48-13-07 AERONCA: Applies to 11AC and S11AC Serial Numbers 1 Through 931.
Compliance required at next periodic inspection but not later than May 1, 1948.
To eliminate interference and failure of the turnbuckle forks at the attachment points of the two elevator control cables to the horn located on the bottom of the control column, inspect to determine that AN 161-16RS turnbuckle forks have been replaced by AN 160-16S forks. The distance between the bottom of the fork slot to the center of the attachment bolt on the new fork is 15/32 inch and the original fork is only 3/8 inch.
