What Disqualifies You from Being a Commercial Pilot?

What disqualifies you from being a commercial pilot falls into a handful of categories: failing an FAA medical exam, certain criminal convictions, alcohol- or drug-related incidents, falling short of the required flight hours, prior FAA enforcement history, falsifying an application, and inability to meet the English language standard. Some of these are permanent bars. Many are not. The FAA regularly certificates pilots with treated medical conditions, past DUIs, and even histories of substance dependence, provided the pilot follows the right process.

Medical Conditions That Fail the Exam

A commercial pilot needs at least a second-class medical certificate issued under 14 CFR Part 67, and an airline transport pilot flying under Part 121 needs a first-class medical renewed every 12 months.¹ The exam is conducted by an FAA-authorized Aviation Medical Examiner (AME).

The FAA lists specific automatically disqualifying conditions:²

Cardiovascular: angina pectoris, coronary heart disease that has been treated or symptomatic, heart replacement, cardiac valve replacement, permanent cardiac pacemaker, or history of myocardial infarction
Neurological: epilepsy, unexplained disturbance of consciousness, or unexplained transient loss of nervous system function
Psychiatric: psychosis, bipolar disorder, or a severe personality disorder shown through overt acts
Substance abuse or substance dependence
Diabetes mellitus requiring insulin or other blood-sugar-lowering medication

Vision and hearing are separate hurdles. Color blindness and significant uncorrected vision problems are common reasons applicants fail. For a first-class medical you need 20/20 distant vision in each eye (corrective lenses count) and normal color perception.³

Obstructive sleep apnea is disqualifying until treated. A body mass index of 40 or higher will trigger a mandatory sleep evaluation, and physical features like a large tongue, enlarged tonsils, or a receding jaw can also prompt a referral at lower BMIs. Certification returns once you show effective treatment, typically documented through CPAP compliance data.⁴

Depression is not a permanent bar, but the path is narrow. The FAA permits certain antidepressants through a Special Issuance protocol only when the diagnosis is mild-to-moderate major depressive disorder, dysthymic disorder, or adjustment disorder with depressed mood; you’ve been stable on a single approved medication at a consistent dose for at least three continuous months; and you have no history of psychosis, suicidal thoughts, or electroconvulsive therapy.⁵ Evaluation by a HIMS-trained AME is required, and multi-drug psychiatric regimens are not permitted. Pilots on unapproved psychiatric medications are grounded until they transition or discontinue under medical supervision.

Special Issuance Waivers

For most disqualifying conditions, the Federal Air Surgeon can grant a Special Issuance Medical Certificate if you show the condition is stable and safe. The process requires detailed treatment records, specialized evaluations, and sometimes a medical flight test. Approved certificates typically carry more frequent renewals and monitoring conditions.⁶ Neuropsychological testing and psychiatric evaluations for this process often run $2,200 to $10,000 out of pocket, and health insurance rarely covers FAA-specific evaluations.

Alcohol and Drug Problems

This is the area where more pilots lose careers than any other, often not because of addiction but because of paperwork.

Operating Limits

You cannot act as a crewmember within eight hours of any alcoholic drink, while under the influence, while using any impairing drug, or with a blood or breath alcohol concentration of 0.04 percent or greater.⁷ That threshold is half the legal driving limit in most states, and many airlines impose a 12-hour “bottle to throttle” policy on top of the eight-hour minimum.

The 60-Day Reporting Rule

Any alcohol- or drug-related motor vehicle action — a DUI, DWI, implied-consent refusal, or administrative license suspension — must be reported in writing to the FAA within 60 days. A second motor vehicle action within three years of a prior one is grounds for denial of your certificate for up to a year, or suspension and revocation of any certificate you hold.⁸ Failing to report at all carries the same consequences.⁹ The FAA cross-references state DMV records, so a missed notification rarely stays hidden and always makes things worse.

Drug Convictions and Test Refusals

A conviction for any federal or state drug offense — growing, manufacturing, selling, possessing, or transporting controlled substances — is grounds for denial for up to one year or revocation of an existing certificate.⁸ Pilots at airlines and other regulated carriers are also subject to DOT-mandated testing under 49 CFR Part 40, covering pre-employment, random, post-accident, reasonable-suspicion, and return-to-duty tests.¹⁰

Refusing a blood-alcohol test requested by law enforcement, or refusing to release test results when the FAA asks, is treated as seriously as a positive result: denial of any certificate for up to a year, or suspension and revocation.¹¹

Coming Back Through HIMS

A substance abuse or dependence diagnosis doesn’t have to end a career. The FAA’s Human Intervention Motivation Study (HIMS) program coordinates identification, treatment, and a monitored return to flying.¹² For substance dependence, the FAA requires at least two continuous years of complete abstinence with clinical evidence of recovery before it will consider recertification. Expect ongoing monitoring, regular check-ins with a HIMS AME, peer support, and several thousand dollars in evaluation costs.

Criminal History

A felony conviction doesn’t automatically block a commercial pilot certificate, but a criminal record can affect you in two separate places: FAA certificate review and TSA airport access.

FAA Review

Drug convictions follow the specific denial and revocation rules above. Other crimes are evaluated case by case, weighing the nature and severity of the offense, how recently it happened, and your broader compliance record. Convictions involving violence, fraud, or dishonesty draw the closest scrutiny, and the FAA looks at patterns rather than isolated incidents.¹³

TSA SIDA Badge Disqualifiers

Even with an FAA certificate in hand, you need a Security Identification Display Area (SIDA) badge to work at most airports, and the TSA runs its own background check. Some offenses are permanently disqualifying regardless of how long ago they occurred: espionage, treason, federal crimes of terrorism, murder, and offenses involving explosives or transportation security incidents.¹⁴

A second tier disqualifies you if the conviction or guilty plea happened within seven years of your application, or if you were released from incarceration within five years. That list includes robbery, arson, kidnapping, aggravated sexual abuse, firearms offenses, extortion, smuggling, fraud and identity theft, immigration violations, and distribution of controlled substances.¹⁴ TSA can also deny clearance based on mental health adjudications — specifically, court or government findings that a person poses a danger, or involuntary psychiatric commitment.

Not Enough Flight Hours

You cannot test for the commercial certificate without at least 250 hours of flight time for an airplane rating (150 hours for helicopters). The composition matters: at least 100 hours in powered aircraft (50 in airplanes), 100 hours as pilot in command including 50 hours of cross-country flying, 20 hours of specific training (10 of them instrument training), and 10 hours of solo flight that includes a 300-nautical-mile cross-country trip.¹⁵

Falling short on any of these thresholds is probably the most common practical barrier for aspiring commercial pilots. It’s not a disqualifying event so much as a gap that takes years and significant money to close. Note that flying for a Part 121 airline requires an ATP certificate on top of the commercial, which generally means 1,500 total hours, with reductions for military pilots and certain aviation degree graduates.

Age Limits

You must be at least 18 to hold a commercial pilot certificate.¹⁶ Federal law also bars pilots from serving in Part 121 airline operations after their 65th birthday, and the same cap applies to certain large Part 135 operators that logged 75,000 or more turbojet operations in 2019 or any subsequent year.¹⁷ There is no FAA age ceiling for corporate aviation, smaller charter operations, most Part 135 cargo, or flight instruction. Proposals to raise the airline retirement age to 67 have surfaced in Congress but none have been enacted as of early 2026.

Prior Enforcement and Application Falsification

A previously suspended or revoked FAA certificate follows you. The FAA issues fixed-term suspensions to discipline violations, indefinite suspensions when a pilot must re-prove qualification, and revocations when the agency decides you’re not qualified to hold any certificate.¹³ After a revocation you generally wait at least a year before reapplying, and the FAA scrutinizes whatever caused the original action.

Falsifying any information on an FAA application — medical, certificate, or logbook — is among the fastest routes to losing everything. The FAA treats intentional falsification as grounds for immediate revocation, and it poisons future applications because your credibility is now in question. Pilots have lost careers over the concealment rather than the underlying issue.

English Language Proficiency

Every FAA pilot certificate applicant must read, speak, write, and understand English.¹⁶ Proficiency is checked starting at the student pilot application and assessed again at every practical test against the FAA’s Aviation English Language Standard.¹⁸ Foreign-trained pilots converting a license must meet the same standard, with the minimum set at ICAO Language Proficiency Operational Level 4. Applicants who cannot meet the requirement because of a medical condition such as hearing loss may receive a certificate with operational limitations rather than an outright denial.¹⁹
