Redefining “Dependence”: How the FAA Uses Outdated Standards and Irrelevant Proxies to Control Careers

Modern psychiatry has evolved. The FAA’s framework often has not. When outdated terminology and ground-based legal events are used as substitutes for current medical evidence, careers can be controlled by labels that no longer reflect modern science.

---

In medicine, definitions evolve. They evolve with research, evidence, and a better understanding of human health.

But within the FAA’s HIMS program, a critical question has emerged: What happens when a regulatory agency relies not only on outdated medical concepts—but also on non-medical proxies—to make life-altering decisions?

That is exactly what is happening with the FAA’s continued use of “alcohol dependence” and its reliance on driving records as evidence of medical risk.

Modern Medicine Has Moved On

In clinical practice today, substance-related conditions are defined by the DSM-5. The DSM no longer recognizes “alcohol dependence” as a standalone diagnosis.

Instead, it uses a broader framework: Substance Use Disorder (SUD), with subtypes such as Alcohol Use Disorder (AUD).

• Clearly defined criteria
• A 12-month evaluation window
• A spectrum of severity (mild to severe)

It also explicitly recognizes remission, recovery, and improvement over time.

👉 In modern medicine, diagnosis is current, contextual, and evidence-based.

The FAA’s Definition: A Legacy Framework

The FAA continues to rely on “substance dependence” under 14 CFR Part 67—a term rooted in an outdated diagnostic model that modern psychiatry has abandoned.

Yet within the FAA system, “dependence” remains:

• A trigger for HIMS entry
• A basis for ongoing surveillance
• A label that is difficult—if not impossible—to remove

Driving Records vs. Medical Reality

The FAA’s reliance on driving-related events introduces a deeply problematic layer.

• DUI or DWI arrests
• High BAC readings
• License actions

These are often treated as evidence of underlying medical conditions.

But these are:

• Legal events
• Context-specific
• Moment-in-time occurrences

—not medical diagnoses.

Under modern standards: 👉 A diagnosis requires patterns, criteria, and clinical evaluation—not a single incident.

A Critical Disconnect

Driving and flying are fundamentally different:

• Driving is unsupervised and personal
• Flying is regulated and continuously evaluated

Pilots are already subject to:

• Random testing
• Medical certification
• Operational oversight

👉 These systems directly assess fitness to fly.

So why is a past driving event being used as a proxy for a medical condition that must be clinically demonstrated?

Where the System Breaks Down

• Outdated Medical Definitions
• Legal Events Used as Medical Evidence
• Past Incidents Over Current Reality
• Recovery Without Recognition

The Authority Question

The FAA’s mandate is safety—but safety must be grounded in accurate, modern medical assessment.

Instead, the current system reflects broad discretion, limited transparency, and a departure from accepted medical standards.

From Safety Tool to Catch-All Mechanism

When outdated definitions combine with irrelevant proxies, the system expands.

“Dependence” becomes easier to assign, harder to challenge, and nearly impossible to escape.

The Human Impact

Pilots with:

• Years of sobriety
• No current diagnosis
• Strong performance records

Remain under indefinite monitoring because of a legacy label tied to past events.

Conclusion

Safety demands rigor—but rigor requires:

• Scientific accuracy
• Fair application
• Clear boundaries between law and medicine

Because when those lines blur—careers are not just regulated. They are controlled.
