Triumph Main Landing Gear Door Actuator Retrofit Program

Program details

A retrofit and inspection program is active to address a manufacturing quality issue affecting specific Main Landing Gear (MLG) Door Actuators (P/N 114122015) installed on A320 Family aircraft. Internal damage has been found in some actuators due to incomplete peening (locking) of a critical ring, which could compromise the performance of the unit during operation.

Objectives:

• Replace affected actuators identified in Airbus AOT A32N033-24 and Service Bulletin 114122-32-108
• Ensure airworthiness by confirming proper peening of the Locking Ring in the actuator
• Provide cost-free inspection, repair, or replacement of eligible units until 30 December 2026

Operators can choose one of the following inspection methods:

• X-ray or CT scan of the actuator to verify correct deformation (peening) of the Locking Ring
• Disassembly and visual inspection of internal components
• Return of actuators to an approved repair facility for full evaluation

AAR Component Services - Amsterdam, located in Hoofddorp, Netherlands, will coordinate logistics, inspections, and repairs for operators. Responsibilities include:

• Managing the flow of removed actuators between operators and the OEM (Triumph Aerospace UK)
• Supporting inspection by X-ray, CT, or disassembly based on SB 114122-32-108 procedures
• Providing test capabilities and issuing airworthiness confirmation
• Handling shipment tracking and communication with Triumph and airline customers
