REGULATORY TEXT:  
47-30-04 CESSNA: (Was Service Note 4 of AD-722-5.) Applies to T-50 Aircraft.

Inspect the landing gear chains and chain dampener mechanism for the following at each 100-hour inspection. The landing gear chain should be tight and pressing firmly against the drive and idler sprockets. With the chain pulling tight against the idler sprockets the slotted dampener link should permit movement of the spring dampeners. The dampener spring is correctly adjusted when compressed to 3/8 inch. All sprockets should be inspected for excessive wear. The sprockets are considered excessively worn and should be replaced when the teeth are one- half the thickness of the sprocket web. All guards should be inspected to make sure there is no danger of binding or jamming. Inspect all links of the landing gear chain for cracks and replace any links that are found cracked. It is recommended that the chain be replaced every 1,000 hours.
