Cessna 150 and 152 Annual vs 100-Hour Inspections: U.S. Record Review
For a Cessna 150 or 152 operated under the usual U.S. Part 91 inspection provisions, an annual inspection and a 100-hour inspection answer different scheduling requirements. Aircraft use, the applicable inspection program and the signed record determine which requirement matters. A seller's phrase "fresh annual" does not describe everything a buyer needs to review.
Calendar time and operating time
14 CFR 91.409 generally requires an annual within the preceding 12 calendar months. Its 100-hour provision addresses carrying persons other than crew for hire and giving flight instruction for hire in an aircraft the instructor provides. Paragraph (c) contains exceptions, including specified alternative inspection arrangements. These are U.S. rules; this article does not assign that schedule to a foreign-registered Reims aircraft.
An annual can satisfy the inspection described in the 100-hour provision. A 100-hour inspection does not replace an annual unless an appropriately authorized person performs it and records it as an annual. The limited en-route allowance in paragraph (b) is tied to reaching an inspection location and counts against the next interval; it is not a general scheduling cushion.
Read the entry before discussing the invoice
Begin with the inspection type, completion date, aircraft identity and approval entry. Then reconcile the entry with the aircraft's recorded utilization and inspection program. The maintenance-record rule treats inspection status separately from applicable AD status. One date on an invoice therefore cannot answer both questions.
For a prospective purchase, ask for the inspection entry and associated discrepancy information before arranging travel. Put unresolved questions in the prebuy scope: what will be examined, what access is available, and which records the reviewer will receive. This is a practical way to compare two advertised aircraft without treating a recent inspection as a warranty of their condition.
Annual inspection and prebuy serve different decisions
A prebuy inquiry is organized around the purchase and the buyer's concerns. The annual entry belongs to an applicable inspection and return-to-service process. Agreeing to one does not describe the scope of the other. An aircraft can also have a long repair history that deserves attention even when its most recent inspection entry is easy to locate.
Use the maintenance-publication guide to identify the relevant manuals, and logbook research to connect dated work with the installed equipment. Record the regulatory section and the observed publication date alongside your questions so a later reviewer can reproduce the reasoning.
The ELT has inspection and battery evidence
The ELT records guide separates the transmitter’s inspection entry from its battery date and equipment identity. If those checks are organized alongside the annual, retain their individual record locators so a later owner can determine what was examined and which unit was installed.
Use the maintenance-entry guide for ordinary work descriptions, while preserving the distinct requirements for inspection entries. A repair performed during an inspection and the inspection’s own result should remain understandable as separate parts of the file.
An annual record in a purchase file
The prebuy-versus-annual guide distinguishes the inspection entry from the buyer’s broader questions about configuration, repair history and documentary gaps. Read the actual entry and subsequent work rather than relying on an advertisement’s inspection date. During ownership, carry the supported status into an aircraft-specific planning record, preserving the source and basis of each next-action question. A planning list does not replace the inspection record or turn unrelated recommendations into the same requirement.
