How much does an annual inspection cost?
Updated · Wingman AeroCare, KFNL
Short answer: The inspection itself is mostly labor: typically about 12-20 hours for a simple fixed-gear single like a Cessna 172 and 20-35+ hours for complex or high-performance singles like a Bonanza or Cirrus SR22, multiplied by the shop's hourly rate. That usually puts inspection labor somewhere around $1,500 to $5,000 or more. The total invoice is driven by what the inspection finds, and repairs often equal or exceed the inspection cost itself.
What makes up the cost of an annual?
An annual invoice has two parts:
- The inspection. Opening the aircraft, inspecting it to at least the scope of 14 CFR Part 43 Appendix D, reviewing records and ADs, running the engine, closing it up, and making the logbook entries. This is fairly predictable for a given aircraft type.
- The discrepancies. Anything found that needs repair, replacement, or AD compliance. This is the unpredictable part: one airplane needs a set of brake linings, the next needs a cylinder.
Shops either charge a flat rate for the inspection portion or bill actual hours. Both are common. Either way, the repair portion is almost always billed as time and materials.
Typical inspection labor by aircraft type
These are rough industry ranges for the inspection portion only. They vary widely with the aircraft's condition, equipment, how well records are organized, and whether it has been inspected at the same shop before.
| Aircraft class | Examples | Typical inspection labor |
|---|---|---|
| Fixed-gear 4-cylinder single | Cessna 172, Piper PA-28 | About 12-20 hours |
| Larger fixed-gear single | Cessna 182, Piper PA-32 fixed gear | About 15-25 hours |
| High-performance or retractable single | Cirrus SR20/SR22/SR22T, Bonanza, PA-32R, PA-46 piston | About 20-35+ hours |
| Light piston twin | Beechcraft Baron | About 30-50+ hours |
Shop labor rates in the U.S. commonly fall somewhere between about $110 and $200 per hour depending on region and specialization. Multiply the hours by the rate and you have a reasonable inspection estimate.
What drives the total bill up?
The biggest swings come from findings, not the inspection itself:
- Engine findings: low compression, a burned exhaust valve, metal in the filter, or cam and lifter problems. A single cylinder replacement can add several thousand dollars on its own.
- AD compliance: recurring ADs (some require repeated inspections every annual or every 100 hours) and new ADs issued since the last inspection.
- Corrosion: especially in older airframes or aircraft stored outdoors.
- Deferred maintenance: items a previous owner or shop pushed down the road.
- Records problems: missing Form 337s, unclear AD status, or equipment lists that do not match the aircraft. Research time is labor.
- Age and use: aircraft that fly rarely tend to develop more problems (corroded cylinders, dried seals) than aircraft that fly regularly.
A reasonable planning rule for owners: budget the inspection, then budget at least that much again for repairs, more for an older or unfamiliar aircraft. A first annual at a new shop is often the most expensive because the shop is establishing a baseline.
How can I keep the cost down?
- Fly regularly. Engines and seals do better with use.
- Fix known squawks between annuals so they are not all discovered at once.
- Keep organized records with a current AD status list.
- Ask for an estimate with each finding itemized so you can decide what is required now and what can wait.
- Consider whether some preventive maintenance is something you can legally do yourself under Part 43 Appendix A. See what maintenance an owner can do.
Avoid choosing a shop solely on the lowest flat-rate quote. A thorough annual that finds a problem early is cheaper than an engine failure or a missed AD discovered at resale.
How Wingman handles it
At Wingman AeroCare, labor is billed hourly against an estimate you approve first, and we will give you an estimate for your specific aircraft on request through our contact page. For an inspection, we collect a deposit based on estimated hours up front and settle it against actual hours, so you pay for the time the work actually takes. Every finding is itemized on an online estimate with photos and video and labeled Airworthy, Recommended, or Optional; you approve or decline each item, and nothing beyond the approved scope is done without your approval.
