Economy at 12,000 is about 158 KTAS burning 13 gph. They are properly termed "turbonormalized" since the compression ratio and maximum manifold pressure remained unchanged. The PA-23-150 Apache seats up to 4 passengers plus 1 pilot. This aircraft was designated the Apache 235. The AFM said something very close to: Flight into light to moderate icing conditions is approved if the aircraft is equipped with . 22 GPH – Consult POH System Description: The airplane is equipped with a standard fuel system consisting of four vented fuel tanks, two fuel tank selector valves, fuel strainers, two manual primers, an engine-driven fuel pump for each engine, and an auxiliary electric fuel pump for each engine. Since there is no accompanying power increase, the B/C models simply give owners a fuel vs. passenger tradeoff. That's one of the best things about PoA...the knowledge exchange. With FAA approval the twin carried a total of 252 gallons in 11 tanks and at maximum power went over 2,100 miles nonstop between Marrakech, Morocco and Istanbul, Turkey in 11:19 hours.. http://www.pilotsofamerica.com/forum/showthread.php?t=85587, (You must log in or sign up to reply here. At the time, well known aviation journalist, Richard L. Collins, was highly critical of the FAA's multiengine training standards which encouraged unsafe Vmc demonstrations at low altitude. , In the 1970s, the FAA changed its training standards and required flight instructors to obtain a separate rating to teach in multiengine aircraft. ). One was scrapped by Piper and none remain registered with the FAA as of November 2019.. Pilots are required to use care to avoid overboosting at low altitudes, since no overboost popoff valves are used. Roberston STOL kit lowers VMC to 80 MPH. Fuel burn at typical cruise settings is approximately 16 gal/h (58.7 L/h) with a cruise speed of 165 kn. The Piper PA-40 Arapaho had been scheduled to replace the PA-39 in the 1973-4 timeframe. Landing gear type: Tri/Retr. ), Paraphrasing the late Gordon Baxter "The cost of flying today is exactly the same as it was 50 years ago...all you got...".

I don't think it does. Following a string of accidents involving pilot loss-of-control in single-engine flight (due to engine failure, or in pilot training for engine-failure conditions), Piper sought to alter the plane's single-engine behavior at low airspeeds (such as takeoff and landing). Of course, the 182 carries 100 pounds more and cruises 25 knots faster, burning 3 to 4 GPH more fuel. Her operating costs are more comparable to a big single as she has two little engines (160 hp) rather than one big one. I've never bothered to add everything up, but I use the $275-300/hour number for light twins of the Aztec/310/Baron category. The insurance and maintenance of a twin will be a wash, considering the high hull rates on the more expensive airplane. In 1997, the Aircraft Owners and Pilots Association (AOPA) Air Safety Institute published a safety review of the Comanche series aircraft and concluded that the Twin Comanche showed no greater tendency for Vmc roll-over spins than comparable aircraft. With tip tanks, the aircraft holds 120 gallons (454 L) of fuel. On 21 March 1964, a Piper PA-23-160 Apache (G-ASHC) crashed on its approach to Aintree racecourse, near Liverpool, killing all 5 on board. , The Twin Comanche was produced on the same Lock Haven, Pennsylvania, production line as its single-engined cousin; production ceased when the factory was flooded in 1972.

When compared with the Seminole, the Twin Comanche goes faster, carries more, burns less fuel, climbs more rapidly and ultimately higher, is quieter. Every one, no exceptions, was under the [mistaken] impression that Piper had. That makes a lot more sense. Not sure if that still applies anymore or not. Factory turbocharged engines became available with the B model. As the model years progressed, the payload Delta between the two increased. We expect to have them resolved in the next 24 hours We calculate Aircraft Valuations, Total Ownership Cost which include Fixed Costs such as Insurance, Hangar, and Depreciation, as well as Variable Costs such as Fuel Consumption (GPH and dollar cost). The way I fly, I average about 15 gph. It seems like my guess is pretty close to what those who have added it up have come up with. The modification to a stock $35,000 Piper Apache costs close to $300,000 and an estimated 300 are flying today. My Aztec left the factory with boots, electric cuffs on the props, heated glass windshield plate, ice light (mounted on the left engine cowl and illuminates the wing leading edge), higher amp alternators on both engines, a modified heated alternate air intake and ice shields on the nose panels in line with the propeller arcs. Fuel burn at typical cruise settings is approximately 16 gal/h (58.7 L/h) with a cruise speed of 165 kn. Gross weight (lbs. He flew it from the United Kingdom to Nigeria, where he held a diplomatic post; then later returned in it to the United Kingdom and flew it to Japan when he took up a diplomatic post in that country. Pilots flying this modification have reported an increased useful load, better climb performance, increased cruise speed, lower fuel burn at cruise, and safer single-engine characteristics. That is not quite a correct statement of the law, but it is very confusing and not a lot of people fully understand it, including a number of FAA inspectors I have run into. One of the three Arapahos was destroyed in a flat spin accident in 1973; the test pilot, Clay Lacy, successfully escaped. , As of November 3, 2019, 80 PA-39's remain on the Federal Aviation Administration (FAA) registry. Airplane is a 1979 Piper Aztec 'F' with naturally aspirated IO-540 Lycomings; approximately 5500 TT and 1300 on the engines.

Burning (under an STC) a total of only about 16 gallons of auto gas per hour, the We still have non-alcoholic 87 unleaded here in Oklahoma and that really lowers the operational costs. Insurance was a little lower and hanger was higher so it balances out.  Collins pointed out in another article that year that one FBO had suffered four fatal Vmc roll-over spins. It was a twin-engined development of the PA-24 Comanche single-engined aircraft. He had the 60-gallon tanks as opposed to the optional 90-gallon-total fuel tanks, and burned 13.5 gallons per hour when power of the retractable airplane was set to 23 inches of manifold pressure and 2,400 revolutions per minute.

These two numbers seem incredibly high for an Aztec. • The plane has de-icing boots on its leading edges, de-icing for the props and a heated windshield. Three versions of the PA30 were produced: the original, a B model, and a C model. Careful leaning could probably get it even lower, and it's burning cheap 80 octane, besides. A version with turbocharged engines for higher altitude flight was also developed, using IO-320-C1A engines of the same nominal power. Piper chose at that time to focus on its equally popular Cherokee 140/180/235/Arrow line, manufactured in Florida, and its highly popular twin-engined Seneca, which is essentially a Twin Cherokee Six. In 1994 Jayne and her daughter, Patricia Jayne (Pat) Keefer won the FAI Gold Medal in what, so far, is the longest race in history at over 21,000 miles flown May 1–24, 1994.
