TITLE: MAIN LANDING GEAR - INSPECTION OF THE HINGE ARM/BARRELPIN
**CONF ALL
MODIFICATIONS
None
REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES
Three cases of cracks on Main Landing Gear (MLG) Hinge Arm / Barrel Pin have been reported toAIRBUS. These cracks initiated on the inner diameter of the Hinge Arm / Barrel Pin following anoverload leading to the connecting rod bushings fracture.
Corrective actions are done in two steps:
- A clean-up of the fleet through MOD No. 13859S22952 (Service Bulletin No. A300-32-6120) forused pins replacement by a brand new pin with primer paint.
- A new repetitive inspection described in this Inspection Service Bulletin (ISB) that will be performedon the new pin with primer paint post MOD No. 13859S22952 (Service Bulletin No. A300-32-6120).
The aim of this procedure is to perform following inspection / maintenance actions on the aircraft onwhich MOD No. 13859S22952 (Service Bulletin No. A300-32-6120) is embodied:
- Remove MLG Hinge Arm / Barrel Pin with dedicated tooling
- Visually inspect MLG Hinge Arm / Barrel Pin and associated connecting rod bushings
. In case connecting rod bushings are found cracked, distorted or fractured, or the MLG HingeArm / Barrel Pin is found cracked, MLG Leg shall be removed and sent to MRO for inspectionwith the MLG Hinge Arm / Barrel Pin, other side MLG leg should be inspected before nextflight (as per this ISB)
. If the MLG Hinge Arm / Barrel Pin is found with damage (chrome damage, corrosion, cracks),send it to Safran Landing Systems for investigation
DATE: Sep 24/19 SERVICE BULLETIN No.: A300-32-6119
. In case of nil findings, re-install the same MLG Hinge Arm / Barrel Pin on aircraft.
- Repeat inspection within the defined compliance time.
The accomplishment of this Service Bulletin will prevent failures on the MLG Hinge Arm / Barrel Pin.The MLG Hinge Arm / Barrel Pin is a safe life item listed in ALS Part 1. Failure of the Hinge Arm /Barrel Pin could result in a MLG collapse.

- A new repetitive inspection described in this Inspection Service Bulletin (ISB) thatwill be performed on the new pin with primer paint post MOD No. 13859S22952(Service Bulletin No. A300-32-6120).
(2) Objective/Action
The aim of this procedure is to perform following inspection / maintenance actions onthe aircraft on which MOD No. 13859S22952 (Service Bulletin No. A300-32-6120) isembodied:
- Remove MLG Hinge Arm / Barrel Pin with dedicated tooling
- Visually inspect MLG Hinge Arm / Barrel Pin and associated connecting rodbushings
. In case connecting rod bushings are found cracked, distorted or fractured, orthe MLG Hinge Arm / Barrel Pin is found cracked, MLG Leg shall be removedand sent to MRO for inspection with the MLG Hinge Arm / Barrel Pin, other sideMLG leg should be inspected before next flight (as per this ISB)
. If the MLG Hinge Arm / Barrel Pin is found with damage (chrome damage,corrosion, cracks), send it to Safran Landing Systems for investigation
