Commercial Airplanes 767 Service Bulletin ALERT SummaryNumber: 767-57A0126Original Issue: August 12, 2011 ATA System: 5710 5350 SUBJECT: Wing - Center Wing - Lower Underwing Longeron Fitting at FWD Intersection of Fuselage and Wing Skin - Inspection and Replacement
THIS BULLETIN IS SENT TO THE OPERATORS OF RECORD OF THE AIRPLANES SHOWN IN PARAGRAPH
1.A., EFFECTIVITY. IF AN AIRPLANE HAS BEEN LEASED OR SOLD, SEND THIS SERVICE BULLETIN TO THE NEW OPERATOR. IF APPLICABLE SPARES HAVE BEEN SOLD, SEND THIS SERVICE BULLETIN TO THE NEW OWNER.
CONCURRENT REQUIREMENTS None.
BACKGROUND The underwing longeron fittings must be inspected by High Frequency Eddy Current (HFEC) inspection to detect cracks in each underwing longeron fitting. If any crack is found in an underwing longeron fitting, that fitting must be replaced, and the tension bolt hole and the front spar lower chord adjacent to the underwing longeron fitting must be inspected for cracks. Further repair may be required. The underwing longeron fittings must be inspected periodically for cracks over the service life of the airplane. If you do not do this service bulletin, then cracks in the underwing longeron fitting could go undetected, potentially leading to a loss of the primary load path between the fuselage and the wing box. The loss of the primary load path could result in catastrophic damage to the wing box.
An operator reported finding cracks in the left and right wing center section underwing longeron fittings. The cracks found were in the same location on both fittings and appeared to run through the entire thickness of the forward edge of the fitting at the radius corner of the vertical/horizontal flange. The lengths of cracks were approximately 0.300 to 0.375 inches long. The airplane had accumulated 37,000 flight-cycles.
Similar cracks were found on a fatigue test airplane at these locations. Boeing estimates that it would take 25,000 cycles for the cracks to grow from 0.375 inches to 1.8 inches.
Another operator reported finding a crack in the left wing center section underwing longeron fitting during normal maintenance. The length of crack was approximately one inch long and started from the radius of the fitting flange. The airplane had accumulated 16,655 flight-cycles.
If you do this service bulletin you will prevent a possible loss of a primary load path due to the subject mode of crack development.
