# 767 Service Bulletin

**Number: 767-27-0200** 

### Summary Date: June 25, 2007 ATA System: 2731 **SUBJECT:** FLIGHT CONTROLS - Elevator - Repetitive Pogo Check

**CONCURRENT REQUIREMENTS** Refer to Paragraph 1.B., Concurrent Requirements.

**BACKGROUND** This service bulletin gives instructions to do repetitive pogo checks of the elevator Power Control Actuator (PCA) input rod assemblies. As an alternative to Boeing Alert Service Bulletin 767-27A0168, the incorporation of Boeing Service Bulletin 767-27-0186 to replace or rework elevator PCA bellcranks combined with the repetitive check of the elevator PCA input rod assemblies recommended in this service bulletin and the repetitive check of the elevator PCA rigging recommended in Boeing Service Bulletin 767-27-0202 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 767-27A0168. 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 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 767-27A0168, 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 767-27-0186 to replace or rework elevator PCA bellcranks combined with the repetitive check of the elevator PCA input rod assemblies recommended in this service bulletin and the repetitive check of the elevator PCA rigging recommended in Boeing Service Bulletin 767-27-0202 is an alternative to the 400 flight-hour repetitive check recommended in Boeing Alert Service Bulletin 767-27A0168. Boeing Service Related Problem (SRP) 767-SRP-27-0128 is related to this service bulletin.June 25, 2007 767-27-0200 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 6 of 30

**C. Reason** This service bulletin gives instructions to do repetitive pogo checks of the elevator Power Control Actuator (PCA) input rod assemblies. As an alternative to Boeing Alert Service Bulletin 767-27A0168, the incorporation of Boeing Service Bulletin 767-27-0186 to replace or rework elevator PCA bellcranks combined with the repetitive check of the elevator PCA input rod assemblies recommended in this service bulletin and the repetitive check of the elevator PCA rigging recommended in Boeing Service Bulletin 767-27-0202 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- 27A0168. 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 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 767-27A0168, 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- 27-0186 to replace or rework elevator PCA bellcranks combined with the repetitive check of the elevator PCA input rod assemblies recommended in this service bulletin and the repetitive check of the elevator PCA rigging recommended in Boeing Service Bulletin 767-27-0202 is an alternative to the 400 flight-hour repetitive check recommended in Boeing Alert Service Bulletin 767-27A0168. Boeing Service Related Problem (SRP) 767-SRP-27-0128 is related to this service bulletin. **D. Description** Do a pogo check of the input rod assembly on each of the six elevator PCAs.June 25, 2007 767-27-0200 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 23 of 30

**E. Compliance**

The FAA will possibly release an Airworthiness Directive related to this service bulletin. The Airworthiness Directive will make the compliance tasks and times given in this service bulletin mandatory. **F. Approval** This service bulletin was examined by the Federal Aviation Administration (FAA). The changes specified in this service bulletin comply with the applicable regulations and are FAA approved, as well as European Aviation Safety Agency (EASA)/Joint Aviation Authorities (JAA) approved for all EASA/ JAA approved airplanes listed in the service bulletin effectivity. This service bulletin and its approval were based on the airplane in its original Boeing delivery configuration or as modified by other approved Boeing changes. If an airplane has a non-Boeing modification or repair that affects a component or system also affected by this service bulletin, the operator is responsible for obtaining appropriate regulatory agency approval before incorporating this service bulletin. This service bulletin has been approved by the FAA. In addition, the Manager of the FAA Seattle Aircraft Certification Office approves the action (i.e. inspection or modification) defined in this service bulletin combined with the actions defined in Boeing Service Bulletins 767-27-0186 and 767-27-0202 as an alternative method of compliance to the requirements of paragraph (a) of AD 2001-04-09. All provisions of AD 2001-04-09 that are not specifically referenced in the above statement remain fully applicable and must be complied with. **G. Manpower** The table below shows an estimate of the task-hours necessary to do the pogo check for each airplane. This estimate is for direct labor only, done by an experienced crew. Adjust the estimate with operator task-hour data if necessary. The estimate does not include lost time. These are some examples of lost time: — Time to adjust to the workplace — Time to schedule the work — Time to examine the work Table 1: Check Operation of the Input Rod Assemblies of the Left and Right Elevator PCA
