The airworthiness directive
47-10-32 LOCKHEED: (Was Service Note 2 of AD-763-3.) Applies Only to Model 49 Serial Numbers 2021 to 2067, Inclusive.
At each periodic inspection, examine the upper wing surface forward of the aileron beam and just outboard of Station 458 joint for the presence of buckles. If serious buckles are found the skin in that area should be replaced and gussets added. After the entire affected area (approximately 5 inches x 36 inches) has been reworked in this manner, no further periodic inspections will be required.
(LAC Service Instruction 49/SI-26 covers this same subject.)
