## Summary

We propose to supersede Airworthiness Directive (AD) 2005-17- 14, which applies to all Airbus SAS Model A300 series airplanes; Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes); and Model A310 series airplanes. AD 2005-17-14 requires repetitive tests to detect desynchronization of the rudder servo actuators, and adjustment or replacement of the spring rods of the rudder servo actuators, if necessary. AD 2005-17-14 also requires repetitive tests/inspections/analyses of the rudder servo actuators, and related investigative/corrective actions if necessary. Since we issued AD 2005-17-14, analyses of the inspection results indicated that the assumptions made to establish the survey campaign were not adequate, and a new investigation determined the existing inspection procedures and compliance times do not adequately address the unsafe condition. This proposed AD would retain some requirements of AD 2005- 17-14 and revise the inspection procedures and compliance times, as specified in an European Aviation Safety Agency (EASA) AD, which will be incorporated by reference. We are proposing this AD to address the unsafe condition on these products.
