To comply with14 CFR 23.1529, continue the new stretcher and restraint systems on the same inspection and maintenance schedule used per the applicable Daher, or Pilatus Maintenance Manual for seats as applicable. a. The new stretcher and restraint systems require no service other than inspection at normal inspection interval of 100 hours or annually. b. Perform a detailed visual inspection of the portable stretcher covering to detect apparent or obvious defects or irregularities. Visually inspect the covering assembly for holes, punctures, and tears. If the damage to the covering is holes smaller than ½” in diameter or a cut at a maximum of 2” in length then the covering is satisfactory. The sewing of the cover assembly cannot have a tear or cut exceeding 1” in length. Any damage to the covering assembly outside of the described limits will require it to be replaced. c. Visually inspect the stretcher support assemblies for cracks and deformation. Damaged conditions can be detected as a crack at the edge of the tube or along the length of the tubes. Visually inspect all hardware for excessive wear before and after installation. There shall be no broken aspects of the support assemblies. There shall be no sharp corners, edges, or protrusions that may injure passengers. Replace the tubes if they are bent in such a way that they are more than 1” off center. Replace or repair the stretcher support assembly if a crack length is found to be .125” or greater. Replace the support assembly if a dent is found in the tube running longer than 3”.
