What Happens If You Let Your Part 107 Recurrent Training Expire (2026 Guide)

Imagine this: you booked a $2,500 roof inspection gig for Thursday, you pull up your Part 107 card on Tuesday to send proof to the client, and you realize your 24-month currency ran out three weeks ago. You are not current. You are not legal to fly commercially. And you are not alone — this exact scenario plays out in the drone subreddits every single week.

If you have ever wondered what happens if you let your Part 107 recurrent training expire, the short version is sobering: the moment your 24-month recency of aeronautical knowledge lapses, you lose the legal right to fly a drone for any commercial purpose. No grace period. No warning email from the FAA. No buffer days. You are grounded for compensation work until you complete the free online recurrent course.

This guide breaks down exactly what changes the second your currency expires, how the 24-month rule actually works, what fines and enforcement risks you face, and how to get current again in under two hours using the FAA’s free ALC-677 course. We pulled details from the FAA’s own FAQ pages, the lived experience of pilots in r/drones, and the official FAASafety.gov training portal so you do not have to piece it together yourself.

Whether you are two days past your expiration date or two years past it, the path back to legal commercial flying is the same — and it is faster, cheaper, and less painful than most pilots expect. Let’s walk through it.

The Quick Answer: No Grace Period, No Penalty to Renew

If you let your Part 107 recurrent training expire, you are immediately prohibited from flying commercially until you complete the free ALC-677 online recurrent course on FAASafety.gov. Your actual Remote Pilot Certificate stays permanent, but your operating currency disappears the day after the 24-month window closes.

There is no grace period. There is no late fee. There is no requirement to retake the full $150 initial knowledge test. Even if your currency has been lapsed for years, the fix is identical: log into FAASafety.gov, take the free ALC-677 course, pass the open-book exam with a 100% score, and download your new Certificate of Completion.

Where you can get into real trouble is flying commercially during the gap. The FAA can impose civil penalties up to $27,500 per violation under 49 U.S. Code 46301, and insurance carriers routinely deny claims if the pilot was not current at the time of an incident. The renewal itself is painless. The risk is in ignoring the lapse and flying anyway.

Certificate vs Currency: The Distinction That Confuses Everyone

The single biggest source of confusion in the drone community is the difference between a Part 107 certificate and Part 107 currency. The FAA’s own FAQ page gets flooded with this question, and the FAA explicitly states: “Your certificate is permanent unless revoked by the Administrator.”

That plastic card in your wallet does not have an expiration date printed on it because the certificate itself does not expire. What expires is your recency of aeronautical knowledge — the FAA’s term for staying up to date on regulations, airspace, weather, and operations through recurrent training every 24 calendar months.

Think of it like a driver’s license that never expires, paired with an insurance policy that must be renewed every two years. The license stays valid forever, but you cannot legally drive without current insurance. Same concept: your certificate is forever, your currency is the operational permission that has to be refreshed.

This distinction matters because pilots see “no expiration date” on their card and assume they are fine forever. They are not. They are fine to hold the certificate forever, but the moment their 24-month currency lapses, they cannot legally act as remote pilot in command of a small UAS under Part 107.

Side-by-Side Comparison

Remote Pilot Certificate: Permanent credential issued by the FAA Airman Registry. Never expires unless surrendered, suspended, or revoked. Printed on a plastic card with your name, certificate number, and issue date — but no expiration date.

Recency of Aeronautical Knowledge (Currency): A rolling 24-calendar-month window during which you are legal to operate commercially under Part 107. Refreshed by completing recurrent training (ALC-677 for most pilots, ALC-515 for Part 61 certificated pilots). If it lapses, commercial flying privileges pause until you renew.

Forum posts in r/drones consistently show pilots panicking that they will “lose their Part 107” if they miss the deadline. You will not lose the certificate. You will only lose the operating privileges until you complete a free online course.

How the 24-Month Recency Requirement Actually Works

The FAA’s recency rule lives in 14 CFR 107.65, and it operates on a calendar month system rather than a strict 24-months-to-the-day countdown. This trips up a lot of pilots because the math is not as simple as adding two years to your issue date.

Under the calendar month rule, your currency is valid until the end of the 24th calendar month after the month you completed your last training event. So if you passed your initial knowledge test on March 8, 2024, your currency runs through the last day of March 2026 — not March 8, 2026. That extra three weeks of cushion is the end-of-month rule working in your favor.

Here is the part competitors consistently underexplain: when you renew early, your new 24-month clock resets from the date of your new training, not your original issue date. So if you complete ALC-677 in January 2026 even though your current currency does not expire until March 2026, your next renewal deadline becomes January 2028. Renewing early gives you a fresh full 24 months from that point.

End-of-Month Calculation Examples

If you completed recurrent training on November 12, 2026 minus 2, your currency expires at the end of November 2026. Not November 12. Not mid-November. The last day of November.

If you completed it on February 3, your currency expires at the end of February two years later. Even though February only has 28 (or 29) days, you get the full calendar month.

If you completed it on the very last day of a month — say July 31 — your currency still expires at the end of July two years later. The rule is calendar month based, not day based, so completing training on the 1st or the 31st of a month produces the same expiration window.

This is also why the FAA does not print an expiration date on the card: the date depends on when you completed training, not when the certificate was issued, and it changes every time you renew.

What Happens If You Let Your Part 107 Recurrent Training Expire

Here is the moment-by-moment breakdown of what happens if you let your Part 107 recurrent training expire — both the immediate regulatory impact and the real-world ripple effects.

You Lose Commercial Operating Privileges Immediately

The instant your 24-month recency window closes, you are no longer legally authorized to act as remote pilot in command of a small UAS for any operation governed by Part 107. This includes any flight where you receive compensation, any flight in furtherance of a business, and any flight that contributes to a paid service like real estate photography, roof inspections, mapping, wedding videography, agricultural surveying, or construction monitoring.

You are not “mostly legal” or “legal with restrictions” during the gap. You are fully prohibited from Part 107 operations. Period.

The Certificate Is Not Revoked

Your Remote Pilot Certificate itself remains valid and on file with the FAA Airman Registry. The FAA does not revoke, suspend, or cancel certificates for currency lapses. You will still show up in the FAA’s airman database as a certificated remote pilot. The credential is permanent under 14 CFR 107.61.

This is the silver lining that anxious pilots overlook: missing your renewal deadline does not mean starting over from scratch with the initial knowledge test. It means completing the same free online course you would have taken on time.

FAA Civil Penalties Up to $27,500 Per Violation

If you fly commercially with an expired Part 107, each flight can be treated as a separate violation under 49 U.S. Code 46301 and 14 CFR Part 107. The FAA’s published civil penalty range for small UAS regulatory violations runs up to $27,500 per violation, with criminal penalties possible in cases involving reckless operation or endangerment of life or property.

Real enforcement examples shared by pilots in forums include warning letters, certificate actions, and proposed fines that were negotiated down to four-figure settlements. The FAA tends to escalate when an incident — a crash, a near miss, a complaint from a manned aircraft pilot — triggers an investigation that reveals the pilot was not current.

Insurance Coverage Collapses

This is the consequence most pilots underestimate. Drone insurance policies almost universally require that the named pilot be in compliance with all applicable FAA regulations at the time of any incident. If your Part 107 currency has lapsed and you crash into a car, injure someone, or damage property during a commercial flight, your insurer has grounds to deny the claim.

Some policies go further and require pilots to provide updated proof of currency at policy renewal. If you cannot produce a current Certificate of Completion, the insurer can refuse to renew coverage or require you to complete recurrent training before reinstating the policy.

Client Gigs Disappear

Smart commercial clients — especially real estate brokerages, construction firms, insurance adjusters, and government contractors — ask for proof of Part 107 currency before signing a contract. Many pilots on r/drones have shared stories of losing four- and five-figure gigs because their currency lapsed between the proposal and the shoot date.

One recurring pattern: a pilot lets currency lapse, books a gig assuming they will “renew next week,” and the client requests proof of currency on Monday for a Tuesday shoot. The pilot cannot get through the ALC-677 course, exam, and certificate download in time. The gig goes to a competitor who kept their currency current.

No Penalty for Late Renewal Itself

The FAA does not impose any penalty, surcharge, or extra requirement for renewing late. Whether you renew one day after expiration or five years after expiration, the process and the cost (zero dollars) are identical. Pilots on Reddit regularly confirm they let currency lapse for two, three, even five years and renewed simply by completing ALC-677.

The penalty is not for letting it lapse. The penalty is for flying while lapsed. Do not confuse the two.

Can You Fly With an Expired Part 107? Commercial vs Recreational

This is the question that dominates forum threads: if my Part 107 currency is expired, can I still fly my drone at all? The answer splits cleanly down the commercial-versus-recreational line.

Commercial Flying: Prohibited

You cannot fly commercially under Part 107 while your currency is expired. This includes any flight where compensation is involved, any flight supporting a business activity, any flight that contributes to a paid deliverable, and any flight where the aircraft itself is being used for business purposes — even if no money changes hands on that specific flight.

“But I’m just practicing for a future gig” is not a defense. Practice flights that build skills for paid work count as commercial preparation. The FAA looks at the purpose and context of the flight, not just whether cash was exchanged that day.

Recreational Flying: Allowed Under Section 44809 and TRUST

Here is the relief valve most anxious pilots do not know about: you can still fly recreationally while your Part 107 currency is expired. Recreational drone operations fall under 49 U.S. Code 44809, which is a separate legal framework from Part 107 and does not require a Remote Pilot Certificate.

To fly recreationally, you need to complete the free TRUST (The Recreational UAS Safety Test) administered through an FAA-approved test administrator like the AMA, Boy Scouts, or Drone Launch Academy. TRUST takes about 15 minutes, is free, and never expires. With TRUST complete, you can fly within the recreational limits — line of sight, under 400 feet in uncontrolled airspace, within visual range, and following community-based safety guidelines.

Many pilots use this recreational window to keep flying for fun during a brief currency gap. The catch: the moment any compensation or business purpose enters the picture, you are back in Part 107 territory and you must have current Part 107 currency.

The “Will the FAA Know?” Question

Pilots often ask whether the FAA actively monitors for expired Part 107 pilots who keep flying commercially. The honest answer: the FAA does not have a real-time tracking system that flags every flight by a non-current pilot. Enforcement typically happens reactively — triggered by a complaint, an incident, an accident report, an insurance claim, or a pattern noticed during a targeted inspection.

That said, the FAA has access to LAANC data, Remote ID broadcasts, incident reports, and insurance filings. If something goes wrong during a commercial flight — even something minor like a neighbor complaint — and the investigation reveals you were not current, you face the full enforcement pipeline. The risk is not constant monitoring. The risk is the day something goes sideways.

How to Renew Your Expired Part 107: Step-by-Step ALC-677 Guide

Whether you are renewing on time or years late, the renewal process is the same free online course through FAASafety.gov. Here is the exact step-by-step walkthrough that works in 2026.

Step 1: Confirm Which Course You Need

Most Part 107 pilots need ALC-677 (Small UAS Recurrent). This is the free online course hosted on FAASafety.gov that fulfills the 14 CFR 107.65 recency requirement for non-Part-61 pilots.

If you also hold a Part 61 pilot certificate (manned aircraft) with a current flight review, you instead take ALC-515, which is shorter and tailored to pilots already current on manned-aircraft regulations. ALC-515 covers only the small UAS-specific topics that differ from general aviation.

Step 2: Log Into FAASafety.gov

Go to FAASafety.gov and sign in using your FAA Airman Registry credentials. If you have never created an account, you will need to register using the same name and certificate number shown on your Remote Pilot Certificate. Name mismatches between your FAASafety.gov account and your airman record are a common snag — the system uses your name match to link your training completion back to your airman file.

Many pilots report recent FAASafety.gov password requirement changes that lock them out. If you cannot log in, use the password reset flow and check that your new password meets the updated complexity rules before retrying.

Step 3: Enroll in ALC-677

From the FAASafety.gov homepage, navigate to the Courses tab, search for “ALC-677” or “Small UAS Recurrent,” and click Enroll. The course is free. There is no in-person component. There is no proctored testing center. The entire course and exam happen online through your browser.

Step 4: Complete the Course Modules

ALC-677 includes updated modules covering airspace classifications, operating rules, weather effects on small UAS, crew resource management, emergency procedures, aeronautical decision-making, airport operations, night operations (new since the 2021 rule update), and recent regulatory changes. Each module is a self-paced presentation with embedded review questions.

The course is open book — you can pause, look things up, and return to earlier modules at any time. Most pilots complete the modules in 60 to 90 minutes if they are already familiar with Part 107 material. Newer pilots or those renewing for the first time often take 2 to 3 hours.

Step 5: Pass the 45-Question Exam

After completing all modules, you take the final exam: 45 multiple-choice questions drawn from the course material. You need a 100% passing score to receive your Certificate of Completion. The exam is open book, untimed in the sense that you can stop and resume later, and allows unlimited attempts — if you miss a question, you can review the relevant module and try again.

The 100% requirement is not a typo. Unlike the initial Part 107 knowledge test (70% passing score), the recurrent online course requires a perfect score because you can retake it as many times as needed. The FAA reasons that an open-book test with unlimited attempts should yield a perfect score eventually.

Step 6: Download and Save Your Certificate of Completion

The instant you pass the exam, FAASafety.gov generates a PDF Certificate of Completion showing your name, certificate number, course name (ALC-677), completion date, and a unique completion ID. Download this PDF immediately. Save copies to your computer, your phone, your cloud storage, and email a copy to yourself.

This certificate is your proof of currency. The FAA does not mail a new plastic card. There is no updated airman certificate. The Certificate of Completion is the document clients, insurers, and the FAA itself will reference if anyone asks for proof that you are current.

ALC-677 vs ALC-515 at a Glance

ALC-677 (Small UAS Recurrent): For pilots who hold a Part 107 Remote Pilot Certificate but do not hold a current Part 61 pilot certificate with a flight review. Free. Online. 45-question exam, 100% required. Approximately 90 to 180 minutes total.

ALC-515 (Part 61 Pilots): For pilots who hold both a Part 107 certificate and a current Part 61 pilot certificate with a current flight review. Free. Online. Shorter content focused on small UAS-specific rules. Same Certificate of Completion process.

Both courses are hosted on FAASafety.gov, both are free, and both produce a Certificate of Completion that satisfies the 14 CFR 107.65 recency requirement for 24 calendar months from the date of completion.

How to Check Your Renewal Deadline Before It Passes

The FAA does not send renewal reminder emails. There is no FAA app that pings you. The entire burden of tracking your 24-month deadline falls on you. Here are three reliable ways to find your expiration date.

Method 1: Check Your Last Certificate of Completion

Look at the date on your most recent ALC-677 or ALC-515 Certificate of Completion (or your initial knowledge test report if you have not yet renewed). Add 24 calendar months, and round up to the last day of that month. That is your expiration date.

For example: a Certificate of Completion dated April 15, 2026 minus 2, means your currency expires on April 30, 2026. Write that date down somewhere permanent.

Method 2: Check FAASafety.gov Activity History

Log into FAASafety.gov and look at your training activity history. Every ALC course you have completed appears there with a completion date. Use the most recent applicable course date as your starting point for the 24-month countdown.

Method 3: Set Calendar Reminders 60 and 30 Days Out

The single most reliable strategy pilots on r/drones recommend is setting two calendar alerts — one 60 days before your expiration and one 30 days before. Use Google Calendar, Apple Calendar, Outlook, or any calendar app that syncs across your devices. The 60-day reminder gives you time to complete the course without rushing. The 30-day reminder is your backup if life got in the way.

Some pilots also set a 7-day final reminder as a panic trigger. Whatever cadence you choose, do not rely on memory alone. Two years is a long time, and the FAA’s silence on reminders is not an oversight — they expect certificated pilots to track their own currency.

Special Situations and Edge Cases

Not every Part 107 holder fits the standard renewal path. Here are the special situations that generate the most forum confusion.

Part 61 Pilots (ALC-515 Pathway)

If you hold a manned-aircraft pilot certificate under 14 CFR Part 61 with a current flight review, your renewal pathway is ALC-515 instead of ALC-677. ALC-515 covers only the small UAS-specific content that differs from general aviation knowledge. It is shorter and assumes you already understand airspace, weather, and aeronautical decision-making from your manned-aircraft training.

Pre-2021 Certificate Holders Who Have Never Done Recurrent

Pilots who earned their Part 107 certificate in 2016 or 2017 — the first cohorts under Part 107 — and have never completed recurrent training are technically long past their 24-month deadline. The good news: the renewal path is identical. You take ALC-677 online for free, pass the exam, and your currency resets from that completion date. There is no back-penalty and no requirement to retake the initial $150 knowledge test.

Pre-2021 vs Post-2021 Renewal Process

Before April 2021, recurrent training required scheduling an in-person appointment at an FAA-approved testing center and paying for a proctored exam. The FAA’s rule change in 2021 moved the entire process online through FAASafety.gov, made it free, and dropped the testing-center requirement. If you renewed before 2021 and have not renewed since, your next renewal will be a completely different — and much easier — experience.

International or Foreign-Based Pilots

Foreign pilots who obtained a U.S. Part 107 Remote Pilot Certificate follow the same renewal process as U.S. citizens: log into FAASafety.gov, complete ALC-677, and download the Certificate of Completion. There is no separate international renewal pathway.

Name Mismatches Between FAASafety.gov and Airman Registry

A common renewal snag: the name on your FAASafety.gov account does not match the name on file with the FAA Airman Registry. This can happen after a legal name change, a typo during initial registration, or a difference in how you entered your name on each platform. If your completion does not appear linked to your airman record, contact the FAA Airman Registry to reconcile the names before completing renewal.

Drone Registration Is a Separate 3-Year Cycle

Do not conflate Part 107 currency with drone registration. Your aircraft registration through the FAA DroneZone is a separate three-year cycle independent of your pilot currency. A current Part 107 does not make an unregistered drone legal, and a registered drone does not make an expired Part 107 pilot legal for commercial operations. Track both deadlines separately.

Recordkeeping After Renewal: Save the Right Documents

Once you complete ALC-677, the FAA does not issue a new plastic card and does not update your Remote Pilot Certificate. Your proof of currency lives entirely in your Certificate of Completion PDF. Treat that document like gold.

Save the PDF in at least three places: your computer’s local storage, a cloud backup like Google Drive or Dropbox, and your phone for quick access in the field. Email a copy to yourself at an address you check regularly so you can retrieve it from any device.

Pilots who fly commercially for clients should also keep proof ready to send within minutes of a request. Real estate agents, construction managers, insurance adjusters, and government contractors increasingly request proof of Part 107 currency as part of their vendor onboarding. Having the PDF ready in a folder you can attach to an email wins gigs.

For pilots managing a fleet or a team, store each pilot’s current Certificate of Completion in a shared drive organized by pilot name and expiration date. Set a master calendar reminder for each pilot’s renewal 60 days in advance so no one on the team flies expired.

Common Scams to Avoid

Every few months, a new wave of scam websites appears promising “official Part 107 renewal cards” or “expedited Part 107 recurrency processing” for a fee. The FAA’s recurrent training process is and always has been free through FAASafety.gov. Any website asking for payment to “renew” your Part 107 is either a third-party prep course (legitimate, but not required) or an outright scam.

Legitimate paid options include Part 107 study guides, prep courses, and practice exams from established training providers. These can help you prepare for ALC-677, but they are not required and they do not replace the free FAASafety.gov course itself. Never pay for a “renewal card” or a “recurrency certificate” — the only valid Certificate of Completion comes directly from FAASafety.gov after you pass the ALC-677 exam.

Pro Tips: Making Renewal Painless Next Cycle

The pilots who never stress about Part 107 currency build simple systems. Here is what consistently works based on forum reports and pilot interviews.

Renew early. You do not have to wait until the final month. Renewing a month or two early resets your 24-month clock to the new date and gives you a buffer if FAASafety.gov has an outage or you have a busy stretch.

Pair renewal with another annual habit. Some pilots renew their Part 107 currency in the same month they renew their drone insurance or their aircraft registrations. Stacking the deadlines makes them easier to remember.

Use the FAA WINGS program. The WINGS program on FAASafety.gov tracks your training activities and sends optional notifications about upcoming currency deadlines. It is free and integrates with your airman record.

Add the Certificate of Completion to your flight apps. Apps like Aloft and ForeFlight let you attach pilot credentials to your profile. Some pilots store their current certificate PDF in these apps so it is accessible from the field during a ramp check.

Update your client-facing documents after every renewal. Replace any outdated Certificate of Completion you have shared with clients, insurers, or platforms so they always have your current proof on file.

FAQ’s

Conclusion: Knowing What Happens If You Let Your Part 107 Recurrent Training Expire Keeps You Flying

Understanding what happens if you let your Part 107 recurrent training expire comes down to three core facts: there is no grace period, there is no penalty for renewing late, and there is no shortcut around flying commercially while your currency is lapsed. The moment your 24-month window closes, commercial operations stop until you complete the free ALC-677 course on FAASafety.gov.

Your Remote Pilot Certificate itself is permanent. The FAA does not revoke it, does not charge a late fee, and does not force you to retake the initial knowledge test. Renewal is the same free online course whether you are one day late or five years late. The risk lives entirely in flying during the gap — civil penalties up to $27,500 per violation and insurance claims denied on the spot.

Set a calendar reminder 60 days before your expiration date. Renew early if you can. Save your Certificate of Completion in three places the moment you pass the exam. Treat your currency like a vendor deliverable, because that is exactly what clients, insurers, and the FAA treat it as.

Take the ALC-677 course today if your currency has lapsed, and put the next renewal date on your calendar before you close the browser tab. Two years goes faster than you think.
