EASA AD 2019-0226
Landing Gear — Centre Landing Gear Wheel Axle — Replacement
Summary
EASA Airworthiness Directive 2019-0226 is an airworthiness directive addressing the replacement of centre landing gear wheel axles on Airbus A340-541, A340-542, A340-642, and A340-643 aeroplanes. The directive targets specific wheel axles with part numbers 55-1107065-00 and 55-1107069-00 that have been identified as affected due to corrosion found during overhaul. It mandates replacement of these affected parts to ensure continued airworthiness.
What Changed
This new airworthiness directive introduces a mandatory replacement requirement for certain centre landing gear wheel axles on Airbus A340 aircraft that were found to have corrosion caused by insufficient non-destructive testing during overhaul. It prohibits installation of these affected parts on any aircraft from the effective date and requires replacement within six years after the last known overhaul date.
Why It Matters
This directive is critical for aviation professionals because the affected wheel axles pose a risk of failure that could lead to damage to the aircraft and injury to occupants. Operators and maintenance organizations must ensure compliance to maintain aircraft safety and regulatory conformity. It also impacts parts management by restricting installation of affected axles.
What To Do
Operators of Airbus A340-541, A340-542, A340-642, and A340-643 aircraft must identify if their aircraft have affected centre landing gear wheel axles installed. For those that do, the affected parts must be replaced with serviceable parts within six years after the last known overhaul date. Additionally, from 25 September 2019, no affected part may be installed on any aircraft.
