Applies to Models PA-18 and PA-18A Series aircraft Serial Numbers 18-1 through 18-7768 inclusive. Compliance required within the next 25 hours' time in service after the effective date of this AD unless already accomplished. Several failures have been reported of the rudder cable attachment fitting lug, P/N 40831, at the weld on rudder pedals, P/N's 40842-04 and 40842-05. Accordingly, the following shall be accomplished: Visually inspect the weld that attaches the rudder cable lug, P/N 40831, to the foot bar tube on both left and right rudder pedals for evidence of separation, cracks in the weld, insufficient length of weld, or excessive wear of weld. A weld of sufficient length must cover at least the top half perimeter of the tube (minimum). If the weld is separated, cracked, excessively worn, or of insufficient length, replace the rudder pedal assembly prior to further flight. (Piper Service Bulletin No. 207A, dated May 10, 1962, covers this subject.) This directive effective January 23, 1962.
