Flutter Investigations on a Transavia PL12/T-400 Aircraft
Abstract
The Transavia T-400 Skyfarmer is the latest version of the twin-boom agricultural aircraft and incorporates several changes from the T-300 aircraft. In a ferrying flight in weather conditions which would not normally be experienced during agricultural work, an incident occurred which is believed to have been a limited amplitude flutter of the rudder and tail boom at a frequency around 3.5 Hz. In subsequent tests, the test pilot found that he could induce a similar oscillation by applying more than 50% rudder actuation in a series of quick jabs in alternate directions. This report details the subsequent activity to find a solution to the problem, and the tests conducted to verify the effectiveness of the solution.
