B. REASON
(1) History
In production line, one too deep spot face was detected on Rib 1 at the level of the
front engine mount bolting on the pylon. A too deep spot face at this location leads
to potential integration issues between the pylon and the front engine mount. The
consequence is a reduced fatigue life with a potential unsafe condition that cannot
be ruled out. A production quality check has been conducted to conclude that the
batch of aircraft included in the applicability list of this Service Bulletin are potentially
impacted.
(2) Objective/Action
The objective of this Inspection Service Bulletin is to detect the potential too deep spot
faces on the Pylon Rib 1 at level of the 3 pylon bolt holes per pylon, and to provide the
inspection tasks and the repair input to clear the potential findings.

B. CONCURRENT REQUIREMENTS
CONF 001
Accomplishment of this Service Bulletin requires the simultaneous accomplishment of this
Service Bulletin:
Service Bulletin(s) Modification(s)
Ref. SB A350-71-P011 112589L85268
NOTE: Service Bulletin No. A350-71-P011 (POWER PLANT - MOUNTS - FRONT MOUNT
RETENTION BRACKET AND PYLON WASHER MODIFICATIONS ON ENGINE 1 (LH SIDE).
CONF 002 003
None
CONF ALL
C. REASON
(1) History
In production line, one too deep spot face was detected on Rib 1 at the level of the
front engine mount bolting on the pylon. A too deep spot face at this location leads
to potential integration issues between the pylon and the front engine mount. The
consequence is a reduced fatigue life with a potential unsafe condition that cannot
be ruled out. A production quality check has been conducted to conclude that the
batch of aircraft included in the applicability list of this Service Bulletin are potentially
impacted.
(2) Objective/Action
The objective of this Inspection Service Bulletin is to detect the potential too deep spot
faces on the Pylon Rib 1 at level of the 3 pylon bolt holes per pylon, and to provide the
inspection tasks and the repair input to clear the potential findings.

NOTE: It is recommended to perform this Service Bulletin at the opportunity of an
engine overhaul or engine replacement.
(3) Advantages
The implementation of this Service Bulletin in the affected A/C will minimize further
repairs due to a reduced fatigue life of the pylon attachment.
(4) Operational/Maintenance Consequences

NOTE: Manual titles given in the accomplishment instructions are referred to by acronyms. Refer
to paragraph 1.J., References, for the definition of acronyms.
NOTE: This Service Bulletin is classified mandatory or expected to be classified mandatory by

done as part of other actions or done with accepted methods different from those given
in the Service Bulletin, as long as the RC paragraphs can be done and the aircraft can be
put back into a serviceable condition.
NOTE: This Service Bulletin contains the instructions for the on-aircraft maintenance necessary
to ensure the continued airworthiness of the aircraft.
For any deviations to the instructions, including Required for Compliance paragraph
contained herein, contact AIRBUS for further instructions and approval.
