Issued: 23 June 2017
Subject: Improved Oil Filler Door Latches on IAE V2500 Engines
Ref. Publications:
Airbus Service Bulletin (SB) A320-71-1061, original issue, dated 21 April 2015.
Goodrich Aerostructures SB V2500-NAC-71-0332, original issue, dated 04 March 2016, and
Revision 1, dated 27 August 2016.
Applicability:
Airbus A319-131, A319-132, A319-133, A320-231, A320-232, A320-233, A321-131, A321-231 and
A321-232 aeroplanes.
Description:
Occurrences were reported of oil servicing door damage or in-flight loss on Airbus A320 family
aeroplanes equipped with IAE V2500 engines. Investigations performed by Airbus and by the
nacelle supplier determined that the door can be closed with latches still in an intermediate
position. Consequently, an incomplete closure of the door may occur, barely detectable in service,
with some of the latches not properly engaged. This may result in differential pressure during
flight, causing a scooping/flutter effect and, eventually, loss or damage of the door.
A warning has been added in subtask 12-13-79-410-064-A of the affected Aircraft Maintenance
Manual, revision dated February 2010, stating: “Make sure that all latches are in the disengaged
position before the engine-oil-tank-servicing access panel is closed. If the latches are not correctly
disengaged before you close the access panel, it is possible to engage the latches incorrectly. This
may cause the access panel to break-off and cause injury”.
Subsequently, Airbus developed modification (mod) 155785 that allows installation of a new latch,
Part Number (P/N) HA2153-1, featuring an additional torsion spring and increased latch poundage,
to ensure it does not remain in an intermediate position whenever opened or incorrectly latched.
This modification is now part of the standard configuration for IAE V2500 installation and is
embodied during production on aeroplanes with Manufacturer Serial Number 6340, 6402 and
subsequent. This modification can be installed on aeroplanes in service by means of Airbus SB
A320-71-1061.
Since EASA SIB 2016-01 was issued, recommending accomplishment of Airbus SB A320-71-1061, it
has been determined that incorrect rigging may have been accomplished during production of a

limited batch of post-mod oil servicing doors, P/N 745-4043-509, which could impair the
effectiveness of Airbus mod 155785. Consequently, Goodrich Aerostructures, the manufacturer of
the affected oil servicing doors, issued SB V2500-NAC-71-0332, later revised, providing
instructions for inspection and, depending on findings, rigging of the affected oil service doors.
At this time, the safety concern described in this SIB is not considered to be an unsafe condition
that would warrant Airworthiness Directive (AD) action under Regulation (EU) 748/2012, Part
21.A.3B.
Recommendation(s):
For aeroplanes pre-mod 155785 and pre SB A320-71-1061: EASA recommends accomplishment of
Airbus SB A320-71-1061 and Goodrich Aerostructures SB V2500-NAC-71-0332.
For aeroplanes post-mod 155785 or post SB A320-71-1061: EASA recommends accomplishment of
Goodrich Aerostructures SB V2500-NAC-71-0332.
