- If safety wire is installed such as to prevent examination of the fitting surface, the safety wire must be removed. Caution: Care should be taken to avoid any adjustment of the turnbuckle relative to the fittings. Otherwise, re-rigging of the affected flight control cables per the manufacturer’s instructions should be done before further flight.
- Examine underneath any sleeving or tape that is installed on the fitting shank.
- Remove and discard any such tape or sleeve material while exercising care not to gouge or scratch the fitting surface. Removal of this material is considered a minor alteration to the airplane and should be documented by an appropriate logbook entry.
- Replacement of any identification marking can be accomplished using normal airplane metal marking techniques such as paint stencil or low chloride permanent marker. Avoid using generic permanent markers, as they may contain chlorides. Low chloride markers are commercially available.
- Use of a 10X magnifier is recommended.
- Apply a corrosion preventative to the swaged fittings if recommended by the manufacturer.
- Replace any removed safety wire with new safety wire in accordance with normal procedures.
