This equates to six adults and 250 pounds of luggage. For both individual and corporate owners, the early Cheyennes make sense as step-up purchases, as long as the combination of low price, low maintenance, and high-performance remains in vogue. The 400LS is the only twin-engine turboprop that can outperform single and twin-engine civilian turbine and light jets in door to door speed and piston twins in efficiency for a given payload. When I am not working, eating or sleeping, you can find me there. The Piper Cheyenne 400LS, PA-42-1000 is the final development and improvement of the venerable Cheyenne line of twin turboprop business aircraft. Radar and known-icing equipment are. However, as speed built up, so lateral stability improved and we were very Quality and quality control were not characteristics widely associated with Piper products of the time. We did a hot section on schedule on the right engine almost four years ago. important implications during ground handling. I just happened on this article. 0000006052 00000 n Operated within their limits, there are few peculiar characteristics other than the pitch sensitivity of the original Cheyenne.

Fuel is carried in six tanks three interconnected tanks in each wing: a wet nacelle tank, and two bladder-type fuel cells. The early Cheyennes were later refined with some aerodynamic improvements, but the PT6-28s produced only 10 to 15 percent faster cruise speed than their piston siblings and at a much higher fuel consumption. They made 620 shp, and therein lay a problem. 0000009642 00000 n Ours is one of only 44 total Cheyenne 400LS models built by Piper Aircraft between 1984 and 1992.

It takes about four inches of yoke travel to keep the plane level at FL 270. It is powered by PT6A-11 engines rated at 500 SHP. It is derived directly from the Cheyenne III series, but utilizes the far more powerful TPE331 engines with four-blade propellers which produce significantly faster airspeeds than its predecessors. off and attention must then be shifted to the EGTs. Flew one of these from Seoul, South Korea to the US (via Eastern Russia).
