EASA AD 2018-0135R1
SUPERSEDED BY EASA AD 2022-0204
Summary
EASA Airworthiness Directive 2018-0135R1 is an updated directive addressing the inspection and replacement of Main Landing Gear (MLG) sliding tubes on Airbus A318, A319, A320, and A321 aeroplanes. It applies to specific MLG sliding tubes identified by part and serial numbers in Safran and Airbus service bulletins. The directive mandates repetitive inspections and corrective actions to prevent potential sliding tube failure that could lead to landing gear collapse.
What Changed
EASA Airworthiness Directive 2018-0135R1 revises the previous AD 2018-0135 by correcting the definition of 'Affected MLG shock absorber' to align with Safran publications. It retains prior inspection and replacement requirements while introducing updated inspection intervals and clarifications on affected parts and installation restrictions.
Why It Matters
This directive is critical for aviation professionals to ensure the structural integrity of the main landing gear on affected Airbus models. Detecting and addressing cracks in MLG sliding tubes prevents potential landing gear failure, which could cause aircraft damage and occupant injury. Compliance ensures continued airworthiness and regulatory adherence.
What To Do
Operators must perform detailed inspections of affected MLG sliding tubes within specified flight cycle limits or months after the directive's effective date and continue inspections every 5,000 flight cycles. Any detected cracks require immediate replacement of the sliding tube with a serviceable part. Full replacement of affected sliding tubes with non-affected parts must occur within 10 years of the directive's effective date. Installation of affected parts is prohibited from the effective date onward.
