Plain English Summary

5/10 complexity

This Airworthiness Directive requires Airbus A330 operators to inspect and, where needed, repair or replace wing leading-edge blow-down panels per EASA AD 2006‑0048; it applies to all A330s except aircraft already modified or with specified service bulletins (Applicability) and took effect 13 April 2006. It responds to reports of in‑flight panel loss from rivet and structural wear linked to vibration, bending and aerodynamic loads; its aim is to prevent panel loss and injury on the ground (Background). Compliance timing and methods are in the referenced EASA AD (Requirement).

AD/A330/56	Wing Leading Edge Blow-Down Panels	4/2006

Applicability:	All Model A330 aircraft; except aircraft with Airbus Service Bulletin (SB)A330-57-3091 embodied in service.This Directive is not applicable to aircraft on which all affected panel landing assemblies mentioned in SB A330-57-3091 have been replaced in accordance with:Modification 53383 or SB A330-57-3084.Modification 47249 or SB A330-57-3063.
Requirement:	Action in accordance with the requirements of EASA AD 2006-0048.
Compliance:	As specified in the Requirement document.
	This Airworthiness Directive becomes effective on 13 April 2006.
Background:	Several operators have reported the in-flight loss (full or partial) of leading edge blow-down panels at various positions along the wing. Investigation of the affected area revealed wear of the rivet slots, a complete shearing of the rivets or cracks on the horizontal flange of the landing angle. Analysis has concluded that the damage was related to wing vibration, wing bending affects and high aerodynamic uploads. The actions required by this Directive are intended to prevent loss of the blow-down panels and potential injury to personnel on the ground.
