For those unfamiliar with planes, you can buy a used ultralite plane for under $10,000 in working condition. Something that has been proven to fly reliably.

Or you could buy a certified cessna 150 for $15k. Much less likely to kill you or have an engine failure.

Anyway this isn't really anything new. You can already build your own plane from plans, and the plans only cost about $100 (a very small portion of the cost of building):

In fairness it should be mentioned that the first Cessna 150 was made in 1951 and the last was built in the mid-70s so we are not talking about "late model" aircraft by any stretch of the imagination.
Re:First Open Source Airplane Could Cost Just $15,000 by cpncrunch on Tuesday July 30, 2013 @05:18PM (#6130129)
Agreed, but a 50 year old 150 is a lot safer than most homebuilts (especially if the engine is homebuilt too!)

In theory it may be possible to build a safe aircraft for $15k, but it really depends a lot on the builder.

Re:First Open Source Airplane Could Cost Just $15,000 by glabifrons on Tuesday July 30, 2013 @06:25PM (#6130508)
I don't buy into that. For one, I've never seen one go that cheap (but then it's been over a year since I looked). Back when I was looking, typical prices for a 50 year old Cessna 150 was >$50k, unless it needs $30k worth of work done to it. Hard to believe they'd drop that much in only a year or so. Beware planes being sold in areas that have flooded (TN, LA) too, as they require tear-down inspections.

Also, to debunk the "they're unsafe" line:

"How Safe Are Amateur-Built/Homebuilt Aircraft?

Studies by FAA and the National Transportation Safety Board (NTSB) show that Amateur-Built/Homebuilt aircraft have an accident rate less than one percentage point higher than the general aviation fleet. In fact, the accident rate for Amateur-Built/homebuilt aircraft is dropping. The total number of registered homebuilt aircraft is increasing by about 1,000 per year, while the total number of accidents has stayed virtually the same. Another good barometer of safety is insurance rates. Companies that insure both homebuilts and production aircraft charge about the same rates for owners of either type of airplane. That indicates a similar level of risk."

http://www.eaa.org/homebuilders/faq.asp

Edit:

"Safety data on experimentals show them slowly approaching accident rates equivalent to those for small factory-made planes. And with some 25,000 experimental aircraft in the FAA's registry and another 1,000 added each year, more amateur-built than factory-built airplanes have been registered during each of the past five years, according to Bob Warner, executive vice president of the Experimental Aircraft Association."

I'm not sure where you're looking, but you'd need to be insane to pay $50k for a 150. Have a look on controller.com and you'll see prices range from about $15k to 30k. You can buy a perfectly safe and flyable 150 with a high-time engine for $15k.

As for accident data: I think the EAA statistic is misleading. I believe they are looking at total number of accidents. However amateur-built planes comprise only 10% of the GA fleet, and their fatal accident rate is 3-4 times that of the rest of the GA fleet per flight hour:

In the United States, the restrictions on an "ultralight" are rather severe:

> The governing regulation in the United States is FAR 103 Ultralight Vehicles, which specifies a powered "ultralight" as a single seat vehicle of less than 5 US gallons (19 L) fuel capacity, empty weight of less than 254 pounds (115 kg), a top speed of 55 knots (102 km/h or 64 mph), and a maximum stall speed not exceeding 24 knots (45 km/h or 27.6 mph). Restrictions include flying only during daylight hours and over unpopulated areas.

Re:First Open Source Airplane Could Cost Just $15,000 by ars on Tuesday July 30, 2013 @07:42AM (#6126315)
This is intended to be a light sport aircraft so the comparison is not completely valid.

LSA has 2 seats, take off weight 1300lb (600kb), max speed 120knots (138 mph), no specific fuel limit.

An ultralight is good for fun, but not practical for transportation. An LSA can be used as transportation - it's about 3 times faster than a car.

Re:First Open Source Airplane Could Cost Just $15,000 by rorrr2 on Tuesday July 30, 2013 @06:23AM (#6126117)
My point was, the biggest barrier to flying is not the price of the plane, but the desire to jump through all the hoops to get the license, to spend time/money on maintenance, to spend time on driving to the airport.
Re:First Open Source Airplane Could Cost Just $15,000 by emiliobumachar on Tuesday July 30, 2013 @07:07AM (#6126225)
Don't forget the relatively high risk of general aviation.
Re:First Open Source Airplane Could Cost Just $15,000 by supernovae on Tuesday July 30, 2013 @08:43AM (#6126529)
It's not a high risk mode of transportation.. It's about as "deadly" as driving a motorcycle. Sadly, if people paid more attention to motorcycles on the road, then motorcycles would be exponentially safer and if people stopped flying into bad weather then airplanes would be exponentially safer. With that being said, there is no "Relatively high risk of general aviation".. there are lots of careers and hobbies with a much higher risk.. in fact, if I remember correctly more people die of boating accidents going out on a lake than GA aircraft.
Re:First Open Source Airplane Could Cost Just $15,000 by katem on Tuesday July 30, 2013 @10:42AM (#6127183)
Of course more people die in boating accidents than in GA aircraft, there is way more boating.
Re:First Open Source Airplane Could Cost Just $15,000 by mikeash on Tuesday July 30, 2013 @10:56AM (#6127261)
Motorcycles are relatively high risk too.

GA is not some super-dangerous activity that's guaranteed to kill you. But let's not pretend that it's perfectly safe, either. Such an attitude does a disservice to all involved.

A GA pilot is still much more likely to die in bed than in his airplane, but the risk is substantially elevated compared to the average.

This comment misses the point and doesn't compare apples with apples. This is a 2 seat aircraft designed to operate in the Light Sport category which is very different from an Ultralight. Light Sport aircraft cost $70k and up.
Re:First Open Source Airplane Could Cost Just $15,000 by chuckd1356 on Tuesday July 30, 2013 @10:59AM (#6127283)
You can purchase a Cessna 150 for under $15k. And that's not a light sport.
Re:First Open Source Airplane Could Cost Just $15,000 by imbriaco on Tuesday July 30, 2013 @11:30AM (#6127553)
You should also point out that's a 20 year old Cessna 150.
Re:First Open Source Airplane Could Cost Just $15,000 by fr0sty on Tuesday July 30, 2013 @11:32AM (#6127574)
The last Cessna 150 was made in 1977 so it would be at least 35 years old.
Re:First Open Source Airplane Could Cost Just $15,000 by TheAnimus on Tuesday July 30, 2013 @12:04PM (#6127871)
And so what! The engine certainly would be more modern. I just had some excellent fun flying in a Piper Cub on Sunday, it's about 3 times my age. Planes are not like cars, entire chunks of them are replaced on a regular basis materials prone to rust and similar corrosion aren't normally used.

It was my first time flying such a primitive old plane and honestly I hadn't had such fun since my first solo. I was walking round with such a grin.

Old planes aren't bad at all. They are tried and tested, meanwhile this design doesn't exactly look as modern as a Diamond or similar cheap to run glider-come-airplane so it's hard to be excited in all honesty.

Re:First Open Source Airplane Could Cost Just $15,000 by seanc722 on Tuesday July 30, 2013 @12:18PM (#6127988)
Agreed. It's amazing the conditions of some of the Cessna's that come in to where I work... It's often insanely difficult to tell how old it is just by looking at it (Though not every aircraft is taken care of the same).
Re:First Open Source Airplane Could Cost Just $15,000 by mikeash on Tuesday July 30, 2013 @10:52AM (#6127239)
There are reasons why LSAs cost $70k. They're not looking to fly anything until 2015, and that's lots of time for reality to seep in. I wouldn't be surprised if they discovered that $15k was optimistic by a factor of about 5....
Re:First Open Source Airplane Could Cost Just $15,000 by jamie_ca on Tuesday July 30, 2013 @02:39PM (#6129077)
You can buy a recent Quad City Challenger kit for much less than that, and even fully assembled by someone else you're looking in the $30k range http://en.wikipedia.org/wiki/Quad_City_Challenger#cite_note-...

I'm assuming they're planning on making it a partial kit, and if you're expected to 3d print some of the parts $15k for "other" supplies (mostly avionics and engine) sounds pretty reasonable to me.
