SUMMARY
This summary is for information only and is not approved for modification of the aircraft.
A. MODIFICATIONS
MODIFICATION CLASSIFICATION
MAJOR None
MINOR None
NOTE: As per EASA IR 21, a minor change is one that has no appreciable effect on the
mass, balance, structural strength, reliability, operational characteristics affecting
the airworthiness of the product. All other changes are major changes.
B. REASON
(1) History
During maintenance check, it has been observed in the field some cases of Nacelle
Anti-Icing (NAI) forward bulkheads found with elongated holes. These locating holes
are used during the manufacturing process and have no structural function and
do not transfer any loads. In operation, the locating holes are closed by fasteners.
The fastener vibration can generate the elongated holes and it can reduce the NAI
performance.
(2) Objective/Action
This Service Bulletin gives instructions to inspect the 18 air inlet locating holes. The
aim of this inspection is to check if the existing fasteners have damaged the locating
hole.
This Service Bulletin is published to advise all operators of A350–900 and A350–1000
aircraft of Vendor Service Bulletin (VSB) Ref. ROHR INC (51563) VSB RA35071-029
which inspects the fasteners and holes located in the air intake forward bulkheads on
engines 1 and 2.
(3) Advantages
The accomplishment of this Service bulletin contributes to limit the risk of low
pretension in the fastener and the fastener vibration.
(4) Operational/Maintenance Consequences

F. APPROVAL
The technical content of this document is approved under the authority of the Design
Organisation Approval ref. EASA.21J.031.
If an aircraft listed in the applicability has a modification or repair embodied that is not
of AIRBUS origin, and which affects the content of this Service Bulletin, the operator
is responsible for obtaining approval by its airworthiness authority for any adaptation
necessary before incorporation of the Service Bulletin.
G. MANPOWER
The manpower estimates given in this Service Bulletin are based on the direct labor cost to
do the work. These estimates assume that the work will be done by experienced personnel,
and may need to be revised upwards to suit operator’s circumstances. The estimates do not
include the time to prepare, plan or inspect the work. Manufacture and procurement of parts
and tools, drying times for paints, sealants, etc., and general administration work are also
not included.
