Engineering Notice

Reference drawing #14 plans serial numbers 256 or below: The inboard flap levers should be attached to the flap torque tube (3/4"X.049) by welding on the end as shown in the sketch below.

The AN3 bolt attachment method as shown on drawing #14 is not what was used on the prototype N6890R and may not hold up in the long run. If the bolt holes have been drilled, the bolts may be reinstalled if you wish, but the bolt is not required.
