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.

BOEING SERVICE BULLETIN 767-27-0200

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.

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

5. These work instructions refer to procedures included on other Boeing documents. When 

the words "refer to" are used and the operator has an accepted alternative procedure, 

the accepted alternative procedure can be used. When the words "as given in" are 

included in the instruction, the procedure in the Boeing document must be used.

B. WORK INSTRUCTIONS
