EASA AD 2021-0112
Wings — Main Landing Gear Support Structure Fuse Pins — Inspection
Summary
EASA Airworthiness Directive 2021-0112 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus A350-941 and A350-1041 aeroplanes. It mandates inspection of the main landing gear support structure fuse pins to ensure proper installation and security. The directive aims to prevent potential main landing gear collapse caused by incorrectly engaged or secured fuse pins.
What Changed
This new airworthiness directive introduces a one-time detailed inspection requirement for the right-hand and left-hand main landing gear trunnion block attachment fuse pins and their retaining pins on Airbus A350 aircraft. It also specifies corrective actions depending on inspection findings, including contacting Airbus for further instructions if multiple fuse pins are found missing or improperly secured.
Why It Matters
This directive is critical for aviation professionals as it addresses a safety risk that could lead to main landing gear collapse, potentially causing aircraft damage and occupant injury. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and safety. The directive also provides clear guidance on inspection and corrective actions, facilitating effective maintenance planning and risk mitigation.
What To Do
Operators of Airbus A350-941 and A350-1041 aircraft must perform a detailed inspection of the affected fuse pins within 500 flight cycles or 6 months from 29 April 2021, whichever occurs first. If any fuse pin is missing, migrated, or improperly secured, corrective actions must be taken before the next flight. In cases where multiple pins are affected, Airbus must be contacted for approved repair instructions.
