# 767 Service Bulletin **Summary Number: 767-27-0203**  Date: June 25, 2007 Revision 1: February 21, 2008 ATA System: 2731 **SUBJECT:** FLIGHT CONTROLS - Elevator - Repetitive Mis-Rig Check **CONCURRENT REQUIREMENTS** Refer to Paragraph 1.B., Concurrent Requirements. **BACKGROUND** This service bulletin gives instructions to do repetitive checks of the elevator Power Control Actuator (PCA) rigging to determine if there is a mis-rig condition. As an alternative to Boeing Alert Service Bulletin 767-27A0169, the incorporation of Boeing Service Bulletin 767-27-0187 to replace or rework elevator PCA bellcranks combined with the repetitive check of the elevator PCA input rod assemblies recommended in Boeing Service Bulletin 767-27-0201 and the repetitive check of the elvator PCA rigging recommended in this service bulletin will prevent continued operation with yielded or failed shear rivets in a bellcrank assembly for the elevator PCA and will also allow for longer inspection intervals. Operators are currently required by the Federal Aviation Administration (FAA) Airworthiness Directive (AD) 2001-04-09 to do the 400 flight-hour repetitive check recommended in Boeing Alert Service Bulletin 767-27A0169. One operator reported the left elevator drooping during a preflight check. Examination of the elevator control system found sheared rivets in the left-inboard and center Power Control Actuator (PCA) bellcrank assemblies. The elevator single hydraulic system check required by a Certification Maintenance Requirement (CMR) may not detect yielded or failed shear rivets in the bellcrank assemblies for the elevator PCA. As a result, the FAA issued AD 2000-17-05 to mandate the accomplishment of the actions specified in Boeing Alert Service Bulletin 767-27A0166, dated August 17, 2000. Since the issuance of AD 2000-17-05, the FAA has received reports that several 767-200, 767-300, and 767-300F airplanes failed the one-time functional check of the shear rivets required by the AD. As a result, the FAA issued AD 2001-04-09 to mandate the accomplishment of the actions specified in Boeing Alert Service Bulletin 767-27A0169, dated November 21, 2000. A detailed design review found that the override device incorporated into the elevator PCA input rod assembly provides protection against malfunctions and non-normal PCA operation.This design review also found that the shear rivets are not needed.The completion of Boeing Service Bulletin 767-27-0187 to replace or rework elevator PCA bellcranks combined with the repetitive check of the elevator PCA input rod assemblies recommended in Boeing Service Bulletin 767-27-0201 and the repetitive check of the elevator PCA rigging recommended in this service bulletin is an alternative to the 400 flight-hour repetitive check recommended in Boeing Alert Service Bulletin 767-27A0169. Boeing Service Related Problem (SRP) 767-SRP-27-0128 is related to this service bulletin.
