Commercial Airplane Group 727 Service Bulletin Number: 727-57-0112 Revision Transmittal SheetDate: September 2, 1970 Revision 5: July 31, 1997 ATA System: 5712 SUBJECT: WINGS - RIB UPPER CHORD AT BL 70.5 - INSPECTION, MODIFICATION, AND REPAIR This revision includes all pages of the service bulletin.
COMPLIANCE INFORMATION RELATED TO THIS REVISION No more work is necessary on airplanes changed by Revision 4 of this service bulletin.
More work is necessary on Group 1 airplanes changed by Revisions 2 or 3, Part V of the Accomplishment Instructions of this service bulletin. On Group 1 Airplanes with the Major Repair/Preventive Modification installed, it is necessary to make an inspection at BL 70.5 for a repair strap. If a strap is not installed, it is necessary to make an inspection of the frame for cracks.
SUMMARY This revision is sent to tell operators that new kits are available for Group 1 and 2 Airplanes. The drawings used to install the kits are sent with this revision (the drawings have been revised since the release of Notice of Status Change 3). The format used to show the removal of parts and installation of the kits has changed.
Also repairs, that operators have requested, are included, and the compliance information has been clarified.
This revision is sent to tell the 727 airplane operators that this service bulletin has been identified by the 727 Structures Working Group (SWG), and the structural change and inspection given in this service bulletin are recommended to be included on applicable 727 airplanes. The change and inspection given in this service bulletin must be included at the times given in the Description and Accomplishment Instructions.
As a result of the Aging Fleet Conference held by the FAA, the 727 SWG was made and included 727 airline operators from a large part of the high time 727 fleet, persons from the Boeing Company, and monitors from the FAA. The SWG examined the structural changes and inspections given in applicable Boeing service bulletins. A selection of these service bulletins was made that contain structural changes and inspections that are important to the continued structural airworthiness of 727 airplanes. The structural changes given in these service bulletins are recommended to be included, and the inspections are recommended to be a part of the regularly scheduled maintenance on applicable 727 airplanes.
The data given in Notice of Status Change 727-57-0112 NSC 1, 2 and 3 are included in this revision.
Paragraph I.A., Effectivity, shows changes of airplane operators. Each operator should examine the Effectivity paragraph for changes.
Vertical lines are put on the left edge of each page, except in Paragraph I.A., Effectivity, to show the location of important changes. Pages with a revision number and date, but no vertical lines, have no important changes.

Commercial Airplane Group 727 Service Bulletin Number: 727-57-0112 SummaryDate: September 2, 1970 Revision 5: July 31, 1997 ATA System: 5712 SUBJECT: WINGS - RIB UPPER CHORD AT BL 70.5 - INSPECTION, MODIFICATION, AND REPAIR
BACKGROUND The Structures Working Group (SWG) has examined the structural change and inspection in this service bulletin, and recommends that the change and inspection be included on 727 airplanes.
During a 727 primary fatigue test at Boeing, two cracks were found in the upper vertical flange of the wing-to-body rib upper chord at Body Station 760.
One crack in the rib upper chord was between the two aft fastener holes of the frame at Body Station
760.95. The other crack in the rib upper chord was immediately aft of the lower fastener hole in the frame.
To increase the fatigue life of the rib chord and to reduce the risk of repair and maintenance not scheduled, make the change given in this service bulletin.
ACTION (PRR 24791-R and PRR 24803-R) As recommended by the 727 SWG, make the Preventive Modification or Large Repair structural change given in the Accomplishment Instructions at or before the airplane collects a total of 60,000 flights, and make the inspection given in the Accomplishment Instructions, Part II.A.1, Inspection, at or before the airplane collects a total of 14,000 flights, or within 3,000 flights, whichever occurs later.
If no cracks are found, increase the hole diameter, cold work the hole, and install a new fastener in six places. Continue the inspection at regularly scheduled times as given in the Accomplishment Instructions, Part II.A.2, or B.1, Inspection. The approved time between one inspection and the subsequent inspection must not be more than 14,000 flights. To stop the inspection given in this service bulletin, do the preventive modification or large repair.
If cracks are found, make a change to the rib upper chord as given in this service bulletin.
EFFECTIVITY All 727 airplanes, divided into 2 groups.
MANPOWER See Service Bulletin
MATERIAL INFORMATION Boeing supplied kits and Operator supplied Parts.
