What Happens If You Fail the Part 107 Test?

Updated 2026-10-17. Independent guide, not affiliated with the FAA.

Short answer: You can retake it as many times as you need, but you must wait 14 calendar days after a fail (14 CFR 107.71), pay the testing fee again (about $175), and bring your failed Airman Knowledge Test Report (AKTR) to the testing center. No instructor endorsement is required. Your AKTR lists the knowledge areas you missed, so use it to plan the 14 days.

What are the Part 107 retake rules?

Rule	Detail	Source
Waiting period	14 calendar days after the failed test	14 CFR 107.71: ecfr.gov
Instructor endorsement	Not required for a UAG retest	FAA Airman Knowledge Testing Matrix: faa.gov
What to bring	Your failed AKTR plus valid photo ID	Same matrix; 14 CFR 107.67
Fee	Paid again at each attempt (about $175 at PSI)	PSI scheduling
Limit on attempts	No limit in the rule	14 CFR 107.71

How do I read my failed test report?

The AKTR lists Airman Certification Standards (ACS) codes for the questions you missed, for example a code in the UA.II area (airspace and requirements). Look each code up in the Remote Pilot ACS (faa.gov) and write the topic next to it. That list is your study plan.

A 14-day retake plan

Days	Focus	Goal
1	Decode your AKTR codes into topics	A written list of weak areas
2-5	Your weakest area first (for most people: sectional charts, then weather)	80%+ on topic drills
6-9	Second and third weak areas	80%+ on topic drills
10-12	Full timed 60-question practice tests	3 in a row at 80%+
13	Unseen-chart practice only (charts you have not studied)	Confidence on new images
14	Light review, sleep	Book the retest for day 15 or later

Why does the October 26, 2026 change matter for a retake?

If you failed before October 26 and retest after it, your second test will include image questions from recent sectionals that are not in the testing supplement (FAA ATCA, September 2026 Special Edition: faa.gov). Practicing only the supplement figures is no longer enough.

Worked example: turning an AKTR into a plan

Your report lists 6 ACS codes: 3 in airspace and requirements, 2 in weather, 1 in loading. One code can stand for more than one missed question, so the codes tell you where you lost points, not how many. Here airspace is half the codes. Spend days 2-5 on airspace and charts, days 6-8 on METAR/TAF, day 9 on load factor, then go to full mocks.
