What Does It Cost Per Hour to Own a Piper Archer?

The Piper Archer (PA-28-181) is one of the most common planes people look at when they're ready to own. It has 180 horsepower, four seats, fixed gear, a fixed-pitch prop, and a Lycoming O-360 that almost any mechanic knows well. It's simple, which helps keep costs down.

But "what does an Archer cost per hour?" has no single answer. It depends mostly on how many hours you actually fly each year. Here's how to work it out.

Two kinds of costs

Like any airplane, an Archer has two buckets of cost.

Fixed costs are what you pay whether you fly or not:

• Hangar or tie-down
• Insurance
• The annual inspection
• Loan payments, or the money tied up in the plane that could be earning something elsewhere
• Subscriptions like databases and charts, plus registration and other small fees

Hourly costs are what you pay only when the engine is running:

• Fuel
• Oil
• An engine reserve, which is money you set aside every hour for the overhaul you'll eventually need
• A maintenance reserve for squawks, parts, tires, brakes, and the prop

What's typical for an Archer

These are rough ranges, so check them against your own plane, airport, and shop:

• Fuel burn: about 8.5 to 10.5 gallons per hour, depending on power setting and how you lean. Many owners plan around 9 to 10 to leave some margin.
• Engine: the Lycoming O-360-A4M. Lycoming's recommended time between overhauls (TBO) for a field-overhauled engine is 2,000 hours.
• Overhaul: commonly budgeted somewhere around $28,000 to $45,000 these days, depending on the shop and what they find. A factory engine can cost more.
• Annual inspection: often a few thousand dollars once the usual findings are fixed. An older airframe with a lot of squawks can cost well over that.

The formula

True hourly cost = (fixed costs per year ÷ hours flown per year) + hourly costs

A worked example

These are example numbers only, based on typical ranges. Your hangar, insurance, fuel price, and engine will be different, so plug in your own.

Fixed costs per year (example):

• Hangar: $4,200
• Insurance: $2,200
• Annual inspection: $3,000
• Subscriptions, fees, and everything else: $800
• Total: $10,200

Hourly costs (example):

• Fuel: 9.5 gal/hr × $6.50 = $61.75
• Oil: $2.00
• Engine reserve: $38,000 overhaul ÷ 2,000 hours = $19.00
• Maintenance reserve: $12.00
• Total: $94.75 per hour

Here's how hours flown change the picture (example data):

At 50 hours a year, each hour costs nearly twice as much as it does at 150 hours. The plane is the same; you're just spreading the fixed costs over fewer hours.

This example also leaves out any loan payment or the return your money could earn if it weren't tied up in the plane. If you finance, or if you want the full picture, add that to fixed costs. For a low-time flyer, it can be the biggest line.

Archer vs. 172

If you've read our Cessna 172 cost-per-hour breakdown, you'll notice the Archer example runs higher per hour. That's mostly from slightly higher fuel burn and a bigger engine reserve in these example numbers. In return you get more horsepower and useful load. The method is the same for both: the fixed costs and your hours drive the answer.

The reserves people skip

The engine reserve and the maintenance reserve are the two lines new owners most often leave out. At $19 an hour in this example, the engine reserve alone is roughly $1,900 a year at 100 hours. Skip it, and the hourly number looks great until the engine reaches TBO or a cylinder needs work. Setting the money aside each hour turns a surprise bill into a planned one.

Should you buy or keep renting?

Archers are a common rental, so compare your true hourly cost with the wet rate at your local school or club. At 50 hours a year, renting often wins easily. As your hours go up, owning catches up.

Run your own numbers

I built TachTime 91's free calculator to do this exact math: true hourly cost, rent vs. own, and partnership shares. It's free, with no card needed. Put in your Archer's real numbers and see where you land.

If you already own, the TachTime 91 Tracker also counts down your annual, oil changes, ELT, VOR, and ADs by tach and calendar, whichever comes first. It costs $8 a month or $79 a year per aircraft, and the first month is free with no card needed.

TachTime 91 is a planning aid. It isn't a logbook, doesn't determine airworthiness, and isn't endorsed by the FAA. Official records stay in your aircraft logbooks, and airworthiness is the owner/operator's call.
