Prices for a 100 hour inspection typically depend on shop rates, aircraft type, and the scope of the inspection. This guide presents cost ranges in USD and highlights the main drivers behind pricing. A precise estimate should account for labor hours, parts, and possible additional work.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Inspection Labor | $1,200 | $1,850 | $2,900 | Typical 6–10 hours at $150–$250/hr |
| Parts & Consumables | $100 | $450 | $1,000 | Filters, fluids, gaskets, hardware |
| Aircraft Type Surcharge | $0 | $200 | $800 | Complex systems may add time |
| Shop Fees & Overhead | $150 | $350 | $800 | Facilities, admin, tooling |
| Permits & Documentation | $0 | $120 | $300 | Record updates, sign-offs |
| Taxes | $0 | $180 | $320 | Varies by state |
Overview Of Costs
The cost for a 100 hour inspection ranges roughly from $1,650 to $5,420 in typical U.S. shops, with most projects landing between $2,000 and $3,500 when no surprises arise. The main drivers are labor hours, parts needs, and any required minor repairs discovered during the inspection. Assumptions: region, specs, labor hours.
Cost Breakdown
Table shows the primary cost categories and ranges. Totals assume standard airframe and powerplant configurations without major repairs. The per-hour labor rate commonly falls in the $150–$250 range, depending on shop reputation, location, and technician certifications.
| Category | Low | Average | High | Notes |
|---|---|---|---|---|
| Labor | $1,200 | $1,850 | $2,900 | Typically 6–10 hours |
| Parts & Fluids | $100 | $450 | $1,000 | O-rings, filters, oil, hydraulic fluid |
| Overhead | $150 | $350 | $800 | Facilities, admin, tooling usage |
| Permits & Documentation | $0 | $120 | $300 | Sign-offs and logbook updates |
| Taxes | $0 | $180 | $320 | State and local taxes |
Factors That Affect Price
Key price drivers include aircraft complexity and engine type. A straightforward single-engine plane often trends toward the lower end, while multiengine or pressurized airframes push both labor time and parts costs up. Additional factors include data-formula=labor_hours×hourly_rate> shop location, technician qualifications, and the availability of used or refurbished components. Regional demand can also impact monthly pricing trends.
Ways To Save
Save by planning for related maintenance at the same time. Bundling the 100 hour inspection with fluids, filter changes, and minor corrective items can reduce per-project overhead and avoid repeat labor. Some shops offer fixed-price packages for standard airframes, which helps budget predictably. Request detailed scope notes to avoid paying for unnecessary items and compare quotes from at least three shops.
Regional Price Differences
Prices vary by region due to labor markets and taxes. In the Northeast, total costs can be 5–12% higher than the national average. The Midwest tends to align with the average, while the South may be 3–8% lower in some cases. Rural shops can charge less for labor but may add travel or delivery fees. Assumptions: 100-hour inspection on common general aviation platforms.
Labor & Installation Time
Labor hours typically range from 6 to 10 hours for standard airframes. Heavier aircraft, turbine engines, or airplanes with complex avionics can extend to 12–15 hours or more. The rate per hour commonly spans $140–$260. For a 100-hour inspection, total labor may exceed baseline when extra items are found.

Real-World Pricing Examples
Three scenario cards illustrate typical outcomes.
- Basic — single-engine, no major issues; 7 hours labor at $170/hr; parts $250; overhead $200; total $1,900. Scenario assumes no surprises. Assumptions: region, specs, labor hours.
- Mid-Range — single-engine with minor items; 9 hours labor at $190/hr; parts $550; overhead $300; taxes $150; total $3,100.
- Premium — multiengine or turbine with extra systems checks; 12 hours labor at $220/hr; parts $900; overhead $500; permits $300; total $5,420.
Price At A Glance
Typical project range: $1,900 to $5,400. Mid-range expectations commonly fall between $2,600 and $3,600 for many general aviation aircraft. The exact total depends on labor time and parts required, plus any incidental repairs identified during the inspection. Proactive scheduling and bundled services can help stabilize the budget.
