Commercial Airplanes MD80 Service Bulletin ALERT SummaryNumber: MD80-55A069Original Issue: January 19, 2011 ATA System: 5511 SUBJECT: STABILIZERS - Horizontal Stabilizer - Inspect/Repair/Replace Horizontal Stabilizer Center Section Left and Right Rib Hinge Bearing Lugs
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 Boeing has received two reports of cracks being found on either the left or right MD-80 horizontal stabilizer center section ribs. These cracks were found on the aft face of the horizontal stabilizer hinge bearing lugs.
Cracks were reported on MD-80 airplanes with between 23,700 and 41,963 flight-hours and 23,300 and 35,294 flight cycles. In addition, eleven cracks at the same location have been reported in either the left or right, or in two cases, both of the MD-90 horizontal stabilizer center section ribs. Accordingly, MD-90 Alert Service Bulletin MD90-55A016 has been issued. Investigation by Boeing has yet to establish the definitive cause of these cracks.
Performing an Eddy Current, High Frequency inspection of the affected area will determine the existence of any crack. If not corrected, undetected cracks in the center section left and right rib hinge bearing lugs could spread at the same time which would cause both hinge bearing lugs to fail, resulting in the horizontal stabilizer being unable to sustain the required loads.
ACTION This service bulletin gives instructions to do an Eddy Current, High Frequency inspection of the horizontal stabilizer center section left and right rib hinge bearing lugs for cracks and does as follows:
CONDITION 1 (No Crack Found in Rib Hinge Bearing Lug)
1. Repeats the Eddy Current, High Frequency inspection at defined intervals.
CONDITION 2 (Crack Found in Rib Hinge Bearing Lug)
1. Measures the crack length and does as follows:

b. Repetitively inspects blend out area for cracks, using Eddy Current, High Frequency inspection.
CONDITION 2B (Crack Length Between Points 'A' and 'B' is Greater Than 0.15 Inch, or Crack Length Between Points 'C' and 'D' is Greater Than 0.05 Inch)
a. Replaces horizontal stabilizer center section rib.
b. Does Eddy Current, High Frequency inspections at a defined threshold.
