To prevent failure of the Slider, accomplish the following one-time inspection for proper hardness: Remove the Slider in accordance with Section VI of the Model 204B Maintenance Manual. Determine the hardness of the Slider using hardness tester. Reading should be taken on the side of the flat plate. Reinstall only Sliders with a tensile hardness reading of 125,000 P.S.I. to 145,000 P.S.I. in accordance with Section VI of the Model 204B Maintenance Manual. For Sliders on tail rotor assemblies with less than 300 hours time in service, conduct the above inspection before further flight unless already accomplished. For sliders on tail rotor assemblies with 300 hours or more time in service, conduct the above inspection within the next 125 hours' time in service unless already accomplished. For spare Sliders, conduct the inspection before installation, unless already accomplished.

(Bell Service Bulletin No. 204B-3 dated August 15, 1967, also pertains to this subject.)
