A mechanic describes finding cracks in both sides of this original bulkhead in the upper corners of the rudder cable cutouts -- between the cutouts and the flange. “Dye penetrant inspection of the front of the flange revealed no defects. Inspection of this bulkhead was previously accomplished at 3,607.0 hours—not required for inspection under AD 72-07-09 until 4,607.0 hours. (I) recommend shorter inspection intervals.” (This cracked...) bulkhead (P/N 712616-1) was replaced. (Search of the SDRS data base returns 50 bulkhead related defects on the 182 series aircraft.)

Part Total Time: 4,470.3 hours.
