EASA AD G-2022-0018
SUPERSEDED BY CAA UK AD G-2023-0004
Summary
Civil Aviation Authority Airworthiness Directive G-2022-0018 is a UK CAA directive addressing the inspection of the Main Landing Gear Sidestay Outer Link on BAe 146-301, BAe 146, and AVRO 146-RJ aeroplanes. It mandates detailed inspections for cracks and dimensional checks to ensure continued airworthiness of these aircraft models. The directive applies to all serial numbers and also to used Sidestay Outer Links before reinstallation.
What Changed
This directive supersedes CAA AD G-004-05-2001 and removes the previous allowance for continued flight with known cracks in the Sidestay Outer Link. It introduces more stringent inspection requirements using BAE Systems Alert Service Bulletin ASB.32-A189 and requires replacement of any parts found with cracks before further flight. The directive also expands the applicability to include used parts not currently installed on aircraft.
Why It Matters
This Airworthiness Directive is critical for operators and maintenance organizations as it addresses a potential unsafe condition that could lead to Main Landing Gear collapse and runway departure. Compliance ensures the structural integrity of the landing gear, enhancing flight safety and regulatory adherence. It also aligns UK regulations with FAA and EASA policies by prohibiting continued operation with known cracks.
What To Do
Operators must perform detailed inspections of the Main Landing Gear Sidestay Outer Link within 28 days of 1 November 2022 and repeat inspections every 2000 flight cycles thereafter, following ASB.32-A189 instructions. Any detected cracks or discrepancies require immediate replacement of the affected part before further flight. Used replacement parts must be inspected and found free of defects prior to installation unless they are new with zero hours/cycles time since new.
