What to do
Operators of affected Airbus A380 aircraft must modify each affected flap track support before exceeding 8,800 flight cycles since the aircraft's first flight, following the instructions in the applicable Airbus Service Bulletins. For aircraft previously modified with earlier revisions of the service bulletins, additional work specified in the latest revisions must be completed before the same flight cycle threshold. Alternative methods of compliance may be approved by EASA upon request.
Summary
EASA Airworthiness Directive 2019-0127 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus A380-841, A380-842, and A380-861 aeroplanes. It mandates modifications to the trailing edge flap track #3 and #4 supports on both left-hand and right-hand wings to address structural concerns. The directive applies to all serial numbers except those with Airbus modification 77208 incorporated in production.
What changed
This directive supersedes EASA AD 2016-0189 and expands the applicability to include aircraft modified in-service or in production with previous modifications 75712 and 75713. It introduces additional work requirements for certain aircraft and extends the compliance time for the modification of the affected flap track supports. The modification changes the flap track fairing load path design and updates compression pads to ensure full aircraft life compliance.
Why it matters
This directive is critical for aviation professionals because it addresses a potential unsafe condition that could lead to failure and in-flight loss of wing trailing edge flap track supports, risking reduced control or damage to the aircraft. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and safety. The extended compliance time and additional work requirements affect maintenance planning and resource allocation.
