Narrative:

On departure at approximately 100 ft afl we felt what could best be described as a 'rudder kick.' the airplane felt as though it was pushed laterally from the right to the left approximately 3 to 5 ft. This was not a normal sensation and the 'rudder kick' was felt in the pedals as well. Callback conversation with reporter revealed the following information: the reporter stated the aircraft was to be maintenance ferried from ZZZ to an overhaul facility to investigate and correct a reported rudder and rudder pedal oscillations in climb. The reporter said ZZZ maintenance had checked the rudder rigging, trim, and yaw damper operation. The reporter stated the flight control system engineer was to accompany the crew on the flight and wanted to fly a profile flight to attempt to duplicate the oscillation report. The reporter said this was refused as neither myself nor the first officer were qualified test pilots. The reporter stated on takeoff about 50 ft to 100 ft we felt a rudder kick in the left rudder pedal and the airplane was shoved abruptly to the left. The reporter said his experience on this airplane exceeds 10 yrs, 7 as first officer and 3 as captain and had never felt this very strange feeling of a lateral shove. The reporter said this incident was not wind related and was too abrupt. The reporter stated the remainder of the flight was normal and uneventful. The reporter said the next day a flight test crew operated the airplane and reported the #1 yaw damper dropped off with no reset. The reporter stated maintenance has not advised the flight crew of any maintenance action after the test flight.

Title: AN AIRBUS 300-600 ON TKOF CLB AT 100 FT EXPERIENCED A RUDDER KICK MOVING THE AIRPLANE FROM R TO L LATERALLY 3 TO 5 FT AND FELT IN RUDDER PEDALS.

Narrative: ON DEP AT APPROX 100 FT AFL WE FELT WHAT COULD BEST BE DESCRIBED AS A 'RUDDER KICK.' THE AIRPLANE FELT AS THOUGH IT WAS PUSHED LATERALLY FROM THE R TO THE L APPROX 3 TO 5 FT. THIS WAS NOT A NORMAL SENSATION AND THE 'RUDDER KICK' WAS FELT IN THE PEDALS AS WELL. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE ACFT WAS TO BE MAINT FERRIED FROM ZZZ TO AN OVERHAUL FAC TO INVESTIGATE AND CORRECT A REPORTED RUDDER AND RUDDER PEDAL OSCILLATIONS IN CLB. THE RPTR SAID ZZZ MAINT HAD CHKED THE RUDDER RIGGING, TRIM, AND YAW DAMPER OP. THE RPTR STATED THE FLT CTL SYS ENGINEER WAS TO ACCOMPANY THE CREW ON THE FLT AND WANTED TO FLY A PROFILE FLT TO ATTEMPT TO DUPLICATE THE OSCILLATION RPT. THE RPTR SAID THIS WAS REFUSED AS NEITHER MYSELF NOR THE FO WERE QUALIFIED TEST PLTS. THE RPTR STATED ON TKOF ABOUT 50 FT TO 100 FT WE FELT A RUDDER KICK IN THE LEFT RUDDER PEDAL AND THE AIRPLANE WAS SHOVED ABRUPTLY TO THE LEFT. THE RPTR SAID HIS EXPERIENCE ON THIS AIRPLANE EXCEEDS 10 YRS, 7 AS FO AND 3 AS CAPT AND HAD NEVER FELT THIS VERY STRANGE FEELING OF A LATERAL SHOVE. THE RPTR SAID THIS INCIDENT WAS NOT WIND RELATED AND WAS TOO ABRUPT. THE RPTR STATED THE REMAINDER OF THE FLT WAS NORMAL AND UNEVENTFUL. THE RPTR SAID THE NEXT DAY A FLT TEST CREW OPERATED THE AIRPLANE AND RPTED THE #1 YAW DAMPER DROPPED OFF WITH NO RESET. THE RPTR STATED MAINT HAS NOT ADVISED THE FLT CREW OF ANY MAINT ACTION AFTER THE TEST FLT.
