The airworthiness directive
47-49-09 LOCKHEED: (Was Service Note 9 of AD-763-3.) Applies to All Model 49 Serials Up to and Including 2088 and to Models 649 and 749 Serials 2501 Through 2513, Inclusive.
At each engine change period, inspect the wing attaching pins at Station 80 to determine whether any of these pins are working upward through the fittings. If any pin has worked up until only the lower chamfered portion protrudes, replace the Station 80 cover strip with a new 0.064 24ST alclad strip. When this strip has been replaced the periodic inspection of that joint may be discontinued.
