Overview
The Cessna 441 Conquest II is the first turboprop powered aircraft designed by Cessna, and was meant to fill the gap between their jets and piston-engined aircraft. It was developed in November 1974, with the first aircraft delivered in September 1977. It is a pressurized, 8–9 passenger turbine development of the Cessna 404 Titan.
Development
The original design from 1972 for this aircraft was known as the Model 435, and was to be powered by Continental GTSIO-520X engines with three-bladed propellers. By 1975, the designed evolved into the turboprop-powered Model 441. It was certified by the FAA on August 19, 1977. Cessna renamed the Model 441 the Conquest II in 1983.
1984 models starting with constructor number 195 used lighter weight four-bladed McCauley propellers. A 441 with Pratt & Whitney Canada PT6A-112 turboprops was flown in 1986, but did not enter production.
A smaller aircraft was marketed as the Cessna 425 Conquest I, itself a turbine development of the Cessna 421.
In September 2007, Cessna limited the Conquest II to 22,500 hours of air time though a Supplemental Inspection Document. This makes it effectively mandatory for US for air carriers, but only advisory for private operators.
Cessna built 362 of the aircraft between 1977 and 1986.
