REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES

Corrosion of the Main Landing Gear (MLG) Rib 5 forward lugs is addressed by the production

modification 32025J2211. In service aircraft are addressed by the accomplishment of Service Bulletin

A320-57-1118 (Mod. No. 32025J2211) to install new increased interference fit bushes.

During routine maintenance, two through cracks were found on the Left Hand (LH) side of two MLG Rib

5 forward lugs on A321 aircraft that were previously modified as per Service Bulletin A320-57-1118

under Structural Repair Manual (SRM) limits.

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

corrosion, leading to cracking.

The investigation of the second case indicates that a remaining defect which was not removed during

the repair has started to propagate, resulting in rupture of the lug.

In order to maintain Continued Airworthiness of the affected aircraft, repetitive Detailed Inspection

requirements have been assessed and are applicable until a new terminating action for cracking is

defined.

The repeat inspections will make sure that cracks in the inspection area on the forward lug of the MLG

rib 5 fitting will be found at an early stage, thus preventing further damage.

(5) Configuration definition

**CONF 001

Config. 001 is valid for A318/A319/A320 and A321 aircraft that have:

- SB A320-57-1118 embodied

OR

- SRM 57-26-13 repair applied

OR

- Repair Instruction (RAS) applied.

**CONF 002

Config. 002 is valid for A318/A319/A320 and A321 aircraft that have had the MLG

Support Rib 5 Lugs replaced with a Post Production Mod 32025J2211 standard.

(6) Material Effectivity

MATERIAL QTY PER A/C SEE NOTES

Consumable CMLB01 As required

B. CONCURRENT REQUIREMENTS

None

C. REASON

(1) History

Corrosion of the Main Landing Gear (MLG) Rib 5 forward lugs is addressed by

the production modification 32025J2211. In service aircraft are addressed by the

accomplishment of Service Bulletin A320-57-1118 (Mod. No. 32025J2211) to install new

increased interference fit bushes.

During routine maintenance, two through cracks were found on the Left Hand (LH) side

of two MLG Rib 5 forward lugs on A321 aircraft that were previously modified as per

Service Bulletin A320-57-1118 under Structural Repair Manual (SRM) limits.

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

ingress and initiated corrosion, leading to cracking.

The investigation of the second case indicates that a remaining defect which was not

removed during the repair has started to propagate, resulting in rupture of the lug.

(2) Objective/Action

In order to maintain Continued Airworthiness of the affected aircraft, repetitive Detailed

Inspection requirements have been assessed and are applicable until a new terminating

action for cracking is defined.

(3) Advantages

The repeat inspections will make sure that cracks in the inspection area on the forward

lug of the MLG rib 5 fitting will be found at an early stage, thus preventing further
