EASA AD G-2023-0004R1
Landing Gear — Main Landing Gear Sidestay Outer Links (LH & RH) — Inspection / Lubrication
Summary
UK Civil Aviation Authority Airworthiness Directive G-2023-0004R1 addresses inspection and lubrication requirements for the Main Landing Gear Sidestay Outer Links (left-hand and right-hand) on all models and serial numbers of BAe 146 and AVRO 146-RJ aeroplanes. The directive mandates detailed visual and special detailed inspections for cracks and dimensional checks, as well as lubrication tasks to ensure continued airworthiness of these critical landing gear components.
What Changed
This revision introduces an additional alternative inspection method with longer intervals, modifies the repeat inspection requirements to include a special detailed inspection every 1200 flights or 12 months, and incorporates instructions for inspecting and restoring abrasion resistant paint near the inspection area. It also adds a calendar backstop for lubrication tasks and updates the one-off dimensional tolerance check requirements.
Why It Matters
This directive is crucial for aviation professionals to prevent potential failure of the Main Landing Gear Sidestay Outer Links, which could lead to landing gear collapse and runway excursions. Operators and maintenance organizations must comply to ensure aircraft safety and regulatory adherence, minimizing operational disruptions and avoiding costly repairs or incidents.
What To Do
Operators must perform the initial detailed visual or special detailed inspections within 28 days of 7 July 2023 and repeat inspections according to the specified intervals. A one-off dimensional check and lubrication of the sidestay outer link pivots must be completed within 3 months of 7 July 2023, with lubrication repeated every 500 flights or 6 months. Any discrepancies found require immediate replacement of the affected part before further flight.
