Part 23 vs Part 25: Certification and Aircraft Financing
Direct answer: identify the individual aircraft's certification basis and airworthiness certificate before discussing how they affect the transaction. Part 23 and Part 25 are airworthiness standards, not loan programs or automatic operating permissions. Neither label by itself establishes a standard down payment, a maintenance budget or a universal resale market.
What is different about the certificate documents?
Obtain the actual type-certificate information, airworthiness certificate, approved manuals and applicable modifications. FAA standard airworthiness certificates lists standard certificate categories and continuing-validity considerations. Aircraft may have older certification bases or model-specific approvals, so avoid assigning a basis solely from size, appearance or a modern sales description. Confirm the candidate's status with qualified technical professionals.
What does Part 25 mean in this discussion?
The FAA transport airplane regulations resource identifies transport-airplane airworthiness regulations. It should not be read as proof that every jet is Part 25 or that a Part 25 aircraft must be flown under an airline operating certificate. Type design, pilot qualifications, intended operation and maintenance obligations are separate matters to establish for the specific acquisition.
How do special certificates change the questions?
FAA special airworthiness certificates describes categories and purposes such as experimental and restricted operations. Review the individual operating limitations before assigning a mission or commercial revenue. Do not assume a special certificate means the aircraft cannot be financed, or that technical acceptance alone makes it eligible for every proposed use. Ask the lender and insurer about the actual certification and restrictions.
What pilot and operating evidence belongs in the file?
Check the applicable 14 CFR 61.31: pilot qualification and training rules, actual aircraft documents and proposed operation with qualified instructors or operating professionals. Obtain the insurer's actual crew, training and mission terms. Legal minimums, policy conditions and a customer's requirements can differ. Certification basis should not be used as shorthand for an acceptable pilot plan or a guaranteed single-pilot insurance arrangement.
How should the financing review use this information?
Give the lender a coherent aircraft, technical, ownership and use package. Ask how certification, modifications, support, maintenance exposure and valuation affect its particular program. Obtain a specialist inspection and written costs for upcoming work. Compare financing from actual offers, preserving maintenance liquidity and a credible maturity plan rather than inventing one set of terms for all normal-category airplanes or another set for all transport-category aircraft.
