The cheapest general aviation aircraft to operate
Fuel burn, maintenance, and real annual costs compared
Operating cost is the number that decides whether you actually fly. A low purchase price means little if the annual bill grounds the airplane six months into ownership.
This guide covers eight of the cheapest certificated aircraft to operate, chosen for low fuel burn, simple maintenance, and running costs you can sustain at the modest hours most owners log. The emphasis is on what it takes to keep one flying year after year, not what it costs to buy.
What these eight cover
Every airplane here shares one shape: a fixed-gear airframe, a fuel-efficient four-cylinder engine, and modest speed and range. Most are two-seat trainers that found a second life as personal airplanes; two carry four seats. None will cross a continent quickly, and none is meant to.
Where they part company is support. Some of these types have tens of thousands built and a parts bin in every hangar; others are rare or out of production, and keeping one flying means hunting parts a common type would never make you chase. That axis, more than fuel burn, is what separates the easy ownership from the patient kind. The next section sorts them by the flying you actually do.
Which one fits how you fly
- If you are learning or building hours on the tightest budget: the Cessna 150 is the certificated baseline every other airplane here is measured against.
- If you need four seats and want the lowest cost to keep them: the Cessna 172 has the deepest parts and mechanic network in general aviation, which is what holds its running cost down.
- If you want four-seat economy but prefer a low wing: the Piper Cherokee is the low-wing answer, with the same fixed-gear simplicity and a deep PA-28 fleet behind it.
- If you want some sport in the bargain: the Grumman AA-1 handles livelier than its running costs suggest, as long as you respect a less forgiving wing.
- If the hourly cost is the single deciding factor: the Piper Tomahawk sits at the bottom of this list, once you account for its airworthiness directive and the spin training it asks for.
- If you want a modern glass panel out of the box: the Cessna 162 Skycatcher is the newest design here, traded against a parts supply that dried up after Cessna left the market.
- If you want a modern composite airframe that will not corrode: the Diamond DA20 is the cheapest way into one, for a pilot flying mostly for the pleasure of it.
- If cabin comfort matters more than rarity: the Beechcraft Skipper is wider than most trainers its size with a big-airplane feel, if you can plan around harder parts hunts.

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.
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.
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.
The little Grumman is the budget two-seater for the pilot who wants some sport in the bargain. The bonded, rivet-free airframe is slick enough to show a clean turn of speed on the same modest Lycoming O-235 that plods along in a 150, the sliding canopy gives a fighter-like view, and the engine’s long 2,400-hour TBO keeps the per-hour overhaul reserve low. The catch is the wing: it stalls higher and sinks faster than a Cessna or Piper trainer, so it wants honest speed control and proper transition training. Give it that respect, and the payoff is handling far livelier than its running costs suggest.
The Cherokee is the low-wing answer for buyers who want the 172’s running costs in a different package. The carbureted Lycoming O-320 and fixed gear keep maintenance about as simple as certificated flying gets, insurance runs low, and the deep PA-28 fleet means parts and mechanics are easy to find. This is the short-fuselage 140: four seats on paper, but realistically two adults, a couple of small passengers and bags. The blunt Hershey-bar wing sheds energy quickly when the power comes off, so fly the numbers on approach.

Buying advice
The cheapest airplane to buy and the cheapest to operate are rarely the same one. What you spend each year is set before you take delivery, by a handful of numbers worth running first. Treat the figures below as starting points: your real cost moves with local fuel prices, where you park the airplane, how many hours you fly, and how much of the maintenance you do yourself.
Start with fuel and the engine. A four-cylinder Lycoming or Continental burning 6 to 8 gallons an hour costs roughly half as much to feed as a six burning 12 to 14, and over 100 hours a year that gap compounds. Add the overhaul reserve you should set aside whether or not you ever write the cheque: common training engines reach time between overhaul (TBO) at 1,800 to 2,000 hours, so a $20,000 overhaul works out to about $10 an hour. Budget it as a real cost, not a someday cost.
Then the standing bills. A simple fixed-gear airplane with an analog panel usually runs $1,000 to $2,000 for a straightforward annual; retractable gear, complex systems, and aging avionics push that up. Parts and mechanic familiarity move the number as much as the labour rate, which is the axis the picks divide on: a deep fleet keeps an airplane cheap because parts are abundant and every A&P has worked on one, while a scarce type costs more simply because parts are hard to find and unfamiliar work bills slower. Two-seat trainers insure cheaply, lower than four-seaters, though your hours and recent activity move the rate. And the largest fixed cost often has nothing to do with the airplane: a $200-a-month tie-down against an $800-a-month hangar is a $7,200 annual swing. Settle where you will keep it before you compare airplanes.
A few habits separate a good buy from an expensive one:
- Judge the engine, not the airframe. These simple designs are built to be maintained indefinitely, so high total airframe time is rarely the problem. Look at hours since overhaul, the quality of recent annuals, and logbook continuity instead.
- Pay for the pre-buy. Low-cost airplanes attract owners who defer squawks, so an independent pre-buy by an IA matters as much here as on a complex aircraft. Budget $300 to $600 for a thorough one.
- Check the avionics are already legal. An airplane with a working ADS-B Out install and transponder is far less hassle than one needing immediate avionics work to fly controlled airspace. Confirm compliance before you offer.
- Consider a club or leaseback. A well-maintained, high-utilisation school airplane often gets more consistent care than a private one flown 50 hours a year, and can be the better buy. If you will fly less than 50 hours a year, a club or rental may beat ownership outright.
- Fly it enough. Insurance, hangar, and annual are fixed whatever you fly, so the more hours you put on the airplane, the lower the cost of each one.
The bottom line
A trainer-class single is the right airplane when low running cost outweighs speed, range, and seats. Simple systems and a four-cylinder engine keep the yearly bill within reach of a modest budget, which is the whole point of buying one. What they will not do is travel far or fast with a full cabin. If your mission grows past two people or a few hundred miles, this is the wrong list. If it does not, any airplane here will keep you flying for the price of staying current, and the right one turns on seats, support, and how much the airframe asks of your hands.
