Compliance required as indicated. Service experience has shown that a gap of less than 0.25 inch between the end of No. 3 flap and the aileron may, under certain flight conditions, produce a condition where the flap could foul or contact the inboard end of the aileron (port and starboard wings). As soon as possible but not later than June 15, 1959, inspect for adequate clearance between the outboard end of the No. 3 flap at the No. 4 flap beam unit and the inboard end of the aileron on both the right and left sides. Where the gap is found to be less than 0.25 inch, the outboard end of the No. 3 flap must be modified to provide proper clearance. The British Air Registration Board considers this mandatory.
