Certification in the United Kingdom was not possible (and not even tried) because of pitch sensitivity and pitch force behavior and feel, which encouraged pilot-induced pitch oscillations rather than damping the tendency. Even if misuse or abuse of a system or poor procedures dont lead to an incident or accident, improper operation can easily lead to unserviceability and increased maintenance cost.

Swearingens facility for installation of a pair of PT6A-6A engines. It was costly close to $40,000. In ground handling and during cross-wind operations it is especially troublesome, since it fights the desired control inputs.

The comments in the accident brief note that the regular pilot refused the trip because of the weather. Turboprop Aircraft. Back in the 1980s, Piper employed Gen. Chuck Yeager to set various time-to-climb records in the 400LS. This means that, for example if an aircraft is trimmed to 100 knots, a positive pull on the yoke is needed to maintain, say, 90 knots.

It is derived directly from the popular III series but utilizes powerful TPE331 engines with four blade propellers which produce faster airspeeds than its predecessors! first flew in October 1969.

Des Moines Flying Service does an excellent lob getting parts from any source possible. Of the original 44 aircraft, just over 20 are believed to be flying in the United States today. Operated within their limits, there are few peculiar characteristics other than the pitch sensitivity of the original Cheyenne. A total of 526 aircraft were built. Physical dimensions are the same as the PA-31T except that the basic airplane wingspan is two feet shorter (40 feet, 8 inches versus 42 feet, 8 inches) because in standard form it does not have tip tanks (although most purchasers opted for them).
