EASA AD 2018-0150
Landing Gear — Repaired Main Landing Gear Wheel Axles — Reduced Life Limit
Summary
EASA Airworthiness Directive 2018-0150 addresses the reduced life limits for repaired main landing gear (MLG) wheel axles on Airbus A330 and A340 aeroplanes. This directive applies to specific serial numbers and part numbers of MLG wheel axles repaired by three identified Maintenance Repair Organisations (MROs). It mandates identification and replacement of affected axles to ensure continued airworthiness.
What Changed
EASA AD 2018-0150 supersedes the previous AD 2017-0245 and introduces clarifications regarding affected aircraft models and compliance times. It retains all prior requirements but updates the post-repair life limits and compliance deadlines for MLG wheel axles repaired by the three MROs. Editorial changes were also made to align with current AD writing standards without altering technical content.
Why It Matters
This directive is critical for aviation professionals to prevent potential structural integrity issues caused by incorrect repairs on MLG wheel axles. Operators and MROs must ensure affected parts do not exceed the reduced life limits to avoid unsafe conditions. Compliance teams need to track and replace affected axles within specified deadlines to maintain regulatory compliance and aircraft safety.
What To Do
Operators must identify the part and serial numbers of all left and right-hand MLG wheel axles within 90 days after 25 December 2017. Affected axles must be replaced with serviceable parts within the compliance times specified in the directive's Appendix 1, depending on the MRO, aircraft type, and weight variant. Installation of affected axles repaired by the specified MROs is only permitted if the parts remain within the reduced life limits.
