Prepare records, agree on inspection scope and repair approvals, and budget for an aircraft annual using quotes and maintenance history.

An annual inspection is easier to plan when the owner and shop agree on three things before the airplane arrives: the inspection scope, how discrepancies will be reported and who can authorize additional work.
This guide focuses on a typical U.S. light aircraft maintained under an annual-inspection program. Other inspection programs and exceptions exist. Confirm the applicable program from your aircraft’s records before using a generic due-date checklist.
14 CFR 91.409 sets the annual-inspection requirement and its exceptions. For an aircraft subject to that requirement, the interval is based on calendar months. An annual completed in November 2025 normally satisfies that interval through November 30, 2026; it does not establish that every other requirement remains current until then.
Confirm that the person or organization performing and approving the inspection has the appropriate authority. An A&P with inspection authorization is a common arrangement for a light-aircraft owner, but “only an individual IA can ever approve an annual” is too broad.
Provide access to the relevant airframe, engine and propeller records, the current discrepancy list and supporting information for recurring items. Ask what else the shop needs for your aircraft, modifications and inspection program.
Describe a discrepancy as an observation. “Brake pedal traveled farther than usual during taxi after landing” is more useful than “replace brakes.” Include when it happened and whether it repeated. Have a qualified person assess safety-related concerns promptly rather than saving them for the annual.
Agree on the arrival date, likely inspection duration and how the shop will communicate findings. Ask whether the estimate covers opening and closing the aircraft, routine servicing and any separate tests.
A quoted inspection price is not necessarily the final return-to-service bill. Ask for separate amounts or approval steps for:
Get current quotes for your aircraft and location. A single internet price range can hide large differences in condition, access, labor and parts availability. Agree on a spending threshold above which the shop contacts you before proceeding.
An annual does not automatically renew every inspection. Review applicable airworthiness directives, equipment inspections and component limits separately.
For example, the altimeter/static-system requirements in 91.411 and transponder requirements in 91.413 have different applicability. It is inaccurate to label both simply “IFR certification.” Ask the shop to identify what applies and what is due.
Record completed work against its own source entry and interval. Combining shop visits can be convenient, but the records still need to distinguish the work performed.
Use the aircraft’s actual maintenance history and current quotes to estimate a reserve. Separate predictable inspection expenses from unexpected repairs and major component work.
As an illustration, setting aside $3,600 over a year requires $300 per month. That is a budgeting example, not a prediction of an annual’s cost. If you recover the amount through a club hourly charge, check how lower-than-expected utilization affects the fund.
The ownership cost calculator lets you change those assumptions. Keep some liquidity for work that arrives before the reserve has accumulated.
Before returning the aircraft to service, review the inspection outcome, completed maintenance entries and any unresolved discrepancies with the responsible maintenance provider. Check that the records support the required approvals and update your tracking dates from those records.
If the aircraft is not approved for return to service, resolve the applicable requirements before flying. A special flight permit, when appropriate and issued, has its own conditions; an appointment at another shop is not permission to depart.
Aloft360’s owner workspace can keep inspection reminders and reported discrepancies together. Its role is to organize the follow-up, while authorized maintenance personnel and the aircraft records establish the inspection result.
