PA-31T2 Cheyenne 11XL
In 1977 the PA-31T with two 325hp engines became the PA-31T Cheyenne II, after the production of the ill powered PA-31T1 Cheyenne I (2xPTA-11 of 500hp). Then, in 1981, Piper produced the PA-31T2 Cheyenne IIXL with a lengthened fuselage and two 750hp PTA-132 engines. By 1986 only the PA-31-350, PA-31T1 and PA-31T2 were still on the production line, and Piper decided to roll out the PA-31P-350 Mojave, a Cheyenne with 350 hp engines. The Navajo six/eight seat cabin class twin has been adapted to a number of commuter, charter, air taxi, light freight and executive transport roles, and has spawned a series of developments. The PA-31P-350 Mojave was the last pressurised version of the PA-31 series to be built, while the PA-31-350 Chieftain was a stretched Navajo, built on the smaller Navajo's success in the commuter and charter roles. The stretched Navajo Chieftain first appeared in 1973, after Piper began design work in 1971 (delays were caused by the destruction of the second prototype and early production aircraft due to flooding at Piper's Lock Haven plant in June 1972). Originally dubbed the Navajo II, the Navajo Chieftain was intended to compete against the Cessna 402 and to a lesser extent the turboprop powered Beech 99. Piper Pa31 / Pa42 Navaho Chieftain Cheyenne performance and specifications Three versions were offered : a 8 seat liaison aircraft, a 6 seat standard aircraft and a 6 seat luxury aircraft. At the same time Piper also started production of the PA-31-310 Turbo Navajo B fitted with two 310hp engines. Later in March 1970 the PA-31P Pressurized Navajo made its first flight with two 425hp engines, and a pressurized cabin that allowed it to reach 8,000 meters. The next version was the PA-31-350 Navajo Chieftain characterised by two 350hp engines and especially a fuselage 61cm longer. But the most advanced version, the PA-31T Cheyenne, certified in 1973, had a pressurized cabin and two Pratt&Whitney Canada PTA-28 620hp engines.
