as well as European Union Aviation Safety Agency (EASA)/Joint Aviation Authorities (JAA) approved for
all EASA/JAA approved airplanes listed in this Requirements Bulletin effectivity. This document and its
approval were based on the airplane in its original Boeing delivery configuration or as modified by other
Boeing changes.
If an airplane has a non-Boeing modification or repair that affects a component or system also affected by
this Requirements Bulletin, the operator is responsible for obtaining appropriate regulatory agency approval

E.    ACCOMPLISHMENT INSTRUCTIONS
1. GENERAL INFORMATION
NOTE: 1. This is an Enhanced Required for Compliance document. There will be a separate Service
Bulletin (SB) and a separate Requirements Bulletin (RB). If an RB is mandated by an
Airworthiness Directive (AD), then all applicable requirements specified in the RB must
be done. For the related SB, some locations are marked RC Start and RC End to identify
the requirements that are restated from the RB. For the related SB, the areas between
RC Start and RC End, including sub-steps and any figures identified between RC Start
and RC End, must be done to comply with the AD. Therefore, an Alternative Method of
Compliance (AMOC) is required for any deviations to steps between RC Start and RC
End, including substeps and identified figures. For the related SB, the steps not between
RC Start and RC End may be deviated from using accepted methods in accordance with
the operator's maintenance or inspection program without obtaining approval of an AMOC;
this is provided that the steps between RC Start and RC End, including sub-steps and
identified figures, can still be done as specified, and the airplane can be put back in an
airworthy condition. Figures not required for compliance are omitted from the RB.
2. This is an Enhanced Required for Compliance document. The Boeing processes used
to create the Service Bulletin (SB) and the Requirements Bulletin (RB) ensure that the
information between "RC Start" and "RC End" in the SB are identical to the information
in the same sections (Compliance, Work Instructions...) of the RB which the SB refers to
as the related document.
3. 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.
4. The compliance times for the actions in Work Instructions are in Compliance.
5. When more than one OPTION is given for a CONDITION, do only one of the OPTION
numbers. When more than one ACTION is given for a CONDITION number or an OPTION
number, do all of the ACTION numbers for that CONDITION number or OPTION number.
