2.1 Eligibility, Training, and Knowledge-Test Authorization

The Private Pilot ACS (PA.I.A) does not ask whether flying is fun. It asks whether you can keep three clocks, three ages, and three endorsements from collapsing into one vague idea of being “signed off.” A 16-year-old who just passed the PAR is not a private pilot. A 40-hour logbook without the nested 61.109(a) items is not a complete logbook. And the instructor stamp that let you sit the knowledge test is not the stamp that lets a designated examiner open IACRA for the practical test.

Who may be issued the certificate — 14 CFR 61.103

Section 61.103 is the gate for the certificate, not for the written test. For an airplane rating, the applicant must:

• Be at least 17 years of age when the private pilot certificate is issued (16 only if the rating sought is glider or balloon).
• Be able to read, speak, write, and understand the English language. If a medical reason blocks one of those skills, the Administrator may add operating limitations instead of refusing the certificate.
• Receive a logbook endorsement from an authorized instructor who conducted the 61.105 knowledge training or reviewed the applicant’s home study and certified that the person is prepared for the knowledge test.
• Pass the required knowledge test on the 61.105(b) areas.
• Receive flight training and a logbook endorsement covering the 61.107 areas of operation, certifying preparedness for the practical test.
• Meet the aeronautical experience that applies to the rating — for airplane single-engine land, that is 61.109(a) — before applying for the practical test.
• Pass the practical test.
• Hold a U.S. student, sport, or recreational pilot certificate.

Those bullets are independent. English, endorsements, the knowledge test, the experience table, and the practical test are not interchangeable. Missing any one of them keeps the certificate in the examiner’s printer.

Age 15, 16, and 17 are three different privileges

The Airman Knowledge Testing Matrix dated October 22, 2025 lists PAR (Private Pilot Airplane) as a 60-question, 2.0-hour test with a 70 percent passing score and a minimum testing age of 15. That matrix age is a testing-center rule. It is not 61.103.

A 15-year-old with a 61.35 endorsement may take PAR. The Airman Knowledge Test Report (AKTR) is then good for 24 calendar months under 61.39(a)(1)(i). If that applicant turns 17 while the AKTR is still valid, the same report can support a practical test. If the applicant is still 16 on checkride day, 61.39(a)(5) stops the test: the applicant must meet the prescribed age for issuance.

The classic PAR trap is collapsing those ages. “You must be 17 to take the written” is false. “Passing the written at 15 makes you a private pilot” is also false.

Knowledge-test authorization — 61.35 (and part 141)

Section 61.35 tells the testing center what to accept before the clock starts. An applicant must have:

1. An endorsement, if required, from an authorized instructor certifying that the applicant completed the appropriate ground training or a home-study course and is prepared for the knowledge test.
2. Proper identification with a photograph, a signature, and a date of birth showing the applicant meets — or will meet before the AKTR expires — the age requirement for the certificate sought.
3. A residential address if the mailing address is a post-office box.

A part 141 graduate does not invent a fourth set of knowledge areas. The approved school’s graduation certificate (or the authorization the FAA testing matrix lists for that course) is the usual substitute for a stand-alone 61.35 instructor endorsement. Either way, someone accountable has certified that the aeronautical-knowledge training happened and that the applicant is ready. Showing up with only a student-pilot certificate and a logbook full of dual is not authorization.

The 61.35 endorsement answers one question: may this person sit PAR? It does not say the person has 40 hours, is current for solo, or is ready for the practical test.

Aeronautical experience — 61.109(a) ASEL

For airplane single-engine land under part 61, log at least 40 hours of flight time, including at least 20 hours of flight training from an authorized instructor and 10 hours of solo flight training in the 61.107(b)(1) areas of operation. Inside those totals, the training must include at least:

Those nested numbers do not add to 40. The 3-hour night block lives inside the 20 dual hours. The 150-NM solo lives inside the 10 solo hours. An applicant with 42 total hours who never flew a night cross-country over 100 NM, or whose long solo had only two full-stop points, is not eligible.

Calendar months are not 60-day windows. If the practical test is in August, the 3 hours of prep must have been flown in June, July, or August — not “sometime in the last 60 days” if that 60-day count started in late May.

Part 141 or part 142 approved courses may reduce the total time (61.109(k)(3) allows 35 hours after an approved part 142 private course). They do not erase the idea of dual, solo, night, and cross-country quality. Know the part 61 table cold; that is what PAR items are written against.

Student-pilot flying is a different certificate — 61.87, 61.89, 61.93

Until the private certificate is issued, airplane flying is student-pilot flying. High-level, keep three rules separate:

• 61.87 (authorization to solo). A student may not solo without an instructor endorsement for the specific make and model, given after the required pre-solo knowledge demonstration and flight training. The solo endorsement is good for 90 days; after that it must be renewed. 61.87 is permission to leave the ground alone. It is not permission to leave the practice area.
• 61.89 (the leash). A student acting as PIC may not carry a passenger, carry property for compensation or hire, fly for compensation or hire, fly in furtherance of a business, make an international flight (with a narrow Alaska–Whitehorse training exception), fly with less than 3 statute miles day / 5 statute miles night visibility, fly without visual reference to the surface, or ignore limitations the instructor wrote in the logbook.
• 61.93 (solo cross-country). Flights more than 25 nautical miles from the origin airport need additional XC training and endorsements — a make-and-model XC endorsement plus, for each XC, an instructor endorsement for that flight’s conditions, airports, and route.

A parent in the right seat is a passenger. 61.89 does not care that the parent is a rated pilot, a CFI, or “just along for the landing.” No passengers means no passengers.

Knowledge-test endorsement versus practical-test endorsement

Two instructor signatures are not interchangeable.

Knowledge test (61.35 / 61.103(d)). Ground training or reviewed home study; instructor certifies the applicant is prepared for PAR (or a part 141 graduation document does that job). No 2-calendar-month recency clock attaches to that endorsement.

Practical test (61.39(a)(6) and 61.103(f)). The instructor must certify that the applicant:

1. Received and logged training time within 2 calendar months preceding the month of application in preparation for the practical test,
2. Is prepared for the required practical test, and
3. Has demonstrated satisfactory knowledge of the subject areas deficient on the AKTR.

An applicant who passed PAR eight months ago still needs that deficiency review before the checkride, even if the written score was 92 percent and only two ACS codes printed. The examiner is entitled to see that the weak knowledge areas were retrained, not merely that a written test once happened.

61.39 also requires a still-valid knowledge test (24 calendar months for PAR), the required training and experience, at least a third-class medical if a medical is required, the age for issuance, and a completed application. Miss the 2-calendar-month prep flight and the checkride does not start, regardless of total time.

The useful mental model is a pipeline: 61.35 opens the testing center, 61.87/61.89/61.93 govern student solo while you build 61.109, and 61.39 plus 61.103(f) open the examiner’s airplane. Each document answers a different yes/no question. PAR items are written to punish anyone who treats them as one generic “instructor signoff.”
