REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES

During routine maintenance, two A321 aircraft Left Hand (LH) Main Landing Gear (MLG) Rib 5 forward

lugs were found ruptured. These had been previously modified as per Service Bulletin A320-57-1118

under Structural Repair Manual limits (Ref. ARS 57-0029).

The analysis of the first event has shown that a sealant discrepancy had led to water ingress and

then initiated corrosion, leading to cracking. The investigation of the second event has shown that a

remaining defect which was not removed during the repair had propagated, resulting in rupture of the

lug.

In order to maintain Continued Airworthiness of Single Aisle aircraft, a repetitive Detailed Visual

Inspection is introduced by Rev. 01 to Service Bulletin A320-57-1166 for all modified and/or repaired

aircraft.

Due to the similarity between MLG Rib 5 on A310 aircraft and that of the A320 aircraft family (same

design principle for the lug, same material, same modification or repair principles), a repetitive Detailed

Visual Inspection (DVI) or Ultrasonic Inspection (SDET) is also introduced by this Service Bulletin for

Gear Rib 5 lugs:

- Modified by Service Bulletin A310-57-2090 Rev. 00 to 02

- Repaired by Repair Instruction R57249121 Issue A to D.

This repetitive inspection will maintain Airworthiness of all aircraft modified by Service Bulletin and/or

repaired by Repair Instruction.

SERVICE BULLETIN

C. REASON

(1) History

During routine maintenance, two A321 aircraft Left Hand (LH) Main Landing Gear (MLG)

Rib 5 forward lugs were found ruptured. These had been previously modified as

per Service Bulletin A320-57-1118 under Structural Repair Manual limits (Ref. ARS

57-0029).

The analysis of the first event has shown that a sealant discrepancy had led to water

ingress and then initiated corrosion, leading to cracking. The investigation of the second

event has shown that a remaining defect which was not removed during the repair had

propagated, resulting in rupture of the lug.

(2) Objective/Action

In order to maintain Continued Airworthiness of Single Aisle aircraft, a repetitive Detailed

Visual Inspection is introduced by Rev. 01 to Service Bulletin A320-57-1166 for all

modified and/or repaired aircraft.

Due to the similarity between MLG Rib 5 on A310 aircraft and that of the A320 aircraft

family (same design principle for the lug, same material, same modification or repair

principles), a repetitive Detailed Visual Inspection (DVI) or Ultrasonic Inspection (SDET)

is also introduced by this Service Bulletin for Gear Rib 5 lugs:

- Modified by Service Bulletin A310-57-2090 Rev. 00 to 02

- Repaired by Repair Instruction R57249121 Issue A to D.

(3) Advantages

This repetitive inspection will maintain Airworthiness of all aircraft modified by Service

Bulletin and/or repaired by Repair Instruction.

(4) Operational/Maintenance Consequences

None

D. DESCRIPTION

NOTE: Operators have a choice to perform either a Detailed Visual Inspection (DVI)

or an Ultrasonic Inspection (SDET). Refer to the two separate tasks for each

Method.

To accomplish this Service Bulletin it is necessary to :

Task 572101-832-895-001: METHOD 1 - DETAILED VISUAL INSPECTION (DVI)

(1) Do a Detailed Visual Inspection (DVI)

Task 572101-832-896-001: METHOD 2 - ULTRASONIC INSPECTION (SDET)

(1) Do an Ultrasonic Inspection (SDET)

SERVICE BULLETIN

E. COMPLIANCE

(1) Classification

MANDATORY: Service Bulletin must be accomplished.

(2) Accomplishment Timescale

Threshold (since Modification/repair embodiment): 2500 Flight Cycles (FC)

Interval for Detailed Visual Inspection (DVI),

repetitive inspection:

775 FC

Interval for Ultrasonic Inspection (SDET), repetitive

inspection:

1,300

For aircraft having exceeded the threshold, a

grace period is permitted:

775 FC

This Service Bulletin has been classified Mandatory. It is expected that an Airworthiness

Directive (AD) published by the European Aviation Safety Agency (EASA) will be issued

to confirm this classification. It is anticipated that the AD will confirm the (thresholds

and/or intervals and/or date) given above but reference should be made to the AD for

confirmation of the mandated accomplishment timescale.

F. APPROVAL

The technical content of this document is approved under the authority of Design

Organization Approval No. EASA.21J.031.

If an aircraft listed in the effectivity 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.
