EASA AD 2019-0274
Landing Gear — Main Landing Gear Leg — Inspection
Summary
EASA Airworthiness Directive 2019-0274 is an airworthiness directive issued by EASA concerning the inspection of the main landing gear legs on DAHER Aerospace TB 20 and TB 21 aeroplanes. It mandates repetitive detailed inspections using magnetic particle methods to detect cracks in the main landing gear leg areas. This directive applies to all serial numbers of these aircraft models to ensure continued airworthiness and safety.
What Changed
This directive introduces mandatory repetitive special detailed inspections of the left-hand and right-hand main landing gear legs on TB 20 and TB 21 aeroplanes. It requires corrective actions if cracks are found, including rework and further inspections or contacting DAHER for approved repair instructions. No previous airworthiness directive is superseded by this AD.
Why It Matters
This directive is critical for aviation professionals because undetected cracks in the main landing gear legs could lead to structural failure and landing gear collapse, posing serious safety risks. Operators and maintenance organizations must comply to prevent potential damage to aircraft and injury to occupants. Compliance ensures continued airworthiness and regulatory adherence for affected aircraft.
What To Do
Operators must perform the first special detailed inspection before exceeding 16,000 landings or within 200 landings after 20 November 2019, whichever is later, and repeat inspections every 3,200 landings thereafter. If cracks are detected, immediate rework and follow-up inspections are required before further flight. In case of recurring cracks, operators must contact DAHER for repair instructions and comply within specified times.
