Eligibility Requirements: Flight Instructor

Research Notes — § 61.183 Eligibility Requirements: Flight Instructor

Governing Advisory Circular — AC 61-65K

AC 61-65K — Certification: Pilots and Flight and Ground Instructors (current version). Why it matters at the checkride: it contains the exact endorsement language — word-for-word — required for three separate endorsements under § 61.183: the FOI knowledge test endorsement (paragraph (d)); the flight training endorsement certifying completion of § 61.187(b) areas of operation (paragraph (g)); and the spin training endorsement (paragraph (i)(1)). Examiners verify these endorsements before accepting a practical test application. A paraphrased or incomplete endorsement gives a DPE grounds to turn you away at the door. Use AC 61-65K.

Stall and Spin Awareness Training — AC 61-67C (Change 2)

AC 61-67C with Change 2 — Stall and Spin Awareness Training. This AC is load-bearing for the spin endorsement requirement in § 61.183(i) because the regulation alone does not tell you which aircraft are suitable. The AC clarifies: (1) spin training must be accomplished in an aircraft certificated for spins — not merely for incipient spins, which is the limit for many common trainers like the Cessna 172; (2) only CFI-airplane and CFI-glider applicants must demonstrate instructional proficiency in full spin entry and recovery; (3) the DPE may accept the endorsement as satisfactory evidence of proficiency at a first-attempt practical test, but must test spins in the aircraft at a retest for spin deficiencies. If your endorsement was signed after training in an aircraft not approved for intentional spins, the endorsement does not satisfy the regulation regardless of what it says.

AIM Cross-Reference

AIM Chapter 8 — Medical Facts for Pilots: Referenced through the FOI knowledge areas in § 61.185(a)(1). The FOI curriculum covers human factors in flight instruction — physiological and psychological factors that affect how students learn under stress, in novel environments, and under time pressure. AIM Chapter 8 is the regulatory grounding for these topics. The Aviation Instructor's Handbook (FAA-H-8083-9) is the primary training reference for the § 61.183(d) endorsement, covering learning theory, communication, lesson planning, critique, and evaluation. Why it matters for training quality: instructors who understand the science of how students learn are meaningfully better at developing pilot judgment — not just checking maneuver boxes.

FOI Knowledge Test — Endorsement Requirement Change (September 2024)

Effective September 1, 2024, the FAA reinstated a logbook endorsement requirement for the FOI knowledge test. What changed: an applicant must now receive an endorsement from an authorized ground or flight instructor certifying that the applicant completed ground training and is prepared for the FOI knowledge test. Walk-in testing without an instructor endorsement is no longer accepted. Why the FAA reinstated this: an endorsement requirement means a credentialed instructor has actually evaluated whether the applicant understands instructional theory — not just whether they passed an online ground school module. The exemption pathways are narrow: current CFI or ground instructor certificate under Part 61, or a state teacher's certificate authorizing teaching at or above 7th-grade level. Corporate trainers, flight school ground staff without a CFI certificate, and similar roles do not qualify. Source: Flight Training Central — FOI Endorsement Change

Related Regulations

• § 61.185 — Aeronautical Knowledge (Flight Instructor): Enumerates the FOI areas (§ 61.185(a)(1)) and the aeronautical knowledge areas for the specific rating sought (§ 61.185(a)(2) and (a)(3)) that underlie the two required CFI knowledge tests. A CFI candidate must pass both: the FOI exam and the aeronautical knowledge exam for their rating (FOI + FIA for airplane). Passing one does not satisfy the other.
• § 61.187 — Flight Proficiency (Flight Instructor): Companion to § 61.183(g). Lists the areas of operation that must be trained and logged before the § 61.183(g) endorsement can be signed. The practical test can range across any area in § 61.187(b) — gaps in training will surface at the checkride.
• § 61.195(k) — Prohibition on Training Initial CFI Applicants: Added in 2023 (88 FR 33248). A newly certificated CFI must hold the certificate for 24 months and train a minimum number of applicants before supervising another CFI candidate. This affects who can legally sign the § 61.183(d) and (g) endorsements for a first-time CFI applicant — not every instructor is eligible regardless of their experience.
• § 61.197 — Flight Instructor Certificate Renewal: Holding an existing CFI or ground instructor certificate creates an exemption from the FOI knowledge test under § 61.183(e) — the assumption is that an active instructor already operates at that standard. This is a common confusion point for CFI candidates adding a second rating.

NTSB Precedent

NTSB Order No. EA-5730 and related administrative law judge decisions address FAA certificate action cases where flight instructors were cited for issuing § 61.183(i) spin endorsements without conducting actual spin flight training in a certificated aircraft. The NTSB has consistently upheld FAA enforcement actions in these cases. What this precedent means for you as a CFI candidate: the spin endorsement must truthfully reflect training that was actually accomplished in an aircraft certificated for intentional spins. An instructor who signs the endorsement after ground discussion only — believing the regulation only requires proficiency to be demonstrated at the checkride — is exposing both their own certificate and their student's endorsement to legal challenge. There is no shortcut here.
