The Piper PA-32 Cherokee Six is a series of six or seven seat, fixed landing gear, light aircraft, that was manufactured in the United States by Piper Aircraft between 1965 and 2007. The big Six is a prodigious people packer. Resembling a stretched version of the basic Cherokee airframe, it provides slight twin performance with single-engine economy. The Six was introduced in 1965 with a 260-hp engine, which some pilots seem to feel was not quite enough power. So the people at Piper decided to offer the option of the 300-hp powerplant up front in 1970. Basically a six-seater, the largest of the Cherokees is easily converted to handle a large amount of cargo loaded through its spacious rear double doors; thus it performs as a double-duty passenger utility airplane. Besides the standard six-seat arrangement with center aisle, there is a seventh-seat option. In 1978, increased speeds of 7 mph made the Cherokee Sixes the fastest planes in their class. A 5% increase in range is also a product of overall drag reductions, a refined powerplant, and new Piper-engineered speed fairings. In 1979, the single-engine workhorse was fitted with a 98-gallon capacity fuel tank and structurally integrated fuel system popularized by the Lance. The new fuel system increased the Six?s range by over 100 miles at many power settings. At 65% best power, the Six?s range is 923 miles.
