5.8 RUDDER FLUTTER

Flutter is a self-feeding vibration due to an aerodynamic instability.
The tail rudder is affected by the propeller airstream and could enter
in flutter if steering control cable is not assembled with the correct
tension. It is so important for your safety to follow the maintenance
instructions of the maintenance manual.
If for any reason, you feel some rudder vibration and self-movement
in your pedals, you should reduce the airspeed by reducing the
engine power and maintain attitude until the vibration stops.
Then fly carefully back to the nearest airfield for inspection.
