MANDATORY MANDATORY MANDATORY ATA SYSTEM: 55 TITLE: STABILIZERS - RUDDER - A300-600 RUDDER DEBOND INSPECTION **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES On AIRBUS A300-600 aircraft, most of the rudder side shells are sandwich structures made of Carbon Fiber Reinforced Plastic (CFRP) and Glass Fiber Reinforced Plastic (GFRP) with a honeycomb core, like on AIRBUS Single Aisle family aircraft. A debonding in a rudder shell was found on the rudder of an A319 and an A321 aircraft. A large rudder debond, resulting from an undetected damage growth, could affect the handling quality of the aircraft. Under specific conditions, a large debond could lead to aircraft in-flight instability. A review of the production records revealed that the debonding reported on both rudders correspond to areas that had been reworked in production. This Service Bulletin details the special detailed inspection procedure to inspect the reworked areas on affected rudders fitted on the A300-600 aircraft for potential debonding. Due to the different areas on the rudder to be inspected, different inspection procedures are necessary: - Vacuum loss inspection - Elasticity Laminate Checker (ELCH) inspection - Tap test inspection - Thermography inspection - Ultrasound (US) inspection. The accomplishment of this Service Bulletin will ensure the detection of potential debonding in the reworked areas.

REASON (1) History On AIRBUS A300-600 aircraft, most of the rudder side shells are sandwich structures made of Carbon Fiber Reinforced Plastic (CFRP) and Glass Fiber Reinforced Plastic (GFRP) with a honeycomb core, like on AIRBUS Single Aisle family aircraft. A debonding in a rudder shell was found on the rudder of an A319 and an A321 aircraft. A large rudder debond, resulting from an undetected damage growth, could affect the handling quality of the aircraft. Under specific conditions, a large debond could lead to aircraft in-flight instability. A review of the production records revealed that the debonding reported on both rudders correspond to areas that had been reworked in production. (2) Objective/Action This Service Bulletin details the special detailed inspection procedure to inspect the reworked areas on affected rudders fitted on the A300-600 aircraft for potential debonding.
