Background: | A report was received of a disbond on the composite rudder control rod on a Model A320 aircraft. Investigation revealed the disbond was due to an incorrect low volume of resin in the fibre composite. The supplier and Airbus have confirmed that some rudder control rods installed on A330 aircraft before delivery or delivered as a spare are also affected. Rudder control rod rupture can lead in the worst case, in combination with a yaw damper runaway, to an unsafe condition. |
