2. If inspection reveals that there are no missing welds, no further action is required and the aircraft may be approved for return to service.

3. If inspection reveals missing welds, replace rudder control bar assembly P/N 601031-501 with a new part of the same part number.

4. If parts are unavailable, repair may be accomplished by contacting the local FAA Maintenance Inspector concerning a repair procedure which must be approved by the Chief, Engineering and Manufacturing Branch, Great Lakes Region.
