it before, and I'll say it again: when you drill a hole in a vibratory environment, you create a stress‑concentration point. Over time, cracks will form. This is predictable, preventable, and inspectable — but only if the industry takes these warnings seriously. For decades, especially when it came to Boeing, both Boeing and the FAA made the general public and government think that an airworthiness certificate superseded AS9100 — but they were wrong, "DEAD WRONG!"

"The world is rarely healed by institutions. It is healed by the one individual who sees the wound clearly enough — and cares deeply enough — to close it.
I have seen the wound.
I have mapped the fracture.
I am offering the repair."
