The airworthiness directive
46-12-01 CESSNA: (Was Mandatory Note 8 of AD-722-5.) Applies Only to AT-17 and UC-78 Series Airplanes.
Inspection required immediately.
On all AT-17 or UC-78 Series airplanes that have not been re-covered with grade A fabric at time of (or subsequent to) the original civil certification, inspect the fabric on wings and control surfaces to determine that the fabric complies with grade A fabric standards and has a sample breaking strength of at least 56 pounds. The lacing cord should also be checked and should have a breaking strength of at least 56 pounds when tested double. This inspection will require the testing of one or more samples of fabric and cord, the location from which the samples are to be taken and the number necessary will be determined by the CAA representative.
