Commercial Airplanes 727 Service Bulletin
SPECIAL ATTENTION SummaryNumber: 727-55-0095Original Issue: September 24, 2012 ATA System: 5500 SUBJECT: STABILIZERS - Vertical Stabilizer - Fin Closure Rib - Chord Inspection BOEING RECOMMENDS THAT EACH OPERATOR EXAMINE THIS SERVICE BULLETIN IMMEDIATELY.
CONCURRENT REQUIREMENTS None.
BACKGROUND This service bulletin gives instructions to inspect the left side and right side chords of the fin closure rib for cracking or corrosion. The fin closure rib is located at the top of the vertical fin structure. The chords of the fin closure rib support the horizontal stabilizer hinge fittings. If the work in this service bulletin is not done, widespread cracking in the chords may weaken the fin closure rib structure which could result in loss of airplane control due to lack of horizontal stabilizer support.
One operator reported finding a crack on the left side chord of the fin closure rib during a routine maintenance inspection. The crack measured a maximum of 2.4 inches long and it ran along the length of the chord. The airplane had accumulated 5,303 flight cycles and 11,669 flight hours when the crack was found. Cracking at this location is the result of intergranular stress corrosion caused by the material properties of 2024-T351 extrusion from which the closure rib chord is made. This material becomes vulnerable after the surface finishes begin to break down as a result of normal in-service aging.
A fleet history search revealed that this occurrence is the first report of intergranular cracking of the chords. The Corrosion Prevention and Control Program (CPCP) and Maintenance Planning Data (MPD) documentation for 727 airplanes both contain visual inspections of the chords, but no NDT inspections. Accomplishment of the NDT and visual inspections in this service bulletin will make sure that any crack or corrosion in the left side or right side chords of the fin closure rib is detected.
