Flying while intoxicated (FWI) is a criminal offense under Penal Code § 49.05 — being intoxicated while operating an aircraft. A first offense is a Class B misdemeanor with a 72-hour minimum term of confinement, prior intoxication convictions of any kind raise the grade under § 49.09, and for licensed pilots the parallel FAA certificate action is usually the bigger fight. Below: the controlling statute text, the full punishment range, common defense theories, and what to do if you have been charged in Collin, Dallas, Denton, or Tarrant County.

Controlling statute:Tex. Penal Code § 49.05 · companion offense § 49.065 (amusement rides) Classification: Class B misdemeanor with a 72-hour minimum term of confinement; Class A misdemeanor (30-day minimum) with one prior intoxication conviction; third-degree felony with two priors or one intoxication-manslaughter prior (§ 49.09) Punishment range: Class B — 72 hours to 180 days county jail + fine up to $2,000; Class A — 30 days to 1 year county jail + up to $4,000; third-degree felony — 2–10 years TDCJ + fine up to $10,000
The controlling statute
Texas Penal Code § 49.05 is two sentences long. Subsection (a): “A person commits an offense if the person is intoxicated while operating an aircraft.” Subsection (b): except as provided by § 49.09, the offense is a Class B misdemeanor “with a minimum term of confinement of 72 hours.” The section arrived with the 1994 overhaul that built the modern intoxication chapter (Acts 1993, 73rd Leg., ch. 900, effective September 1, 1994), and it mirrors the DWI statute in structure — same definition of intoxication, same baseline grade, same 72-hour floor.
Three structural features do most of the work in these cases. First, § 49.11 dispenses with a culpable mental state: the State does not have to prove you intended to fly intoxicated, only that you did. Second, § 49.10 strips away the lawful-prescription excuse — being entitled to take the medication that impaired you is expressly not a defense. Third, unlike driving while intoxicated, § 49.05 contains no public-place element. A takeoff from a private grass strip is covered just as fully as a departure from Addison.
One textual quirk favors the defense. Chapter 49 defines “motor vehicle,” “watercraft,” “amusement ride,” and “mobile amusement ride” in § 49.01 — but it never defines “aircraft.” Courts fall back on ordinary meaning, which leaves genuine room to litigate coverage at the margins: gliders, balloons, powered parachutes, and other light craft do not fit the word as obviously as a Cessna does.
Who actually gets charged with flying while intoxicated in Texas?
Almost always general-aviation pilots, and almost never mid-flight. North Texas FWI cases start on the ground at fields like Addison, McKinney National, Dallas Executive, Denton Enterprise, Fort Worth Meacham, and Spinks: a line-service or FBO employee smells alcohol and calls the police, a tower controller or another pilot reports erratic taxiing, or officers respond to a hard landing, a runway excursion, or a gear-up and begin a standard intoxication investigation at the scene. The arrest is made by local police, sheriff’s deputies, or DPS troopers — the FAA has no power to arrest anyone or to prosecute a crime. What the FAA can do, and does quickly, is open a parallel certificate action and refer the criminal side to local authorities.
Prosecutions are genuinely rare. A county-court prosecutor may handle thousands of DWI files before seeing a single § 49.05 case, which cuts both ways: there is no assembly-line plea posture, and neither side has a settled playbook. The offense also reaches only the person operating the aircraft — an intoxicated passenger commits no crime under § 49.05, though a pilot who knowingly carries an obviously intoxicated passenger violates a separate FAA rule, 14 C.F.R. § 91.17(b). Commercial crews answer to an additional layer: operating a common carrier under the influence is a federal felony under 18 U.S.C. § 342, and part 121/135 pilots are subject to DOT/FAA drug-and-alcohol testing programs on top of everything below.
Classification & punishment range
Grading starts at a Class B misdemeanor and climbs through § 49.09’s repeat-offender ladder. The priors that count are not limited to aircraft cases — convictions for operating a motor vehicle, a watercraft, or an amusement ride while intoxicated all feed the same enhancement family.

Two enhancements from the DWI world are conspicuously absent. There is no 0.15 high-BAC bump for aircraft — § 49.04(d) applies only to motor-vehicle cases — and no open-container minimum for aircraft, a floor that exists for cars (§ 49.04(c)) and, oddly, for amusement rides (§ 49.065(c)) but not for § 49.05. The ranges and fine caps above come from Penal Code chapter 12: up to $2,000 for a Class B (§ 12.22), up to $4,000 for a Class A (§ 12.21), and 2–10 years in TDCJ plus up to $10,000 for a third-degree felony (§ 12.34).
Probation does not erase the floors. When a court grants community supervision on a conviction punished under § 49.09(a) or (b), Code of Criminal Procedure article 42A.401 requires a jail stint as a condition of that supervision — at least 72 continuous hours at the Class A level, and at least 10 days at the felony level.
Elements the State must prove
To convict under § 49.05, the State must prove every element beyond a reasonable doubt:
The defendant — identity as the operator, not mere presence in the aircraft
was intoxicated — under either definition in § 49.01(2)
while — the intoxication and the operation must coincide in time
operating — a term Chapter 49 does not define
an aircraft — also undefined in the chapter
Each undefined term is a live issue. “Operating” invites dispute in dual-control aircraft: when a flight instructor and a student, or two rated pilots, are aboard, the State must prove who was actually manipulating the controls — and logbook entries alone do not settle it. “While” is the timing element. Officers usually make contact well after engine shutdown, so the State has to reconstruct intoxication at the moment of operation, not at the moment of the ramp encounter.
A hypothetical shows the timing fight. A pilot lands at Addison at 4:10 p.m., ties down, and has two drinks at the terminal bar while waiting for a ride; police arrive at 5:05 on a report about the rough landing. A 5:40 breath test says very little about 4:10 — the State must prove intoxication while operating, and the documented post-flight consumption becomes the defense’s central exhibit.
Per se vs. impairment: what does “intoxicated” mean in the cockpit?
Section 49.01(2) gives prosecutors two independent routes: the impairment prong — not having the normal use of mental or physical faculties by reason of alcohol, a controlled substance, a drug, a dangerous drug, or any other substance — and the per se prong, an alcohol concentration of 0.08 or more. The 0.08 figure is the same one used for driving; Texas sets no aviation-specific criminal threshold.
The federal number is lower. Under 14 C.F.R. § 91.17(a), no one may act or attempt to act as a crewmember of a civil aircraft within 8 hours of consuming alcohol, while under the influence, while using any drug that affects faculties contrary to safety, or with an alcohol concentration of 0.04 or greater. That gap matters in both directions: a pilot at 0.05 who shows no impairment likely faces no viable Texas per-se case yet sits squarely inside the FAA’s enforcement zone, while the impairment prong can support a Texas conviction with no test at all — or a result below 0.08 — if faculties were demonstrably degraded.
Prescription medication deserves particular caution. The any-other-substance language plus § 49.10’s no-entitlement rule means a lawfully prescribed sleep aid or anxiety medication can carry a case, and the State will pair pharmacy records with the flight timeline to argue degraded faculties. The defense answer is usually attribution and dosage science — what was actually in the blood, at what concentration, with what documented effect — not the prescription itself.
How does the FAA case run alongside the criminal case?
For a certificated pilot, the misdemeanor is often the smaller of the two problems. The FAA does not need a conviction: committing an act prohibited by 14 C.F.R. § 91.17(a) is an independent ground for suspending or revoking any airman certificate, rating, or authorization under 14 C.F.R. § 61.15(b). The agency moves on its own evidence and its own timeline, emergency orders take effect immediately, and appeals go to the National Transportation Safety Board — a forum with different procedures, a different burden, and no jury.
Testing is where the two tracks intersect. Texas’s implied-consent statute does not reach aircraft, but 14 C.F.R. § 91.17(c) requires a crewmember to submit to an alcohol-concentration test requested by a law-enforcement officer investigating a suspected violation of a state or local intoxicated-flying law — and to furnish results to the FAA on request. Refusal is its own ground for denial, suspension, or revocation under 14 C.F.R. § 61.16. The standard DWI-lawyer instinct — politely decline everything — transfers badly to pilots; every refusal decision has to weigh the certificate alongside the criminal case.
Reporting traps come next. The 60-day written-report duty in § 61.15(e) covers motor vehicle actions — car-DWI convictions and driver’s-license actions — not an aircraft arrest, and two motor vehicle actions within three years are independent certificate grounds under § 61.15(d). But the airman medical application asks directly about arrests, convictions, and administrative actions, and a false answer there is a separate federal offense with revocation exposure. Anything said to FAA inspectors or the NTSB is also discoverable by prosecutors, so the criminal defense and the certificate defense have to run as one coordinated matter — statements, pleas, and hearings sequenced deliberately. For airline and charter crews, add 18 U.S.C. § 342 — operating a common carrier under the influence, a federal felony — and DOT testing rules to the stack.
Defense strategies
L and L Law Group builds § 49.05 defenses on the statute’s own pressure points:
“Operating” disputes — dual controls, an instructor aboard, or an arrest made away from the aircraft leaves the State proving who was flying, using a term the Legislature never defined
Timing (“while”) — alcohol consumed after shutdown and before police contact defeats the required coincidence of intoxication and operation; long gaps between flight and specimen undercut retrograde extrapolation
Suppression — with no implied-consent statute for aircraft, a warrantless, nonconsensual blood draw is a prime suppression target under Code of Criminal Procedure article 38.23 absent a warrant or true exigency
Testing attacks — breath-instrument maintenance records, blood chain of custody, lab accreditation, and the disconnect between test time and flight time
Impairment-prong weaknesses — field sobriety tests were validated for roadside traffic stops, not ramp encounters; fatigue, dehydration, and medical conditions supply alternative explanations the State must exclude
Substance attribution — where medication is alleged, dosage, timing, and pharmacology often cannot carry the claim that the drug destroyed normal faculties
Enhancement fights — prior convictions must be valid, final, and properly proved; out-of-state priors must be substantially similar, and the defense can force the State to brief and prove that fit
Enhancements & collateral consequences
Section 49.09 enhances across the entire intoxication family. One prior conviction — a years-old car DWI counts — lifts FWI to a Class A misdemeanor with a 30-day minimum under § 49.09(a). Two priors in any combination, or a single prior for intoxication manslaughter under § 49.08 (including a substantially similar out-of-state conviction), make it a third-degree felony under § 49.09(b). The current statute puts no age limit on qualifying priors, and the street runs both ways: today’s FWI becomes the enhancing prior for any future DWI or BWI.
The supervision rules are harsher than the DWI world’s. Deferred adjudication is categorically unavailable — Code of Criminal Procedure article 42A.102(b)(1)(A) lists § 49.05 and § 49.065 by name, and article 42A.102(b)(1)(C) separately bars deferred for any charge whose punishment may be increased under § 49.09. When the Legislature restored limited deferred eligibility for first-offense driving and boating cases in 2019, flying was left out. Record relief is equally closed: Government Code § 411.0735 expressly excludes § 49.05 convictions from misdemeanor nondisclosure, so a conviction stays on the record permanently. Expunction survives only for the non-conviction endings — acquittal, dismissal without community supervision, or a case never filed.
Two consequences familiar from DWI do not attach here. No driver’s-license suspension flows from the arrest itself — the ALR system in Transportation Code chapters 524 and 724 is tied to motor vehicles and watercraft — and Texas issues no pilot licenses to suspend; that power belongs exclusively to the FAA, which will use it. A felony-level conviction adds the standard stack: firearm disabilities under Penal Code § 46.04 and 18 U.S.C. § 922(g)(1), employment and professional-license fallout, aviation-insurance consequences, and immigration exposure for non-citizens that should be assessed by immigration counsel before any plea. Cases that begin as intoxicated-flying investigations can also grow — a crash with injuries invites intoxication-assault or intoxication-manslaughter charges under §§ 49.07 and 49.08, both far more serious.
What about operating an amusement ride while intoxicated — § 49.065?
The companion offense covers the fairground. Penal Code § 49.065, added in 1999 and effective January 1, 2000, makes it a crime to be intoxicated while operating an amusement ride or while assembling a mobile amusement ride — the Legislature’s response to safety concerns around traveling-carnival crews. “Amusement ride” and “mobile amusement ride” take their definitions from Occupations Code § 2151.002, folded in through § 49.01(5) and (6).
The grading tracks FWI: Class B misdemeanor, 72-hour minimum, full § 49.09 enhancement exposure, and the same deferred-adjudication bar. One quirk is unique to this section — under § 49.065(c), an open container of alcohol in the operator’s immediate possession raises the minimum term to six days, a floor the aircraft statute does not have. Charges cluster around fair season, when mobile rides are assembled and torn down on tight overnight schedules, and the assembly variant means a crew member who never runs the ride can still be charged for putting one together while intoxicated.
What happens after a flying while intoxicated arrest in Collin, Dallas, Denton, or Tarrant County?
The mechanics follow any misdemeanor or felony arrest: book-in at the county jail, magistration and bond, then filing. A Class B or Class A case is filed by information in a county court at law; a § 49.09(b) felony goes to a grand jury and, on indictment, to a district court. Venue follows the airport — a McKinney National or Aero Country case lands at the Russell A. Steindam Courts Building in McKinney; Addison and Dallas Executive cases at the Frank Crowley Courts Building in Dallas; Denton Enterprise cases at the Denton County Courts Building; Meacham and Spinks cases at the Tim Curry Criminal Justice Center in Fort Worth.
Discovery should run wider than in a routine DWI. Under Code of Criminal Procedure article 39.14, the defense obtains offense reports, body-camera footage, and lab records — and in an aviation case it should also move early for FBO surveillance video, fuel and bar receipts, tower or CTAF audio, and ADS-B flight-track data before retention windows lapse. Those sources fix the timeline that the while-operating element depends on.
Limitations run two years for the misdemeanor levels (Code of Criminal Procedure article 12.02) and three years for the felony level (article 12.01). The FAA’s clock is faster on every front, which is why the first week’s decisions — what to say, what to sign, whether to test — should be made with both cases on the table and intoxication-offense counsel already engaged.
Key Legal Terms
Flying While Intoxicated (§ 49.05)
Operating an aircraft while intoxicated; a Class B misdemeanor with a 72-hour minimum term of confinement, enhanceable under § 49.09. Effective September 1, 1994.
Intoxicated (§ 49.01(2))
Not having the normal use of mental or physical faculties by reason of alcohol, a controlled substance, a drug, a dangerous drug, or any other substance — or having an alcohol concentration of 0.08 or more.
Operating
Not defined by Chapter 49. The State argues it reaches engine start, taxi, and run-up; the defense holds the State to proof of actual control of the aircraft by the accused.
§ 49.09 Enhancement
The repeat-offender ladder for intoxication offenses. Priors from any branch — car, boat, aircraft, or amusement ride — count interchangeably, with no age limit on the prior.
The 8-Hour Rule (14 C.F.R. § 91.17(a)(1))
The FAA prohibition on acting or attempting to act as a crewmember of a civil aircraft within 8 hours after consuming any alcoholic beverage — “bottle to throttle.”
Motor Vehicle Action (14 C.F.R. § 61.15(c))
A DWI-related conviction or driver’s-license action that a certificate holder must report to the FAA in writing within 60 days. An aircraft case is not one — but it carries its own certificate consequences.
Amusement Ride (§ 49.065)
Defined by Occupations Code § 2151.002 and incorporated by § 49.01; operating one — or assembling a mobile ride — while intoxicated is the fairground counterpart to FWI.
Frequently Asked Questions
Is it a crime to fly a plane after drinking in Texas?
It is if you are intoxicated while operating the aircraft. Penal Code § 49.05 makes flying while intoxicated a Class B misdemeanor with a minimum term of confinement of 72 hours. Separately, FAA rules prohibit acting as a crewmember within 8 hours of drinking, while under the influence, or at a 0.04 alcohol concentration — a much lower bar than the criminal statute.
Is the legal limit for flying 0.08 or 0.04?
Both numbers matter, in different systems. The Texas crime uses the § 49.01(2) definition — loss of normal mental or physical faculties, or an alcohol concentration of 0.08 or more. The FAA’s civil regulation, 14 C.F.R. § 91.17, bans acting as a crewmember at 0.04 or greater. A pilot who blows 0.05 may face no Texas per-se case yet still lose a certificate.
Will I lose my pilot certificate over a flying while intoxicated case?
You can — and independently of the criminal outcome. Committing an act prohibited by 14 C.F.R. § 91.17(a) is its own ground for suspension or revocation under § 61.15(b), and the FAA does not wait for a conviction. Certificate actions are appealable to the NTSB, and airman medical applications will ask about the arrest and its disposition.
Does a prior DWI in a car enhance a flying while intoxicated charge?
Yes. Section 49.09 counts prior convictions across the whole intoxication family — motor vehicle, aircraft, watercraft, and amusement-ride offenses. One prior makes FWI a Class A misdemeanor with a 30-day minimum. Two priors, or one prior intoxication-manslaughter conviction, make it a third-degree felony carrying 2 to 10 years.
Is there mandatory jail time for flying while intoxicated?
The statute sets floors. A first offense carries a minimum term of confinement of 72 hours; with one prior intoxication conviction the minimum is 30 days. Even when a judge grants community supervision on an enhanced conviction, Code of Criminal Procedure article 42A.401 requires at least 72 hours — or 10 days on a felony-level case — in county jail as a condition.
Can I refuse a breath or blood test after an aviation stop?
Texas’s implied-consent law covers motor vehicles and watercraft, not aircraft, so officers typically need voluntary consent or a search warrant for a specimen. But 14 C.F.R. § 91.17(c) requires crewmembers to submit to testing requested by authorized officers, and § 61.16 makes refusal grounds for certificate suspension or revocation. Refusal decisions have to weigh both tracks.
Is deferred adjudication available for FWI in Texas?
No. Code of Criminal Procedure article 42A.102(b) excludes § 49.05 and § 49.065 from deferred adjudication entirely. First-offense driving and boating cases regained limited deferred eligibility in 2019, but flying while intoxicated was never included, and any charge enhanced under § 49.09 is barred as well.
Can a flying while intoxicated conviction be sealed or expunged?
A conviction cannot be sealed — Government Code § 411.0735 expressly excludes § 49.05 convictions from misdemeanor nondisclosure. Expunction remains possible when the case ends without a conviction: an acquittal, a dismissal without community supervision, or a declined charge can qualify. That gap is one more reason the fight at the charge stage matters.
Do I have to report an FWI arrest to the FAA within 60 days?
The 60-day written-report rule in 14 C.F.R. § 61.15(e) covers motor vehicle actions — car-DWI convictions and driver’s-license actions — and an aircraft case is not a motor vehicle action. But the underlying conduct is already certificate-action grounds under § 61.15(b), and the next airman medical application will require honest answers about arrests and convictions. Get aviation-specific advice before filing anything.
What is assembling or operating an amusement ride while intoxicated?
Penal Code § 49.065 is the companion offense: operating an amusement ride, or assembling a mobile amusement ride, while intoxicated. It is a Class B misdemeanor with a 72-hour minimum — six days if an open container is in the operator’s immediate possession — and it enhances under § 49.09 exactly like DWI, BWI, and FWI.
