Regulatory Text

58-01-07 PIPER: Applies to All J-3 Series and J-5 Series Aircraft.

Compliance required by February 1, 1958.

To preclude the possibility of failures of the fork end of the turnbuckles in the control system, the following inspection and rework is necessary. Failures of the fork end of the turnbuckles have occurred in the area covered by the safety wire. This results from binding caused by the attaching bolt being drawn up too tightly on the fork end of the turnbuckle.

Inspect the turnbuckle to horn attachment at the elevators, rudder and ailerons to determine that an AN 23-12 clevis bolt is installed with one AN 960-10 washer under the nut. This assembly should swivel freely.
