Light Sport Aircraft Buyer's Guide: Legacy LSA, New Part 22 Aircraft and Certified Options

If you are buying your first light-sport airplane, the choice is no longer one category with fixed limits. This guide sorts the options into the three kinds of aircraft you'll see for sale, explains how each is inspected and maintained, and shows what ownership and financing look like.

What counts as a light sport aircraft in 2026?

Before MOSAIC, "light-sport aircraft" was a single definition: 1,320 lb maximum takeoff weight (1,430 lb on floats), two seats, a clean stall speed of 45 KCAS or less, 120 KCAS maximum level speed, one piston engine, fixed gear and a fixed or ground-adjustable propeller. Those are now the former rules. MOSAIC split the idea in two:

• What a sport pilot may fly (since October 22, 2025): any non-pressurized airplane with up to four seats and a clean stall speed (VS1) of 59 KCAS or less at maximum takeoff weight, in any airworthiness category, with one passenger.
• What can be certificated as a light-sport category aircraft (since July 24, 2026): new designs meeting 14 CFR Part 22, with no weight cap, up to four seats, a landing-configuration stall speed (VS0) of 61 KCAS or less and VH up to 250 KCAS.

For a first-time buyer, that produces three shopping lanes. The full before-and-after rule comparison, and what it means for values and lender appetite, is in our MOSAIC light sport aircraft financing guide. This page focuses on how the aircraft themselves differ.

How do S-LSA, E-LSA, Part 22 and certified airplanes compare?

Sources: FAA MOSAIC fact sheet, 14 CFR Part 22, Gleim, July 29, 2026, FLYING Finance rates. Rates are starting points for strong credit, not quotes.

Can an older LSA be upgraded to the new MOSAIC limits?

Not by the owner. A legacy light-sport aircraft can exceed its original limits only if it complies with the current MOSAIC requirements, the manufacturer issues a new statement of compliance based on the new consensus standards, and the aircraft gets a new special airworthiness certificate. If a seller advertises "MOSAIC gross-weight potential", ask for the manufacturer's published program. Without one, value the airplane at its current certificated limits.

That matters most for payload. A 1,320 lb two-seater carries two adults, fuel and a little baggage, with small margins. If you need more, a certified airplane a sport pilot can fly, or a new Part 22 design, may fit better than an older LSA.

How do maintenance and inspections differ by category?

S-LSA and new light-sport category aircraft

Maintenance follows the manufacturer's maintenance and inspection instructions. An A&P mechanic or a light-sport repairman with a maintenance rating performs the annual condition inspection, plus 100-hour inspections if the airplane is rented or used for instruction. An owner with at least a sport pilot certificate may do preventive maintenance. Major repairs must be authorized by the manufacturer or a person acceptable to the FAA, according to the FAA's MOSAIC maintenance FAQ.

The same FAQ says owners are not legally required to comply with manufacturer safety directives, though the FAA strongly encourages it (SAIB 2026-06), and FAA Airworthiness Directives remain mandatory. As a buyer, treat open safety directives as a price and insurability issue either way.

E-LSA

Experimental rules give the owner more freedom. Anyone may perform maintenance, and an owner who completes the light-sport repairman inspection-rating course can sign off the annual condition inspection on their own aircraft. MOSAIC broadened the aircraft that rating can cover. The trade-off is that an E-LSA can't be used for paid instruction, which shrinks the resale market to private owners. Course requirements have changed under MOSAIC, so confirm current details with the FAA before you rely on doing your own inspections.

Standard-category airplanes flown by sport pilots

Nothing changes. AOPA notes that certified airplanes such as the Cessna 172 "must be maintained according to Part 43". That means A&P mechanics, an annual inspection signed by an IA, and full AD compliance. A light-sport repairman rating does not cover these airplanes.

Calendar items on Rotax-powered LSAs

Most legacy LSAs use a Rotax 912-series engine. Rotax specifies time between overhauls in hours and years, and calls for periodic replacement of rubber hoses and other rubber parts, commonly every five years. Because S-LSA maintenance follows the manufacturer's instructions, treat those calendar items as due. An airplane that flies little can still owe a large calendar-driven bill. The SportStar and Tecnam P2008 guides cover the Rotax details model by model.

Manufacturer support

Several LSA brands have changed hands or left the U.S. market since 2005. If the manufacturer is gone, parts and major-repair approvals get harder, which affects insurance, financing and resale. Before you make an offer, ask the seller who currently supports the type in the U.S. and whether service bulletins are still being issued.

How much does a light sport aircraft cost to buy?

There is no reliable single price range for "an LSA", because the category spans 20-year-old two-seaters and new four-seat designs. Some reference points from Controller.com listings in September 2026 (asking prices, which are not sale prices):

• Tecnam P2008 (U.S. S-LSA): $160,000 for a 2021 with about 1,100 hours, and $224,900 for a 2015 with about 100 hours.
• Diamond DA20-A1 Katana (certified, may be sport-pilot eligible): about $88,000–$93,000.
• Diamond DA20-C1 Eclipse, 2008–2012: roughly $180,000–$260,000.

Older LSAs from smaller or orphaned brands can list for much less, and they often carry the parts-support risk described above. Pull sold comparables from a broker or a valuation service before you offer. Your lender's appraisal will use them anyway.

What does a light sport aircraft cost to own? A worked budget

The example below assumes a $120,000 Rotax-powered S-LSA flown 75 hours a year, financed with 15% down over 20 years at 7.75%. The fuel line uses verified numbers. Every other line is an assumption, so replace it with your own quotes.

Two things move this budget the most: the loan payment and hours flown. Flying fewer hours raises the all-in hourly cost quickly, because insurance, hangar and the loan are fixed. Many Rotax engines can also run on premium unleaded auto fuel where the aircraft's documents allow it, which can lower fuel cost. Check the POH and the Rotax operator's manual before you plan on it.

How is financing different for a light sport aircraft?

Lenders do finance light-sport aircraft, but they look at a few things differently from a certified trainer:

• Rate: FLYING Finance's September 2026 starting rates are 7.71% for MOSAIC light-sport, 7.01% for certified piston and 7.78% for experimental or kit aircraft. Piston loans generally run from about 7% to 10% depending on credit, loan size and down payment.
• Loan-to-value: FLYING Finance lists up to 85% for S-LSA. AOPA's minimum down payment is 15% for post-1960 singles.
• Term: AOPA's lenders offer 20-year single-engine terms only on loans of $75,000 or more. A smaller LSA loan may be limited to 10–15 years.
• Collateral questions: manufacturer support, comparable sales and, for experimental aircraft, build documentation.

Loan amount $102,000. Principal and interest only; excludes insurance, taxes and fees. Illustrative, not a quote.

The category-by-category financing comparison, with the same loan priced at each starting rate, is in the MOSAIC financing guide. For experimental and kit aircraft, see financing experimental aircraft.

Pre-purchase checklist for a first light-sport airplane

1. Read the airworthiness certificate and operating limitations. Confirm whether it is S-LSA, E-LSA, a new light-sport category aircraft or standard category. The category drives maintenance, rental use, rate and resale.
2. For S-LSA, get the statement of compliance, POH and current maintenance manual revision. Missing manufacturer documents are a red flag for lenders and insurers.
3. Check safety directive, service bulletin and AD status. List anything open and price it into your offer.
4. Check the engine calendar, not just the hours. On a Rotax, note the year of manufacture, the last rubber-parts replacement and the TBO in both hours and years.
5. For certified airplanes, verify sport-pilot eligibility on paper. VS1 of 59 KCAS or less at max takeoff weight, from the airplane's own POH or AFM.
6. Confirm U.S. manufacturer support. Find out who supplies parts and who approves major repairs.
7. Get an insurance quote and a pre-buy inspection by a mechanic who knows the type. See the pre-buy inspection checklist.
8. Confirm registration. FAA registration is valid for seven years and costs $5, and the registration guide covers the transfer paperwork.
