Narrative:

Safety recommendation 02/tue/02 of the NTSB warned pilots that rudder deflection of all commercial aircraft are now suspected of being capable of causing damage to the vertical stabilizers of large aircraft. The specific rudder deflections by the NTSB refer to the accident of flight abc airbus 300-600 that crashed 11/mon/01. Deflections range 0 to 10.5 degrees of deflection. The pilots flying A300 received bulletin for A300 number xoa 06/sun/99. In a recent incident an A300 experienced uncommanded rudder inputs which included rudder deflections of up to 12 degrees. I can not control such events as an operation pilot. The NTSB says that vertical fin of any large aircraft may separate with rudder inputs that have been experienced on the A300. How are we supposed to control such inputs uncommanded. Turn off hydraulic systems. Please send guidance or better yet, no flying the A300 until the guidance is received. We are without any knowledge of how to comply.

Title: AN AIRBUS 300-600 CAPT REQUESTS CTL PROCS TO BE FOLLOWED ON UNCOMMANDED RUDDER DEFLECTIONS.

Narrative: SAFETY RECOMMENDATION 02/TUE/02 OF THE NTSB WARNED PLTS THAT RUDDER DEFLECTION OF ALL COMMERCIAL ACFT ARE NOW SUSPECTED OF BEING CAPABLE OF CAUSING DAMAGE TO THE VERTICAL STABILIZERS OF LARGE ACFT. THE SPECIFIC RUDDER DEFLECTIONS BY THE NTSB REFER TO THE ACCIDENT OF FLT ABC AIRBUS 300-600 THAT CRASHED 11/MON/01. DEFLECTIONS RANGE 0 TO 10.5 DEGREES OF DEFLECTION. THE PLTS FLYING A300 RECEIVED BULLETIN FOR A300 NUMBER XOA 06/SUN/99. IN A RECENT INCIDENT AN A300 EXPERIENCED UNCOMMANDED RUDDER INPUTS WHICH INCLUDED RUDDER DEFLECTIONS OF UP TO 12 DEGS. I CAN NOT CTL SUCH EVENTS AS AN OP PLT. THE NTSB SAYS THAT VERTICAL FIN OF ANY LARGE ACFT MAY SEPARATE WITH RUDDER INPUTS THAT HAVE BEEN EXPERIENCED ON THE A300. HOW ARE WE SUPPOSED TO CTL SUCH INPUTS UNCOMMANDED. TURN OFF HYDRAULIC SYSTEMS. PLEASE SEND GUIDANCE OR BETTER YET, NO FLYING THE A300 UNTIL THE GUIDANCE IS RECEIVED. WE ARE WITHOUT ANY KNOWLEDGE OF HOW TO COMPLY.
