58-12-02 PIPER: Applies to All Models J-3, PA-11, PA-15, PA-16 and PA-17 Aircraft. Compliance required not later than July 15, 1958. There is a possibility that some aileron hinge reinforcing brackets P/N 10931-02 supplied to the field during the past three years were fabricated from aluminum instead of steel. Brackets, which have been replaced since June 1954, must be inspected to determine the type of material. All aluminum brackets are to be removed and replaced with steel brackets. (Piper Service Bulletin No. 165 covers this subject.)
