Failed the Part 107 Test? The 14-Day Wait, Your Test Report and a Retest Plan
After a failed Part 107 test, 14 CFR 107.71 makes you wait 14 calendar days. You bring the failed test report, need no instructor endorsement, and pay for a new appointment. Here is how to count the days, read the ACS codes on your report, and use the wait well.
Short answer
If you fail the Part 107 knowledge test, 14 CFR 107.71 says you may not reapply for 14 calendar days. To retest, book a new PSI appointment, pay the test fee again, and bring the failed Airman Knowledge Test Report, which the test center scans as your authorization. No instructor endorsement is needed. Part 107 sets no limit on the number of attempts. Use the ACS codes printed on your report to see which knowledge areas cost you points, and spend the 14 days on those.
A failed Part 107 test is a two-week delay, not a setback to your eligibility. The rule is short, the paperwork is one document, and the report you were handed tells you more about where to aim than the score does.
The Part 107 retest rules in one place
| Question | Official answer | Source |
|---|---|---|
| How long must I wait? | 14 calendar days after failing | 14 CFR 107.71 |
| What authorizes the retest? | The failed Airman Knowledge Test Report (AKTR), presented at the test center | FAA testing matrix, PSI bulletin |
| Do I need an instructor endorsement? | No, "no instructor endorsement or other form of written authorization is required to retest AFTER FAILURE" | FAA testing matrix |
| Do I pay again? | Yes, a retest is a new appointment with its own fee; the FAA says centers charge about $175 | FAA cost FAQ, ACS Appendix 1 |
| Is there a limit on attempts? | Part 107 sets none; 107.71 only sets the waiting period | 14 CFR 107.71 |
| Does my test change? | The FAA says the sequence and wording of questions vary between tests | FAA testing FAQ |
The no-endorsement rule is worth noticing: several pilot knowledge tests in the same FAA matrix require an instructor's statement after a failure. The UAG doesn't.
Counting the 14 calendar days
107.71 says an applicant who fails "may not reapply for the test for 14 calendar days after failing the test." Calendar days include weekends and holidays.
A worked example with dates chosen for illustration: if you fail on Monday, November 2, 2026, the 14 calendar days after it run from November 3 through Monday, November 16. Booking for Tuesday, November 17 or later keeps you clearly outside the waiting period under either reading of "after." If you're unsure which first date counts, ask PSI when you book (844-704-1487).
What your failed Part 107 score report tells you
The FAA's testing FAQ says the AKTR shows your name, FAA Tracking Number and score, plus Airman Certification Standards (ACS) codes "related to any questions you may have answered incorrectly." The FAA doesn't release live questions, so the report points to topics, not to the questions themselves.
Each code has four parts. The ACS's own example:
- UA: the ACS (Unmanned Aircraft Systems)
- I: the area of operation (Regulations)
- B: the task (Operating Rules)
- K10: the knowledge element (visual line of sight operations)
Look each code up in the ACS document, FAA-S-ACS-10B. A few examples of where codes lead:
| Code | ACS knowledge element | Where to study it |
|---|---|---|
| UA.I.B.K21 | Operating limitations: groundspeed, altitude, visibility, cloud clearance | 14 CFR 107.51 |
| UA.I.E.K13 | Declaration of compliance (operations over people) | 14 CFR 107.115 to 107.165 |
| UA.II.B.K2 | ATC authorizations and related operating limitations | 14 CFR 107.41 and AC 107-2A |
| UA.III.A.K2 | Aviation routine weather reports (METAR) | Remote Pilot Study Guide, chapter 3a |
| UA.IV.A.K2 | Using performance data to calculate the effect on performance | Remote Pilot Study Guide, chapters 4 and 8 |
| UA.V.D.K4 | Hazardous attitudes | Remote Pilot Study Guide, chapter 10 |
Then group your codes by area of operation (the Roman numeral). Under PSI's 2025 specifications, Regulations (I) is 48% of the test, Operations (V) 25%, Airspace (II) 20%, Weather (III) 5% and Loading and Performance (IV) 2%. Several codes in a heavy area matter more than one code in a light one.
Once full prep opens, every question you miss waits in Fix It, planned for full Part 107 prep, until you get it right.
Keep a copy of the failed Part 107 report
The FAA's matrix tells proctors to scan the failed AKTR you present, confirm it was stored electronically, and then destroy it. Make a copy or photo before test day so you keep your list of codes. If you've already lost the original, the FAA says tests taken on or after January 13, 2020 can be reprinted from your PSI account.
Bring the same kind of ID as the first time. PSI's bulletin says you may forfeit your chance to test if you don't present proper identification or authorization, which can cost you the new fee.
A 14-day Part 107 retest plan
A practical schedule for about an hour a day. It's editorial advice, not an FAA requirement:
| Days | What to do |
|---|---|
| 1–2 | List your ACS codes, look each up, group them by area, and rank the areas by share of the test |
| 3–6 | Work through the heaviest area on your list, reading the rule or chapter behind each code before you practice |
| 7–9 | The next areas on your list. If any code starts with UA.II, add chart drills on a current sectional |
| 10 | Declarations of compliance and operations over people, the UAG topic the FAA reports as missed most often |
| 11–12 | A timed mixed set of 60 questions in 2 hours, then review every miss |
| 13 | Only the codes you're still missing |
| 14 | Light review, check your ID and pack the failed report |
If you want to repeat your misses in a different format, Redemption challenges planned for Part 107 prep revisit the questions you missed. The free Part 107 retake planner works today: tell it which areas you found hard and it fits a week-by-week plan into the time before your retest.
What a failed Part 107 attempt does and doesn't mean
Some calm facts:
- It's common enough. The FAA's 2025 statistics show an 82.96% pass rate on UAG tests, so roughly one test in six didn't pass (Passy's arithmetic).
- It doesn't affect eligibility. Nothing in 14 CFR 107.61 counts failed attempts against you.
- It doesn't predict the retest. The FAA says the sequence and wording of questions vary from test to test, and two weeks of targeted study changes what you know.
- A near miss is still a near miss. 41 of 60 is 68.3%, and the line is 70%. If your score was close, the format and passing score guide shows exactly where the line sits.
When you rebook, think about how much time you really need. The 14 days are a minimum, not a deadline, and the Part 107 study plan guide has longer schedules. If you'll want paid practice for a short retest window, a 30-day access period at $19.99 is planned for Part 107 prep, and the Part 107 test cost guide covers the fee and cancellation rules for the new booking.
