The cheapest general aviation aircraft to operate

Fuel burn, maintenance, and real annual costs compared

February 21, 2026 · Updated May 25, 2026

Operating cost is the number that determines whether you actually fly. A bargain purchase price means little if the annual bill grounds the aircraft six months into ownership.

The aircraft in this guide share a common profile: simple fixed-gear designs, fuel-efficient four-cylinder engines, and low-cost maintenance driven by a large installed base and readily available parts. Most are two-seat trainers with a secondary life as personal aircraft. None will take you across a continent quickly, but all of them will keep you flying affordably for years.

Operating costs vary by region, maintenance history, and how many hours per year you fly. The figures below are starting points. Your actual costs depend on local fuel prices, hangar or tie-down fees, and whether you perform owner-assisted maintenance.

What determines operating cost

  • Fuel burn per hour. A four-cylinder Lycoming or Continental burning 6 to 8 gallons per hour costs roughly half as much to fuel as a six-cylinder engine burning 12 to 14. On 100 hours per year, that difference compounds quickly.

  • Engine TBO and reserve cost. Time between overhaul (TBO) varies by engine model, typically 1,800 to 2,000 hours for common training engines. Divide the overhaul cost by TBO hours to get your hourly engine reserve. A $20,000 overhaul at 2,000 hours is $10 per hour. Budget this as a real cost even if you never see it as a cash outflow until overhaul time.

  • Parts availability and mechanic familiarity. The Cessna 172 and Cherokee have been in production or on the used market for decades. Parts are abundant, cheap, and every A&P has seen dozens of them. Unusual or lightly-supported types can cost more to maintain simply because parts are scarce and mechanics charge more for unfamiliar work.

  • Annual inspection cost. Simple fixed-gear aircraft with analog panels typically run $1,000 to $2,000 for a straightforward annual. Aircraft with retractable gear, complex systems, or aging avionics cost more. Get a realistic estimate from a local mechanic before buying.

  • Insurance. Two-seat trainers are inexpensive to insure. Expect lower premiums than four-seat aircraft, especially for low-time pilots. Your logbook hours and recent flight activity affect rates significantly.

  • Hangar vs. tie-down. This is often the largest single fixed cost and has nothing to do with the aircraft itself. A $200/month tie-down versus an $800/month hangar is a $7,200 annual difference. Factor this into your total cost of ownership before comparing aircraft.

Beech 77 Skipper Piston
105 kts 412 nm 2

The Skipper is Beechcraft’s answer to the Tomahawk, sharing the same low-wing, T-tailed, bubble-canopy layout and the same economical Lycoming O-235 burning around six and a half gallons an hour. The cabin is wider than most trainers its size and the handling has a big-airplane feel owners are fond of. The thing to weigh is rarity: Beech built only about 312 before production ended in 1981, so parts hunts take longer and mechanics see them seldom. The rarity is the ownership cost to plan for: buy one with a clean logbook and a plan for sourcing the occasional hard-to-find part, and the day-to-day cost of flying it stays low.

Cessna 150 Piston
107 kts 420 nm 2

If the goal is to fly as cheaply as the certificated world allows, the 150 is where most people start and many happily stay. Roughly 23,000 were built, so parts are everywhere and every mechanic has seen dozens, which keeps the annual honest. The 100-horsepower Continental sips around five and a half gallons an hour, and airworthy examples still trade in the $20,000s. The cabin is genuinely tight at the shoulders and the climb is leisurely on a hot day, but for learning, local flying, and building hours, that is exactly the mission it was built for.

Cessna 162 Skycatcher Piston
112 kts 470 nm 2

The Skycatcher is the modern option on a list otherwise full of airplanes older than their pilots. It left the factory with a Garmin glass panel, the Continental O-200 sips under six gallons an hour, and the airframe was designed for quick inspection access, so a routine annual at a shop that knows the type stays modest. The cost lives elsewhere: Cessna abandoned the design in 2013, so airframe parts are increasingly scarce, salvage yards are often the source, and the resale market is thin. If you can accept being your own parts department, the day-to-day running cost is genuinely low.

Cessna Skyhawk 172/Cutlass Piston
124 kts 640 nm 4

The 172 earns its place on a cost list for a reason that has little to do with fuel burn: it is the most supported airplane in general aviation. More than 44,000 were built, every A&P has worked on one, parts are abundant and cheap, insurance is straightforward, and resale is the most liquid in the class. You burn around nine gallons an hour and the four-cylinder Lycoming overhauls for less than most sixes, so four seats cost you far less to keep than anything faster. It will not hurry, and the people who buy one rarely mind.

Diamond 20 Katana Piston
138 kts 525 nm 2

The DA20 is the cheapest way into modern composite flying. The slick airframe will not corrode, it cruises faster than anything else this size on roughly five and a half gallons an hour, and the bubble canopy and centre stick make it feel more sports car than trainer. Diamond two-seaters also carry a strong safety record, which insurers notice. The trade is payload and seats: it is a two-place airplane, and full fuel leaves little for baggage. For a couple or a solo pilot flying for the pleasure of it, that is no real obstacle.

Buying advice

  • High airframe time is not necessarily a problem. These simple aircraft are designed to be maintained indefinitely. Focus on engine time since last overhaul, the quality of recent annuals, and logbook continuity rather than total airframe hours.
  • Avoid aircraft with deferred maintenance. Low-cost aircraft attract buyers who defer squawks. A pre-buy inspection is just as important here as on a complex aircraft. Budget $300 to $600 for a thorough pre-buy by an independent IA.
  • Consider a leaseback or flying club. High-utilisation aircraft at flight schools accumulate engine time faster and often receive more consistent maintenance than private aircraft flying 50 hours per year. A well-maintained school aircraft can be a better buy than a low-time privately-owned one.
  • Factor in the avionics. An older aircraft with a fresh ADS-B Out installation and a working transponder is far less hassle than one requiring immediate avionics work to be legal. Check compliance before making an offer.
  • Flying more hours reduces per-hour fixed costs. Annual insurance, hangar, and inspection costs are fixed regardless of how much you fly. The more hours you put on the aircraft, the lower your effective cost per hour. If you plan to fly less than 50 hours per year, consider a flying club or rental instead.
