AIRCRAFT SERVICE BULLETIN
Description

Group 1:

1. CONCURRENT REQUIREMENTS

None.

2. BACKGROUND

This service bulletin provides instructions to replace the Ram Air Turbine (RAT) Pump and Control Module

Assembly to prevent failure of the hydraulic pump at low air speed. The RAT Assembly provides an emergency source of electrical and hydraulic power for the primary flight control if the left, center and right main

hydraulic systems fail. Loss of the RAT Pump and Control Module Assembly could lead to loss of control

of the airplane when emergency power from RAT Assembly is needed. If this change is not incorporated

on the RAT Assembly and hydraulic power is lost on the left, right and center main hydraulic systems, then

the RAT Assembly may not provide sufficient hydraulic power which could result in the loss of many critical

control systems that are necessary for safe flight.

The supplier discovered that the RAT Assembly may fail at low airspeeds. The volume fuse on the RAT

Assembly may be accidentally activated in flight before the RAT is deployed. This may lead to improper

pump offloading when the RAT is needed. Testing from supplier concludes such issues could possibly occur

at airspeed below 180 knots equivalent airspeed. The new RAT Pump and Control Module Assembly includes

an updated volume fuse design. Incorporation of this service bulletin will improve reliability of the RAT Assembly.

Boeing Service Related Problem (SRP) 787-SRP-29-0102 is related to this service bulletin.

critical control systems that are necessary for safe flight.

The supplier discovered that the RAT Assembly may fail at low airspeeds. The volume fuse on the RAT

Assembly may be accidentally activated in flight before the RAT is deployed. This may lead to improper

pump offloading when the RAT is needed. Testing from supplier concludes such issues could possibly

occur at airspeed below 180 knots equivalent airspeed. The new RAT Pump and Control Module Assembly

includes an updated volume fuse design. Incorporation of this service bulletin will improve reliability of the

RAT Assembly.

Boeing Service Related Problem (SRP) 787-SRP-29-0102 is related to this service bulletin.

Issue 002 is sent to change the Boeing recommended compliance time from 12 months to 36 months.

Further analysis indicates that the compliance time can be extended to give operators more time.

4. Description

Replace the existing RAT Pump and Control Module Assembly or as an option, replace the RAT Assembly.

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.

7. Manpower

The table below shows an estimate of the task hours necessary to do this change for each plane. 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 inspect the work

– Time to cure the materials

– Time to make the parts

– Time to find the tools

4. These work instructions refer to procedures included in 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 "in accordance with" are included in the

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

5. If it is necessary to remove more parts for access, you can remove those parts. If you can get

access without removing identified parts, it is not necessary to remove all of the identified parts.

Jacking and shoring limitations must be observed.

6. This service bulletin includes functional test procedures for the systems changed by this service

bulletin. More functional tests can possibly be necessary in accordance with standard maintenance practices because of interruption to other airplane systems.

7. If shading is used, shaded areas in Tasks are to separate the non-critical and non-authoritative

information from the critical and authoritative information.

8. The compliance times for the actions in Step 2., Work Instructions are in Data Module SB B787-

service bulletin is mandated by an Airworthiness Directive (AD), then the steps identified as RC

must be done to comply with the AD. Alternative procedures for steps not identified with RC can

be used if the RC steps can still be done as specified, and the airplane can be put back in a

serviceable condition. An Alternative Method of Compliance (AMOC) is not necessary for deviations to steps that are not identified as RC.

2. WORK INSTRUCTIONS

A. Make a change to the Ram Air Turbine (RAT) assembly in accordance with the RAT Assembly Modification

instructions. As an option, replace the RAT assembly in accordance with the Option-RAT Assembly
