TITLE: WINGS - CENTER WING - ADD FASTENER CAP IN LOWER PANEL BELLY
FAIRING FITTINGS
SUMMARY
This summary is for information only and is not approved for modification of the aircraft.
A. MODIFICATIONS
MODIFICATION CLASSIFICATION
MAJOR  None
MINOR  120540L27248
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.
NOTE:  This modification is related to an airworthiness issue and has been re-classified and
confirmed by EASA as minor in accordance with EU Part 21.A.91. As such, this is
handled by Airbus under the Design Organisation Approval ref. EASA.21J.031.
B. REASON
(1) History
It has been reported that double overcoating sealant could be not applied during
production phase on some fasteners into the Center Wing Box (CWB) and Belly Fairing
junction for both Left Hand (LH) and Right Hand (RH) sides.
Furthermore, affected fasteners with Part Number (P/N) EN6115 code B are also
concerned by the potential risk of rotation.
The double overcoating is part of the protection to comply with Electro Magnetic
Hazard (EMH) requirement to avoid outgassing risk in the CWB area in case of
lightning strike.
(2) Objective/Action
The aim of this Service Bulletin is to replace affected fasteners by new ones with P/N
EN6115 code T and to perform double overcoating application by a Nut Cap.
The clamping of these fasteners, located between intrados panel and belly fairing
fittings at CWB lower panel, is part of the protection to comply with EMH.
(3) Advantages
The accomplishment of this Service Bulletin will prevent outgassing risk in the CWB
area in case of lightning strike, potential fuel leakage, and will ensure compliance with
EHM requirements.
(4) Operational/Maintenance Consequences

1 Recommendations for installation of trimmed caps in close proximity to a step / radius.
1.1 Fitment of caps in close proximity to steps where there is a radius larger than 3mm.
The following procedure shall be used in conjunction with Process and Material Specification
(PMS) 01-05-88 to install trimmed caps in close proximity to a step with a radius:
- The bearing face of the washer / fastener shall not extend beyond the tangent of the radius
i.e. the washer's bearing surface shall not 'ride-up' the radius.
- The base of the inner cap is permitted to ride-up the radius however:
o The hooks on the inner cap must be able to engage with the fastener; this may limit the
amount of ride-up that is possible but if cap trimming is made between the attachment
hooks of the inner cap (Figure 1) a greater amount of 'ride-up' onto the radius may be
possible.
o The trimming can encroach into the cavity of the inner cap but a gap of less than 0.25mm
between the cap and structure must be ensured to prevent ingress of sealant into the
inner cavity. This would be difficult to ensure without accurate measurement or trials
With these mitigations all caps can be installed in close proximity to all radius (over 3mm)
as long as the fastener bearing surface is not seated beyond the tangent of the radius.
- Less trimming is required on larger radii and no trimming would be ever need to be applied in
radii larger than 8mm.
- The outer cap rim and inner cap can be trimmed at an angle or vertical cut (Figure 2).
1.1.1 Procedure for Fitment of caps in close proximity to steps where there is a radius larger
than 3mm.
The following procedure should be used in conjunction with AIP 01-03-011to install trimmed caps
in close proximity to a step with a sharp corner or radius greater than 3mm:
1. Check the proximity of the fastener / hole to the radius tangent or face of the step.
2. Trim the cap to achieve a gap of 0.2 to 1mm between the trimmed face of the cap and face
of the step (Figure 3).
3. Apply adhesion promoter to the trimmed surfaces of the cap and carry out normal surface
preparation on the area around the fastener as per AIP101-03-011, allow promoter to dry for
the recommended time.
4. Install the cap; inject sealant until the exude is seen for the base of the cut area and around
the cap. This may require some additional sealant injection resulting in a slightly larger
bead around the periphery of the cap.
