What to do
Operators of affected Airbus A330 and A340 aeroplanes must perform a detailed and special detailed inspection of the aft lug of each affected slat track within 24 months of 18 February 2019. If cracks are found, replacement with serviceable parts must occur before the next flight; if no cracks are found, replacement must be done within three months. Installation of affected parts is prohibited from the effective date onward.
Summary
EASA Airworthiness Directive 2019-0026 is an airworthiness directive addressing Airbus A330 and A340 aeroplanes. It focuses on the inspection and replacement of wing slat tracks number 10 installed on Slat 4 on both left and right sides, specifically parts with part numbers F574-64110-000 or F574-64110-002. The directive mandates inspections and replacement to ensure continued airworthiness and safety.
What changed
This new directive introduces a one-time detailed inspection and special detailed inspection of the aft lug of affected wing slat track parts, followed by mandatory replacement with serviceable parts if necessary. It also prohibits installation of the affected parts on any Airbus A330 or A340 aeroplane from the effective date. The directive addresses an unsafe condition caused by incorrect eligibility of certain parts in the Illustrated Parts Catalogue since 2010.
Why it matters
This directive is critical for aviation professionals because the affected wing slat tracks may not sustain ultimate load, risking slat detachment during flight and potentially leading to reduced aircraft control. Operators, maintenance organizations, and compliance teams must ensure inspections and replacements are completed within specified deadlines to maintain aircraft safety and regulatory compliance.
