EASA AD 26-103 — Fuselage – Structural Parts / Joints – Modification / Reinforcement

Summary

EASA Airworthiness Directive PAD No. 26-103 is a proposed directive addressing structural modifications and reinforcements for Airbus A330 aeroplanes, including models A330-201 through A330-343 and their freighter variants. The directive targets fuselage structural parts and joints to prevent widespread fatigue damage. It applies to all manufacturer serial numbers of the affected aircraft.

What Changed

This new proposed Airworthiness Directive introduces mandatory modifications based on Airbus Service Bulletins to reinforce fuselage structural parts susceptible to widespread fatigue damage. It requires operators to comply with specific modification instructions and timelines detailed in the referenced service bulletins. The directive also clarifies procedures for contacting Airbus and compliance time adjustments relative to maintenance program triggers.

Why It Matters

This directive is critical for maintaining the structural integrity of Airbus A330 aircraft, preventing potential crack initiation and propagation that could lead to rapid depressurisation and occupant injury. Aviation professionals, including operators and maintenance organizations, must ensure timely compliance to avoid safety risks and regulatory non-compliance. It also impacts maintenance planning and resource allocation due to the required modifications and coordination with Airbus.

What To Do

Operators of affected Airbus A330 models must perform the required fuselage structural modifications within the compliance times specified in the Airbus Service Bulletins referenced by the directive. They must also follow instructions to contact Airbus when indicated before the next flight and adhere to any additional instructions provided. Compliance deadlines are tied to the service bulletin schedules, with a consultation period closing on 2026-10-07.
