Unsafe Condition
Excessive axial play detected on bearings installed on certain single hydraulic main and tail rotor servo-controls could cause the distributor slide valve to jam in its sleeve, jamming the hydraulic flight controls and necessitating that the pilot cut off hydraulic power.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect the servo-control's component history card or equivalent record to determine if it has a certain part number and serial number or if it was repaired or overhauled by UTC Aerospace Systems or Goodrich Corporation. If either condition exists, inspect the identification plate and bearing for specific markings. Replace the servo-control with an airworthy one if no marking is found or if the sealing flange is not marked with 'RWG Germany 60-5593'.
