EASA AD 2016-0035R1
SUPERSEDED BY EASA AD 2019-0243
Summary
EASA Airworthiness Directive 2016-0035R1 is a regulatory update affecting Airbus A340-211, A340-212, A340-213, A340-311, A340-312, and A340-313 aeroplanes. It mandates structural modifications and reinforcements to fuselage frames and joints to ensure continued airworthiness and compliance with damage tolerance requirements. The directive addresses modifications originally listed in Airbus A340 ALS Part 2 Section 3 and provides alternative modification solutions.
What Changed
This revision of EASA AD 2016-0035 introduces alternative modification methods for certain structural reinforcements and clarifies the applicability of specific actions, particularly Actions No.5 and No.11. It also updates compliance instructions to align with the latest AD writing standards without altering the technical content. The AD supersedes the original 2016-0035 and incorporates new Airbus Service Bulletins as acceptable alternatives.
Why It Matters
This directive is critical for aviation professionals as it ensures the structural integrity and safety of Airbus A340 aircraft by preventing crack initiation and propagation in fuselage frames. Operators and maintenance organizations must comply to avoid operating aircraft beyond validated structural maintenance thresholds, thereby mitigating risks related to fatigue and structural ageing. Compliance supports regulatory adherence and prolongs aircraft service life.
What To Do
Affected operators must modify their Airbus A340 aircraft within specified Structural Modification Point (SMP) compliance times, following the instructions in the referenced Airbus Service Bulletins or approved alternative methods. For actions without a specified Service Bulletin, operators must contact Airbus for approved instructions and complete modifications accordingly. Compliance deadlines vary by aircraft configuration and usage but must not exceed the SMP limits; some modifications allow a deferral period of up to 12 months after 9 March 2016 if thresholds were already exceeded.
